Legacy effects of an invasive legume more strongly impact bacterial than plant communities in a Mediterranean-type ecosystem.

The impacts of invasive plants on ecosystem processes and functions may persist as "legacy effects" after their removal. Understanding these effects on native plant-soil interactions is critical for guiding ecological restoration efforts. This study examines the legacy effects of the invasive legume Acacia saligna (Labill.

Realised rather than fundamental thermal niches predict site occupancy: Implications for climate change forecasting.

Thermal performance traits are regularly used to make forecasts of the responses of ectotherms to anthropogenic environmental change, but such forecasts do not always differentiate between fundamental and realised thermal niches. Here we determine the relative extents to which variation in the fundamental and realised thermal niches accounts for current variation in species abundance and occupancy and assess the effects of niche-choice on future-climate response estimations. We investigated microclimate and macroclimate temperatures alongside abundance, occupancy, critical thermal limits and foraging activity of 52 ant species (accounting for >95% individuals collected) from a regional assemblage from across the Western Cape Province, South Africa, between 2003 and 2014.

An assessment of the effectiveness of a long-term ecosystem restoration project in a fynbos shrubland catchment in South Africa.

The long-term effectiveness of ecological restoration projects is seldom reported in the scientific literature. This paper reports on the outcomes of ecosystem restoration following the clearing of alien Pinus plantations and associated alien plant invasions over 13 years from an 8000 ha mountain catchment in the Western Cape Province, South Africa. We examined the goals, methods and costs of management, and the ecological outcomes in terms of reduced alien plant cover and native vegetation recovery.
