Cambios estacionales en los ensambles de aves en un ecotono bosque-estepa del norte de Patagonia [PDF]

, 2018
Estudiamos las variaciones estacionales en una comunidad de aves que habitan el ecotono bosque-estepa del norte de Patagonia. Analizamos los cambios en la riqueza de especies, la composición de especies y la abundancia total, y a nivel de las especies ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Rodent-Mediated Seed Dispersal Shapes Species Composition and Recruitment Dynamics in Ecotones

Frontiers in Plant Science, 2018
Ecotones are considered unique environments, and the concepts of edge effects and ecotonal species have been applied widely. Our understanding of the mechanisms that underlie population and community responses to edge effects has been advanced by recent ...

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, EarlyView.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Carbon fluxes in a mature deciduous forest under elevated CO₂ [PDF]

, 2010
This PhD thesis addressed several major aspects of the carbon (C) cycle in a c. 100-year-old, mixed deciduous forest under elevated CO₂ with an emphasis on below-ground processes.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Relationship between food quality and body size of common vole in different habitats

Pest Management Science, EarlyView.
The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

Intra-annual variations of plant and soil biota community in a grassland under nitrogen addition and mowing

Geoderma
Diversity and composition of plants and soil biota are critical determinants of fundamental ecosystem functions. Although the compositional responses of organisms across trophic levels to global change drivers and ecosystem management strategies have ...
