abstract = {Due to the lack of in situ observations in mountainous locations, the use of remote sensing data is an alternative to analyze rainfall distribution patterns during the passage of major hurricanes. In this work, gridded precipitation data from the CHIRPS database are evaluated by comparing with observations from weather stations during the passage of category 3–5 hurricanes for the period 1980–2024. The comparison between estimated and observed values is performed by regression analysis and the use of K and K0 coefficients. An advantage of using K-ratio and K0-ratio is the identification of overestimated or underestimated precipitation in the pixel records. The distribution of daily precipitation helped in a more concise way to better understand how well CHIRPS reproduced the observed rainfall patterns. Results show that correlations between observations and database estimates are in the range of 0.40–0.76, for eastern Pacific hurricanes, and 0.49–0.78 for Atlantic hurricanes, all of which are statistically significant; however, these results do not imply congruence between observations and estimates since CHIRPS fails to adequately reproduce the position of the highest precipitation core. In the initial stages of a tropical cyclone, near-zero correlations between observations and estimates indicate that CHIRPS is not able to reproduce the observed rainfall. It is recommended to use CHIRPS with caution when the focus is on analyzing rainfall patterns during the development of intense tropical cyclones.},

 The fin whales ( 

 Balaenoptera physalus ) in the Gulf of California comprise a resident population genetically isolated from the rest of the North Pacific. The species occurs in the Eastern Midriff Islands Region (EMIR), in the central Gulf of California. The present study estimated fin whale abundance and apparent survival using photo‐identification data collected via weekly small‐boat surveys conducted from 2009 to 2017. In total, 1082 fin whales were recorded during 287 surveys that totaled 1924 h of research effort. After a photo comparison process of the dorsal fin, 376 unique individuals were identified, of which 180 had distinct features and high‐quality photos to be included in the mark‐recapture analysis. A mark ratio of 0.615 was obtained. A Jolly–Seber/POPAN mark‐recapture model yielded a superpopulation size of = 360 (SE 

 Un = 34.4, 95% CI [304–429]). The estimates for the years 2010–2016 were similar, from 178 (95% CI [185–363]) to 259 (95% CI [179–375]). A Cormack‐Jolly‐Seber model was used to estimate probability of survival. A hierarchical Bayesian time series analysis of encounter rates collected from 2012 to 2017 showed evidence of seasonality, with whales mostly present during the cold season (December–May), which coincides with the local upwelling regime. This information adds to the value of the EMIR as an important area for fin whale conservation in the Gulf of California.},

 Biologging has allowed collecting unprecedented detailed information about the biology and behavior of many species. GPS tracking technology has significantly advanced our understanding of gull ecology; however, research remains limited for endemic and tropical gull species. Here, we tracked Yellow-footed Gulls ( 

 Larus livens 

 ) at Gaviota Island in La Paz, Mexico, to obtain information on their habitat use and trip parameters between the early breeding (incubation and rearing small chicks), late breeding (large chicks and fledglings), and post-breeding period. During the early breeding period, Yellow-footed Gulls ( 

 n = 6) showed greater proportional use of at-sea habitats, spent less time away from their central location (h), and covered greater total trip distances (km). In contrast, the same individuals tracked during late breeding period ( 

 n = 5) showed greater proportional use of intertidal zones, spent more time away from their central location (h), and covered shorter total trip distances (km). During the post-breeding period ( 

 n = 4), gulls showed greater proportional use of human-altered habitats such as fishing ports, or aquaculture areas; and although gulls seldom traveled > 30 km, one individual moved > 200 km away from the colony. Differences in habitat use and trip parameters across periods were attributed to breeding requirements and prey availability. Although our sample size was small, this study furthers our understanding of the behavior of this poorly known endemic gull species from the Gulf of California.

