Unveiling Shell Geometry: Morphometric Differences Between the Invasive Mussel Perna viridis and the Native Perna perna

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Perna viridis is an invasive mussel species recently introduced to the southeastern coast of Brazil, where it coexists with the native Perna perna. Morphological similarity between these species, particularly in early life stages, has led to frequent misidentifications, compromising ecological assessments and management efforts.

Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation

Secondary wind dispersal enhances long-distance dispersal of an invasive species in urban road corridors [PDF]

open access: yes, 2011
Roads contribute to habitat fragmentation and function as dispersal barriers for many organisms. At the same time many nonnative plant species are associated with road systems, a relationship that has been explained by the availability of disturbed ...
