Eco-evolutionary feedbacks : theoretical models and perspectives Universiteit Gent KU Leuven
A future for cacti?: case study of the Chilean genus Copiapoa Universiteit Gent
The endemic flora of the Chilean biodiversity hotspot is increasingly threatened by habitat loss due to anthropogenic causes and climate change. This study focuses on threatened cactus species of which the evolution and genetic diversity have not yet been studied using molecular approaches. Also, the genetic diversity present in ex situ collections is undetermined and has not been compared with the diversity in nature. In this project, ...
Climate change impact on seaweed meadow distribution in the North Atlantic rocky intertidal Vlaams Instituut voor de Zee
The North-Atlantic has warmed faster than all other ocean basins and climate change scenarios predict sea surface temperature isotherms to shift up to 600 km northwards by the end of the 21st century. The pole-ward shift has already begun for many temperate seaweed species that are important intertidal foundation species. We asked the question: Where will climate change have the greatest impact on three foundational, macroalgal species that ...
Parallel diversifications of Cremastosperma and Mosannona (Annonaceae), tropical rainforest trees tracking Neogene upheaval of South America Universiteit Gent
Much of the immense present day biological diversity of Neotropical rainforests originated from the Miocene onwards, a period of geological and ecological upheaval in South America. We assess the impact of the Andean orogeny, drainage of Lake Pebas and closure of the Panama isthmus on two clades of tropical trees (Cremastosperma, ca 31 spp.; and Mosannona, ca 14 spp.; both Annonaceae). Phylogenetic inference revealed similar patterns of ...
Do well-integrated species of an inquiline community have a lower brood predation tendency? : a test using red wood ant myrmecophiles Universiteit Gent KU Leuven
Background: A host infected with multiple parasitic species provides a unique system to test evolutionary and ecological hypotheses. Different parasitic species associated with a single host are expected to occupy different niches. This niche specialization can evolve from intraguild competition among parasites. However, niche specialization can also be structured directly by the host when its defence strategy depends on the parasite's potential ...
A process-based metacommunity framework linking local and regional scale community ecology Vrije Universiteit Brussel KU Leuven
The metacommunity concept has the potential to integrate local and regional dynamics within a general community ecology framework. To this end, the concept must move beyond the discrete archetypes that have largely defined it (e.g. neutral vs. species sorting) and better incorporate local scale species interactions and coexistence mechanisms. Here, we present a fundamental reconception of the framework that explicitly links local coexistence ...
Niche evolution reveals disparate signatures of speciation in the ‘great speciator‘ (white-eyes, Aves : Zosterops) Universiteit Gent
Dynamic species distribution models reveal spatiotemporal habitat shifts in native range-expanding versus non-native invasive birds in an urban area Universiteit Gent Universiteit Antwerpen
Urbanisation as a major driver of changes leads to the extinction of some species while others increase in abundance, especially non-native species. Spatiotemporal distribution patterns of these successful species are likely to be shaped by their response and tolerance to urban features. This study assesses the anthropo-ecological requirements of two co-occurring bird species, the native range-shifting jackdaw Corvus monedula and the non-native ...
Trophic consequences of introduced species: Comparative impacts of increased interspecific versus intraspecific competitive interactions Instituut voor Natuur- en Bosonderzoek
1. Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on resident species, results are equivocal. In addition, quantifying the relative strength of impacts from non-native species (interspecific competition) versus the release of native conspecifics ...
