Run to the Caves: Frog Refuges From Harsh Environments

open access: yesBiotropica, Volume 58, Issue 6, November 2026.
ABSTRACT The use of caves by primarily nontroglobiont organisms can be critical when the conditions of surrounding epigean habitats deteriorate as a result of synergic effects of climate changes and degradation of native vegetation cover. Under scenarios of unbalanced temperatures, high solar incidence, low humidity and reduced shelter availability in ...

Meckel‐gruber syndrome: About an evocative case in French Guiana—When ultrasound is insufficient for accurate diagnosis in a complex syndrome

open access: yesClinical Case Reports, 2020
In modern medicine, prenatal diagnosis can no longer be sufficient by ultrasound examination. The genetic technical progress and its contribution may remain a challenge in isolated sites with the consequences that this implies in perinatal health.

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.

Clinical Features and Management of Snakebite Envenoming in French Guiana

open access: yesToxins, 2020
The management of snakebite (SB) envenoming in French Guiana (FG) is based on symptomatic measures and antivenom (AV) administration (Antivipmyn Tri®; Instituto Bioclon—Mexico).

Phylogeny and updated infrageneric classification of Asemeia (Polygalaceae)

open access: yesTAXON, 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

Hydraulic function of medullary bundles in a tropical root climber

open access: yesAmerican Journal of Botany, Volume 113, Issue 9, September 2026.
Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

Toward Consistent Canopy Characterization From Low‐Cost UAV Imagery

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We show that UAV‐based crown segmentation can reliably characterize dominant canopy trees in a structurally complex tropical forest. Focusing on these key individuals improves the assessment of forest structure and supports ecological monitoring at multiple scales. ABSTRACT Monitoring tropical forest structure at landscape scale requires cost‐effective

Similar Habitat Gradients Across Native and Invasive Ranges Elicit Divergent Evolutionary Responses

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We used morphological and genetic data of native and invasive cane toads to demonstrate 1) body‐size differences between ecotypes, 2) whether native‐range ecotypes are genetically distinct and 3) whether patterns of selection for wetter versus drier environments in native and invasive populations were similar.

Distinct root‐associated fungal communities may account for the persistence of Podocarpus conifers in tropical forest

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract Podocarps (Podocarpaceae) are one of the few lineages of conifers found in closed canopy tropical forests. They typically have highly restricted distributions that are associated with nutrient‐poor sites. Unlike other tree species, the presence of distinct nodule‐like structures allows their roots to be easily distinguished from those of co ...

New Species and Distributional Synthesis of Apatelodidae (Lepidoptera: Bombycoidea) From the Brazilian Cerrado

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Brazilian Cerrado is a threatened biodiversity hotspot, but its Lepidoptera fauna remains poorly documented. Here, we provide the first comprehensive distributional synthesis of Apatelodidae in the Cerrado, integrating museum collections and verified citizen science records. We document 56 species, including five new taxa: Raoni hiprore sp.
