Повний текст джерелаENGLISH ABSTRACT: Habitat loss and fragmentation are major threats to global biodiversity. A cornerstone of traditional conservation involves setting aside land as formally protected areas (PAs). However, for effective biological conservation in the long term there needs to be connectivity between these PAs. When possible, improved connectivity can be achieved using natural corridors at a landscape scale. Even better is to establish a network of corridors and nodes in the form of ecological networks (ENs). ENs are currently being employed by commercial forestry companies in South Africa. While larger corridors and nodes are considered optimum, factors other than design, such as management and environmental heterogeneity, have also been found to be important for species maintenance. This study aims to explore the role of corridor width in driving the composition of invertebrate assemblages across a transformed landscape in KwaZulu-Natal, South Africa, and to investigate other possible environmental variables significant for species distributions. In Chapter 2, I investigated the contribution of smaller grassland corridors within a timber production matrix to overall biodiversity conservation using two important bioindicator taxa. Ants and dung beetles were sampled in grassland corridors of three size classes, plantation blocks and a nearby PA, iMpendle Nature Reserve. The two taxa showed differential responses to landscape level fragmentation. Dung beetles showed a decrease in species richness and corresponding increase in species turnover with increased fragmentation, while ants were unaffected, although counter intuitively smaller corridors even contained more unique ant species compared to larger corridors. Dung beetle assemblages also showed strong differences between the PA and grassland corridors. While the conservation effectiveness of large corridors undoubtedly exceeds that of smaller corridors, for ants it seems that smaller corridors contribute to their overall conservation within this production landscape. In Chapter 3, I explore the importance of spatial and environmental factors for species distribution across this landscape. Dung beetles were split into functional guilds according to size and nesting behaviour for analyses. Within grassland corridors, tunnelling dung beetle species richness was sensitive to landscape level fragmentation, especially for larger species, while elevation and vegetation type influenced ant species richness. Since rolling dung beetles showed a close association with the PA, the marked difference in dung beetle assemblages between these two land-uses may be due to the presence of pellet producing grazers in the protected area and their replacement by pat producing cattle in the grassland corridors. Other environmental variables that were found to be important for dung beetle species composition were elevation, vegetation type, and soil hardness. For ant species composition, only elevation was found to be important. In conclusion, as large corridors were comparable to the PA in dung beetle and ant species richness, ENs act as extensions of formally PAs, given that they are large enough. Nevertheless, smaller corridors had surprisingly high species richness. Including additional information other than species data improved our knowledge of the underlying factors that drive dung beetle species composition. Even though dung beetle and ant species responded differentially to habitat fragmentation, environmental heterogeneity seemed important for both taxa. Incorporating habitat heterogeneity into the current management scheme may improve the conservation effectiveness within this transformed landscape.
