Producción científica sobre la herpetología en Colombia: perspectivas desde los temas de investigación hacia la conservación biológica

open access: yesCaldasia, 2022
La herpetología colombiana tiene más de 200 años de investigación, pero hasta el momento no se han sistematizado los documentos que conforman el estado del arte de esta disciplina.

The complete mitochondrial genome of Salamandra salamandra (Amphibia: Urodela: Salamandridae) [PDF]

open access: yesMitochondrial DNA Part B, 2016
The complete mitochondrial genome of Salamandra salamandra was reconstructed using bycatch sequences from an RNAseq library generated from muscle tissue. This study shows the potential of using data originally produced for transcriptome assembly to additionally generate complete mitochondrial genomes. The resulting mitogenome was circular, consisted of

Projecting the benefit of vericiguat in PARADIGM‐HF and DAPA‐HF populations: Insights from the VICTORIA trial

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1479-1484, April 2025.
Abstract Aims The VICTORIA trial demonstrated a significant reduction in the primary composite outcome of heart failure (HF) hospitalization or cardiovascular death with vericiguat relative to placebo in high‐risk HF. This study aimed to contextualize treatment effects of vericiguat in populations with varying risk profiles simulated from the PARADIGM ...

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

open access: yesIntegrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Contextually conspicuous species are more likely to be venomous: Habitat‐dependent aposematic colouration found throughout snakes

open access: yesJournal of Animal Ecology, Volume 95, Issue 11, Page 2322-2334, November 2026.
Conspicuous colouration signals venomous nature throughout snakes. Abstract Many animals use conspicuous colours to advertise their unprofitability to potential predators, a phenomenon known as aposematism. For example, conspicuous banded patterns in snakes are often highlighted as aposematic signalling of their venomous nature.

When One Matters More: Keystone Niche Individuals Shape Population‐Level Niches in Ectothermic Vertebrates

open access: yesJournal of Zoology, Volume 330, Issue 2, Page 131-141, October 2026.
The recently proposed concept of Keystone Niche Individuals, that is, individuals that disproportionately influence their population's niche width, provides a framework to explore how individuals shape ecological niches. We applied this framework to a dataset of 482 salamanders across 21 populations and seven taxa to assess the prevalence and ...

Native and Invasive Crayfish Species Impact on the Development of Fire Salamander Larvae: A Pilot Field Study From Northern Italy

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT In northern Italy, the ongoing spread of non‐native red‐swamp crayfish Procambarus clarkii keeps indirectly decimating native populations of white‐clawed crayfish Austropotamobius pallipes complex and is now also threatening local amphibians adapted to slow‐flowing, hilly streams at the borders of its distribution.

Unraveling the drivers of amphibian community distribution at a lowland–mountain interface: A joint modeling approach

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Understanding how environmental and biotic processes jointly shape species distributions and community composition is a central goal in ecology. Although species distribution models (SDMs) have become essential tools for quantifying environmental drivers of occurrence, their single‐species framework limits inference about interspecific ...
