Phylogeny and updated infrageneric classification of Asemeia (Polygalaceae)

TAXON, Volume 75, Issue 5, October 2026.
Abstract The family Polygalaceae comprises approximately 1200 species in 30 genera worldwide. Among the four tribes within the family, tribe Polygaleae is characterized by unique flower structures resembling those of Leguminosae‐Papilionoideae. Asemeia is a genus within tribe Polygaleae, consisting of 36 species and 1 variety distributed throughout the

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

Functional Ecology, Volume 40, Issue 10, Page 3048-3062, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.

Cultivo de matrinxã Brycon orthotaenia (Günther, 1864) em tanques-rede, em diferentes densidades de estocagem = Matrinxã Brycon orthotaenia rearing in floating cage in different stocking densities

Acta Scientiarum: Biological Sciences, 2010
O presente experimento avaliou o desempenho e sobrevivência de juvenis de matrinxã Brycon orthotaenia cultivados em tanques-rede de 4 m3, por 197 dias, em três densidades de estocagem: 20, 40 e 60 peixes m-3. Foram utilizados exemplares com 19,9 ± 0,3 cm

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, Volume 95, Issue 10, Page 1903-1918, October 2026.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Filtered, yet not homogenised: Urbanisation does not lead to cross‐city convergence in Mexican urban bird communities

Journal of Animal Ecology, Volume 95, Issue 10, Page 1933-1943, October 2026.
Urbanisation simplifies bird communities, but does not necessarily make urban avifaunas alike. Across three biogeographically distinct Mexican cities, urban bird assemblages remained regionally distinct despite strong local filtering. These results challenge assumptions of urban‐driven homogenisation and emphasise the dominant role of regional species ...

Five new species of Hemibrycon (Characiformes: Characidae) from the Río Magdalena basin, Colombia

Revista de Biología Tropical, 2010
Five new fish species of the genus Hemibrycon are described from the Río Magdalena basin, Colombia, using morphometric, meristic and osteological characters. Hemibrycon paez (n=40) differs in number of lateral line scales (39 to 42 vs.

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, Volume 95, Issue 10, Page 2050-2062, October 2026.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

Key practices for ethical research during scientific expeditions

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
In many cases, expeditionary practices undermined local knowledge and expertise. This perspective advocates for a shift from parachute science towards a collaborative research approach. We reflect on and suggest best practices during scientific expeditions within research teams and in the team's interactions with different communities.

Population genetic structure revealed by a school of the freshwatermigratory fish, Brycon hilarii Estructura genética poblacional revelada por un cardumen del pez migratorio de agua dulce, Brycon hilarii

Latin American Journal of Aquatic Research, 2012
It is believed that different genetic populations of migratory fishes can co-exist in a single hydrographic system. Although different populations may occupy and explore the river together, they segregate during the spawning season and consequently the ...
