Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

Ecography, EarlyView.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

The environmental resource curse hypothesis: the forest case [PDF]

The resource curse hypothesis relies on the resource-rich countries tendency to grow slower than resource-poor countries. Focusing on forest issues, this paper extends the resource curse hypothesis to environmental degradation: how do forest endowment ...

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Think globally and act locally: Assessing the environmental impacts of the Nigerian threatened native trees project

Societal Impacts
The environmental and socio-economic impacts of the Nigerian Threatened Native Trees Project are presented. This project conducted propagation trials and developed a freely downloadable online Manual of Tree Propagation (MTP) for 55 native tree species ...

Geodiversity is an inseparable but underutilized aspect of ecological connectivity assessments under climate change

Ecography, EarlyView.
Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

Fragmentation Increases Impact of Wind Disturbance on Forest Structure and Carbon Stocks in a Western Amazonian Landscape [PDF]

Tropical second-growth forests could help mitigate climate change, but the degree to which their carbon potential is achieved will depend on exposure to disturbance.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

MODELING ECOLOGICAL CONSTRAINTS ON TROPICAL FOREST MANAGEMENT: COMMENT [PDF]

We comment on four aspects of Albers' [1] model of ecological constraints on tropical forest management. Albers structures her model in a highly asymmetric manner, with strong, uniform biases against development and in favor of preservation.

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

Ecography, EarlyView.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Certification of tropical forests: from impact assessment to political economy? [PDF]

, 2018
Certification has not reduced deforestation in tropical countries. However, improving the management of productive forests would indirectly contribute to preventing deforestation through sustainable forest-oriented development of a territory.
