Regulation is required to mitigate the high cumulative propagule pressure exerted by escaped pet parrots

Margaret Stanley, Ellery McNaughton, Rachel Fewster and Josie Galbraith talk us through their recent research that uses reports of lost pet birds to estimate the cumulative propagule pressure that the pet trade exerts on the establishment of introduced bird species. Although concerns about the billion-dollar global pet trade industry have usually focused on issues associated with the trade of endangered species, the pet trade also … Continue reading Regulation is required to mitigate the high cumulative propagule pressure exerted by escaped pet parrots

Counting the ghosts of the mountains: sampling snow leopard populations at large spatial scales

Effective management of large carnivores requires robust monitoring at all scales. In their latest research, Manvi Sharma and colleagues describe the first systematic effort at estimating snow leopard populations at a large regional scale. The high-altitude mountains of the Himalaya are important habitats for unique flora and fauna adapted to these regions. The most charming of these species that has taken home here is the … Continue reading Counting the ghosts of the mountains: sampling snow leopard populations at large spatial scales

Bee abundance estimates vary by collection method and flowering richness

Monitoring bee populations is becoming increasingly important and commonplace, but do current methods produce reliable estimates of bee communities? Authors Marirose Kuhlman and Philip Hahn explore this question in their latest research. Wild bees are the main pollinators in nearly all terrestrial ecosystems and are essential to the reproductive cycles of many native plants, agricultural crops, and to the success of habitat restoration projects. Because … Continue reading Bee abundance estimates vary by collection method and flowering richness

Targeting survey and monitoring efforts on roads could help us better understand population changes in introduced carnivores

Carnivores usually occur over large areas in low numbers, which sometimes makes them difficult to find. In their recently published article, Hayley Geyle and colleagues assessed the effectiveness of different camera trap survey designs for detecting feral cats and red foxes, and looked at how this influenced their ability to determine whether populations had changed in response to control through time. Introduced carnivores in Australia … Continue reading Targeting survey and monitoring efforts on roads could help us better understand population changes in introduced carnivores
