Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

Austral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Gross Anatomy and Approach to the Humerus and Femur in the White‐Eared Opossum (Didelphis albiventris)

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The white‐eared opossum (Didelphis albiventris) is a Neotropical marsupial that readily adapts to urban environments. Due to its presence in anthropogenic habitats, this species is frequently exposed to vehicle collisions and dog attacks. Such trauma often results in long bone fractures, with humeral and femoral fractures being common in ...

Spermatogenesis and Morphology of the Male Reproductive Tract of the Turtle Kinosternon scorpioides

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The scorpion mud turtle (Kinosternon scorpioides), a freshwater chelonian widely distributed in South and Central America, presents gaps in the microscopic and ultrastructural characterisation of its male reproductive system. This study provides a comprehensive characterisation of the testes, epididymides, and deferent ducts of adult males ...

Grass Communities Differ Floristically Under Different Dominant Trees in Savannas in Thailand and Cambodia

Biotropica, Volume 58, Issue 2, March 2026.
In total, we recorded 160 unique grass species across four savanna ecosystems dominated by different tree genera. These savannas support distinct grassy assemblages, but common grasses are often shared between ecosystems. ABSTRACT Southeast Asian savannas are some of the least studied ecosystems, with understanding of their function and resilience ...

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.

“Women Enlace”: Interweaving Women to Make Collective Action Possible

Gender, Work &Organization, Volume 33, Issue 2, Page 554-571, March 2026.
ABSTRACT This study engages with the contemporary debate on women's collective action through the lens of commons governance. Drawing on the theory of collective action in the management of common‐pool resources (CPRs) and on feminist ethnography with a group of rural extractivist women in the Cerrado—a vast tropical savanna biome in Brazil's Central ...

PhotoBiology Station for Plant–Light Interactions Studies in Field Conditions

Journal of Agronomy and Crop Science, Volume 212, Issue 2, March 2026.
ABSTRACT Light is a primary source of energy for photosynthesis and a fundamental signal that governs plant morphology and growth dynamics through well‐orchestrated signalling pathways. In field conditions, light intensity and quality, as well as other variables, constantly change throughout the day.

Regions of Climatic Stability for Neotropical Primates

Mammal Review, Volume 56, Issue 1, March 2026.
Spatial distribution of climatic stability, endemism, and model uncertainty for Neotropical primates. The left panel depicts projected climatic stability (warm colours = higher proportion of species with persistent climatic suitability; cool colours = lower stability). The upper‐right panel shows endemism (warm colours = higher concentration of endemic

The Changing Landscape of Root‐Knot Nematodes in Brazilian Soybean Fields: Shifting Prevalence of Meloidogyne arenaria, M. incognita and M. javanica and the Occurrence of an Emerging Species, M. enterolobii

Plant Pathology, Volume 75, Issue 2, March–April 2026.
An integrative biochemical and molecular survey of 344 soybean fields across Brazil revealed shifts in Meloidogyne species composition, high co‐occurrence rates, and the first report of M. enterolobii in commercial soybean fields, highlighting its geographic expansion and the need for improved nematode management strategies.

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

Zoologica Scripta, Volume 55, Issue 2, Page 220-231, March 2026.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...
