Understanding the Hygienic Behavioral Dynamics of Ants Using Multi‐State Models

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 361-370, April 2026.
Leaf‐cutting ants adjust grooming to pathogen risk and vulnerable nestmates. Multi‐state Markov models reveal shorter, frequent self‐grooming bouts and reduced allogrooming persistence under stress, optimizing social immunity via stigmergic decision‐making.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

Ecological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Chemical defenses in the tree Ziziphus mistol against the leaf-cutting ant Acromyrmex striatus

Ecología Austral, 2002
Ziziphus mistol Griseb. (Rhamnaceae) trees are avoided by the leaf-cutting ant Acromyrmex striatus Roger (Formicidae, Attini) in a semi-arid Chaco forest of Santiago del Estero Province, Argentina.

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

Ecological 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 ...

Greater climate change adaptation potential in populations of Quercus macrocarpa at edges of latitudinal gradient

New Phytologist, Volume 250, Issue 2, Page 1313-1329, April 2026.
Summary With current climate trajectories, tree populations will encounter novel selection pressures that risk local extinction if they are unable to acclimate or adapt. Within a reciprocal transplant experiment with Quercus macrocarpa L. established across a latitudinal gradient, we asked: (1) Is there genetic variation within populations?

Lability in Hittite and Indo‐European: A Diachronic Perspective

Studia Linguistica, Volume 80, Issue 1, April 2026.
ABSTRACT Lability is defined as the possibility of a verb to enter a valency alternation without undergoing any change in its form. Labile verbs were common in ancient Indo‐European languages, including Hittite, which mostly features anticausative lability, with reflexive and reciprocal lability being less prominent.
