I bought this book, then I recieved an invitation to review this book, but I can not do it because the book never arrived to my home (of course they took the money out of my credit card). I guess I wil have to buy it somewhere else

metapopulation theory uncovered.......2000-03-30

I found this text useful in explaining the concepts of metapopulation theory. A general framework of metapopulation models is presented in the first several chapters, beginning with Levin's metapopulation model and subsequent variants. Hanski presents the incidence function model (an approach using the presence/absence of species in habitat patches), his own contribution to the field, in some detail. Most theoretical and mathematical constructions are followed by examples, which is nice. The final section of the book is a case study that was very helpful in understanding the application of theories discussed earlier in the text.

Book Description

Meta-X is a user-friendly computer program that allows students, teachers, and researchers to perform a metapopulation viability analysis i.e. to assess the extinction risk of (meta)populations on discrete, partially isolated patches of habitat, in a comfortable way. The CD comes with an extensive handbook which explains the basic concept of the program and takes you on a guided tour through a model experiment. It further provides the necessary scientific background on both metapopulation dynamics and population viability analysis.
A special feature of Meta-X is that it supports comparative analyses of alternative scenarios. This predestines Meta-X to serve as an aid for decision making in conservation management and landscape planning. Furthermore, handbook and software together provide an invaluable help in research and teaching.

Book Description

Development of rural landscapes is converting once-vast expanses of open space into pockets of habitat where wildlife populations exist in isolation from other members of their species. The central concept of metapopulation dynamics-that a constellation of partially isolated patches can yield overall stability to a system that is chaotic at the level of the individual patch-offers an important new way of thinking about the conservation and management of populations dispersed among small habitat fragments. This approach is proving to be a rich resource for biologists hoping to arrest the current catastrophic loss of biodiversity.

An understanding of metapopulation theory and analysis is critical to the modern practice of wildlife conservation and management. This volume provides a comprehensive overview of the subject, addressing the needs of an applied professional audience for comprehensible information to integrate into their practices. Leading conservation biologists, ecologists, wildlife managers, and other experts consider the emergence and development of metapopulation theory and explore its applicability and usefulness to real-world conservation programs.

Introductory chapters provide background information on basic concepts such as models, genetics, landscape configuraton, and edges and corridors. Subsequent chapters present detailed methods of analyzing metapopulation structure. Case studies of an array of vertebrate species, including the Swedish pool frog, the northern spotted owl, Stephens' kangaroo rat, Florida scrub jay, Mediterranean monk seal, Steller sea lion, tule elk, and others, illustrate nuances of metapopulation theory analysis and its practical applications.

Contributors describe what metapopulation approaches bring to wildlife conservation and management, present models of how metapopulation thinking has been applied in specific situations, and suggest the analysis required in given cases. Metapopulations and Wildlife Conservation is essential reading for anyone working in the field of wildlife conservation and managment.

Description:
The harvest of non-timber forest products (NTFPs) represents a significant source of income for hundreds of millions of people, and is promoted as a conservation and development strategy across the globe. Most research on NTFP management focuses on the dynamics of individuals within harvested populations, but the ways in which management may affect the dynamics of populations across a landscape and over time remain largely unexplored. Here, I use a metapopulation framework to assess the effects of management on populations of the fiber-harvested bromeliad, Aechmea magdalenae, in the Sierra Santa Marta, Mexico. Specifically, I quantify rates of colonization, extinction and growth as well as size structure of A. magdalenae populations from 1997 to 2003; and compare these variables between wild versus outplanted populations and between old-growth versus secondary forest populations. Over the 5-year study period, 42% of the 31 wild A. magdalenae populations went extinct due to anthropogenic fires and to ramet harvest for the creation of enrichment plantings. Significantly more secondary forest populations went extinct than old-growth forest populations. Sixty-two outplanted populations were created and in contrast to wild populations and despite harvest, these outplantings increased in size and none went extinct. The structure of wild populations shifted towards fewer populations with less rosettes but overall numbers and sizes of populations increased. These results illustrate the dynamic nature of A. magdalenae populations over both time and space and the ways in which the fates of populations depend on decisions made by harvesters at both the population and the landscape level. In this case, sustainable harvest of A. magdalenae does not necessarily ensure population persistence. Outplanting of A. magdelanae appears to be functioning as a very successful forest conservation strategy. Nonetheless, the conservation of at least some wild populations may be required to ensure long-term survival of this species in this region. Metapopulation approaches may provide an important compliment to demographic studies of A. magdalenae and other NTFP.

