Ecological Gradients in Diversity and Abundance: A Search for Patterns and Processes in Small Mammal Communities
… questions in ecology is: what are the patterns of diversity and the mechanisms that produce them? Many biological theories have been proposed to explain latitudinal and elevational diversity gradients, but no accepted, general explanation for the distribution of biodiversity has …

Evolution of major histocompatibility complex genes in New World bats and their functional importance in parasite resistance and life-history decisions in the lesser bulldog bat (Noctilio albiventris)
… I aimed to gain insights in the evolution and diversity pattern of functional MHC genes in some of the major New World bat families by establishing species-specific primers through genome-walking into unknown flanking parts of familiar sites. Further, I took a free-ranging population of the …

Molecular characterization of sediment bacterial communities affected by fish farming
… farming process. This is also supported by the diversity pattern of the merA gene between farm and pristine sediments. The bacterial community-level changes in response to fish farming were very complex and no single phylogenetic groups were found that would be typical to fish farm sediments. …

COEXISTENCE, RESILIENCE AND RESISTANCE OF MARINE INVERTEBRATE COMMUNITIES ACROSS A LATITUDINAL GRADIENT
… of the most fundamental processes underlying the patterns of species diversity and community structure across biogeographical scales is therefore vital, especially as humans increasingly modify these relationships established over the course of geological history. The latitudinal diversity …

Bryophyte and macrolichen diversity of the Purdiaea nutans forest in southern Ecuador and its relationship to soil, climate and vegetation structure
… beta diversities reveals no universally valid pattern for lichens, liverworts, mosses, and ferns. The results indicate that diversity patterns for epiphytic and terrestrial species are distinct and should be treated separately. Among the studied taxonomic groups, ferns and liverworts show most …
