Journal of Fish Biology, EarlyView.Abstract A new species of Characidium is described from the Iguaçu National Park, Brazil. The new species can be diagnosed from the congeners by the absence of conspicuous vertical bars, blotches and spots along the sides of the body, the presence of a scaled isthmus and adipose fin, a series of scales below lateral line and the presence of a thin dark

Host‐Cleptoparasite Biogeographical Congruence Through Time: The Case of Cuckoo Oil Bees
Journal of Biogeography, Volume 52, Issue 5, May 2025.ABSTRACT Aim Insect brood parasites (i.e., cleptoparasites), like cuckoo bees, typically attack hosts within specific lineages, but seem to be less constrained by the biogeographical movements of their hosts compared to obligate parasites. Cuckoo bees depend on stable host populations, being particularly sensitive to environmental changes and thus ...

Insect Conservation and Diversity, Volume 18, Issue 2, Page 275-284, March 2025.The structural components of the Cerrado are essential for conserving insect species richness, as conserved Cerrado habitats support higher insect species richness compared to exotic pastures Insect abundance is similar between conserved Cerrado and exotic pastures; therefore, synanthropic species may obscure the decline of sensitive insect populations

Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity
Functional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees
Global Change Biology, Volume 31, Issue 1, January 2025.We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).

Water‐Dispersible BODIPY Multifunctionalized Silicon Oxide Nanoparticles for Glutathione Sensing
Particle &Particle Systems Characterization, Volume 41, Issue 10, October 2024.A boron‐dipyrromethene (BODIPY)‐based probe (PB) is synthesized, incorporating a fluorescent core, chlorine substituents for glutathione (GSH) reaction, and a linking moiety for conjugation to silicon oxide nanoparticles (SONPs). Characterization confirms successful functionalization and water‐dispersibility of SONPs. GSH sensing is evaluated for probe
