Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

Fisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

Plant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

Ecological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Avaliação do risco de extinção do veado-campeiro Ozotoceros bezoarticus Linnaeus, 1758, no Brasil

Biodiversidade Brasileira, 2012
O estado de conservação no Brasil, das duas subespécies do veado-campeiro, Ozotoceros bezoarticus (Linnaeus, 1758), que ocorrem no país, foi avaliado de acordo com os critérios da IUCN (2001), com base nos dados disponíveis até 2010.

Synopsis of the Genera of Eucanthini Nikolajev, 2002 (Coleoptera: Geotrupidae), With Two New Genera From Australia and South America

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Here, we review the generic classification of Eucanthini, resulting in the redefinition of Eucanthus Westwood, 1848 and erection of two new genera. Under this new framework, Eucanthus is restricted to six North American species, while two monotypic genera are described from the Southern Hemisphere: Antoniocanthus gen. nov.

Typification of Caesalpinia desertorum and its nomenclatural priority over Caesalpinia bracteosa (Leguminosae, Caesalpinioideae)

TAXON, Volume 75, Issue 5, October 2026.
Abstract Caesalpinia desertorum was not properly typified and has long remained of uncertain taxonomic position. A critical reassessment of the original material cited in the protologue, together with historical herbarium collections and associated literature, allows us to designate a lectotype and clarify its identity.

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

Acta Zoologica, Volume 107, Issue 4, Page 460-469, October 2026.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

Fisheries Management and Ecology, Volume 33, Issue 5, Page 933-948, October 2026.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, Volume 168, Issue 4, Page 1210-1229, October 2026.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.
