How are endemic and widely distributed bromeliads responding to warming temperatures? A case study in a Brazilian hotspot
(Elsevier B.V., 2018-01-01)
The increase in mean global temperature is causing extensive changes in ecosystems. However, little is yet known about the heat tolerance of neotropical plant species. Here, we investigate heat tolerance variation in both ...
Megalops atlanticus Valenciennes, 1847 (Elopiformes, Megalopidae): New records for the state of São Paulo, with comments on its occurrence in the southeastern coast of Brazil, Southwest Atlantic
(2018-03-16)
New records of Megalops atlanticus Valenciennes, 1847 in the state of São Paulo, southeastern Brazil, are reported from recreational catches carried out in February 2017. Data collected is the first occurrence of this ...
The functional biogeography of species: Biogeographical species roles of birds in Wallacea and the West Indies
(2013-10-01)
Biogeographical systems can be analyzed as networks of species and geographical units. Within such a biogeographical network, individual species may differ fundamentally in their linkage pattern, and therefore hold different ...

Species roles in plant–pollinator communities are conserved across native and alien ranges
(2016-08-01)
Aim: Alien species alter interaction networks by disrupting existing interactions, for example between plants and pollinators, and by engaging in new interactions. Predicting the effects of an incoming invader can be ...
The use of biosphere reserves by a wide-ranging avian scavenger indicates its significant potential for conservation
(Cambridge University Press, 2019-09-13)
The framing of environmental conservation has been changing, mainly towards a reconciliation between human needs and nature conservation. A major challenge of biosphere reserves (BRs) is the integration of biodiversity ...
Geographic Variation among Closely Related, Highly Variable Species with a Wide Distribution Range: the South Andean-Patagonian Nassauvia subgenus Strongyloma (Asteraceae, Nassauvieae)
(American Society of Plant Taxonomists, 2014-03)
Morphological variation among the five species of Nassauvia subgenus Strongyloma was assessed through statistical analyses of morphometric traits in populations throughout the southern Andean-Patagonian region. Uni- and ...
Produção de sementes e comportamento germinativo de Tibouchina clavata (Pers.) Wurdack. (Melastomataceae)
(2012-06-01)
In the process of riverine forest restoration, increasing emphasis has been given to the study of herbaceous and shrub species. However, for many of these we still lack basic knowledge, such as reproduction biology. ...