AFRIKAANSE OPSOMMING: Die vermindering en fragmentasie van natuurlike habitat is ‘n groot bedreiging vir globale biodiversiteit. ‘n Belangrike tradisionele benadering tot natuurbewaring behels die afbakening van land vir formele beskermde areas (BAs). Ten einde effektiewe biologiese bewaring oor die langtermyn te verseker moet daar verbinding wees tussen hierdie BAs. Indien moontlik kan verbeterde verbinding verkry word deur die gebruik van natuurlike gange op ʼn landskaps-vlak. Nog beter is om ʼn netwerk van gange en nodes in die vorm van ekologies netwerke (ENe) saam te stel. ENe word tans deur kommersiële bosboumaatskappye in Suid Afrika aangewend. Terwyl groter gange en nodes as optimaal beskou word, is ander faktore behalwe ontwerp, soos bestuur en omgewingsheterogeniteit, ook al gevind as belangrik vir die onderhouding van spesies. Hierdie studie is gemik daarop om die rol van gangwydte as dryfkrag vir die samestelling van invertebraatversamelings oor ʼn getransformeerde landskap in KwaZulu-Natal, Suid-Afrika, te ondersoek, asook ander moontlike omgewingsveranderlikes wat belangrik vir spesiesverpreidings kan wees. In Hoofstuk 2 het ek die bydrae van kleiner gange tot totale biodiversiteit-bewaring ondersoek deur twee belangrike bio-indikator taxa te bestudeer. Miere en miskruiers is versamel in grasland-gange van drie grootte-klasse, plantasie blokke en ‘n naby geleë BA, iMpendle Natuurreservaat. Die twee taxa het verskillende reaksies tot landskaps-vlak fragmentasie getoon. Miskruiers het ‘n verlaging in spesiesrykheid en ‘n gesamentlike verhoging in spesiesomset met verhoogde fragmentasie gewys, terwyl miere nie geaffekteer is nie, alhoewel kleiner gange het trouens meer unieke mierspesies bevat as groter gange. Die miskruierversamelings in die BA het ook opmerklik verskil van dié in die grasland-gange. Alhoewel die bewaringsdoeltreffendheid van groot gange beslis dié van kleiner gange oorskry, kom dit voor dat kleiner gange wel bydra tot die totale bewaring van miere binne hierdie produksielandskap. In Hoofstuk 3 het ek die belangrikheid van ruimtelike en omgewingsfaktore vir spesiesverspreiding oor hierdie landskap ondersoek. Miskruiers is ook in funksionele groepe verdeel volgens grootte en nes-gedrag vir aparte analise. Binne grasland-gange was tonnellende miskruierspesies sensitief vir landskaps-vlak fragmentasie, veral groter spesies, terwyl hoogte bo seevlak en vegetasie tipe mier spesiesrykheid beïnvloed het. Aangesien rollende miskruierspesies ‘n nabye assosiasie met die BA gewys het, mag die opmerklike verskil in miskruier versamelings tussen hierdie twee grondgebruike ʼn gevolg wees van die aanwesigheid van korrel-mis produserend beweiders in die BA en hulle vervanging deur nat-mis produserende beeste in die grasland-gange. Omgewingsveranderlikes uitsluitende ganggrootte wat belangrik gevind is vir miskruier spesiessamestelling was hoogte bo seevlak, vegetasie tipe en grond-hardheid. Vir mier spesiessamestelling was slegs hoogte bo seevlak belangrik. Om af te sluit, aangesien groot gange vergelykbaar was met die BA in miskruier en mier spesiesrykheid, tree ENe op as uitbreidings van BAs, mits hulle groot genoeg is. Desnieteenstaande het kleiner gange ‘n verbasende hoë spesiesrykheid gehad, veral onder miere. Die insluiting van addisionele inligting buiten spesiesdata het ons kennis van die onderliggende faktore wat miskruier spesiessamestelling dryf verbeter. Alhoewel miskruier- en mierspesies verskillend gereageer het op habitat fragmentasie, het dit voorgekom asof omgewingsheterogeniteit belangrik was vir die spesiesverspreiding van beide taxa. Die insluiting van habitatheterogeniteit binne die huidige bestuursplan mag die doeltreffendheid van bewaring binne hierdie getransformeerde landskap verbeter.

Повний текст джерелаLes tensions causées par la fragmentation sur la biodiversité et la distribution d'espèces seront exacerbées par les changements climatiques qui déplacent les régions bioclimatiques. L'amélioration de la connectivité grâce aux corridors faciliterait le mouvement et la conservation de la végétation en fournissant un délai de dispersion pertinent au changement climatique. Nous avons évalué cette hypothèse en nous concentrant sur les espèces herbacées forestières se dispersant au travers d'agroécosystèmes en utilisant des haies. Trente-et-une des quarante-deux espèces dans ces forêts ont été trouvées dans les haies, bien que les taux de dispersion au-travers des corridors, calculés sur l'année à moins de ou égal à 2.50 mètres, indiquent que les corridors ne favoriseraient pas la dispersion de ces espèces dans des conditions rapidement changeantes. Les espèces ont tendance à se rassembler dans les corridors, mais nos résultats suggèrent que la connectivité ne conserverait la diversité qu'à long-terme; les espèces sont limitées par la dispersion et possiblement par les conditions environnementales.Mots-clés: diversité végétale, corridor biologique, changements climatiques, fragmentation du paysage, connectivité, dispersion, conservation.

