AbstractConservation programmes are always limited by available resources. Careful planning is therefore required to increase the efficiency of conservation and gap analysis can be used for this purpose. This method was used to assess the representativeness of current ex situ and in situ conservation actions of 234 priority crop wild relatives (CWR) in Indonesia. This analysis also included species distribution modelling, the creation of an ecogeographical land characterization map, and a complementarity analysis to identify priorities area for in situ conservation and for further collecting of ex situ conservation programmes. The results show that both current ex situ and in situ conservation actions are insufficient. Sixty-six percent of priority CWRs have no recorded ex situ collections. Eighty CWRs with ex situ collections are still under-represented in the national genebanks and 65 CWRs have no presence records within the existing protected area network although 60 are predicted to exist in several protected areas according to their potential distribution models. The complementarity analysis shows that a minimum of 61 complementary grid areas (complementary based on grid cells) are required to conserve all priority taxa and 40 complementary protected areas (complementary based on existing protected areas) are required to conserve those with known populations within the existing in situ protected area network. The top ten of complementary protected areas are proposed as the initial areas for the development of CWR genetic reserves network in Indonesia. It is recommended to enhanced coordination between ex situ and in situ conservation stakeholders for sustaining the long term conservation of CWR in Indonesia. Implementation of the research recommendations will provide for the first time an effective conservation planning of Indonesia’s CWR diversity and will significantly enhance the country’s food and nutritional security.

The Subject

Conservation of genetic resources of forest trees has become a major objective for the management of forests. Much theoretical work has been devoted to the subject, and implementation has already started at the local, national, or international scales. Poplars are probably the most representative and threatened forest tree species of old natural floodplain forests in the temperate zone. Gene conservation needs to be integrated with intensive breeding activities, habitat conservation and restoration. For Populus nigra, while research in genetics and ecology is reinforced, a combined conservation strategy is applied at the European scale; simultaneously, the conservation of riparian ecosystems is also a priority. Research and application benefit from each other. The question now is the evaluation of such an integrated strategy. Criteria and indicators for the follow-up of gene resource management are progressively developed, but still need to be tested on the operational scale. Key words: Populus nigra, poplar, gene resources, in situ conservation, ex situconservation, riparian ecosystem, sustainable management

Priority Direction

The aim of the article is to summarize the results of plant gene pool samples introduction into the National Plant Genebank from different countries and ecological and geographical zones for use in domestic breeding. Results and Discussion. In 2016 – 2018, 5984 samples were introduced to the Centre for Plant Genetic Resources of Ukraine using various information sources, including 2093 samples from Ukraine and 3891 from foreign countries. The greatest samples variety was attracted by cereals, leguminous, fodder, medicinal and essential oil, vegetable and melon crops, corn. Seeds of new forms having valuable properties are attached from research and breeding institutions of Ukraine. The samples of foreign origin were most actively introduced through cooperation with research institutions of Russia, Belarus, and Moldova. A significant number of samples came from genebanks in Europe: the Czech Republic, Italy, France, Germany, the Netherlands; Asia: Kazakhstan Turkey, Israel, China as well as from South (Mexico) and North America - USA, Canada. The ways of pre-adaptation and adaptation of samples from geographically remote regions for use in Ukraine are indicated. To collect local cultural and wild-growing samples of different crops, collecting missions were carried out in the central and southern regions of the forest-steppe and northeastern regions of Ukraine during which 1641 gene pool samples were collected. For the Red Book species of plants and species that are not listed in the Red Book of Ukraine but are rare or are threatened with extinction under natural conditions, a points have been identified for possible arrangement of in situ conservation reserves. A number of objects with a rich genetic diversity of fodder and medicinal plants have been identified, on which it is necessary to monitor coenoses and ensure in situ conservation. The introduced samples were transferred for use in research and breeding programs in Ukraine. Conclusions. The definition of a model of ecologically adapted in Ukraine genotypes of different crops that are carriers of valuable traits from countries with similar climatic conditions as well as from geographically remote regions, has made it possible to increase the efficiency of introduction and to more specifically search and attract to the National Genebank the plant samples with the necessary manifestation levels of economic and biological traits.

