Parasite–Host Associations in Pinworms (Trypanoxyuris spp.) From Spider Monkeys (Ateles spp.)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 8, August 2026.
Lineages in pinworms from Ateles monkeys are highly host‐specific and their diversification patterns reflect host biogeographic and evolutionary histories. ABSTRACT Pinworms of primates are highly host‐specific parasites that, in several lineages, are known to share their evolutionary history with that of their hosts.

Revisiting the nomenclature of Carludovica microcephala, type species of Dicranopygium (Cyclanthaceae)

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The name Carludovica microcephala, basionym of the type species of Dicranopygium (Cyclanthaceae), has long been attributed to J.D. Hooker (1892), based on plants cultivated at the Royal Botanic Gardens, Kew. A reassessment of nineteenth‐century horticultural literature shows that the name had already been validly published 35 years earlier, in

High‐Throughput DNA Barcoding Reveals Multi‐Trophic Networks of Plants, Leafminers and Parasitoids in a Tropical Dry Forest

open access: yesMolecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT Tropical dry forests host highly diverse insect communities and complex trophic interactions, yet these networks remain difficult to resolve using conventional molecular or rearing‐based approaches. Here, we integrate long‐read DNA barcoding, non‐target sequence co‐amplification, and host plant taxonomy to reconstruct tri‐trophic interactions ...

Thermophilization: Concepts, Methods, and Implications of Changes in Community Composition due to Global Warming

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
As many species shift their geographic ranges coldward due to global warming, communities will undergo “thermophilization”—the increasing relative abundance of warm‐adapted (“thermophilic”) species and the concomitant decrease of cold‐adapted species over time.

Valuing Behavioral By‐Products: Evolutionary Significance of Neutrally Drifting and Exaptive Cultures in Primates

open access: yesAmerican Journal of Primatology, Volume 88, Issue 7, July 2026.
Structural, functional, and evolutionary links between two behavioral by‐products (i.e., stone play and female‐to‐female mounting—FFM) and their putative corresponding behavioral adaptations (i.e., stone tool use and female‐to‐male mounting—FMM) in Balinese long‐tailed macaques and Japanese macaques.
