“…Despite the seasonally limited availability of water, nearly 500 species of birds and mammals thrive in the CBR (Gómez‐Pompa & Dirzo, 1995; González‐Jaramillo et al, 2016). Small ponds and small rock pools play a crucial role to support such highly diverse fauna, especially during the dry season (Delgado‐Martínez et al, 2018; Sánchez‐Pinzón et al, 2020; Sandoval‐Serés et al, 2016). Dendrotelmata occur in the region but few reports document their use by the local vertebrates (e.g., Ateles geoffroyi ; Ojeda‐Martínez et al, 2016).…”

Using camera traps, we documented that 21 bird and 9 mammal species use water‐filled tree holes (dendrotelmata) in the seasonal tropical forest of the Calakmul Biosphere Reserve, in southern Mexico. These species visited dendrotelmata primarily for foraging and drinking. The overall use of dendrotelmata was equally frequent between dry and rainy seasons but drinking behavior increased among birds during the dry season. Abstract in Spanish is available with online material.

“…Most important aquatic ecosystems in the northern Neotropics include coastal, tectonic and volcanic lakes (crater lakes and maars), karst waterbodies including lakes, cenotes and aguadas (water accumulated in topographic depressions under canopy cover); flooded caves, (subterranean) rivers, permanent and ephemeral ponds (Brezonik and Fox 1974;Pérez et al, 2011a;Delgado-Martínez et al, 2018;Echeverría-Galindo et al 2019;Obrist-Farner and Rice, 2019).…”

Abstract. Geodiversity is recognized as one of the most important drivers of ecosystems characteristics and biodiversity globally. However, in the northern Neotropics, the contribution of highly diverse landscapes and geological history in structuring large-scale patterns of limnology and aquatic species associations remain poorly understood. We evaluate the interaction between geodiversity, limnology and freshwater ostracode assemblages to explore drivers of aquatic ecosystem structure from southern Mexico to Nicaragua. Cluster analysis based on geological, limnological, sedimentological and mineralogical characteristics of 76 aquatic ecosystems (karst, volcanic, tectonic) reveal two main limnological regions: (1) Karst terraces from the Yucatán Peninsula and northern Guatemala, and (2) volcanic terrains of the Guatemalan highlands, El Salvador and Honduras mid-elevations, and Nicaraguan lowlands. In addition, seven limnological subregions were recognized, attesting high limnological heterogeneity. Principal Component Analysis identifies water ionic and sediment composition as most influential for aquatic ecosystem classification and given their source of formation, we recognized geology as the fundamental determinant for large-scale limnological patterns. Multiparametric analyses based on biological data revealed that species association represent disjunct faunas. For instance, five species associations are closely related to limnological regions. Structural equation modelling reveals a strong influence of limnology and elevation on the biological composition, but geodiversity resulted in the most important driver. The confinement of species associations is attributed to regional lake geochemistry. We deduce a linear, continuous and primary influence of geodiversity for limnological structure, geochemical properties and aquatic biological composition in Lakes of the northern Neotropical region.

“…Many studies agree that the conservation of natural, free water sources and the construction of artificial water reservoirs are valuable strategies for wildlife conservation and management, not only in arid climate areas but also in areas with contrasting high seasonality (Martínez-Kú et al 2008;Delgado-Martínez et al 2018;Mandujano and Hernández 2019;Borges-Zapata et al 2020). Previous studies in Nicte Ha reported that the white-tailed deer responds to these contrasting environmental conditions by increasing the daily distances traveled and home range during the harshest portion of the dry season compared to the rainy season (Contreras-Moreno et al 2019a;Contreras-Moreno et al 2021).…”

Artificial Water Ponds (AWP) are widely employed for preserving and managing white-tailed deer (Odocoileus virginianus) in arid, and tropical regions of Mexico. However, there is a significant knowledge gap concerning the impact of these AWP on white-tailed deer activity. To determine the effect of AWP on the ecological aspects of white-tailed deer, we assessed the visitation rates and activity patterns of this species in AWP and compared them with areas devoid of water such as Dirt Roads (DR) using camera traps during the dry season within the seasonal wetland region of Nicte Ha, situated in western Campeche, Mexico. The research was conducted in a highly seasonal tropical wetland area at the Nicte-Ha UMA in southwestern Campeche, México. We established set camera trap stations during the dry season of 2019, 2020, and 2021 in seven AWP and 12 DR that operated for at least 80 days and compared the white-tailed deer visitation rate (measured as the Relative Abundance Index, RAI) and activity patterns among both treatments and across the three studied years. We collected a total of 3,640 independent records of white-tailed deer (2,584 in AWP and 1,056 in DR) for three years, with a combined effort of 3,978 camera days (1,306 camera days in AWP and 2,672 in DR). Our analysis revealed that the Relative Abundance Index (RAI) was consistently higher in the AWP than the DR across the three study years. However, we examined RAI variations over the three years and observed differences in the AWP, while the DR exhibited a relatively stable pattern. In the case of the activity patterns, we observed that white-tailed deer were primarily diurnal, with a significant overlap in activity between the two treatment areas. Nonetheless, within the AWP, the species exhibited continuous daytime activity, whereas, in the PR, distinct activity peaks occurred during sunrise and sunset. The results show that the presence of AWP in Nicte Ha has important effects on the presence of white-tailed deer during the dry season since we observed that there is a higher RAI in the sites where there is AWP compared to the PR sites. In the case of activity patterns, the AWP sites maintain constant activity throughout the day compared to DR, where activity peaks associated with sunrise and sunset occur. Our results show the importance that this type of structure has for the management of the species during the dry season of the year in Nicte Ha and the potential benefits of these structures in tropical seasonal areas, especially under a scenario in which drought during the dry season may be more severe in the near future due to the global change.
