摘要:Recent evidence suggests that morphological divergence of the American crocodile ( Crocodylus acutus ) occurred in Greater Antilles under conditions of prolonged isolation and hybridization with the Cuban crocodile ( C. rhombifer ). We investigated morphological diversity in C...

摘要:It is important to quantify patterns of morphological diversity to enhance our understanding of variation in ecological and evolutionary traits. Here, we present a quantitative analysis of morphological diversity in a family of small mammals, the tenrecs (Afrosoricida, Tenrecidae...

摘要:... Northern Africa represents a major center of diversity of Daucus , with Tunisia thought to contain 11 species and seven subspecies. The greatest taxonomic problems, however, and the greatest economic importance relative to immediate use in breeding, is in a group of species...

摘要:... In this study, we aimed to analyze the intratumoral distribution of macrophages and fibroblasts in breast cancer (BC) based on the morphological diversity of tumor cells (tubular, alveolar, solid, trabecular and discrete structures) and the clinicopathological parameters of...

摘要:... The objectives of this study were to evaluate the performance in agronomic traits of cowpea entries (released and farmers’ cultivars, and gene bank accessions) from different sources, and to assess the extent of genetic diversity in this material to provide basic infor...

摘要:... Trypanosomatid parasites are an excellent example of this in which large morphological variations between species and life cycle stage occur, despite sharing well-conserved cytoskeletal and membranous structures. Here, using previously published reports in the literature of t...

摘要:Abstract(#br)Morphological approaches have been used extensively to understand assembly rules (species interactions, environmental filtering, and neutral processes) that structure ecological communities. Desert anurans cope with limited water by either being restricted to permane...

摘要:... We studied the distribution and morphological diversity of badlands in the upper Llobregat basin (Catalan Pyrenees, NE Spain), using remote sensing information (high-resolution orthophotos and complementary Landsat 8 imagery), digital elevation data, and regional information...

摘要:The critical roles of viruses in nutrient cycling are well established for marine ecosystems, but less is known for freshwater viruses about diversity, seasonality, and relationships with productivity and ecosystem trophic status. This study aimed to examine virus morphotype...

摘要:... Their morphological characteristics and biophysical properties depend on the degree of association and interactions between the self-assembling biomaterials. For the purpose of this study, chimeric nanosystems composed of phospholipid and amphiphilic diblock copolymers were d...