This work explores urban riparian corridors and their rolein the dynamic of plant communities based on a gradient of urbanization. Indeed, riparian corridors provide astructural connection between the city and the countryside, and their conservation involves preciselyunderstanding their ecological functionality. The objectives of this work are to highlight the effect of the urbanization gradient on the composition and structure of plant communities along a river to determine whether the existence of urban riparian corridors effectivelycontributes to the colonization of adjacent areas. Two rivers, the Bruche and the Rhin Tortu - Ziegelwasser, arestudied in their most urban downstream part in the metropolitan area of Strasbourg, eastern France. [...]

Повний текст джерелаThe Atlantic Forest is one of the biomes with the highest biodiversity in the world. Included among the 25 global hotspots due to its endemism, has today, 35% of plant species in Brazil, and many of these species are threatened with extinction. Compared to other countries and even other continents will, the biodiversity of the Atlantic Forest region is of global importance, being essential to their conservation. Brazil has the greatest diversity of World monkeys (48%), and, most endemic country, 2/3 of this amount occurring in the Atlantic Forest. Due to its wild habitat, have suffered great pressure by fragmentation in Atlantic Forest region, restricting habitats of populations to small fragments. The present study consists of a survey of presence and absence of Callithrix aurita, it is a species of primate rare, vulnerable and endemic Atlantic Forest. The importance of this survey is due to the current situation of the Atlantic Forest biome, particularly in the type of vegetation in the region studied, semideciduous forest, where there are the greatest deforestation for agricultural purposes and pasture due to climate, soil type, and other anthropogenic such as property market and building industries. Another factor that was considered is the presence of invasive species as Callithrix jacchus and Callithrix penicillata. The study was conducted in the state of Rio de Janeiro, the city of Sapucaia in the district of Vila Nossa Senhora Aparecida. We evaluated 11 fragments which registered the presence of Callithrix aurita in 8 of these fragments. To assist, we used the method play-back and questionnaires with residents and local workers. The council has a large agricultural exploration, and a total lack of environmental planning by local government. With the results of this survey, along with historical data collected, it was found that the municipality has a high environmental value. Even with the vulnerable status of the species, and its rarity, it is present in 70% of the fragments studied, and no record of invasive species, becoming fundamental to implementing a conservation plan, with the support of the public and society. The objective of this survey is to assist in defining priority areas for future creation of conservation units, using Callithrix aurita as flagship species, assisting in the work of environmental education and public awareness, exploring the potential tourist, historical, religious, among others the municipality for a better environment and a better quality of life for the region's population.

Повний текст джерелаENGLISH ABSTRACT: The ultimate goal of conservation planning is to ensure persistence of biodiversity. Biodiversity patterns and ecological processes are important aspects in conserving biodiversity. Although most researchers in conservation planning have focused on targeting biodiversity patterns, ecological and evolutionary processes can ensure persistence of biodiversity if incorporated into conservation planning. Ecological processes are the main drivers or sustainers of biodiversity. The aim of this research was to identify and map the spatial components of ecological processes in a portion of the Kavango Zambezi Transfrontier Conservation Area to aid in the implementation of biota movement corridors. Different methods have been used to identify suitable corridors but not much has been done on defining and mapping ecological processes that will ensure that the corridors maintain and generate biodiversity. A thorough literature survey was done to make a list of ecological processes that are important in maintaining the biodiversity in the area. Spatial components of ecological processes were mapped as surface elements aligned along linear environmental interfaces or gradients. The last part of the research was to suggest suitable movement corridors based on ecological processes. The results include five spatial components: riverine corridors, areas of high carbon sequestration, edaphic interfaces, upland-lowland interfaces and ecotones. Riverine corridors were mapped using a 1000 m buffer on either side of low lying rivers and 500 m buffer around rivers in the uplands. A map showing the carbon sequestration potential of vegetation in the study area was made using Moderate-Resolution Image Spectroradiometer (MODIS) derived NDVI data and the National Level Carbon Stock dataset done by the Woods Hole Research Center (WHRC) Pantropical. Edaphic interfaces were idenfied using by a 250 m buffer around contrasting soil types. Upland-lowland interfaces identified by a 250 m buffer along upland and lowland habitats. Classification of Landsat 8 was used to identify ecotones in the study area. The results of the spatial components were then compared with the habitat transformation map which shows populated areas.
