Resumen
Abstract Populations of animals comprise many individuals, interacting in multiple contexts, and displaying heterogeneous behaviors. The interactions among individuals can often create population dynamics that are fundamentally deterministic yet display unpredictable dynamics. Animal populations can, therefore, be thought of as complex systems. Complex systems display properties such as nonlinearity and uncertainty and show emergent properties that cannot be explained by a simple sum of the interacting components. Any system where entities compete, cooperate, or interfere with one another may

Resumen
Prediction the dynamics of the level and structure of regional hunting resources is relevant from the standpoint of their rational use. Matrix models are widely used to make predictions on the dynamics of hunting animal populations. The algorithm of the modified P. H. Leslie matrix model with a correction matrix is used. The accuracy of predictions on the dynamics of hunting animal populations based on matrix models is improved by their verification. In the proposed study, model verification is considered not only as a method for determining the correspondence of the model to the corresponding

Resumen
This paper reviews the main characteristics of small and/or closed livestock populations. Although the emphasis during the realization of the genetic improvement in animal breeding is put on commercial breeding programmes, autochthonous breeds, races, strains, even herds of domestic animas, at the same time represent a potentially important segment for achieving the maintenance of the overall livestock production. These programmes are particularly important for the improvement of populations of animal genetic resources, as well as for the improvement of production in rural marginal areas. One

Resumen
Humans are dependent on the animals they raise and breed for food and secondary products. Archaeological and genetic investigations can provide critical insights into the history and development of these breeds and help understand human activities in the past. Furthermore, many well-adapted breeds are endangered and archaeological and genetic data can help inform future breed conservation choices. Utilising ancient DNA data could potentially permit detailed diachronic analyses of the development of animal breeds. Ancient DNA analyses have typically focussed on large-scale biogeographic pattern

Resumen
Biological management of populations plays an indispensable role in all areas of population biology. In deciding between possible management options, one of the most important pieces of information required by population managers is the likely population status under possible management actions. Population dynamic models are the basic tool used in deriving this information. These models elucidate the complex processes underlying the population dynamics, and address the possible consequences/merits of management actions. These models are needed to guide the population towards desired/chosen man

Resumen
Individual loci affecting economic traits in dairy cattle (ETL) have been detected via linkage to genetic markers by application of the granddaughter design in the US population and the daughter design in the Israeli population. From these analyses it is not possible to determine allelic frequencies in the population at large, or whether the same alleles are segregating in different families. We proposed to answer this question by application of the "modified granddaughter design", in which granddaughters with a common maternal grandsire are both genotyped and analyzed for the economic traits.

Resumen
Restoring wildlife populations requires locating, protecting, and connecting areas where species can thrive under both ecological and anthropological conditions. Addressing these spatial needs may be difficult, as required habitats may have been lost, fragmented, or altered prior to restoration. Changes in land use may also lead to increased human-animal interactions that impact restoration outcomes. In this exercise, students consider these issues in a case study of Florida panthers (Puma concolor coryi), a currently federally protected carnivore that has a growing population in the state of

There is strong scientific evidence that climate change is already impacting plant and animal populations, and model projections indicate that the current trends are likely to continue over the coming century. This module includes a synthesis and presentation that reviews case studies from the primary scientific literature on the observed effects of climate change on biodiversity and an exercise that has participants explore the communication and interpretation of climate change science through role-playing as climate scientists or journalists.
