Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

open access: yesMedical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

open access: yesPlant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

Tropical savanna restoration: topsoil removal and direct‐seeding promote a biodiverse and invasion‐resistant community

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Open ecosystems, such as native grasslands and savannas, cover vast tropical areas and sustain multiple ecosystem services. However, they face intense degradation due to conversion into pastures with exotic grasses that invade natural ecosystems.

Fish Assemblages in an Urbanized Neotropical Basin: Influence of Environmental Factors Across Dry and Rainy Periods

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT This study investigated the effects of season and environmental disturbances on fish communities in neotropical rivers of the Sorocaba basin, a Sub‐Basin of the Paraná River in Southeast Brazil, based on sampling 1196 individuals from 49 species, including two non‐native and one threatened with extinction.

Uncovering the Diversity of Mesostoinae (Hymenoptera: Braconidae): A Glimpse Into the Australian Fauna Through a Study of Kangaroo Island

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT The Mesostoinae are a poorly understood braconid subfamily with unresolved morphological challenges and a complex taxonomic history. This study provides insight into the biodiversity of this subfamily on Kangaroo Island (KI), South Australia.

On the origin of present Neotropical biodiversity

open access: yes
The evolutionary origin of extant species has been largely debated. The controversy is especially vivid in the Neotropics, one of the more biodiverse regions of the world. One hypothesis is that Neotropical species emerged primarily during the Quaternary (the last ~2 million years), favored by the alternating glacial/interglacial climates.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
