Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

Biological Diversity, EarlyView.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

Density Estimates of Endangered Endemic Rodents Suggest Broader Impacts of Invasive Burmese Pythons Following a Category 4 Hurricane in the Florida Keys

Biological Diversity, EarlyView.
Density estimates of two endangered rodent subspecies, endemic to Key Largo, Florida, USA. These findings illustrate the contrasting dynamics of two native species associated with the prevalence of invasive Burmese pythons and global change. The woodrats' decline emphasizes its potential risk of extinction as global change continues to impact island ...

Antimicrobial Activity of Three Endemic Verbascum Species

Pharmaceutical Biology, 2002
The extracts obtained from three Verbascum L. species (Verbascum olympicum Boiss., Verbascum prusianum Boiss., and Verbascum bombyciferum Boiss.) have been investigated for their antimicrobial activity. Growth inhibition, using the agar disc diffusion assay, was determined against Escherichia coli ATCC 11230, Micrococcus luteus La 2971, Staphylococcus ...

Species richness and endemism in the native flora of California

American Journal of Botany, 2017
PREMISE OF THE STUDY:California's vascular flora is the most diverse and threatened in temperate North America. Previous studies of spatial patterns of Californian plant diversity have been limited by traditional metrics, non‐uniform geographic units, and distributional data derived from floristic descriptions for only a subset of species.METHODS:We ...

The systematics and genetics of tomatoes on the Galápagos Islands (Solanum, Solanaceae)

, 2009
Galápagos tomatoes (Solanum section Lycopersicon) have long interested scientists and plant breeders. Several morphological and physiological characters found in the endemic Galápagos tomatoes have been bred into the cultivated Solanum lycopersicum ...

Phylogeography and allopatric divergence in cypress species (Cupressus L.) in the Qinghai-Tibetan Plateau and adjacent regions [PDF]

, 2010
Additional files can be found at http://www.biomedcentral.com/1471-2148/10/194Background Although allopatric speciation is viewed as the most common way in which species originate, allopatric divergence among a group of closely related species has rarely

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.
