Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1805-1816, September 2026.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

Carbon Stocks in Sugarcane Biomass and Their Implications on Land Use Change CO2 Balance in Brazil

open access: yesGCB Bioenergy, Volume 18, Issue 8, August 2026.
This paper develops a regionalized carbon stock factor for sugarcane biomass in Brazil, showing that sugarcane cultivation can lead to net carbon removal in most municipalities. The findings improve greenhouse gas inventories and support bioenergy policies by providing more accurate, spatially resolved estimates for land use change emissions.

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 9, July 2026.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Forecasting climate change impacts on neotropical Myotis: Insights from ecological niche models for conservation strategies

open access: yesEcology and Evolution
Myotis originated during the Oligocene in Eurasia and has become one of the most diverse bat genera, with over 140 species. In the case of neotropical Myotis, there is a high degree of phenotypic conservatism. This means that the taxonomic and geographic

The role of environmental and life history traits in larval growth and settlement success of the blenny Ophioblennius trinitatis

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Reef fish have complex life cycles where pelagic larval survival and recruitment are linked to environmental and early life history traits (ELHTs). We combine light traps and otolith microstructure analysis to examine how environmental variables and ELHTs drive larval growth and settlement in the endemic Ophioblennius trinitatis.

New records of the flower fly Lejops barbiellinii (Ceresa, 1934) (Diptera, Syrphidae) in the Atlantic Forest: integrating collection and citizen science data

open access: yesEntomological Communications
Citizen science provides valuable data on species diversity worldwide. In this note, we discuss how a scientist's opportunistic observations of biodiversity, recorded on a citizen science platform, have enriched our understanding of the geographic ...
