A Review of a Rare Type of Anomaly in Amphibians, Tail Duplication and Bifurcation, with Description of Three New Cases in European Species (Triturus dobrogicus, Triturus carnifex, and Hyla arborea) / Klaus Henle, Bela Mester, Szabolcs Lengyel, Miklos Puky
Dátum:

Megjegyzések:
We review the natural occurrence of tail duplications and tail bifurcations in amphibians as well as experimental studies that induced tail duplications. For natural populations, we found 10 publications that mention tail duplications or bifurcations in a total of 24 individual larval amphibians belonging to 15 species, mainly from Europe and South America. Nineteen publications describe the incidence for 34 individual postlarval urodeles from 12 species from North America, Europe, and Asia. Here we add three new observations: a subadult female Triturus dobrogicus with a duplicated tail and an adult female Triturus carnifex with a bifurcated tail from Hungary, and a tadpole of Hyla arborea with a bifurcated tail tip from Greece. The causes of tail duplications in wild amphibians remain unknown. Similar tail anomalies have been obtained in the laboratory when parts of the chorda dorsalis were destroyed, when tar is injected into the tail, or when the lumbar region is irradiated.

Biodiversity conservation measures and biological processes oftendo not match in scale. The EU funded project SCALES (Securing theConservation of biodiver sity across Administrative Levels and spatial,temporal, and Ecological Scales) is intended to solve this challenge.SCALES analyses how selected pressures (climate change, habitatloss, fragmentation, disturbance), their drivers, and their impactson biodiversity change with spatial and temporal scale. The projectdevelops methods for a better understanding of scaling propertiesof biological processes from the genet ic level to populations,communities, and ecosystem functions. SCALES also seeks waysto integrate the issue of scale into policy, decision-making, andbiodiversity management, focusing on networks of protectedareas, regional connectivity, and biodiversity monitoring.

Integrating ongoing biodiversity monitoring: potential benefits and methods / Pierre-Yves Henry, Szabolcs Lengyel, Piotr Nowicki, Romain Julliard, Jean Clobert, Tatjana Čelik, Bernd Gruber, Dirk S. Schmeller, Valerija Babij, Klaus Henle
Dátum:

Halting the loss of biodiversity comes along with the need to quantify biodiversity composition and dynamics at large spatial and temporal scales. Highly standardized, international monitoring networks would be ideal, but they do not exist yet. If we are to assess changes in biodiversity now, combining output available from ongoing monitoring initiatives is the only option. However, integration of biodiversity information across schemes is still very poorly developed. In this paper, we outline practical issues to be considered when planning to combine existing monitoring information. First, we provide an overview of avenues for integration along the four dimensions that characterize a monitoring design: sample size, biological coverage, spatial coverage and temporal coverage. We also emphasize that complementarity in monitoring targets across schemes enables to describe complex processes of biodiversity dynamics, e.g. through relating species traits to the impacts of environmental changes. Second, we review some methods to overcome differences in designs among monitoring schemes, such as site selection, poststratification and measurement error. Finally, we point out some commonly used statistical methods that are at hand for combining data or parameter estimates. We especially emphasize the possible levels of data integration (raw data, parameter estimates, or effect size estimates), and the largely under-exploited potential of meta-analysis methods and weighted analyses. This contribution aims to bolster the practice and use of integration of ongoing monitoring initiatives for biodiversity assessment.

