Edge effect on post-dispersal artificial seed predation in the southeastern Amazonia, Brazil

Brazilian Journal of Biology
This paper evaluates the post-dispersal artificial seed predation rates in two areas of the southeastern Amazon forest-savanna boundary, central Brazil. We conducted the survey in a disturbance regime controlled research site to verify if exists an edge ...

Evidence of the trade-off between starvation and predation risks in ducks [PDF]

, 2011
The theory of trade-off between starvation and predation risks predicts a decrease in body mass in order to improve flight performance when facing high predation risk.

Landscape drivers of scaled quail occurrence across a broad spatiotemporal scale: implications for habitat management

The Journal of Wildlife Management, EarlyView.
Combining large‐scale avian surveys with remote sensing products revealed landscape variables that likely limit scaled quail occurrence at the ecoregion scale in Texas. Promoting management practices that address ecoregion‐specific limiting factors may be key to averting further declines.

Microhabitat structure modulates seed fate outcomes through differential effects on native and exotic rodent interactions in an endangered palm species

Basic and Applied Ecology
Microhabitat structure plays a critical role in rodent behavior and seed resource use, influencing plant population dynamics through shifts between positive and negative interaction outcomes.

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Ground beetles (Carabidae) as seed predators

European Journal of Entomology, 2003
The consumption and preferences of polyphagous ground beetles (Coleoptera: Carabidae) for the seeds of herbaceous plants was determined. The seeds were stuck into plasticine in small tin trays and exposed to beetle predation on surface of the ground.

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.
