Rapid biodiversity assessment of spiders (Araneae) using semi-quantitative sampling: a case study in a Mediterranean forest
Pedro Cardoso,Nikolaj Scharff,Clara Gaspar,Sérgio Henriques,Sérgio Henriques,Rui Carvalho,Pedro Humberto Castro,Jesper B. Schmidt,Israel F. Silva,Tamas Szüts,Alberto Castro,Luis C. Crespo +11 more
TL;DR: A thorough inventory of a Mediterranean oak forest spider fauna carried out during 2 weeks used a semi‐quantitative sampling protocol to collect comparable data in a rigorous, rapid and efficient way.
Journal ArticleDOI
Species richness and composition assessment of spiders in a Mediterranean scrubland
Pedro Cardoso,Sérgio Henriques,Sérgio Henriques,Clara Gaspar,Luis C. Crespo,Rui Carvalho,Jesper B. Schmidt,Pedro Sousa,Tamás Szűts +8 more
TL;DR: Test results support the idea that the only variables that need to be controlled in similar protocols are the sampling methods and the time of day when each method is executed, and indicate that populations in structurally simple habitats present narrower peaks of adult abundance, which implies higher percentages of juveniles in samples.
Journal ArticleDOI
Determinants of beta diversity of spiders in coastal dunes along a gradient of mediterraneity
TL;DR: The main aim was to evaluate the relative effects of environmental and spatial variables and their scale‐specific importance on beta diversity patterns along a gradient of mediterraneity, using spiders as a model group.
Journal ArticleDOI
Biogeographic patterns of spiders in coastal dunes along a gradient of mediterraneity
TL;DR: In this paper, the authors used distance-decay of similarity, nestedness and co-occurrence metrics to explore spider distribution patterns in coastal dunes along a gradient of mediterraneity.
Journal ArticleDOI
Ad-Hoc vs. Standardized and Optimized Arthropod Diversity Sampling
TL;DR: A comparison of both sampling approaches applied for spiders in a natural area of Portugal reveals a standardized protocol with three main advantages: higher efficiency; more reliable estimations of true richness; and meaningful comparisons between undersampled areas.
