Analysis of Historical and Projected Future Climate of Mali, West African Sahel by Birkel, S.D., Mayewski, P.A.

“…Atmospheric circulation across the North Atlantic is furthermore anomalously strong in CMIP5 due to an unrealistically steep pressure gradient between Azores and Iceland. These shortcomings undermine the fidelity and meaning of CMIP5 future rainfall projections across the western Sahel. …”

Clinal variation along precipitation gradients in Patagonian temperate forests: unravelling demographic and selection signatures in three Nothofagus spp. by Soliani, Carolina, Azpilicueta, Maria Marta, Arana, María Veronica, Marchelli, Paula

“…Past demographic changes and current selection pressures determine the genetic variation displayed by Nothofagus species along rainfall gradients. …”

Territorial dynamics of female wolverines by Aronsson, Malin

“…This is important from a Swedish management perspective, as the local density, and possibly predation pressure, might recover quickly after removal of territorial females, while the amount of economical compensation, based on number of wolverine reproductions, to reindeer herding districts for predation losses is reduced until next reproduction in the territory. …”

Torkning av vallfrö by Larsson, Lars

“…My tests have resulted in that i have been aware of the meaning the airflow and pressure has for the affectivity and drying costs. …”

Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey by Kymmell, David

“…I predicted that i) animals that are under high predation pressure will have a higher utilization of ‘save’ patches in the control sites where perceived risk is lower, and that ii) animals that experience no or low predation pressure will have a higher patch utilization in the burned areas where food availability is high. …”

The Effectiveness of Forest Conservation Policies and Programs by Börner, J., Schulz, D., Wunder, Sven, Pfaff, A.

“…Many interventions in our sample were implemented in “bullet-proof” contexts of low pressure on natural resources. This greatly limits their potential impacts and suggests the need to invest further not only in understanding but also in better aligning conservation with local and global development goals.…”

Evidence of balanced diversity at the chicken interleukin 4 receptor alpha chain locus by Downing, T., Lynn, D.J., Connel, S., Lloyd, A.T., Bhuiyan, A.K.F.H., Silva, P., Naqvi, A.N., Sanfo, R., Sow, R.S., Overseas Development Institute, Hanotte, Olivier H., O'Farrelly, C.O., Bradley, D.

“…In particular, because of pathogenic challenges it is expected that genes involved in the chicken immune system are subject to particularly strong adaptive pressure. Signatures of selection detected by inter-species comparison may then be investigated at the population level in global chicken populations to highlight potentially relevant functional polymorphisms.…”

Scoping study on participatory rangeland management (PRM) in Wajir by International Livestock Research Institute

“…A similar intervention has been successfully implemented through a pilot phase in Ethiopia where it was confirmed as an important concept in addressing rangeland degradation and other rangeland-based challenges where, over the years, rangelands have experienced pressure from a number of threats.…”

Nutrition and climate change: Shifting to sustainable healthy diets by Ruel, Marie T., Fanzo, Jessica

“…These are defined as nutritious, healthy (meaning they help prevent disease), safe, affordable, and culturally acceptable diets that support optimal nutrition and health and cause low environmental pressure and impact. The food systems tasked with producing these healthy diets are under significant stress due to environmental and natural resource constraints, as well as climate change. …”

Who will feed China in the 21st century?: Income growth and food demand and supply in China by Fukase, Emiko, Martin, Will

“…China's dietary shift from plant to animal‐based foods, induced by its income growth, is likely to impose considerable pressure on agricultural resources. China's demand for food on this measure appears consistent with global trends, while China is an out‐performer on the supply side, producing much more food than its income level and land endowment would predict. …”
