Rapid population recovery of a foundation species from experimental small-scale harvesting.

Ecological stability is central to understanding how disturbances challenge the persistence of populations and communities through time, especially when key species are impacted. The bull kelp Durvillaea incurvata is a foundation, habitat-forming species that provides food and shelter for various species and supports the livelihoods of human communities along the Chilean coast. Harvesting of Durvillaea has raised concerns about the long-term viability of its populations, but the stability responses of Durvillaea to anthropogenic disturbances remain unclear.

Species Removal Dampens the Scale Dependency of Ecological Determinism and Stochasticity in Coastal Communities.

Deterministic and stochastic processes control community dynamics. However, the responses of both processes to the loss of foundation species, which strongly influence community dynamics across spatial scales, are unclear. We experimentally examined how spatial extent and foundation species removal affect rocky-intertidal community dynamics over 3 years in eight field sites spanning ~1000 km along the southeastern Pacific.

Transient species driving ecosystem multifunctionality: Insights from competitive interactions between rocky intertidal mussels.

Anthropogenic biodiversity loss poses a significant threat to ecosystem functioning worldwide. Numerically dominant and locally rare (i.e.

Can suitability indices predict plant growth in the invaded range? The case of Acacias species.

Introduction: Forestry in many parts of the world depends on exotic species, making this industry a source of invasions in some countries. Among others, plantations of the genus Pinus, Eucalyptus, Acacia, Populus, and Pseudotsuga underpin the forestry industry and are a vital component of many countries economies. Among woody plants, the cosmopolitan genus Acacia includes some of the most commonly planted trees worldwide.

Foundation species canopies affect understory beta diversity differently depending on species mobility.

Beta diversity measures the spatial variation in species composition. Because it influences several community attributes, studies are increasingly investigating its drivers. Spatial environmental heterogeneity is a major determinant of beta diversity, but canopy-forming foundation species can locally modify environmental properties.

Integrating species and interactions into similarity metrics: a graph theory-based approach to understanding community similarity.

Community similarity is often assessed through similarities in species occurrences and abundances (i.e., compositional similarity) or through the distribution of species interactions (i.

Positive and negative effects of mesograzers on early-colonizing species in an intertidal rocky-shore community.

The ecological consequences of human-driven overexploitation and loss of keystone consumers are still unclear. In intertidal rocky shores over the world, the decrease of keystone macrograzers has resulted in an increase in the dominance of herbivores with smaller body (i.e.
