Good taxonomy is essential for ecological, biogeographical, and evolutionary studies of any group of organisms. Therefore, we performed detailed light- and scanning electron microscopy (SEM) investigations on the shell ultrastructure and biometric analyses ...
Background: In this study we compare outlier loci detected using a FST based method with those identified by a recently described method based on spatial analysis (SAM). We tested a panel of single nucleotide polymorphisms (SNSPs) previously genotyped in i ...
Invasive plant species represent a threat to terrestrial ecosystems, but their effects on the soil biota and the mechanisms involved are not yet well understood. Many invasive species have undergone polyploidisation, leading to the coexistence of various c ...
Megalorhina Westwood (type species: Ceratorhina (Megalorhina) harrisii Westwood, 1847) was synonymysed previously with Amaurodes Westwood (type species: Ceratorhina (Amaurodes) passerinii Westwood, 1844), and Amaurodes ranked as a subgenus of Mecynorhina H ...
Sulfonated anthraquinones are precursors of a large family of synthetic dyes and pigments, recalcitrant to biodegradation and thus not eliminated by classical wastewater treatments. In the development of a phytotreatment to remove sulfonated aromatic compo ...
The genus Eudicella White comprises horned cetoniines widespread in the sub-Saharan Africa. Two subgenera, Eudicella (Eudicella) White and Eudicella (Cyprolais) Thomson, compose the genus. Here, the remarkably uniform subgenus Eudicella (Eudicella) is revi ...
Minimal state representations are parsimonious models having no redundant states. For homogeneous reaction systems with S species, R independent reactions, p independent inlet streams and one outlet stream, a nonlinear transformation of the numbers of mole ...
Structural studies of substituted 1,3,5-benzenetrisamides, a new family of highly versatile and efficient nucleating and clarifying agents for polymeric materials, are reported. Subtle details of the molecular structure of these species are shown to have a ...
We study the observed geographic distribution of freshwater fish species in the Mississippi-Missouri river system, focusing on the size and spatial distribution of geographic ranges. We use a particular metric of geographic distribution known as environmen ...
Predicting species distribution is of fundamental importance for ecology and conservation. However, distribution models are usually established for only one region and it is unknown whether they can be transferred to other geographical regions. We studied ...
