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

Journal of Fish Biology, EarlyView.
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 ...

Amazonian amphibians: diversity, spatial distribution patterns, conservation and sampling deficits [PDF]

Biodiversity Data Journal
The Amazon biome is home to the largest tropical forest on the planet and has the greatest global biodiversity on Earth. Despite this, several less charismatic taxonomic groups, such as amphibians, lack comprehensive studies on their species richness and

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.

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, Volume 252, Issue 1, Page 36-48, October 2026.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Plant-Pollinator and Plant-Florivore Interactions in Two Savanna Species of Malpighiaceae

Plants
Plant density influences interspecific interactions such as pollination and herbivory. In denser populations, pollinators find flowers more easily, increasing reproductive success and population growth. However, the same floral attractiveness also favors

Sclerophyllous structural and chemical traits of mite‐induced galls on Crinodendron patagua (Elaeocarpaceae) leaves

Plant Biology, Volume 28, Issue 6, Page 2039-2053, October 2026.
Eriophyid mites reprogram the structural and biochemical traits of sclerophyllous leaves in Crinodendron patagua, promoting the formation of nutrient‐rich and protective gall tissues. Abstract Sclerophyllous plants present a suite of traits, including small, leathery leaves with thick cuticles, dense trichomes and sclerified tissues, which are often ...
