Connectivity conservation is a community-led approach to conservation that brings people together to reverse the impacts of habitat loss, fragmentation and degradation by reconnecting our natural world. Research clearly shows that the conventional approach of prioritising the conservation of isolated patches of habitat in national parks is insufficient by itself to ensure the long-term survival and adaptability of our wildlife and the resilience and integrity of our ecosystems – connectivity(the degree to which landscapes and seascapes allow species to move freely and ecological processes to function unimpeded) is crucial for our survival. 2, record 2, English, - connectivity%20conservation

Lorsqu'un habitat est morcelé en de petits «îlots» séparés les uns des autres, nous sommes en présence d'un phénomène appelé «fragmentation de l'habitat». [...] Ce morcellement représente un obstacle à la survie des espèces qui dépendent d'un type d'habitat particulier, parce qu'elles y sont confinées et qu'elles ne peuvent pas survivre ailleurs. 4, record 3, French, - fragmentation%20d%27habitat

Habitat fragmentation is the loss and subdivision of portion of a given habitat and the corresponding increase in other habitats in the landscape. It is one of the most important contributors to the loss of biological diversity in temperate regions. Because of fragmentation, large populations are being broken into local populations, and this can lead to extinction if the local populations cannot interact. 7, record 7, English, - biodiversity%20loss

La pérdida de biodiversidad es probablemente uno de los problemas científicos más importantes que tenemos que abordar en el Siglo XI. Bosques cortados y reducidos a su mínima extensión, transformaciones de tierras, cambios drásticos de usos del suelo, contaminación de suelos y aguas, sobreexplotación de recursos naturales, todo ello está llevando a la más grave extinción de biodiversidad que el hombre haya podido conocer a lo largo de su historia. Esta pérdida no sólo afecta a la vida silvestre (fauna y flora) sino a la diversidad genética cuyo ejemplo más cercano podemos encontrarlo en la desaparición de razas y variedades domésticas. 3, record 7, Spanish, - p%C3%A9rdida%20de%20biodiversidad

Deviations would include significant new human-caused mutations or gene combinations, loss of genes, pressures of habitat fragmentation, significant changes in gene frequency in a population or the extirpation of genetically unique populations. 1, record 16, English, - deviation

Normes de diversité génétique. Chaque espèce est unique et possède sa propre norme de diversité génétique, à tout moment de son évolution au sein de l'écosystème. Si on définissait une norme pour ce type de diversité, il devrait être possible de détecter et de mesurer les écarts qui existent par rapport à elle. Ces écarts comprendraient les nouvelles mutations et combinaisons géniques d'origine humaine, les pertes de gènes, les pressions résultant d'une fragmentation de l'habitat, les changements appréciables dans la fréquence d'un gène dans une population donnée et les disparitions de populations uniques sur le plan génétique. 1, record 16, French, - %C3%A9cart
