Unraveling the drivers of community dissimilarity and species extinction in fragmented landscapes
(ECOLOGICAL SOC AMERWASHINGTON, 2012)
Communities in fragmented landscapes are often assumed to be structured by species extinction due to habitat loss, which has led to extensive use of the species-area relationship (SAR) in fragmentation studies. However, ...
Mixed Pyrus pyraster and Sorbus torminalis plantations including companion species enhance high-quality timber production
(Springer, 2020-08-26)
Wild pear (Pyrus pyraster (L.) Burgsd.) (P) and wild service tree (Sorbus torminalis (L.) Crantz) (S) are sporadic European tree species that are valued for their high-quality timber production. Although mixed plantations ...
An updated phylogeny of Deprea (Solanaceae) with a new species from Colombia: interspecific relationships, conservation assessment, and a key for Colombian species
(Cambridge University Press, 2018-10)
Deprea is a neotropical genus that comprises 51 species. Recent work based on molecular data has explored its monophyly and interspecific relationships, but the relationships amongst Deprea species were not entirely ...
Threats to seabirds: A global assessment
(Elsevier, 2019-09)
We present the first objective quantitative assessment of the threats to all 359 species of seabirds, identify the main challenges facing them, and outline priority actions for their conservation. We applied the standardised ...
What is the most suitable native bee species from the Neotropical region to be proposed as model-organism for toxicity tests during the larval phase?
(2020-10-01)
Currently, Brazil has a full framework for pesticide risk assessment established for Apis mellifera, based on the North American approach. However, the use of Apis mellifera as model-organism as a surrogate for Brazilian ...
Long-term monitoring of shrub species translocation in degraded Neotropical mountain grassland
(2018-01-01)
The introduction of plant species is a central topic in restoration ecology research. It is an effective technique to restore degraded ecosystems that present low resilience, such as the rupestrian grasslands. Once ...
Assessing impacts of ecosystem engineers on community organization: a general approach illustrated by effects of a high-Andean cushion plant
(BLACKWELL, 2006-11)
Comparative and integrative tools are of fundamental value in ecology for understanding outcomes of biological processes, and making generalizations and predictions. Although ecosystem engineering has been shown to play a ...
