A systematic review of the endangered genus Petrocerus Callaghan, 1979 (Lepidoptera: Riodinidae) reveals two new overlooked species

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Taxonomy is a fundamental discipline for biology, especially for the effective conservation of biodiversity. Here, we performed a review of Petrocerus Callaghan, 1979, an endangered and hitherto monotypic butterfly genus endemic to the Brazilian Atlantic Forest.

Historical Fragmentation in Atlantic Forest Explains the Diversification of a Clade of Mountaintop Bromeligenous Frogs (Leptodactylidae: Crossodactylodes)

open access: yesZoologica Scripta, Volume 54, Issue 6, Page 823-839, November 2025.
ABSTRACT The Atlantic Forest domain is a biodiversity hotspot with remarkable amphibian diversity, including over 700 species, 70% of which are endemic. Most of these endemic species have restricted geographic ranges, often confined to mountainous areas, as exemplified by the leptodactylid genus Crossodactylodes.

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

open access: yesNordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Plant and frugivore species characteristics drive frugivore contributions to seed dispersal effectiveness in a hyperdiverse community

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 238-253, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal by frugivores is a crucial step of the life cycle of most plants, influencing plant population and community dynamics. Although very important for most ecosystems, we are just beginning to understand which are the mechanisms driving frugivore‐mediated ...

Capybaras (Hydrochoerus hydrochaeris) Generate Grazing Lawns and Maintain Plant Diversity in Neotropical Savanna

open access: yesApplied Vegetation Science, Volume 28, Issue 1, January/March 2025.
We show that excluding native grazers from a South American grassy ecosystem leads to strong declines in plant species richness over an 18‐month period. Our results imply that severely defaunated South American ecosystems have retained plant taxa and functional trait complexes that can tolerate intense herbivory, identifying herbivore reintroductions ...

Enraizamento e aclimatização de brotos regenerados in vitro de bromélia imperial.

open access: yesOrnamental Horticulture, 2005
Uma das fases relevantes do processo de propagação de plantas in vitro é a indução de enraizamento e a aclimatização. A ineficiência desses processos ou falta de protocolos adequados pode inviabilizar todo o processo de micropropagação. Para a propagação
