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 ...

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 ...

Identifying socioeconomic and biophysical factors driving forest loss in protected areas

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Protected areas (PAs) are a commonly used strategy to confront forest conversion and biodiversity loss. Although determining drivers of forest loss is central to conservation success, understanding of them is limited by conventional modeling assumptions.

Measurement of actual evapotranspiration in a páramo ecosystem using portable closed chambers: Comparison between giant rosettes, tussock grasses and shrubs

open access: yesEcohydrology, Volume 16, Issue 4, June 2023., 2023
Abstract The páramos are Neotropical alpine tundra‐like ecosystems that play a crucial role as biodiversity hotspots and also act as water sources for the inter‐Andean regions and cities. Improving our understanding of hydrological processes, here evapotranspiration, is crucial, especially in the context of global changes.

Evenness mediates the global relationship between forest productivity and richness

open access: yesJournal of Ecology, Volume 111, Issue 6, Page 1308-1326, June 2023., 2023
Collectively, these results demonstrate that evenness is an integral component of the relationship between biodiversity and productivity, and that the attenuating effect of richness on forest productivity might be partly explained by low evenness in speciose communities.

Genómica en la producción animal

open access: yesRevista Colombiana de Ciencia Animal Recia, 2013
El mejoramiento genético evalúa y utiliza la variación genética para mantener y mejorar cualitativa y cuantitativamente la producción animal. La identificación de animales con altos méritos genéticos se dificulta por el hecho que la mayoría de las ...

Development and Evaluation of a Comprehensive Atmospheric Emission Inventory for Air Quality Modeling in the Megacity of Bogotá

open access: yesAtmosphere, 2018
We built an emission inventory (EI) for the megacity of Bogotá, Colombia for 2012, which for the first time augments traditional industrial and mobile sources by including commercial sources, biogenic sources, and resuspended dust.

Integración de analogías en la modelación científica

open access: yesRevista Colombiana de Filosofía de la Ciencia, 2018
La discusión sobre modelación científica se ha centrado en la relación representacional entre el modelo, como producto terminado, y un supuesto sistema diana en el mundo. Esta aproximación tiene algunos problemas para dar cuenta de procesos de modelación
