Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Comparação entre Métodos de Mapeamento Topográfico de Cavernas Ferríferas: Estudo de Caso na Amazônia Brasileira

Revista Brasileira de Cartografia
O cálculo dos parâmetros espeleométricos (projeção horizontal, desnível, área e volume) em meio ao mapeamento topográfico de cavernas é um requisito amparado por lei para a definição do grau da relevância de cavidades no Brasil.

Soil organic carbon data comparison after 85 years and new 13C/12C compositions: The case study of the Ferrara province (Northeastern Italy)

Journal of Environmental Quality, Volume 53, Issue 2, Page 147-161, March/April 2024.
Abstract The main causes of soil organic matter (SOM) loss are land use (e.g., conventional agriculture) and land‐use change (e.g., conversion of wetlands into croplands). Before World War II and until 1960s, the Ferrara province in the Emilia‐Romagna region (Northeast Italy) enlarged its agricultural production area through drainage of wetlands. After

Incomplete recovery of tree community composition and rare species after 120 years of tropical forest succession in Panama

Biotropica, Volume 56, Issue 1, Page 36-49, January 2024.
The late stages of tropical forest succession are understudied. Here we analyze tree community recovery over one of the oldest chronosequences in the Neotropics and find recovery of species diversity and forest structure, within 40 and 90 years respectively, but species community compositional recovery is slow, with one plot converging on old‐growth ...
