Journal of Fish Biology (76)7 2010
Abstract
The distributional patterns of the seven species of Rhizoprionodon were analysed using the panbiogeographical method of track analysis. The individual tracks of Rhizoprionodon suggest that the genus is mainly an Indian-Atlantic Ocean group. Five generalized tracks were found: (1) Caribbean, defined...

Abstract
We evaluated conservation concerns that noise limits bird distributions and reduces nesting success via a natural experiment to isolate the effects of noise from confounding stimuli and to control for the effect of noise on observer detection biases. We show that noise alone reduces nesting species...

Abstract
We estimate not individual variability (plasticity) proper but generalized population or taxonomic epigenetic diversity of intracreode, which in actually becomes an extracreode. Population-meronomic analysis of bilateral compositions of antimere structure elements allows to construct a natural syste...

Abstract
Evolution of organisms is adaptive process as a whole, but its adaptiveness is fully revealed in long periods of phylogenesis. To form the complex adaptations, the phyletic evolution is more favourable than relatively short-term processes of speciation. Selection can influence on a given character o...

Abstract
The estimation of (co)variance components for multiple traits with maternal genetic effects was found to be influenced by population structure. Two traits in a closed breeding herd with random mating were simulated over nine generations. Population structures were simulated on the basis of different...

Abstract
We investigated whether zebrafish respond differentially to a natural predator or other fish species upon their first exposure to these fish. Naïve zebrafish were shown four species of fish chosen based on predatory status (predatory or harmless) and geographical origin (allopatric or sympatric). O...

Abstract
To detect signatures of natural selection and thus identify genetic bases for adaptation to anthropogenic stressors, we examined allele frequencies for many hundreds of amplified fragment length polymorphism markers among populations of F. heteroclitus. Specifically, we contrasted populations from t...

Abstract
We hypothesized that unique RABV variants might be associated with mtDNA lineages of Colorado big brown bats. DNA was extracted from brain tissue of rabid big brown bats, the ND2 gene was amplified to determine mtDNA lineage, and the lineage was compared to a previously derived phylogenetic analysis...

Abstract
We introduce a graph theoretical characterization that helps to assess whether given set of characters is appropriate to use with parsimony methods. Given a set of characters and a set of taxa, we construct a network called character overlap graph. We show that the character overlap graph for charac...

Abstract
We used intracellular recording to compare photoreceptor spectral sensitivity in B. t. sassaricus and the southern European and Mediterranean population, B. t. dalmatinus. The results show both populations to be UV-blue-green trichromats, but with a small but significant increase in long-wave sensit...

Abstract
We present previously undescribed spatial group patterns that emerge in a one-dimensional hyperbolic model for animal group formation and movement. The patterns result from the assumption that the interactions governing movement depend not only on distance between conspecifics, but also on how indiv...

Abstract
We interviewed 137 people (67 men and 70 women), who provided information on animal species used as remedies, body parts used to prepare the remedies, and illnesses to which the remedies were prescribed. Comparisons were made using cluster analysis. Interviewees quoted 138 animal taxa, 11 of which a...

We develop a relationship that predicts the change in relative body size variation within a cohort will be approximately equal to the relative change in mean per unit size growth rate, when only size-dependent factors affect growth. When modeling cohort growth, relative size variation decreased, rem...

Abstract
For nine genes for phylogenetically independent comparisons between 50 metazoan phyla, orders, and classes, we find a significant correlation between average body size and rate of molecular evolution of mitochondrial genes. The data also indicate that diversification rate may have a positive effect...

Abstract
We outline the concept and the realm of populations with explicit spatial and temporary boundaries. We call such populations "temporally bounded populations". In the concept, time is of the same importance as space in terms of a dimension to which a population is restricted. Two parameters not avail...

Abstract
We show that, despite the difference in the timing of egg laying, males from these two populations start seasonal hypothalamo-hypophysial-testicular development at approximately the same time, in late winter. Specifically, the vernal recrudescence of brain GnRH-I perikarya and fibers, testes volume...

Furthermore, the Slug Mucosal Irritation test is a reliable method to classify chemicals accurately into three eye irritation categories based on the mucus pro...

We used empirical data for six microsatellite loci and offspring from full-sib crosses of hatchery strains of lake trout (Salvelinus namaycush; Salmonidae) representing known levels of coancestry (mean theta = 0.006 and 0.06) within families to investigate how gene correlations can affect assignment...

Abstract
We develop a patch-model of a whole plant-animal community and explore its persistence. To assess the role of network structure, we build three versions of the model. In the first version, we use the exact network of interactions of two real mutualistic communities. In the other versions, we randomi...

We have chosen a strategy that we suggest is superior to others that have gone previously. We have ignored multigene families and instead have used single-gene families. This minimizes the inadvertent analysis of paralogs. We have employed strict data controls and have reasoned that if a protein is...

Renal accumulation of advanced glycation end products (AGEs) has been linked to the progression of diabetic nephropathy. Cleavage of pre-formed AGEs within the kidney by a cross-link breaker, such as ALT-711, may confer renoprotection in diabetes. STZ diabetic rats were randomized into a) no treatme...

A multimedia program, a non-linear system which supplements the traditional, linear way of learning (e.g. with a text book), was developed.

Motif refinement of the peroxisomal targeting signal 1 and evaluation of taxon-specific differences.
Abstract
We derived the requirements for a C-terminal amino acid sequence to interact productively with Pex5. We found evidence that, at least the 12 C-terminal residues of a given substrate protein are implicated in PTS1 signal recognition. This motif can be structurally and functionally divided into three...