AFRIKAANSE OPSOMMING: Die uiteindelike doel van bewaringsbeplanning is om voortbestaan van biodiversiteit te verseker. Biodiversiteitspatrone en ekologiese prosesse is belangrike aspekte in die bewaring van biodiversiteit. Alhoewel die meeste navorsers in bewaringsbeplanning fokus op teiken biodiversiteitspatrone, kan die voortbestaan van ekologiese en evolusionêre prosesse van biodiversiteit verseker word deur insluiting in bewaringsbeplanning. Ekologiese prosesse is die belangrikste drywers, of onderhouers, van biodiversiteit. Die doel van hierdie navorsing was dus om die ruimtelike komponente van ekologiese prosesse in 'n gedeelte van die Kavango Zambezi oorgrensbewaringsgebied te identifiseer en te karteer om te help met implementering van biota bewegingsdeurlope. Verskillende metodes is al gebruik om gepaste deurlope te identifiseer, maar min navorsing is gedoen oor definisie en kartering van ekologiese prosesse om te verseker dat die deurlope biodiversiteit sal onderhou en genereer. 'n Deeglike literatuurstudie is gedoen om 'n lys op te stel van ekologiese prosesse wat belangrik is in die handhawing van biodiversiteit in die gebied. Ruimtelike komponente van ekologiese prosesse is gekarteer as oppervlak elemente gebonde aan lineêre omgewingskoppelvlakke of gradiënte. Die laaste deel van die navorsing was om geskikte bewegingsdeurlope, gebaseer op ekologiese prosesse, voor te stel. Die resultate sluit vyf ruimtelike komponente in: rivierdeurlope, gebiede van hoë koolstofsekwestrasie, edafiese koppelvlakke, hoogland-Laeveld koppelvlakke en grensekotone. Rivierdeurlope is gekarteer met behulp van 'n 1000 meter buffer aan weerskante van laagliggende riviere en 500 meter buffer rondom riviere in die hooglande. ‘n Kaart wat die koolstofsekwestrasiepotensiaal van plantegroei in die studie area toon is gemaak met behulp van Moderate-Resolution Image Spectroradiometer (MODIS) afgeleide NDVI data en ʼn koolstofvoorraaddatastel (National Level Carbon Stock dataset) voorsien deur die Woods Hole Research Center (WHRC). Pantropiese edafiese koppelvlakke is geïdentifiseer met behulp van 'n 250 meter buffer rondom kontrasterende grondtipes. Hoogland-Laeveld koppelvlakke is geïdentifiseer deur 'n 250 meter buffer langs die berg en laagland habitatte. Klassifikasie van Landsat 8 data is gebruik om ekotone in die studie area te identifiseer. Die resultate van die ruimtelike komponente is vergelyk met die habitattransformasiekaart wat bevolkte gebiede toon.

