Clarifying the Labrisomus Conundrum: Deep Divergence, Cryptic Lineages, and a Genetic Melting Pot in the Atlantic Ocean (Teleostei, Labrisomidae)

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluate the phylogenetic relationships and taxonomic validity of Atlantic species of Labrisomus, identifying the lineages currently assigned to L. nuchipinnis, and assessing the role of biogeographic barriers in shaping the evolutionary history and geographic distribution of the genus. Location Atlantic Ocean.

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120

Gastrointestinal Parasites in Free‐Ranging Saguinus ursulus From the Eastern Brazilian Amazon: First Report of Prosthenorchis sp.

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Enteroparasites were investigated in free‐ranging Saguinus ursulus from the eastern Brazilian Amazon. Parasites were detected in 76.5% (13/17) of capture events, with Prosthenorchis sp. most frequently detected (58.8%; 10/17). Animals showed good body condition and no clinical abnormalities.

Amazon river prawn larvae incorporate astaxanthin in response to dietary supplementation with Bixa orellana

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract This study evaluated the effects of dietary bixin, a carotenoid from Bixa orellana, on larval development, post‐larval performance, and carotenoid deposition in Macrobrachium amazonicum under controlled conditions. Larvae were reared in a recirculating aquaculture system with a moving bed biofilm reactor (MBBR) and fed Artemia nauplii and an ...

Cooperative and Non‐Cooperative Solutions in a Dynamic Model of Forest Management

Natural Resource Modeling, Volume 39, Issue 3, August 2026.
ABSTRACT This study develops a deterministic finite‐horizon bioeconomic control model linking forest biomass, biodiversity, cumulative harvesting pressure, and disturbance‐motivated expected biodiversity losses. Biodiversity is modeled as a productive state variable that feeds back into biomass growth, while cumulative harvesting pressure records the ...
