Najas genties augalų genetinės įvairovės tyrimas taikant SCoT žymenis /
… of the bodies. For this reason, the genetic diversity of 6 Lithuanian populations of N. marina and N. major was investigated using SCoT (Start codon targeted) markers and compared with ISSR (Inter simple sequence repeats) marker data of another PhD student. The results of principal coordinate …

The role of intrinsic and extrinsic factors in shaping alternative migratory tactics and metabolic phenotypes in brown trout
… for a considerable portion of phenotypic diversity produced in nature, and is instrumental to the structure and function of ecosystems. Understanding how, and why, intraspecific diversity persists is essential for predicting and managing the effects of global change, particularly because …

Interplay between competition and evolution in invaded and native plant communities
… I investigated the ecological consequences of intraspecific diversity in Pseudoroegneria. I found that functional diversity within the species increased ecosystem productivity, and that this pattern was strongest for ecotypes from mesic environments, suggesting that adaptive variation …

Behavioural Ecology in Conservation Planning: Individual and Sex-Specific Insights from Woodland Caribou (Rangifer tarandus caribou) in Western Canada
Conservation planning often relies on delineating intraspecific units to capture ecological and evolutionary diversity. To do this, traditional frameworks often emphasize genetic or taxonomic criteria as a first line of evidence for evolutionary significance. While useful, this approach assumes …

Evolution of the Hominoid Vertebral Column
… This survey, in combination with analyses of intraspecific diversity and interspecific similarity, suggests that reduced lumbar regions are homologous in extant hominoids. Furthermore, hominoid vertebral formulae are unique among primates and relatively unique among mammals in general. …

Spatial and Temporal Patterns of Genetic Variation in Scarlet Macaws: Implications for Population Management in La Selva Maya, Central America
… importance of Central American populations to intraspecific diversity. Focusing on A. m. cyanoptera, mitochondrial control region sequences of 850 base pairs were examined within a hierarchical context to investigate patterns of genetic substructure at varying spatial scales and extent of …

The double life of an insect pathogen: Metarhizium as a plant symbiont and its genetic diversity in coffee agroecosystems
… in an ecological context and data about their diversity and abundance in agricultural soils and in association with plant rhizosphere are very sparse, especially in tropical ecosystems. Also, considering the ability to form mutualistic association with plants, no Metarhizium’s specific …

The Effect of Population History on Hominoid Intraspecific Cranial Shape Diversity: Combining Population Genetic and 3D Geometric Morphometric Data
<p>Cranial shape diversity within hominoids has been previously studied with the aim of understanding how levels of diversity in extant species compare with extinct hominin specimens. This dissertation addresses the question of why cranial shape diversity differs among extant hominoids. Levels of …

COMPARATIVE GENOMICS OF CHEMOSENSORY GENE FAMILIES AMONG MEMBERS OF THE HELIOTHINAE
… and applies these tools to examine inter- and intraspecific diversity of chemosensory genes among members of the Heliothinae.In chapter 2, I produced a novel Illumina short read C. subflexa genome assembly and an improved, highly contiguous C. virescens genome assembly. Due to quality …

The potential impact of climate change on the genetic diversity of the endangered western leopard toad, Sclerophrys pantherina
… of the greatest threats to the persistence of biodiversity. Much work has focused on the potential for climatic shifts to alter species' ranges, phenology, physiology, and behaviour, addressing higher level units of biodiversity from populations to biomes. However, the potential effects of climate …

Adaptation of an invasive grass to agriculture: ecological and genomic evidence
… ecological processes. Ecologically meaningful intraspecific variation might be particularly important in the context of agricultural weeds and exotic invaders, because intraspecific variation in these species might allow them to rapidly adapt to their unusually dynamic and variable …
