Genotype‐by‐environment interaction informs selection for seed physiological quality and stink bug tolerance in soybean under pest management contrasts

open access: yesPest Management Science, Volume 82, Issue 9, Page 8530-8544, September 2026.
Genotype‐by‐environment interaction shaped soybean seed stability under contrasting insecticide regimes. Seed longevity emerged as a stable, management‐relevant trait under pest pressure. High‐pressure, no‐insecticide conditions improved discrimination of tolerant genotypes for integrated pest management deployment.

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1737-1746, September 2026.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

Micro‐CT informed cranial anatomy of the early rhynchosaur Howesia browni, with implications for rhynchosaur skull evolution

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Rhynchosaurs are unusual archosauromorph reptiles that lived between the Induan and early Norian (Early to early Late Triassic). They are characterized by their stocky build and broad skull with a beak‐like premaxilla. This rather charismatic configuration is most clearly expressed in Late Triassic hyperodapedontine rhynchosaurids.
