A novel bioenergy feedstock in Latin America? Cultivation potential of Acrocomia aculeate under current and future climate conditions
(Elsevier Ltd, 2016)
Plant oil is a key commodity in the global economy, particularly for food and bioenergy markets. However, current production practices often impair smallholder livelihoods, cause land use changes, and compete for food ...
Identifying barriers to effective management of widespread invasive alien trees: Prosopis species (mesquite) in South Africa as a case study.
(Elsevier Ltd, 2016)
Biological invasions are a major driver of ecological and social change globally. The negative effects of these invasions have led to the initiation of programs to manage these invasions across the world. Management aims ...
Seed characteristics in Cacataceae: Useful diagnostic features for screening species for invasiveness?
(Elsevier B.V., 2016)
Invasive alien species impose a wide range of negative impacts in invaded ecosystems. Management strategies aiming to minimize these impacts include measures to prevent the introduction of potentially invasive species, ...
Ant assemblages have darker and larger members in cold environments
(John Wiley & Sons Ltd, 2016)
Aim In ectotherms, the colour of an individual’s cuticle may have important thermoregulatory and protective consequences. In cool environments, ectotherms should be darker, to maximize heat gain, and larger, to minimize ...
Division of labour brings greater benefits to clones of Carpobrotus edulis in the non-native range: evidence for rapid adaptive evolution
(Creative Commons Attribution Licence (CC BY), 2016)
Why some species become invasive while others do not is a central research request in biological invasions. Clonality has been suggested as an attribute that could contribute to plant invasiveness. Division of labor is an ...
Invasive crayfish threaten Okavango Delta
(The Ecological Society of America, 2016)
Are native cyprinids of introduced salmonids stronger regulators of benthic invertebrates in South African headwater streams?
(Ecological Society of Australia, 2016)
The introduction of nonnative salmonids in the Southern Hemisphere generally leads to a reduction in invertebrate abundance and changes in assemblage composition. In the Cape Floristic Region of South Africa, introduced ...
Flammability of the keystone savannah bunchgrass Aristida stricta
Understanding the flammability of species in fire-prone or fire-dependent ecosystems is necessary for modeling and predicting ecosystem dynamics. Wiregrass (Aristida stricta syn. A. beyrichiana), a keystone perennial ...
Trophic overlap between fish and riparian spiders: potential impacts of an invasive fish on terrestrial consumers
(John Wiley & Sons Ltd., 2016)
Studies on resource sharing and partitioning generally consider species that occur in the same habitat. However, subsidies between linked habitats, such as streams and riparian zones, create potential for competition between ...
Starting a new population of Schwalbea Americana on a longleaf pine restoration site in South Carolina
(Southern Appalachian Botanical Society, 2016)
A new population of federally endangered Schwalbea americana (American chaffseed) was initiated at the state of South Carolina Department of Natural Resources Woods Bay Heritage Preserve, near Turbeville, South Carolina, ...
