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.

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.

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 ...

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 ...

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.

Modelling the distribution of the invasive Roesel’s bushcricket (Metrioptera roeselii) in a fragmented landscape [PDF]

open access: yes, 2011
The development of conservation strategies to mitigate the impact of invasive species requires knowledge of the species ecology and distribution. This is, however, often lacking as collecting biological data may be both time-consuming and resource ...

The impact of the species-area relationship on estimates of paleodiversity. [PDF]

open access: yesPLoS Biology, 2005
Estimates of paleodiversity patterns through time have relied on datasets that lump taxonomic occurrences from geographic areas of varying size per interval of time. In essence, such estimates assume that the species-area effect, whereby more species are

Global priorities for conservation across multiple dimensions of mammalian diversity [PDF]

open access: yes, 2017
Conservation priorities that are based on species distribution, endemism, and vulnerability may underrepresent biologically unique species as well as their functional roles and evolutionary histories.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

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 ...