 Zusammenfassung 

 Erste Studie über die Habitatnutzung und die Nahrungssuchflüge von Gelbfußmöwen 

 (Larus livens) 

 während der Brut- und Nachbrutzeit 

 Das Anbringen von kleinen elektronischen Geräten an Tieren (Biologging) hat uns beispiellos detaillierte Informationen über die Biologie und das Verhalten vieler Arten ermöglicht. Tracking mit GPS-Sendern hat unser Verständnis der Ökologie von Möwen erheblich verbessert. Allerdings gibt es nur wenige Studien zu tropischen, endemischen Möwenarten. In dieser Studie haben wir Gelbfußmöwen ( 

 Larus livens ) auf der Insel Gaviota in La Paz, Mexiko, besendert, um Informationen über ihre Lebensraumnutzung und Nahrungssuchflüge während der frühen Brutzeit (Brut und Aufzucht kleiner Küken), der späten Brutzeit (große Küken und Jungvögel) und der Zeit nach der Brutzeit zu erhalten. Während der frühen Brutzeit nutzten Gelbfußmöwen (n = 6) überproportional häufig Lebensräume auf See, verbrachten weniger Zeit außerhalb ihres zentralen Aufenthaltsortes (h) und legten insgesamt größere Entfernungen (km) zurück. Im Gegensatz dazu nutzten dieselben Individuen, die während der späten Brutzeit Daten gesendet haben (n = 5), die Gezeitenzonen proportional stärker, verbrachten mehr Zeit außerhalb ihres zentralen Standorts (h) und legten insgesamt kürzere Strecken zurück (km). In der Zeit nach der Brutperiode (n = 4) nutzten Möwen vermehrt von Menschen veränderte Lebensräume wie Fischereihäfen oder Aquakulturgebiete. Obwohl Möwen selten mehr als 30 km zurücklegten, entfernte sich ein einzelnes Tier mehr als 200 km von der Kolonie. Unterschiede in der Nutzung des Lebensraums und der Nahrungssuchflüge über verschiedene Zeiträume hinweg wurden auf die unterschiedlichen Anforderungen während der Brutzeit und die Verfügbarkeit von Beute zurückgeführt. Obwohl die Stichprobe gering war, trägt diese Studie zu einem besseren Verständnis über das Verhalten der bislang nur wenig untersuchten Gelbfußmöwe aus dem Golf von Kalifornien bei.},

abstract = {Abstract 

 Assessments of genetic diversity and population structure are essential for defining management units to prioritize conservation and management efforts. A susbspecies of the American oystercatcher ( 

 Haematopus palliatus frazari ) breeds in northwestern Mexico and is endangered due to its small population size, restricted distribution, and high vulnerability to anthropogenic activities. This study analyzed the genetic diversity and population structure of the American oystercatcher in six areas in northwestern Mexico. We used two molecular markers, the mtDNA control region and single nucleotide polymorphisms (SNPs), to calculate genetic diversity, population structure, the kinship coefficient, and migration rates among these geographic areas. Genetic diversity was high when calculated using mtDNA (h = 0.689) and relatively high for SNPs (h = 0.222). We identified genetic structure across geographic areas based on 1,889 SNPs. Individuals from the Baja California peninsula were genetically differentiated from those of the Sonora and Sinaloa populations. Indeed, the population of the Baja California peninsula can be considered a distinct demographic unit. This may be explained by high philopatry (low dispersal and recruitment of breeders) and regional habitat discontinuity (Sonora and Sinaloa were similar but different from the Baja California peninsula). Of note, the Bahia Santa María (Sinaloa) population serves as a source of individuals to other populations in the region. We recommend that conservation efforts prioritize major concentration sites, such as Bahia Santa María (Sinaloa), while also protecting smaller, isolated demographic units, such as the populations of Bahia de la Paz (Baja California Sur) and Bahia de Ceuta (Sinaloa).},

