Integrating plot-based methods for monitoring biodiversity in island habitats u...
Borges, P.A.V.; Nunes Morgado, Leila; Gabriel, Rosalina; Pires Bento da Silva Elias, Rui Miguel; Gauche, Miharisoa; Ah-Peng, Claudine; Otto, RüdigerABSTRACT: Oceanic islands are globally recognised for their exceptional levels of biodiversity and endemism, often resulting from unique evolutionary processes in isolated environments. However, this biodiversity is also disproportionately threatened by anthropogenic pressures including habitat loss, invasive species and climate change. Targeted, long-term biodiversity monitoring is essential for detecting chan...
Collective and harmonized high throughput barcoding of insular arthropod biodiv...
Emerson, Brent C.; Borges, Paulo A. V.; Cardoso, Pedro; Convey, Peter; deWaard, Jeremy R.; Economo, Evan P.; Gillespie, Rosemary G.; Kennedy, SusanABSTRACT: Current understanding of ecological and evolutionary processes underlying island biodiversity is heavily shaped by empirical data from plants and birds, although arthropods comprise the overwhelming majority of known animal species, and as such can provide key insights into processes governing biodiversity. Novel high throughput sequencing (HTS) approaches are now emerging as powerful tools to overcom...
MtDNA metagenomics reveals large-scale invasion of belowground arthropod commun...
Cicconardi, Francesco; Borges, Paulo A. V.; Strasberg, Dominique; Oromí, Pedro; López, Heriberto; Pérez-Delgado, Antonio J.; Casquet, JulianeUsing a series of standardized sampling plots within forest ecosystems in remote oceanic islands, we reveal fundamental differences between the structuring of aboveground and belowground arthropod biodiversity that are likely due to large-scale species introductions by humans. Species of beetle and spider were sampled almost exclusively from single islands, while soil-dwelling Collembola exhibited more than ten...
A combined field survey and molecular identification protocol for comparing for...
Emerson, Brent C.; Casquet, Juliane; López, Heriberto; Cardoso, Pedro; Borges, Paulo A. V.; Mollaret, Noémy; Oromí, Pedro; Strasberg, DominiqueObtaining fundamental biodiversity metrics such as alpha, beta and gamma diversity for arthropods is often complicated by a lack of prior taxonomic information and/or taxonomic expertise, which can result in unreliable morphologically based estimates. We provide a set of standardized ecological and molecular sampling protocols that can be employed by researchers whose taxonomic skills may be limited, and where ...
Topography-driven isolation, speciation and a global increase of endemism with ...
Steinbauer, Manuel J.; Field, Richard; Grytnes, John-Arvid; Trigas, Panayiotis; Ah-Peng, Claudine; Attorre, Fabio; Birks, H. John B.AIM: Higher-elevation areas on islands and continental mountains tend to be separated by longer distances, predicting higher endemism at higher elevations; our study is the first to test the generality of the predicted pattern. We also compare it empirically with contrasting expectations from hypotheses invoking higher speciation with area, temperature and species richness. Location Thirty-two insular and 18 co...
