Vázquez-Rueda, E., A. P. Cuervo-Robayo, and J. Ayala-Berdon. 2023. Forest dependency could be more important than dispersal capacity for habitat connectivity of four species of insectivorous bats inhabiting a highly anthropized region in central Mexico. Mammal Research. https://doi.org/10.1007/s13364-023-00707-0
The maintenance, restoration, and improvement of habitat structure are critical for biodiversity conservation. Under this context, studies assessing habitat connectivity become essential, especially those focused on anthropized regions holding high species richness. We calculated the habitat connectivity of four species of insectivorous bats with different dispersal capacity and habitat preferences in a highly anthropized region in central Mexico, Idionycteris phyllotis and Myotis thysanodes , with a high dispersal capacity and forest-dependency, and Eptesicus fuscus with a low dispersal capacity, and Tadarida brasiliensis with a high dispersal capacity, as the more tolerant bat species to anthropogenic disturbance. We developed niche-based species distribution models to identify suitable habitat patches for each species. We then assessed habitat connectivity and the importance of suitable habitat patches for maintaining connectivity using a graph theory approach. Our results showed that forest dependency was most important than dispersal capacity for connectivity. We also found that the Iztaccíhuatl-Popocatépetl mountain, a National Park comprising 4.2% of natural vegetation in the study area, was the most critical patch for maintaining connectivity for most of the study species. Our study demonstrates the importance of conserving the remnants of natural vegetation for maintaining habitat connectivity within a fragmented landscape and demonstrates the importance of conserving protected areas as well as other remnants of vegetation for the maintenance of habitat connectivity within a fragmented landscape.

Hummingbirds are one of the most threatened bird groups in the world. However, the extent to which global climate change (GCC) and habitat loss compromise their conservation status remains unclear. Herein, we proposed to: (1) assess how predicted GCC impacts the distribution of non-migrant hummingbi…

During the Quaternary, large climate oscillations impacted the distribution and demography of species globally. Two approaches have played a major role in reconstructing changes through time: Bayesian Skyline Plots (BSPs), which reconstruct population fluctuations based on genetic data, and Species …

Although vanilla is one of the most popular flavours in the world, there is still uncertainty concerning the native distribution of the species that produces it, Vanilla planifolia. To circumscribe the native geographical extent of this economically important species more precisely, we propose a new…

Insights for protection of high species richness areas for the conservation of Mesoamerican endemic birds A. Hughes [ed.],. Diversity and Distributions 27: 18–33. https://doi.org/10.1111/ddi.13153
Aim: To assess the representativeness values of Mesoamerican endemic birds within the current network of protected areas (PAs) to determine high‐priority and complementary conservation areas to maximize the long‐term protection of species. Location: From central Mexico to southern Panama. Methods:…

Understanding the spatial and temporal evolution of biota in the tropical Andes is a major challenge, given the region’s topographic complexity and high beta diversity. We used a network approach to find biogeographic regions (bioregions) based on high-resolution species distribution models for 151 …

La distribución del loro frente blanca, Amazona albifrons, en México incluye la vertiente del Pacífico y del golfo, desde Sonora y el sur de Veracruz, respectivamente, y continúa hasta Costa Rica. Recientemente, se ha registrado más allá de su área de distribución histórica conocida, aparentemente p…

Aim: Estimating the strength of niche conservatism is key for predictions of invasion risk. Most studies consider only the climatic niche, but other factors, such as human disturbance, also shape niches. Whether occupation of human habitats in the alien range depends on the native tolerances of spec…

Connecting the geographical occurrence of a species with underlying environmental variables is fundamental for many analyses of life history evolution and for modeling species distributions for both basic and practical ends. However, raw distributional information comes principally in two forms: poi…

Perspectives in Ecology and Conservation 18: 19–30. https://doi.org/10.1016/j.pecon.2020.01.002
We assessed the effects of global climate change as a driver of spatio-temporal biodiversity patterns in bird assemblages associated to Neotropical seasonally dry forests (NSDF). For this, we estimated the geographic distribution of 719 bird species under current and future climate (2050 and 2070) p…
