Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
The study of Neotropical Apicotermitinae remains challenging due to the large number of undescribed taxa (Linnean shortfall) as well as the scarcity of distributional data (Wallacean shortfall). Despite recent efforts to reduce the first one, the second remains an even more significant challenge.