A review and a framework for the integration of biodiversity monitoring at the habitat level / Szabolcs Lengyel, Andrej Kobler, Lado Kutnar, Erik Framstad, Pierre-Yves Henry, Valerija Babij, Bernd Gruber, Dirk Schmeller, Klaus Henle
Dátum:
2008
Megjegyzések:
The monitoring of biodiversity at the level of habitats is becoming widespread in Europe and elsewhere as countries establish national habitat monitoring systems and various organisations initiate regional and local schemes. Parallel to this growth, it is increasingly important to address biodiversity changes on large spatial (e.g. continental) and temporal (e.g. decade-long) scales, which requires the integration of currently ongoing monitoring efforts. Here we review habitat monitoring and develop a framework for integrating data or activities across habitat monitoring schemes. We first identify three basic properties of monitoring activities: spatial aspect (explicitly spatial vs. non-spatial), documentation of spatial variation (field mapping vs. remote sensing) and coverage of habitats (all habitats or specific habitats in an area), and six classes of monitoring schemes based on these properties. Then we explore tasks essential for integrating schemes both within and across the major classes. Finally, we evaluate the need and potential for integration of currently existing schemes by drawing on data collected on European habitat monitoring in the EuMon project. Our results suggest a dire need for integration if we are to measure biodiversity changes across large spatial and temporal scales regarding the 2010 target and beyond. We also make recommendations for an integrated pan-European habitat monitoring scheme. Such a scheme should be based on remote sensing to record changes in land cover and habitat types over large scales, with complementary field mapping using unified methodology to provide ground truthing and to monitor small-scale changes, at least in habitat types of conservation importance.

Megjegyzések:
Without robust and unbiased systems for monitoring, changes in natural systems will remain enigmatic for policy makers, leaving them without a clear idea of the consequences of any environmental policies they might adopt. Generally, biodiversity-monitoring activities are not integrated or evaluated across any large geographic region. The EuMon project conducted the first large-scale evaluation of monitoring practices in Europe through an on-line questionnaire and is reporting on the results of this survey. In September 2007 the EuMon project had documented 395 monitoring schemes for species, which represents a total annual cost of about ?4 million, involving more than 46,000 persons devoting over 148,000 person-days/year to biodiversity-monitoring activities. Here we focused on the analysis of variations of monitoring practices across a set of taxonomic groups (birds, amphibians and reptiles, mammals, butterflies, plants, and other insects) and across 5 European countries (France, Germany, Hungary, Lithuania, and Poland). Our results suggest that the overall sampling effort of a scheme is linked with the proportion of volunteers involved in that scheme. Because precision is a function of the number of monitored sites and the number of sites is maximized by volunteer involvement, our results do not support the common belief that volunteer-based schemes are too noisy to be informative. Just the opposite, we believe volunteer-based schemes provide relatively reliable data,with state-of-the-art survey designs or data-analysis methods, and consequently can yield unbiased results. Quality of data collected by volunteers is more likely determined by survey design, analytical methodology, and communication skills within the schemes rather than by volunteer involvement per se.

National Responsibilities in European Species Conservation: a Methodological Review / Dirk S. Schmeller, Bernd Gruber, Eduardas Budrys, Erik Framsted, Szabolcs Lengyel, Klaus Henle
Dátum:
2008
Megjegyzések:
One particular challenge in reducing the loss of biodiversity by 2010, as agreed on at the Earth Summit in 2002, is to assign conservation tasks to geographic or administrative entities (e.g., countries or regions) on different geographical scales. To identify conservation tasks, it is imperative to determine the importance of a specific area for the global survival of a species. So far, these national or subnational responsibilities for the conservation of species have been included differently in methods prioritizing conservation. We reviewed how 12 European and 3 non-European methods determined national conservation responsibilities and evaluated the international importance of a biological population. Different countries used different methodologies, which made a direct comparison of assessments of national responsibilities among countries extremely difficult. Differences existed in the importance criteria used. Criteria included population decline, range reduction, rarity status, degree of isolation of a population, endemism, proportional distribution, and geographic location. To increase comparability, it is imperative to develop criteria for which data are generally available and to standardize the methodology among countries. A standardized method would allow conservation decisions to be based on the conservation status of a species and on the responsibility of a geographic or administrative entity for the survival of a species. We suggest that such a method should use a scalable index of proportional distribution, taxonomic status, and the distribution pattern of a taxon or species as key elements. Such a method would allow for the creation of hierarchical lists and would be highly relevant for parts of the world with multiple political jurisdictions or state unions and for nations with regional governmental structures. Conservation priorities could then be reasonably set by combining national responsibility assessments with the international conservation status of a species.
