Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Decadal changes in environmental suitability for the margay (Leopardus wiedii) under anthropogenic pressure in the Yucatán Peninsula

open access: yesConservation Science and Practice, Volume 8, Issue 4, April 2026.
This study evaluates how human activities impact margay (Leopardus wiedii) distribution in the Yucatán Peninsula, revealing habitat loss due to agriculture but also recolonization opportunities in abandoned lands. Species distribution models show range contraction (2010–2023), yet margays demonstrate resilience near disturbed habitats.

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

open access: yesEcological Entomology, Volume 51, Issue 2, Page 395-404, April 2026.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...
