Environmental and Anthropogenic Predictors Influence the Diversity of Nonflying Mammals in a Native Savanna Landscape of Northern South America

open access: yesInternational Journal of Zoology
The native savannas of eastern Colombia cover about six percent of the Neotropical savannas. Within these 17 million hectares, the current composition of nonflying mammals evidenced colonization from Andean, Guyanese, and Amazonian speciation centers and

Detecting mass mortality events in wildlife populations. [PDF]

open access: yesConserv Biol
Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

Inhibitor-induced dimerization mediates lufotrelvir resistance in mutants of SARS-CoV-2 3C-like protease. [PDF]

open access: yesProtein Sci
Abstract The emergence of SARS‐CoV‐2 and other lethal coronaviruses has prompted extensive research into targeted antiviral treatments, particularly focusing on the viral 3C‐like protease (3CLpro) due to its essential role for viral replication. However, the rise of drug resistance mutations poses threats to public health and underscores the need to ...

One-class land-cover classification using MaxEnt: the effect of modelling parameterization on classification accuracy [PDF]

open access: yesPeerJ, 2019
Multiple-class land-cover classification approaches can be inefficient when the main goal is to classify only one or a few classes. Under this scenario one-class classification algorithms could be a more efficient alternative. Currently there are several

The adaptive cycle and the ecosystem services: a social-ecological analysis of Chiloé Island, southern Chile

open access: yesEcology and Society, 2020
We used the adaptive cycle as a heuristic to conceptualize the changes in ecosystem services between its phases (growth, conservation, collapse, and reorganization) for Chiloé Island (southern Chile), analyzed as a social-ecological system.

Scalar Field Evolution at Background and Perturbation Levels for a Broad Class of Potentials

open access: yesFortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023
Abstract In this paper, a non‐interacting scalar field cosmology with an arbitrary potential using the f‐deviser method that relies on the differentiability properties of the potential is investigated. Using this alternative mathematical approach, a unified dynamical system analysis at a scalar field's background and perturbation levels with arbitrary ...
