Taxonomic Novelties in Senna ser. Bacillares (Leguminosae, Cassieae)

open access: yesNordic Journal of Botany, Volume 2023, Issue 9, September 2023., 2023
Senna ser. Bacillares (Leguminosae, Cassieae) is the largest of the American Senna series, with approximately 50 species. Several taxa are still poorly known or with problematic delimitation. Based on extensive fieldwork and collection‐based research for our ongoing taxonomic studies on Senna ser. Bacillares, we identified two new species which we here

Promoting landscapes with a low zoonotic disease risk through forest restoration: The need for comprehensive guidelines

open access: yesJournal of Applied Ecology, Volume 60, Issue 8, Page 1510-1521, August 2023., 2023
Our results contribute to a more comprehensive forest restoration planning, comprising multiple ecosystem services and resulting in healthier landscapes for both people and nature. Our framework could be integrated into the post‐2020 global biodiversity framework targets.

Reassessment of generic boundaries in Neotropical Chrysophylloideae (Sapotaceae): Eleven reinstated genera and narrowed circumscriptions of Chrysophyllum and Pouteria

open access: yesTAXON, Volume 72, Issue 2, Page 307-359, April 2023., 2023
Abstract Classifications of the pantropical plant family Sapotaceae based solely on morphology have historically recognized between 125 and 53 genera. Phylogenetic analyses using molecular data have repeatedly demonstrated that broad concepts of two large genera belonging to subfamily Chrysophylloideae, Chrysophyllum and Pouteria, are untenable and ...

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 1, Page 49-69, January 2023., 2023
Abstract Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser ...

AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest

open access: yesEcology, Volume 103, Issue 9, September 2022., 2022
Abstract The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time

Interaction of precipitation with tree canopy increases nutrient input

open access: yesRevista Ambiente & Água, 2021
Given that atmospheric deposition is the first source of nutrient input into forest ecosystems, and that the precipitation partition serves as a nutritional source mainly when there is an interaction with the forest canopy, the objective of the present ...

Partial exclusion of precipitation: throughfall, stemflow and canopy interception in Eucalyptus plantations in southern Brazil

open access: yesRevista Ambiente & Água, 2021
Hydrological behavior in reforested watersheds is different from that under other forms of cover. The variation may be related to aspects intrinsic to species, planting density, physiological maturity, management system and climatic conditions ...