Evaluation tools, we adopted the methodological procedures of Strategic Environmental Assessment (SEA) proposed by the Ministry of the Environment, by this permit analysis of broad and systemic action policies-Plans-Programs (PPP) over a particular region or sector focus. Their evaluation stages comprise the phases described below: Screening, whose function consisted in the exhibition of the plan, through the confirmation of the possibility and necessity to apply the SEA management plan ecological corridor, under plan to be inserted into a region of great importance to biodiversity conservation, and because it is an action of significant regional intervention. The degree conferred strategy in this case in a regional plan for land management, where its operations mainly comprises the mosaic of protected areas and communities under the influence of the region. Exposed were the main driving forces that influence the impacts to the environment, characterized by agricultural activities, the expansion of the urban population due to land concentration and rural exodus, development projects for the transportation logistics and power generation, and pressure for reform agrarian. The following stage consisted of the definition of Scoping, whose initial function ended up exposing the intention of the ecological corridor management plan Araguaia-Bananal, in its goals identification, which later confirmed to be compatible with the sustainable development goals praised by the Brazilian AGENDA 21. In the politics-plans–programs (PPP) identification, those that apply influence towards performance forces in the ecological corridor region had been chosen, whose goals had passed by the compatibility evaluation with the management plan goals, verifying itself the diverse conflicting points evaluation, in special to those that stimulate the farming development and the infrastructure sector. The main indicators of sustaintability and production had been established, totalizing 40 indicators, that had assisted the ambient evaluation process, where the adopted procedure used the causal flow DPSIR model, allowing simultaneously to identify the 7 driving forces performance and 71 environment impacts. The conclusion obtained by this study indicates to a management plan that has goals and actions that would be effective in its application, if the indicators surveyed and their scenarios, it pointed to a reality unfavorable expressed by the low level of socioeconomic development of the region and lack of connectivity in the actions of the public sphere, leading to the individualization of responsibility in solving the problems of social and environmental agenda.

Повний текст джерелаUrbanization is one of major phenomena that impact biodiversity in the world. Numerous constraints associated with urban environment (habitat loss, changes in resources, chemical, light and noise pollutions, etc.) modify wildlife diversity and species distribution, and can have detrimental consequences on individuals. However, constant development of urbanization implies to update studies on the effects of urban environment on animal species, and particularly on birds, as they fulfill numerous ecosystem services for humans. In that context, we studied the benefits and costs of urban life for birds, working at three different levels: biodiversity, population and individual. First, we realized a spatial study on avian biodiversity in Niort (France). We highlighted the need to maintain green and connected infrastructures in cities, to favor common species as less adapted species to urban environment. Second, we evaluated the population state of house sparrows in cities, as they are strongly declining in large European cities. With the use of a correlative study, we showed that urban environment is very stressful for developing sparrows. Moreover, the analysis of osmotic stress in experimental conditions allowed to find that adult sparrows are also sensitive to changes of environmental conditions. Third, the application of a constraint of urban environment (light pollution) on house sparrows during reproduction revealed rapid changes in individual behavior in response to this constraint. Finally, results of these different approaches show that the effects of urbanization on birds are complex, and that demographic surveys need to be coupled with precise studies of urban habitat and associated constraints to better understand the evolution of bird populations in cities

