Planning for Climate Change Impacts on Geoheritage Interests in Protected and Conserved AreasNARA Subscribed
Climate change presents challenges for the management of geoheritage at all scales from individual geosites to whole landscapes, and affecting all areas of the planet. Direct impacts will arise principally through the effects of climate changes on geomorphological processes and vegetation cover, while indirect impacts will result from hard engineering interventions to mitigate risks from natural hazards. We present an indicati...
Seabirds often engage in coordinated, cooperative foraging to improve detection and capture of prey. An extreme example of such coordinated behavior is synchronicity, whereby the movements of individuals are aligned temporally and spatially. Synchronous diving among penguins has been reported, but simultaneous observations of predation by synchronously diving individuals have not. We instrumented chinstrap penguins ( Pygosceli...
Assessing the sensitivity of habitats to fishing: from seabed maps to sensitivity maps aNARA Subscribed
In the Welsh part of the Irish Sea, a method was developed for assessing the sensitivity of different seabed habitats to existing fishing activities, across a range of potential fishing intensities. The resistance of 31 habitats and their associated biological assemblage to damage by 14 categories of fishing activity were assessed along with the rate at which each habitat would recover following impact (resilience). Sensitivit...
We developed microsatellite markers and combined them with mitochondrial markers to analyse the population genetic structure of the queenless ant Diacamma indicum . This species, lacking winged queens, is likely to have a restricted female dispersal but exhibits various life history traits suggesting higher dispersal abilities than the other Diacamma species. Only 4 of 11 microsatellites were polymorphic and only 1 had more th...
