Zoologica Scripta, EarlyView.ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes
Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Long‐term trends in parasite diversity and infection levels: approaches and patterns
Biological Reviews, Volume 101, Issue 3, Page 1120-1142, June 2026.ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

Feddes Repertorium, Volume 137, Issue 2, June 2026.ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

A New Species of Myriopus (Heliotropiaceae) From Brazil
Feddes Repertorium, Volume 137, Issue 2, June 2026.ABSTRACT A new species of Myriopus (Heliotropiaceae), Myriopus chrysocalyx J.I.M. Melo & L.G. Sá, hitherto recorded for the Brazilian Northeastern is described and illustrated. Myriopus chrysocalyx can be readily recognized by its branches strigose to villous, and, mainly, for presenting leaf blade chartaceous to subfleshy, congested inflorescences, a ...
