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

open access: yesEcological 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 ...

Floral biology of Stachytarpheta maximiliani Scham. (Verbenaceae) and its floral visitors Biologia floral de Stachytarpheta maximiliani Scham. (Verbenaceae) e seus visitantes florais

open access: yesRevista Brasileira de Entomologia, 2006
This study describes the reproductive system of Stachytarpheta maximiliani (Verbenaceae), including its floral biology, nectar and pollen availability and insect foraging patterns, identifying whose species act as pollinators. It was carried out in a Brazilian Atlantic rain forest site.

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 875-888, May 2026.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Bromelicolous Habit and Phoresy of Ostracoda in a Species of Treefrog From the Brazilian Cerrado

open access: yesAustral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Some plants develop phytotelmata, specialized structures that retain water and form small aquatic ecosystems harbouring diverse organisms. Bromeliads (Bromeliaceae) are classic examples, as their leaf axils provide suitable habitats for bacteria, algae, protozoa, invertebrates and vertebrates, including anurans.

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Estimating wild bee population size with validated distance sampling

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 469-483, May 2026.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

VPS13 has an important role in female germline development in Arabidopsis

open access: yesThe Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY The female germline precursor cell, known as the megaspore mother cell (MMC), differentiates and develops within the ovule through a complex genetic network, including post‐transcriptional and translational regulation mediated by miRNA. A key player in restricting MMC development to a single cell within the nucellus is the AUXIN RESPONSE FACTOR