Повний текст джерелаThe human pressures on natural environments generate fragmentation and loss of habitat, one of the main threats to biodiversity. Using the terrestrial mammals as indicators, it were evaluated the ecological corridor Embrapa- Fazenda Engenho Velho (Old Mill Farm) and a silvopastoral system to determine if they actually mitigate the negative impacts of local farming. Four linear transects were laid in two fragments of semideciduous forest in the ecological corridor that connects them and made 24 observations, including the branch tunnels (one with 0.9 m in diameter and another with 2.5 x2m) under the highway Guilherme Scatena (that divides the ecological corridor) and its coasting. With the data was constructed a dendrogram of similarity (Jaccard coefficient). In the silvopastoral system and conventional grazing, were placed four cages (15x15x40cm) in each and 20 observations were made. The results demonstrate the presence of 27 species in the fragments, seven of which use the corridor and only two uses the tunnel passage. The similarity between the fragments is high (65%), but decays over the corridor (44%) and the tunnel passage (19%), which shows that the ecological corridor is not fulfilling its role of facilitating the exchange of individuals among the fragments for greater genetic variability in local populations. Furthermore, the coasting had 11 species (45% similarity with fragments), but no individual was found run over, suggesting that in this case, the speed bumps installed on the highway are the most effective tools for conservation than the actual tunnel passage. The largest tunnel presented seven species, but lacks the vegetation in the surroundings unlike smaller tunnel, suggesting that for the branch tunnels, it is extremely important to their size. In the silvopastoral system were found four individuals from three genera (Calomys, Akodon and Oligorizomys) and in the common grazing, eight individuals of the genus Calomys, suggesting that silvopastoral systems are better to maintain species richness. We conclude that there are viable alternatives to improve production and maintain biodiversity, native vegetation with the best connection, but the deployments must be accomplished effectively and not only for law enforcement, without ever having a monitoring of its function, as occurs in most rural areas of the country subjected to this type of activity. Also we can t think that the mere fact of clearing vegetation and deploy these systems are solutions to the environmental crisis, but to optimize the use of land already cleared for such deployment.
As pressões antrópicas geram fragmentação nos ambientes naturais e consequente perda de habitat, uma das principais ameaças à biodiversidade. Utilizando a mastofauna terrestre como indicadores, foram avaliados o corredor ecológico Embrapa-Fazenda Engenho Velho e um sistema silvipastoril, para detectar se realmente mitigam os impactos negativos da agropecuária local. Foram dispostos quatro transectos lineares em dois fragmentos de floresta estacional semidecídua, no corredor ecológico que os conecta e feitas 24 observações, incluindo nos túneis de passagem (um de 0,9m de diâmetro e outro de 2,5x2m) sob a rodovia Guilherme Scatena (divide o corredor ecológico) e seu acostamento. Com os dados construiuse um dendrograma de similaridade (coeficiente de Jaccard). No sistema silvipastoril e em pastagem convencional foram dispostas quatro gaiolas (15x15x40cm) cada e foram feitas 20 observações. Os resultados demonstram a presença de 27 espécies nos fragmentos, das quais sete usam o corredor e somente duas o túnel de passagem. A similaridade entre os fragmentos é alta (65%), mas decai em relação os corredor (44%) e ao túnel de passagem (19%), o que demonstra que o corredor ecológico não está cumprindo seu papel de facilitar a permuta de indivíduos entre os fragmentos para que haja maior variabilidade genética nas populações locais. Além disso, o acostamento apresentou 11 espécies (45% de similaridade com os fragmentos), mas nenhum indivíduo foi encontrado atropelado, sugerindo que, neste caso, os redutores de velocidade instalados na rodovia são ferramentas mais eficazes para conservação do que o próprio túnel de passagem. O túnel maior apresentou sete espécies, mas não possui a vegetação no entorno como o túnel menor possui, sugerindo que, para túneis de passagem, é extremamente importante o seu tamanho. No sistema silvipastoril foram encontrados quatro indivíduos de três gêneros (Calomys, Akodon e Oligorizomys) e na pastagem comum, oito indivíduos do gênero Calomys, sugerindo que sistemas silvipastoris mantêm melhor a riqueza de espécies. Conclui-se que há alternativas viáveis para melhorar a produção e manter a biodiversidade, com a vegetação nativa melhor conectada, porém as implantações devem ser efetuadas de modo efetivo e não apenas para o cumprimento das leis, sem sequer haver um monitoramento de sua função, como ocorre na maioria das áreas rurais do país submetidas a esse tipo de atividade. Também não se deve pensar que o simples fato de desmatar e implantar esses sistemas são soluções para a crise ambiental, mas sim otimizar o uso de terras já desmatadas para tal implantação.