abstract = {Abstract 

 Population trends for shorebirds that spend the nonbreeding period of their annual cycle along the Pacific Americas Flyway are largely unknown. However, localized studies within the Pacific Flyway and analyses from the Atlantic Flyway suggest many shorebird species may be declining in the Western Hemisphere. Herein, we present the first trends of nonbreeding shorebirds along the Pacific Americas Flyway based on a coordinated survey effort from across a large portion of the Flyway. We used 10 years of survey data collected annually (2012–2013 to 2021–2022) between November and February from 10 countries along the Pacific Coast of the Americas to assess population trends for 22 species. There was a mix of positive and negative trend estimates across species. Overall, 10 of 22 species had a significant negative trend; 7 were significant at the P < 0.05 level and an additional 3 species showed evidence of significant decline at the P < 0.15 significance level. Two species evaluated were significantly increasing at P < 0.05. Of 17 species evaluated with regional models, the directionality of trend estimates by species was broadly consistent between the North Temperate and Neotropical regions of the Flyway. However, for 5 species the directionality of the trends differed between regions. Overall, species with uncertain trends generally had lower numbers of survey events and units included in the analysis because often they were affiliated with habitats with relatively limited sampling. While there was still uncertainty in the trend estimates for some species, we have strong evidence that some species were significantly declining, and at least a couple were increasing during our study period. Our results provide critical information to guide the prioritization of conservation investments and further investigations into the causes of shorebird declines, as well as increases, at regional and flyway scales along the Pacific Americas Flyway.},

Sin embargo, se sabe poco sobre cómo estos gremios estructuran su coexistencia bajo condiciones estacionalmente variables. En este estudio analizamos el uso temporal y espacial de aguajes por cinco especies de carnívoros medianos y pequeños (coyote, lince, zorra, zorrillo y mapache) en un ecosistema árido del noroeste de México, a lo largo de dos años. Se utilizaron nueve cámaras activas que, en 5,931 noches-trampa, registraron 4,060 visitas. Estimamos la frecuencia diaria de visitas, los patrones horarios de actividad, el solapamiento temporal y la coocurrencia espacial a lo largo del año y entre estaciones de secas y de lluvias, así como su relación con la diferencia de tamaño entre especies. Coyote, lince y zorra incrementaron su frecuencia de visita en temporada seca, mientras que el zorrillo la mantuvo y el mapache la redujo. Las especies se agruparon en dos periodos de actividad: crepusculares (coyote y lince) y nocturnas (zorra, zorrillo y mapache), con mayor solapamiento entre especies dentro de cada periodo y menor entre ambos. No se detectaron cambios estacionales significativos en los patrones de actividad horaria entre pares de especies. La coocurrencia espacial fue menor a lo esperado por azar en ambas estaciones, lo que indica una evitación activa del uso simultáneo de los aguajes. La diferencia de tamaño se relacionó negativamente con el solapamiento temporal únicamente en la estación de lluvias, pero no se asoció con la magnitud de la evitación espacial en ningún periodo. Estos patrones sugieren que la coexistencia de carnívoros en ambientes áridos se sostiene mediante ajustes conductuales que reducen la probabilidad de encuentros directos. La partición temporal y espacial operan como mecanismos complementarios para reducir los conflictos en torno a recursos hídricos críticos.

 In arid ecosystems, where water is scarce and localized, permanent waterholes are critical resources that concentrate the activity of terrestrial vertebrates and may intensify interactions among carnivores. However, little is known about how these guilds structure their coexistence around such sites under seasonally variable conditions. In this study, we analyzed the temporal and spatial use of waterholes by five species of medium- and small-sized carnivores (coyote, bobcat, gray fox, skunk, and raccoon) in an arid ecosystem in northwestern Mexico over two years. Nine camera traps recorded 4,060 detections across 5,931 trap-nights. We estimated daily visitation frequency, daily activity patterns, temporal overlap, and spatial co-occurrence among species throughout the year and between dry and rainy seasons, as well as their relationship with body size differences between speices. Coyotes, bobcats, and foxes increased their visitation rates during the dry season, while skunks maintained and raccoons reduced their visits. Species grouped into two main activity periods: crepuscular (coyote and bobcat) and nocturnal (fox, skunk, and raccoon), with high overlap within groups and moderate overlap between them. No significant seasonal changes were detected in activity patterns. Spatial co-occurrence was lower than expected in both seasons, indicating active avoidance of simultaneous use of waterholes. Body size differences were negatively related to temporal overlap only during the rainy season and showed no association with spatial avoidence. These patterns suggest that carnivore coexistence in arid environments is sustained through behavioral adjustments that minimize direct encounters. Temporal and spatial partitioning function as complementary mechanisms to reduce conflict over critical water resources.},