Description:
It is well known that adult dispersal is common in soft bottom intertidal and shallow subtidal communities. We here report on the first study that attempts to quantify the effects of both immigration and emigration on patches of soft sediment communities. Some species show adaptive emigration from the seabed, although dispersal direction, distance, and colonization success are probably strongly dependent on hydrodynamics, morphological adaptations to dispersal, and the ability to select appropriate target microsites. The naid oligochaete Paranais litoralis is a numerically dominant benthic species in southern New England and New York mud flats and tends to reproduce mainly or exclusively by means of budding of new individuals. When population density is high and resources in short supply, budding frequency is reduced, worms grow longer, and may emigrate from the sediment. We quantified emigration by means of a conical trap and quantified immigration with sediment dishes. We followed emigration/immigration during the typical late spring population explosion and crash cycle of worms within the sediment, which is driven by a seasonal cycle of provision and exhaustion of organic detrital food supply. Emigration was proportionally maximal either at or after the population peak, consistent with a response to food shortage. Over a span of ca. 50 m, we found no net movement in either direction along a transect, nor was emigration or immigration correlated with local density in the sediment. Nevertheless, both emigration and immigration were important in our 2004 sampling, and immigration especially had an important impact on population densities. We do not know the relative capture efficiencies of the emigration and immigration apparatus, so more needs to be done to understand the impacts of dispersal in this and other systems.

Description:
An important result of population genetics is that advantageous mutations will be fixed by selection in a population with a greater probability if they are dominant rather than recessive. This selective filter on new variants entering a population, termed 'Haldane's Sieve', has hitherto been invoked to account for the greater role of dominant than completely recessive mutations in adaptive evolution. Here, we suggest that a process similar to Haldane's Sieve will act on migrants into subpopulations of a metapopulation, and that the repeated action of Haldane's Sieve on alleles maintained by frequency-dependent selection, such as those responsible for many plant reproductive polymorphisms, is expected to bias their frequency distribution in favour of dominant alleles. The genetic and phenotypic signatures left by these processes might provide additional indirect support for the contentious idea that metapopulation dynamics have had an important role in shaping the ecology and evolution of some plant species.

Description:
Mnesampela privata is an Australian geometrid moth that is considered to have resource-driven outbreaks. An autumnal oviposition/larval development cycle is considered the ''norm'' in this species, but spring/summer activity has also been observed. This apparent plasticity of phenology and probable concomitant changes in voltinism have not been considered as possible causes of moth outbreaks. We developed GumMoth, a phenological model for M. privata that uses temperature to predict development times of immatures. Photoperiod determines whether individuals undergo direct development or pupal diapause. We used known catch dates of moths (in the same moth-active season or 365-day period) to simulate population phenologies on the Australian mainland (27^o28'S to 38^o14'S) and in Tasmania (40^o54'S to 42^o57'S). GumMoth successfully simulated phenological patterns that agreed with published records and demonstrated for the first time that multivoltinism is possible in M. privata. In seven paired simulations using dates for first and last moth catches, the earliest moth activity resulted in the pupae of four out of 11 generations undergoing diapause, whereas the latest moth activity resulted in pupae of five out of eight generations undergoing diapause (diapause individuals emerged the following moth-active season). Almost two-thirds of offspring of spring/summer active moths reached adulthood within that same moth-active season (i.e. no delay in development), whereas those of autumn active moths always reached adulthood the following moth-active season (i.e. development was delayed). Records from foresters and in the scientific literature confirmed that the more common autumn phenology is supplemented by spring/summer activity in many localities. At half of these localities, populations that required insecticide control or caused substantial defoliation also developed. Because plantation eucalypts are suitable M. privata hosts for only four to five tree-growth seasons after planting, local moth populations must increase quickly if an outbreak is to occur. We suggest that large populations are more likely when plantations are colonised in the first moth-active season after planting and population growth commences in the spring/summer of each subsequent year. Foresters can use catch dates and regional weather data in GumMoth to estimate the number and phenology of generations of M. privata. This information can be used to assess risk posed by regional populations and thereby adjust future surveillance intensity.
