Biogeography of tenebrionid beetles (Coleoptera: Tenebrionidae) in the circum-Sicilian islands (Italy, Sicily): Multiple biogeographical patterns require multiple explanations

open access: yesEuropean Journal of Entomology, 2011
The tenebrionid beetles on 25 circum-Sicilian islands were studied to determine the influence of island geographical and landscape features on three main intercorrelated biogeographical patterns: (1) species richness, studied using species-area and ...

Genetic characterization of flea-derived Bartonella species from native animals in Australia suggests host-parasite co-evolution [PDF]

open access: yes, 2011
Fleas are important arthropod vectors for a variety of diseases in veterinary and human medicine, and bacteria belonging to the genus Bartonella are among the organisms most commonly transmitted by these ectoparasites.

A barrier island perspective on species–area relationships [PDF]

open access: yesEcology and Evolution, 2018
AbstractPredictions of species richness by island area are a classical cornerstone in ecology, while the specific features of barrier islands have been little appreciated. Many shorelines are occupied by barrier islands, which are shaped by offshore sedimentation processes and annual storm tide events.

Composition and biogeography of forest patches on the inland mountains of the southern Cape

open access: yesBothalia: African Biodiversity & Conservation, 1997
Patterns in species richness of 23 small, isolated forests on the inland mountains of the southern Cape were studied. Species richness of woody plants and vines of the Kouga-Baviaanskloof Forests was higher than in the western mountain complexes, where ...

Classification and mapping of the woody vegetation of Gonarezhou National Park, Zimbabwe [PDF]

open access: yes, 2016
Within the framework of the Great Limpopo Transfrontier Conservation Area (GLTFCA), the purpose of this study was to produce a classification of the woody vegetation of the Gonarezhou National Park, Zimbabwe, and a map of its potential distribution ...

Common spatial patterns of trees in various tropical forests: Small trees are associated with increased diversity at small spatial scales

open access: yesEcology and Evolution, 2021
Tropical forests are notable for their high species diversity, even on small spatial scales, and right‐skewed species and size abundance distributions.

Spatial Scaling Patterns of Functional Diversity

open access: yesFrontiers in Ecology and Evolution, 2021
Ecology, biogeography and conservation biology, among other disciplines, often rely on species identity, distribution and abundance to perceive and explain patterns in space and time.

A global model of island species–area relationships [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Significance The island species–area relationship (ISAR) is a fundamental diversity pattern, best described by the power model. Biogeographic theory assumes predictable variation in power model parameters in relation principally to system isolation, but these assumptions are only weakly supported by previous work, which has been limited in ...

Response of Bird Populations to Long-term Changes in Local Vegetation and Regional Forest Cover [PDF]

open access: yes, 2016
We analyzed data from a woodland site for a 59-year period to determine whether changes in bird populations are related to changes in the diversity and relative abundance of woody plant species even when vegetation structure, degree of forest ...

Scale Dependence and the Species-Area Relationship

open access: yesThe American Naturalist, 1994
The complex relationship between species richness and area can be simplified by decomposing spatial scale into its components: grain, extent, and number of samples. We designed a 256 x 256-m study grid in the Oosting Natural Area in the Duke Forest, Orange County, North Carolina, such that the effects of these components can be disentangled.