For the first objective, a drought analysis was performed using the Standardized Precipitation Index (SPI) at time scales of three (SPI-3) and 12 months (SPI-12), calculating seasonal (July-September) and annual (January-December) series. For the second objective, an EDP event was defined by filtering records greater than 30 mm from the selected stations, then adjusting them to a probability distribution to obtain the 99th percentile (P99) of each series. Values above P99 were identified as EDP events. The results indicate that drought events with large coverage (SPI-12) occurred under La Niña conditions in the 1989-1990 and 2011-2012 periods, affecting 71.4 and 64.3% of the state, respectively, where the coastal region was the least affected. A total of 57 EDP events were identified, but no particular ENSO pattern was determined. The most frequent peak activity occurred in 1987, 1999, 2010, and 2013, representing 31.6%, concentrated in 11 out of 28 climatological stations. While ENSO influences are weaker in these regions, other drivers, such as tropical cyclones, need adaptive disaster preparedness measures. Strengthening early warning systems, improving urban drainage infrastructure, and updating zoning regulations can mitigate flood impacts, reduce economic losses, and protect lives.},

abstract = {Introduction 

 Social-ecological systems (SES) recognize the intricate relationship between human activities and the environment and advocate for comprehensive approaches to address complex environmental issues. This study investigates the factors influencing whale watching, particularly the gray whale ( 

 Eschrichtius robustus 

 ) in northern Mexico, after significant recovery following overexploitation. Despite reaching a peak in 2015, the eastern North Pacific gray whales experienced unusual mortality events (UME), the most recent from 2019 to 2023, leading to a population decline and historically low calf production in 2022. This decline is evident in the reduced presence of whales and calves in winter breeding lagoons. Concurrently, whale watching has become a significant tourist attraction in these areas. 

 Methods 

 Our objective was to develop a mental model of the SES of gray whale watching, integrating ecological and socioeconomic data to identify key variables and interactions that support system resilience. From an ecological perspective, we analyzed the long-term temporal trends of eight years of gray whale counts in the southernmost breeding and nursing lagoons within the Bahía Magdalena–Bahía Almejas Complex, Mexico. Additionally, we incorporated the current discussion in the literature about the potential impact of global climate change on gray whale populations. In the socioeconomic subsystem, we used participatory methods, including interviews, surveys, and workshops with government officials, tourism operators, and visitors. We also added on-site assessments of compliance with welfare regulations to understand tourism dynamics. 

 Results 

 Our findings identified as main external stressors the changes in ice levels in feeding areas and sea warming in breeding areas, and as internal stressors the compliance with official regulations and the number of vessels observing whales at the same time. The key socioeconomic factor of the system was tourist satisfaction, influenced by factors such as the quality of the information provided by operators. 

 Discussion 

 Ultimately, our mental model provides a framework for further exploration of relevant interactions and trajectories, offering insights for developing effective management strategies.},

abstract = {This study aims to describe the response of two persistent chlorophyll-a maxima to physical processes that affect the po- sition of the thermocline/nitracline in the Eastern Tropical North Pacific (ETNP). We focused on Long Rossby Waves (LRWs) due to their relevance to the ETNP circulation and their potential role in introducing nutrients into the euphotic zone. We found that the shallower chlorophyll-a maximum in oxygenated waters became more intense when denser waters (containing more nu- trients) moved toward the surface. This suggests that changes in isopycnals and nitracline displacements modify nutrient supply in the euphotic zone, leading to changes in phytoplankton growth. The suboxic and deeper chlorophyll-a maximum showed a strong association with the 26 kg m-3 isopycnal, which was only mechanically displaced, and its chlorophyll-a content did not seem to covary with irradiance or nutrients. The decor- related responses of the chlorophyll-a maxima could be ex- plained if different phytoplankton groups are associated with them. LRWs can affect the position of the thermocline/nitracline and isopycnals in an annual cycle, but it seems to be a “back- ground” signal modulated by higher frequency processes such as mesoscale eddies and other Rossby waves. The co-occurrence of processes can control the nitracline depth, and thus the input of nutrients into the euphotic zone, leading to sporadic enhance- ments in chlorophyll-a concentration in one maximum.},

