Past cover modulates the intense and spatially structured natural regeneration of woody vegetation in a pastureland
(2020-03-01)
Vegetation natural regeneration after agricultural abandonment is changing the landscape patterns in many areas worldwide. However, the expansion rate, spatio-temporal dynamics, and the role of past vegetation cover in ...
Stand development stages and recruitment patterns influence fine-scale spatial genetic structure in two Patagonian Nothofagus species
(Springer, 2022-05)
Key message: Nothofagus alpina (Poepp. et Endl.) Oerst. and Nothofagus obliqua (Mirb.) Oerst forests have strong fine-scale spatial genetic structures. The intensity of genetic structure patterns differed according to ...
Contrasting effects of sampling scale on insect herbivores distribution in response to canopy structure
(Universidad de Costa Rica, 2013)
Scale-dependent patterns of metacommunity structuring in aquatic organisms across floodplain systems
(2021-04-01)
Aim: Evaluating how groups of organisms vary in dispersal capability and how environmental, spatial and temporal signals vary across multiple scales is critical to elucidating metacommunity theory. We examined whether the ...
Spatial distribution of cephalopod paralarvae in San José Gulf (Northern Patagonia, Argentina): The role of tidal circulation in larval dispersal
(Elsevier, 2013-07)
tThe spatial distribution of cephalopod paralarvae was studied in waters of San José Gulf (SJG), a shallowbasin connected to a larger gulf (San Matías, SMG) through a narrow mouth located on its northwest-ern margin. The ...
Fine-scale spatial genetic structure analysis in two Argentine populations of Prosopis alba (Mimosoideae) with different levels of ecological disturbance
(Springer, 2016-06)
Spatial genetic structure (SGS) in plants is primarily determined by the interaction between pollen and seed dispersal, but it is strongly affected by both evolutionary and ecological processes. SGS studies in forest species ...
Staying close: Short local dispersal distances on a managed forest of two Patagonian Nothofagus species
(Oxford University Press, 2020-05)
Understanding the impact of management on the dispersal potential of forest tree species is pivotal in the context of global change, given the implications of gene flow on species evolution. We aimed to determine the effect ...
Effect of fine-scale spatial variation of soil nitrogen on the performance of the sexes of Poa ligularis in patchy ecosystems of northern Patagonia
(University of Chicago Press, 2002-06)
In patchy environments of arid Patagonia, males of the dioecious grass Poa ligularis dominate in N-poor microsites, while females are more common in N-rich microsites. In order to explore functional differences related to ...
Tree species composition and environmental relationships in a Neotropical swamp forest in Southeastern Brazil
(2008-12-01)
We examined the relationships between topography, soil properties and tree species composition in a Neotropical swamp forest in southeastern Brazil. Plots were sampled in the forest, encompassing three different soil ground ...
