Competitor Richness Outweighs Climate and Land Cover in Explaining Abundance Variation of a Neotropical Fruit Bat

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT Understanding which processes regulate spatial variation in species abundance across their ranges is key in ecology. Species abundances may be affected by several factors, such as climate, elevation, land cover, species interactions and habitat protection status. However, few studies have focused on these effects synergistically across species

DNA Methylation, Epigenetics, and Evolution in Vertebrates: Facts and Challenges

open access: yesInternational Journal of Evolutionary Biology, Volume 2014, Issue 1, 2014., 2014
DNA methylation is a key epigenetic modification in the vertebrate genomes known to be involved in biological processes such as regulation of gene expression, DNA structure and control of transposable elements. Despite increasing knowledge about DNA methylation, we still lack a complete understanding of its specific functions and correlation with ...

Review of the Bat Flies of Honduras, Central America (Diptera: Streblidae)

open access: yesJournal of Parasitology Research, Volume 2013, Issue 1, 2013., 2013
Streblid bat flies are obligate and host‐specific blood‐feeding ectoparasites of bats. While the bat flies of some American countries are well studied (e.g., Panama, Venezuela), little is known about Honduran Streblidae. Accumulation of substantial numbers of specimens, from several different collections, has enabled a relatively thorough treatment of ...
