“…This is most likely due to a long history of human selective pressure or filtering process which would have resulted in only tolerant species occupying this region at current times (Olden & Leroy Poff, 2004;Püttker et al, 2015). This is further supported by the lack of records of species of conservation concern, such as the jaguar (Panthera onca), tapir (Tapirus terrestris) or giant anteater (Myrmecophaga tridactyla), which have been reported in the region (Chacón-Pacheco et al, 2014;Montenegro et al, 2019), and confirms the capacity of some species to use landscapes with different levels of alteration and human presence, supporting other studies in anthropogenic landscapes (Boron et al, 2019;Ceballos et al, 2019;Daily et al, 2003;Hansen et al, 2020;Loock et al, 2018;Pardo et al, 2019;Perfecto & Vandermeer, 2008) Despite the apparent plasticity of species across the study area and the variability of responses, our results highlight the crucial role of forest cover for the presence of mammalian species regardless of its quality or the configuration of the landscape where patches are embedded, especially for herbivore species. The influence of forest size (at patch levels or the entire landscape) compared to forest quality and other aspects, such as configuration, has been an important debate in recent years (see Arroyo-Rodríguez et al, 2020;Villard & Metzger, 2014).…”

Human activities shape the structure of landscapes in different ways and hence modify animal communities depending on the type and intensity of these activities. Here, we used a multispecies occupancy model (MSOM) to understand mammalian habitat use patterns across a mosaic of tropical dry forest in Colombia and elucidate whether forest cover is more important than its integrity and other landscape configuration metrics. Surprisingly, our data suggest that none of the factors (including forest integrity) had a substantial effect on the mean community habitat use or species richness of mammals across the Montes de Maria, and there was no strong evidence to suggest any particular pattern in the distribution of functional groups in the landscapes. However, the percentage of forest cover was substantially important for herbivores, and consistently showed a moderate effect on the entire community, carnivores guild some individual species. There was high variability in the responses of each species to the examined variables that hinder us from broad generalizations, but in general, we also detected a moderate positive effect of forest cover in both diet specialists and generalists and species with small home ranges. Omnivores, on the other hand, tended to occupy more heterogeneous sites (moderate positive effects). The lack of substantial effects on most species and the absence of threatened species across this anthropogenic landscape suggests that the current community is composed of species tolerant to habitat modifications, but not only diet generalist species. This is most likely due to a long filtering process caused by land use transformation. However, our results highlight the relevance of conserving forest patches regardless of their level of modification or any other landscape attributes for maintaining assemblages of mammals.

“…We focus on three of the six species of WUS reported for the Orinoquian ecoregion: (i) lowland tapir (Tapirus terrestris) categorized as Vulnerable (VU) by the International Union for Conservation of Nature -IUCN, (ii) white-tailed deer (Odocoileus virginianus) Least Concern (LC), and (iii) white-lipped peccary (Tayassu pecari) Vulnerable (VU- Montenegro et al 2019). The three other species of WUS, the collared peccary (Diclotyles tajacu), red brocket deer (Mazama americana), and the Amazonian brown brocket deer (Mazama nemorivaga), have a limited number of records of occurrence for the native savanna ecosystems of Vichada.…”

“…In Colombia, twelve species of WUS are known, represented by three species of tapir, two peccary species, and seven species of deer. Of this diversity 50% of the species are reported in the HPNSL of the Orinoco basin, containing one tapir species, two peccary species, and three deer species (Montenegro et al 2019). The WUS are typically herbivorous and inhabit a wide range of diverse habitats (Wilson and Mittermeier 2011), and generally show high dispersal capacity, allowing individuals to nd suitable habitat.…”

Habitat connectivity of three threatened ungulate species in the high plains native savanna of northern South America

The high plains native savanna landscape (HPNSL) northeast of the Orinoco River is the habitat of 50% of the wild ungulate species (WUS) reported for Colombia. Over the last 20 years, this high species diversity has been strongly threatened by the accelerated human transformation of the natural land cover causing connectivity loss of the habitats. Despite this situation, the region lacks a biological connectivity analysis with a multi-species approach involving species groups that are representative of the savanna ecosystem such as the WUS. Understanding the spatial distributions of suitable habitats and the main habitats that act as primary habitats for ungulate focal species (UFS) in these landscapes is fundamental for the design of effective conservation strategies. Here, we use an occurrence dataset for Tapirus terrestris, Odocoileus virginianus, and Tayassu pecari in the development of species' potential distribution models, the binarization process, and morphological spatial pattern analysis. This information was used for the modelling of dispersal corridors connecting the core habitats of the UFS using the randomized shortest path algorithm and quantifying the weighted global connectivity metrics. Our results suggest an integral corridor with potential least-cost dispersal routes between the HPNSL on the middle and lower-middle basins of the savanna rivers and, to a lesser extent, the lower basin of the Meta River. These areas associated with the fluvial dendritic systems are connected, while the core habitats in the eastern part of the savanna landscape are largely disconnected. We discuss how the application of such knowledge on the spatial ecology of ungulate species might improve management of the metapopulations in the Colombian HPNSL.

“…Como es evidente, las metodologías para el inventario de mamíferos en la Amazonía van más allá de muestreos de cámaras trampa, los cuales se han preferido, sin mayor sustento técnico, a otras metodologías. El uso de cámaras trampa presenta importantes limitaciones en los inventarios de mamíferos, ya que la identificación de especies por fotos puede ser sesgada en grupos como los armadillos, marsupiales o roedores de mediano y pequeño tamaño (Ardillas, Myoprocta, Proechimys) e, incluso, los venados, cuya taxonomía y distribución están aún en discusión (Montenegro, et al, 2019). Por ejemplo, el género de roedores Proechimys es uno de los más complejos a la hora de identificar sus especies y exige la recolección y revisión de especímenes (Patton & Leite, 2015).…”

La Amazonía se considera una de las zonas con mayor diversidad de mamíferos a escala mundial. El conocimiento de dicha diversidad en Colombia es aún parcial y fragmentado. En ese contexto, se elaboró la lista de las especies de mamíferos conocidas y de las probables en la Amazonía colombiana a partir de la información contenida en la literatura especializada y en las bases de datos de biodiversidad. Se tuvieron en cuenta la división política-administrativa de la región y las tres provincias biogeográficas: Amazonía, Guayana y Norandina. Se evaluó la representatividad geográfica de los especímenes y se determinaron las áreas prioritarias para realizar inventarios y complementar el conocimiento actual de la diversidad de mamíferos en la región. Se registraron 265 especies de mamíferos: 94 en la provincia Norandina, 196 en la Amazonía y 183 en la Guayana. En los departamentos se ha registrado un rango de especies que va desde 26 en el Cauca hasta 157 en Caquetá y Putumayo. Del orden Chiroptera se registraron 137 especies, seguido por Rodentia, con 45 especies; en los otros órdenes se registraron entre una y 23 especies. Se encontró que la mayor parte del territorio está inexplorado y sin especímenes en las colecciones. Además, hay una gran probabilidad de que en la mayor parte del territorio de la Amazonía se encuentren, por lo menos, 70 especies no registradas, lo que la convierte en un área ideal para nuevos inventarios biológicos. Los resultados indican que la diversidad de mamíferos está subestimada y es necesario incrementar las exploraciones biológicas con el personal y la intensidad de muestreo apropiados, fortalecer colecciones biológicas e impulsar el uso de herramientas moleculares.
