Host–Parasite Interaction Networks of Helminths of Sigmodontine Rodents in Two Different Areas of the Brazilian Atlantic Forest

Ecological Research, Volume 41, Issue 3, May 2026.
Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...

Inferred presence of extraoral tissues in Triassic archosauromorphs and the evolutionary implications for the clade Sauropsida

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Recent work has suggested that the presence of extraoral soft tissues (‘lips’), in the form of labial scales in theropod dinosaurs, could be inferred based on: anteroposteriorly distributed foramina in the rostral bones, similar to extant lepidosaurs; vertically projected teeth; uniform enamel thickness in maxillary teeth; and an allometric ...

Four Novel Colletotrichum Species Associated With Anthracnose of Ornamental Araceae in Brazil With Insights Into Their Host Range

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Five ornamental Araceae with anthracnose symptoms, collected in Brazil, yielded four new species of Colletotrichum. These were described and named. Cross‐inoculations of those species on six aroids showed them to be non‐specific. ABSTRACT Araceae includes numerous flowering plant species that are cultivated as ornamentals in gardens, pots or by the cut‐

Testing the Limits of Morphology: A Comprehensive Morphometric Study of the Sister Lineages Lasiocyano Galleti‐Lima, Hamilton, Borges and Guadanucci, 2023 and Lasiodora C. L. Koch, 1850 (Theraphosidae, Mygalomorphae)

Journal of Morphology, Volume 287, Issue 4, April 2026.
An extensive morphometric framework combining linear and geometric morphometry was applied to evaluate interspecific differentiation within the Lasiocyano sazimai and Lasiodora lineage (Theraphosidae). Despite statistically significant differences in some analyses, extensive morphological overlap and high intraspecific variation consistently reduced ...
