Morphometric differences between two exotic invasive freshwater caridean species (genus Macrobrachium)
(2018-01-01)
The prawns Macrobrachium amazonicum and Macrobrachium jelskii, have been introduced in the southeastern Brazilian region. Thus, it becomes necessary knowing the reproductive aspects of these invasive species. This study ...
Joint species movement modeling: how do traits influence movements?
(2019-04-01)
Joint species distribution modeling has enabled researchers to move from species-level to community-level analyses, leading to statistically more efficient and ecologically more informative use of data. Here, we propose ...
Habitat heterogeneity drives bird species richness, nestedness and habitat selection by individual species in fluvial wetlands of the Paraná River, Argentina
(Wiley Blackwell Publishing, Inc, 2016-11)
We assessed the relationship between habitat heterogeneity and bird species richness and composition within wetlands of the floodplain of the Middle Paraná River, Argentina. Given the high habitat heterogeneity in these ...
Photochemistry and hydric responses of congeneric Croton species at restoration sites under dry season: implications for species selection
(2019-06-15)
The success of the ecological restoration depends on the appropriate determination of species for implantation in restoration areas. The use of physiological performance as a criterion may help in the selection of species ...
A comparison of temporal turnover of species from benthic cnidarian assemblages in tropical and subtropical harbours
(Oxford, 2015)
An important component of species diversity which has recently received significant attention is the change in species composition across space, or beta diversity. Temporal turnover of species is an equally important ...
Evaluation of survey methods for sampling anuran species richness in the neotropics.
(2010-12-01)
Species richness is central to ecological theory, with practical applications in conservation, environmental management and monitoring. Several techniques are available for measuring species richness and composition of ...
ON THE WINGS OF IDENTIFICATION: USE OF WINGS MORPHOMETRY IN Melipona SPECIES
(Interciencia, 2016-09-01)
The Melipona genus has the highest bee species richness of in Brazil, and the group needs taxonomic revision. Due to the difficulties in identifying bee groups, methods to facilitate and improve the identification of species ...
Cytogenetic studies on the subfamily Hypoptopomatinae (Pisces, Siluriformes, Loricariidae).lll. analysis of seven species
(1994-01-01)
Cytogenetic studies carried out on nine species belonging to five genera of the subfamily Hypoptopomatinae showed that this group has a relatively constant diploid number, 2n =54, with only one species having 2n = 72 ...
Evaluation of hyperspectral multitemporal information to improve tree species identification in the highly diverse atlantic forest
(2020-01-01)
The monitoring of forest resources is crucial for their sustainable management, and tree species identification is one of the fundamental tasks in this process. Unmanned aerial vehicles (UAVs) and miniaturized lightweight ...
Effects of species turnover on reserve site selection in a fragmented landscape
(SPRINGER, 2011)
Changes in species composition is an important process in many ecosystems but rarely considered in systematic reserve site selection. To test the influence of temporal variability in species composition on the establishment ...
