Evidence of low within-pair genetic relatedness in a relict population of Thorn-tailed Rayadito despite long-term isolation
(Wiley, 2022)
Investigating whether mating patterns are biased in relation to kinship in isolated populations can provide a better understanding of the occurrence of inbreeding avoidance mechanisms in wild populations. Here, we report ...
Assessment of genetic differentiation among relict populations of calophyllum brasiliense camb. (calophyllaceae) from northeast Argentina
(INNSPUB, 2014-12)
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 ...
Análise estrutural em relictos de cerrado no parque estadual do Guartelá, município de Tibagi, estado do Paraná, Brasil
(Universidade Federal de Santa Maria (UFSM), Centro Pesquisas Florestais, 2012-10-11)
This study was accomplished in existing Cerrado's relicts at State Park Guartelá, Tibagi, PR (24°39'10S and 50°15'25W), which represent one of the last extreme-meridional remanescents of this type of formation. Fifty plots ...
Effect of population combinations on the reproductive success and germination of seeds of Bromus auleticus (Poaceae)
(Wiley, 2015-03)
Bromus auleticus is known for its qualities as forage but its domestication has limitations relating to seed production technology and farm-scale seed propagation. The effect of different combinations of population on the ...
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier Gmbh, 2016-05)
Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ...
The Panama microplate, island studies and relictual species of Melipona (Melikerria) (Hymenoptera: Apidae: Meliponini)
(WILEY-BLACKWELLHOBOKEN, 2012)
The endemic stingless honey-making bee Melipona (Melikerria) insularissp.n. on Coiba and Rancheria Islands in Pacific Panama is described, together with the proposed sister species, M. ambigua sp.n. from northeast Colombia. ...
