Predicting current and future global distribution of invasive Ligustrum lucidum W.T. Aiton: Assessing emerging risks to biodiversity hotspots

Diversity and Distributions, Journal Year: 2021, Volume and Issue: 27(8), P. 1568 - 1583

Published: June 3, 2021

Abstract Aim Biological invasions represent one of the main anthropogenic drivers global change with a substantial impact on biodiversity. This can be particularly acute in biodiversity hotspots. Ligustrum lucidum W.T. Aiton is tree species native China that, from as early eighteenth century, has been introduced broadly around globe, becoming serious invasive species. We aim to predict L. lucidum's current and future potential distributions at scale assess degree which hotspots are risk invasion. Location All continents. Methods Using presence data, climatic edaphic variables, we developed an ensemble model periods (2050 2080) distribution . Susceptible countries were identified. Results Important regions within neighbouring likely environmentally suitable, but they not currently occupied. Biodiversity South America highlighted being Notably, climate may increase risks across large extents hotspots, mainly Africa, especially by 2080 period. Main conclusions Current overlaps worldwide. Control challenge once established. Thus, modelling helps identify areas, guiding their detection or suitable areas. Our findings useful guide develop region‐specific invasion management strategies prevent and/or control this species' spread.

Functional traits explain crayfish invasive success in the Netherlands

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Published: Feb. 2, 2021

Abstract Biological invasions by nonindigenous species can have negative effects on economies and ecosystems. To limit this impact, current research biological uses functional traits to facilitate a mechanistic understanding of theoretical applied questions. Here we aimed assess the role in progression crayfish through different stages invasion determine associated with invasive success. A dataset thirteen 15 currently occurring or available for sale Netherlands was evaluated. Six these appeared invasive. Important distinguishing successful from unsuccessful invaders were temperate climate native range, medium high egg count producing more than one clutch per year. The most had trait combinations: Procambarus clarkii has higher reproductive output, migrate over longer distances possesses aggression level; Faxonius limosus is adapted colder climate, reproduce parthenogetically broader environmental tolerances. Using suit analyse potential help risk management prevention. For example, based our data virginalis predicted become next Netherlands.

Understanding trophic interactions in a warming world by bridging foraging ecology and biomechanics with network science

Integrative and Comparative Biology, Journal Year: 2024, Volume and Issue: unknown

Published: June 13, 2024

Synopsis Climate change will disrupt biological processes at every scale. Ecosystem functions and services vital to ecological resilience are set shift, with consequences for how we manage land, natural resources, food systems. Increasing temperatures cause morphological shifts, concomitant implications biomechanical performance metrics crucial trophic interactions. Biomechanical performance, such as maximum bite force or running speed, determines the breadth of resources accessible consumers, outcome interspecific interactions, thus structure networks. change-induced impacts ecosystem therefore on horizon, mediated by disruptions and, consequently, interactions across whole ecosystems. Here, argue that there is an urgent need investigate complex between climate change, traits, foraging ecology help predict changes networks functioning. We discuss these seemingly disparate disciplines can be connected through network science. Using ant-plant example, illustrate different data types could integrated interaction warming, force, what integration achieve. It our hope this integrative framework identify a viable means elucidate previously intractable effective predictive potential guide management mitigation.
