Genetic patterns of myrceugenia correifolia, a rare species of fog-dependent forests of mediterranean Chile: is it a climatic relict?
(Frontiers Media SA, 2017)
Rare species frequently occur in areas with microclimatic conditions that are atypical for their regions, but that were more common in the past, and that probably have operated as climatic refugia for a long time. Myrceugenia ...
Late Quaternary climate change, relict populations and present-day refugia in the northern Atacama Desert: a case study from Quebrada La Higuera (18° S)
Aim In deserts, past climate change (and particularly past rainfall variability) plays a large role in explaining current plant species distributions. We ask which species were most and which were least affected by changes ...
Assessment of genetic differentiation among relict populations of calophyllum brasiliense camb. (calophyllaceae) from northeast Argentina
Calophyllum brasiliense is a tropical tree that grows exclusively in riparian forest and in almost permanently flooded areas. In Argentina two small populations located within riparian forest from Misiones and Corrientes ...
From relict saline wetlands to new ecosystems: Changes in bird assemblagesDe relictos de humedales salinos a nuevos ecosistemas: cambios en los ensambles de aves
(Sociedad Española de Ornitología, 2016-09)
En la ecorregión Pampa de América del Sur, la sustitución de los ecosistemas seminaturales por agroecosistemas es una de las principales causas de pérdida de biodiversidad. La intensificación agrícola ha llevado a la casi ...