The purpose of this study was to carry out an inventory of medium and large-sized mammal species occurring in the Mata Atlântica State Park (MASP). Located in Água Limpa municipality, state of Goiás, the MASP occupies an important area with a seasonal forest remnant, which is considered an enclave of the Atlantic Forest within the Cerrado biome. From October 2012 to December 2013, MASP’s area was randomly surveyed for evidence of mammal presence. Records of 23 species of wild mammals were obtained, seven of them listed as nationally endangered. Medium and large-sized mammal species composition is characteristic of the Cerrado biome, and no endemic species of the Atlantic Forest were recorded. Richness and diversity of the mammal species recorded in MASP show the importance of this protected area for in situ conservation.

Aim: collection of local wild and cultural gene pool accessions of the plants adapted to the conditions of Dnipropetrovska and Kharkivska oblasts of Ukraine for selection from them ones valuable on economic and biological traits, including them in the plant-breeding and research programs and maintenance in collections of the National Plant Genebank of Ukraine. Results and Discussion. There is carried out expeditionary inspection of the districts of Dnipropetrovska and Kharkivska regions of Ukraine. 473 gene pool accessions of cultural plants and wild relative forms adapted to the conditions of this region related to 165 botanical species are collected. 274 herbarium sheets of 53 plant species are prepared. Natural reserves and objects of the naturally-protected fund are explored for seed collection of rare and regionally rare species, and also vegetation of burial mounds, ravines, beams, slopes, undisturbed steppe areas. Points for the establishment of in situ conservation reserves have been identified. The collected material will ensure the expansion of the genetic base of existing and the creation of new genetic resources collections of field, medicinal and other crops due to samples characterized by adaptability to stress abiotic and resistance to biotic factors, productivity, product quality. Conclusions. 473 seeds packages and planting material units of gene pool accessions are collected during the expedition and transferred to research institutions for the study. The results of the expedition showed the promise of continuing expeditionary surveys and collecting gene pool samples in Ukraine. To do this, it is necessary to equip the NCPGRU with a specialized vehicle and provide for a special article to finance expeditions.

Ecological Zones

We present a comprehensive approach to carry out community-wide assessments of in situ conservation of forest trees based on basic botanical and ecological data. This is a first step, resulting in a consistent framework to set priorities for collection and inclusion of species- specific biological and genetic information. We use botanical sample data to generate high-resolution distribution maps as a basis for a gap analysis of how well each species is represented in protected areas. To account for adaptive genetic variation of tree species we stratify populations by ecological zones that represent different macroclimates. In a detailed example for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), we show that under certain conditions this approach can pinpoint gaps at the level of genetically differentiated populations without actually using genetic data. In a comprehensive case study, evaluating the outcome of a major protected area expansion between 1991 and 2001 for British Columbia, we demonstrate how extensive results from a community-wide GIS analysis can be summarized and presented for decision-making. We provide methods to identify and efficiently cope with in situ conservation gaps, where lack of data or low protected area coverage requires additional conservation efforts or collection of better data.

Starting Point

The genetic structure of black poplar (Populus nigra L.) populations in the area of Great War Island (GWI) was studied at the level of 30 genotypes, based on microsatellite molecular markers (SSR). Eleven polymorphic SSR loci were used for analysis of intarpopulation genetic variability. Observed and expected heterozygosity in studied population were high (0.70 and 0.82). The fixation index calculated for single locus ranged from -0.055 (PMGC_14) up to 0.424 (PMGC_2607), while the mean value was 0.143. Deviation from Hardy-Weinberg equilibrium (HWE) differed between single loci. Stabile genetic structure and satisfactory level of genetic variability that have been determined at the population level represent a good starting point for conservation and sustainable use of the available gene pool and further breeding of this species.
