Changes in the nocturnal activity of birds during the COVID?19 pandemic lockdown in a neotropical city.

The COVID?19 lockdown provided the opportunity to measure species biodiversity in urban environments under conditions divergent from regular urban rhythms. For 90 days, including weeks of strict lockdown and the subsequent relaxation of restrictions, we measured the presence and ...

Role of the Chicamocha River Canyon on the phylogeography of humid montane forest birds in Colombia.

Neotropical humid montane forest (HMF) is divided by landform discontinuities which could limit gene flow among populations. The northern Andes is a complex montane system and an excellent region to compare the role of discontinuities dividing HMFs on the phylogeography of bird s...

Experiences of surveying urban birds during the anthropause in Colombia.

The COVID-19 lockdowns produced a singular opportunity to perform scientific research in idle cities. The expected changes in urban ecology led us to form a citizen science community which, following standardized protocols, conducted well-structured surveys of birds across Colomb...

Global COVID-19 lockdown highlights humans as both threats and custodians of the environment.

The global lockdown to mitigate COVID-19 pandemic health risks has altered human interactions with nature. Here, we report immediate impacts of changes in human activities on wildlife and environmental threats during the early lockdown months of 2020, based on 877 qualitative rep...

Diversification and secondary contact in the magpie-jays (Calocitta) throughout the pacific lowlands of Mesoamerica.

The Mesoamerican dry forests (MDF), rich in species and in endemic taxa, are distributed nearly continuously nearly continuously along the American Pacific slope from Mexico to Costa Rica; however, several of the bird species inhabiting the MDF show clear phenotypic differentiati...

New voucher specimens and tissue samples from an avifaunal survey of the Middle Magdalena Valley of Bolívar, Colombia, bridge geographical and temporal gaps

ABSTRACT Several of the first avifaunal surveys in Colombia were conducted in the lowland moist forests of the Middle Magdalena Valley, but for decades this region has been understudied. We present results of an avifaunal survey in a zone of Cantagallo, Bolívar, Colombia (Jun?J...

RELICT HUMID TROPICAL FOREST IN MEXICO PROMOTES DIFFERENTIATION IN BARRED WOODCREEPERS Dendrocolaptes (AVES: FURNARIIDAE)

Humid tropical forests in Mesoamerica are distributed along the Atlantic slope and, in scattered locations, along the Mexican Pacific slope. These poorly explored Mexican forests include microendemic bird species. Two species in the genus Dendrocolaptes occur in lowland and footh...

Body mass data set for 1317 bird and 270 mammal species from Colombia

Body mass is one of the most important phenotypic attributes in animal ecology and life history. This trait is widely used in the fields of ecology and macroevolution, since it influences physiology, morphological functions, and a myriad of ecological and social interactions. In ...

Defining the phylogeographic relationship between cis- and trans-Andean populations of Dendrocincla fuliginosa and Xenops minutus in Colombia

Due to the position of Colombia between Central and South America, and the presence of several ecosystems in its territory, phylogeographic information from populations across this country is fundamental to understand theevolutionary history of widespread Neotropical species. The...

ON BIRDS OF SANTANDER-BIO EXPEDITIONS, QUANTIFYING THE COST OF COLLECTING VOUCHER SPECIMENS IN COLOMBIA

Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of spec...