abstract = {A large amount of thermal energy is stored in the oceans between the tropics, available for conversion into electrical energy using OTEC technology. The aim of this study was to determine the annual and seasonal variability of the oceanic thermal resource in Mexico. Using the WOA18 database, we mapped surface temperature at a 10 m depth, deep cold water (<5 °C), vertical temperature difference (18 and 20 °C), and temperature anomalies. From the results, four areas were analyzed as being suitable for the installation of OTEC technology: Pacific (A), Los Cabos (B), Caribbean (C), and Gulf of Mexico (G). The optimal thermal resource (≥20 °C) was found between a 400 and 1000 m depth in all seasons in A and C, in spring, summer, and autumn in G, and only in summer and autumn in B. The suboptimal thermal resource (between 18 and 20 °C) was present between 400 and 800 m in all seasons in A, C, and G, and in summer and autumn in B. These results provide new information of utmost importance for future location and design considerations of OTEC plants on Mexican coasts, and the methodology can be used in other areas where there is a lack of field data and the development of OTEC technology is being considered.},

abstract = {Reinforcement Learning (RL) is a method that teaches agents to make informed decisions in diverse environments through trial and error, aiming to maximize a reward function and discover the optimal Q-learning function for decision-making. In this study, we apply RL to a rule-based water management simulation, utilizing a deep learning approach for the Q-learning value function. The trained RL model can learn from the environment and make real-time decisions. Our approach offers an unbiased method for analyzing complex watershed scenarios, providing a reward function as an analytical metric while optimizing decision-making time. Overall, this work underscores RL’s potential in addressing complex problems, demanding exploration, sequential decision-making, and continuous learning. External variables such as policy shifts, which are not readily integrated into the model, can substantially influence outcomes. Upon establishing a model with the requisite minimal states and actions, the subsequent learning process is relatively straightforward, depending on the selection of appropriate RL model algorithms. Its application depends on the specific problem. The primary challenge in this modeling approach lies in model definition, specifically in devising agents and actions that apply to complex scenarios. Our specific example was designed to address recent decision-making challenges related to constructing dams due to water scarcity. We present two examples: one from a nationwide perspective in Mexico and the other focused on Baja California Sur, the state with the highest water stress. Our results demonstrate our capability to prioritize watersheds effectively for the most significant benefits, particularly dam construction.},

 Yellowfin tuna, 

 Thunnus albacares 

 , represents an important component of commercial and recreational fisheries in the Gulf of Mexico (GoM). We investigated the influence of environmental conditions on the spatiotemporal distribution of yellowfin tuna using fisheries’ catch data spanning 2012–2019 within Mexican waters. We implemented hierarchical Bayesian regression models with spatial and temporal random effects and fixed effects of several environmental covariates to predict habitat suitability (HS) for the species. The best model included spatial and interannual anomalies of the absolute dynamic topography of the ocean surface (ADT 

 SA 

 and ADT 

 IA 

 , respectively), bottom depth, and a seasonal cyclical random effect. High catches occurred mainly towards anticyclonic features at bottom depths > 1000 m. The spatial extent of HS was higher in years with positive ADT 

 IA 

 , which implies more anticyclonic activity. The highest values of HS (> 0.7) generally occurred at positive ADT 

 SA 

 in oceanic waters of the central and northern GoM. However, high HS values (> 0.6) were observed in the southern GoM, in waters with cyclonic activity during summer. Our results highlight the importance of mesoscale features for the spatiotemporal distribution of yellowfin tunas and could help to develop dynamic fisheries management strategies in Mexico and the U.S. for this valuable resource.},
