Abstract:

Objective: This study aims to evaluate the relative importance of phylogenetic, environmental, and spatial components in explaining the floristic variation of tree communities, with the goal of understanding the different processes shaping tree assemblages in Brazil. Methodology: The methodology adopted for this research includes the construction of eigenvectors to operationalize the predictor variables (phylogeny, environment, and space) in our models. We employed variation partitioning using canonical models, predicting that the phylogenetic component would play a stronger role in explaining

Abstract:

Variation in traits across species or populations is the outcome of both environmental and historical factors. Trait variation is therefore a function of both the phylogenetic and spatial context of species. Here we introduce a method that, within a single framework, estimates the relative roles of spatial and phylogenetic variations in comparative data. The approach requires traits measured across phylogenetic units, e.g. species, the spatial occurrences of those units and a phylogeny connecting them. The method modifies the expected variance of phylogenetically independent contrasts to inclu

Abstract:

The eukaryotic ribosomal DNA cluster consists of multiple copies of three genes, 18S, 5. 8S and 28S rRNAs, separated by multiple copies of two internal transcribed spacers, ITS1 and ITS2. It is an important, frequently used marker in both molecular cytogenetic and molecular phylogenetic studies. Despite this, little is known about intragenomic variations within the copies of eukaryotic ribosomal DNA genes and spacers. Here we present data on intraindividual variations of ITS2 spacer in three species of Agrodiaetus Hübner, 1822 blue butterflies revealed by cloning technique. We demonstrate that

Abstract:

Utilizing the technique of DNA – DNA hybridization, we have characterized the degree of genetic variability in single-copy DNA both within and between several species of Drosophila. The results of intraspecific variation studies indicate considerable variation both for levels of nucleotide heterozygosity (estimated to be over 2%) as well as for insertions–deletions. Interspecific studies confirm this great deal of variability and further establish an extreme heterogeneity within Drosophila genomes for rates of divergence. This heterogeneity is much more extreme than that seen between exons and

SUMMARYWe investigated spatial variation in the phylogenetic structure of host spectra in fleas parasitic on small mammals. Measures of phylogenetic host specificity ((phylogenetic species clustering (PSC) and phylogenetic species variability (PSV)) varied significantly more between than within flea species, but the proportion of variation which accounted for among-species differences was low. In 13 of 18 common flea species, at least one of the indices of the phylogenetic structure of regional host spectra revealed a significantly positive association with the phylogenetic structure of region

Abstract:

BackgroundAssembly of species into communities following human disturbance (e.g., deforestation, fragmentation) may be governed by spatial (e.g., dispersal) or environmental (e.g., niche partitioning) mechanisms. Variation partitioning has been used to broadly disentangle spatial and environmental mechanisms, and approaches utilizing functional and phylogenetic characteristics of communities have been implemented to determine the relative importance of particular environmental (or niche-based) mechanisms. Nonetheless, few studies have integrated these quantitative approaches to comprehensively

Abstract Mitochondria contain a maternally inherited 16,568bp genome (mtDNA) that encodes for 13 out of more than 70 subunits of complexes of the respiratory chain that produce ATP by oxidative phosphorylation (OXPHOS). As a byproduct of OXPHOS, reactive oxygen species (ROS) are formed, which may play a role in ageing. MtDNA has accumulated numerous polymorphisms during evolution, leading to haplogroups characterized by ancient polymorphisms and defined by letters. MtDNA polymorphisms are thought to be neutral, but some may be slightly deleterious or even advantageous and may influence phenoty

Brachyglottis (Asteraceae) is a genus of approximately 30 species in the Brachyglottidinae, a recently recognised sub-tribe of tribe Senecioneae.

A sixth species, B. saxifragoides, has recently been synonymised with B. lagopus. The rosette-Brachyglottis have historically been recognised as a taxonomically problematic group because species overlap in both morphology and geographical distribution.

Abstract Mitochondrial DNA (mtDNA) is a maternally inherited 16.6 kbp circular genome that codes for 13 subunits of the mitochondrial respiratory chain, 2 rRNAs and 22 tRNAs. The mutation rate in mtDNA is high and therefore, mutations have accumulated sequentially to lineages that have diverged tens of thousands of years ago. The neutral theory predicts that a proportion of these variations may be slightly deleterious, associated with diseases and selected against, but the issue is still controversial.

Assim, ecótonos campo-floresta são sistemas adequados para inferir sobre a influência de processos históricos, biogeográficos e ecológicos na estruturação de comunidades.

Abstract:

In the large body of literature on ecological and evolutionary mechanisms underlying transitions between planktotrophy and lecithotrophy, the focus has typically covered long evolutionary timescales; that is, evolution of complex larval traits is generally discussed in the context of phylogenetic patterns detectable at the level of families, classes, or phyla. An analytical approach incorporating comparative phylogenetics is increasingly used to address these long-view questions.

Abstract:

The objectives of this project were to: 1) Identify genetic markers linked to sex-determining genes in various experimental and commercial stocks of O. niloticusand O. aureus, as well as red tilapias; 2) Develop additional markers tightly linked to these sex determiners, and develop practical, non-destructive genetic tests for identifying genotypic sex in young tilapia; A third aim, to map sex modifier loci, was removed during budget negotiations at the start of the project. Background to the topic. A major obstacle to profitable farming of tilapia is the tendency of females to reproduce at a

Abstract:

In Colombia, Venezuela, Ecuador, Brazil and Honduras, the tomato borer, Neoleucinodes elegantalis, is the most important fruit-related plague of the Solanaceae family. A suitable molecular characterization using a DNA barcoding system is necessary to clarify different issues inside the taxonomy of Neoleucinodes genus. Additionally, other DNA sequences used for molecular identification and phylogenetics studies, can be implemented to obtain a better understanding of the genetic variability across different animal groups and allows to acquire a enhanced description of the population s genetic va
