A biogeografia e o biomonitoramento ambiental

Revista Espaço e Geografia, 2023
O biomonitoramento se constitui enquanto uma ferramenta utilizada para avaliar a qualidade dos ambientes. São considerados indicadores ambientais ou, bioindicadores, espécies e conjuntos de espécies com capacidade de reagir e registar distúrbios ou alterações no ambiente ao qual pertencem.

La Biogeografía histórica y la interpretación de la biodiversidad: algunas reflexiones metodológicas [PDF]

, 1995
Malgrat que la idea de biodiversitat es fonamentalment un concepte, ecològic, es prou evident que la complexitat biològica és el resultat del procés d'evolució orgànic en l'espai i en el temps.

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 ...

Ecological and Spatial Drivers of Diversification and Hybridization in Phalacrocarpum (Anthemideae, Asteraceae)

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aims Range shifts and niche differentiation can promote hybridization and homoploid hybrid speciation by bringing different lineages into contact and afterwards facilitating their reproductive isolation. The Iberian endemic angiosperm genus Phalacrocarpum is a suitable model to explore these processes.

Habitat Amount Shapes Ant Diversity in the Central Amazon

Biotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...
