Variação genética em caracteres de crescimento em progênies de Dipteryx alata Vog
(2016-01-01)
The aim of this work was to estimate the genetic variation among and within Dipteryx alata progenies to propose a selective logging to establish a seedling seed orchard with variability and genetic quality. The progeny ...
Validation of microsatellite loci for Balfourodendron riedelianum through analysis of Mendelian inheritance, genetic linkage, and genotypic linkage disequilibrium
(Sciendo, 2019-01-01)
Balfourodendron riedelianum is a tropical tree endemic to the Atlantic Forest biome that is currently endangered due to forest fragmentation and extensive exploitation. Three populations of the species are conserved ex ...
Habitat fragmentation narrows the distribution of avian functional traits associated with seed dispersal in tropical forest
(2018-04-01)
Land-use change influences biodiversity in non-random ways, affecting some species and functional groups more than others, with potential implications for the loss or degradation of important ecological processes, such as ...
Intraspecific variation in seed germination and storage behaviour of Cordia tree species of subtropical montane forests of Argentina: Implications for ex situ conservation
(Elsevier, 2019-07)
Cordia americana, C. saccelia and C. trichotoma are native trees of the subtropical Andean forests of Argentina. Due to their high value as a wood source, these species are under threat from the over-exploitation of their ...
Bertholletia excelsa SEEDS IN THE CERRADO-AMAZON TRANSITION REGION: MORPHOMETRY, COLORIMETRY, VIABILITY AND GERMINATION
(Universidade Federal de Mato Grosso, 2023)
Leaf litter is essential for seed survival of the endemic endangered tree pouteria splendens (Sapotaceae) from central Chile
(Copernicus Gesellschaft MBH, 2018)
Pouteria splendens (A. DC.) Kuntze, the Chilean lucumo, is an endemic tree and the only member of the Sapotaceae family in Chile. It is considered an endangered species as a consequence of its restricted distribution and ...
Effects of forest fragmentation, anthropogenic edges and fruit colour on the consumption of ornithocoric fruits
(Elsevier B.V., 2003-06-01)
We investigated effects of fruit colour (red, black or white), habitat (anthropogenic edges and forest interior) and fragment size on the removal of artificial fruits in semideciduous forests in south-east Brazil. Eight ...
