Water, energy and food supply security in the Gulf Cooperation Council (GCC) countries-A risk perspective
( MDPI AG , 2019 , Article Review)Supply systems for water, energy and food in the Gulf region are becoming highly interlinked. In the last decades, interdependence was evident in the increase of coproduction plants and the cross-sectoral resource use ... -
Consequences of marine barriers for genetic diversity of the coral-specialist yellowbar angelfish from the Northwestern Indian Ocean
( John Wiley and Sons Ltd , 2019 , Article)Ocean circulation, geological history, geographic distance, and seascape heterogeneity play an important role in phylogeography of coral‐dependent fishes. Here, we investigate potential genetic population structure within ... -
Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome
( Springer Verlag , 2019 , Article)Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current ... -
