Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Measuring and Modelling Hydrological Surface Connectivity

, 2012
Hydrological connectivity describes the internal linkages between runoff generation in upper parts of the catchment and the receiving water. It is quantified as the ratio of the runoff reaching the catchment’s outlet and the total internal runoff generation.

Assessment of ecosystem status in Mozambique and implications for environmental planning

Conservation Science and Practice, EarlyView.
We assess Mozambique's terrestrial ecosystems using the IUCN Red List of Ecosystems framework, showing that more than half of Mozambique's ecosystems are threatened, with impacts primarily concentrated in temperate subhumid grasslands and pyric tussock savannas.

Driver-pressure-impact and response-recovery chains in European rivers: observed and predicted effects on BQEs [PDF]

, 2011
The report presented in the following is part of the outcome of WISER’s river Workpackage WP5.1 and as such part of the module on aquatic ecosystem management and restoration. The ultimate goal of WP5.1 is to provide guidance on best practice restoration

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, EarlyView.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Regionalization and connectivity in the Gulf of Cádiz and Alborán Sea implication for marine spatial planning and coastal management [PDF]

, 2014
This work proposes a regionalization of marine waters south of the Iberian Peninsula based on empirical orthogonal functions and GIS analysis. The regions identified are consistent and correspond to hydrological mesoscale and macroscale structures well ...

Mountainous Floodplain Connectivity in Response to Hydrological Transitions

Water Resources Research
AbstractIn mountainous watersheds, floodplain sediments are typically characterized by gravel bed layers capped by an overlying soil unit that serves as a hotspot for biogeochemical reactivity. However, the influence of soil biogeochemistry on gravel bed underflow composition remains unclear, especially during hydrological transitions that alter the ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Evaluation of lake eutrophication under different hydrological connectivity conditions

Journal of Freshwater Ecology
Lake eutrophication has become a significant water environmental issue worldwide. In order to further explore the mechanism of hydrologic connectivity on lake eutrophication and effectively control it, this study selected Poyang Lake, Junshan Lake, Chi ...
