Ecological Modelling

Unprecedented quantities of the brown floating macroalgae Sargassum have been recorded in the tropical North Atlantic Ocean. However, the environmental factors affecting holopelagic Sargassum spp. growth and survival remain poorly understood. Here, we developed a multi-reserve DEB model for Sargassum spp. to link environmental conditions (temperature, nutrients, and light) to the organism physiol…

• We develop a trait- and niche-based theoretical model to analyse invasion dynamics. • Generalist invaders profit from their strong competitiveness, while specialists profit from empty niche spaces. • Ecological specialisation and niche position strongly mediate invasion impact. • Optimal level of removal effort differs among diversity indices, emphasising that control programs should align thei…
