Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Ecosystem restoration is a critical nature-based solution to mitigate climate change. However, the carbon sequestration potential of restoration, defined as the maximum achievable carbon storage, has likely been overestimated because previous studies have not adequately accounted for the competition between ecosystem water demands for maximizing carbon sequestration and human water needs. Here we used a comprehensive process-based model combined with extensive land-use data and evaporation recycling accounting for land–atmosphere feedback to estimate the water requirements associated with ecosystem restoration. We found that achieving the carbon sequestration potential of restoration would significantly reduce global water availability per capita by 26%, posing …

Student Publications

While some deleterious effects of road networks and the vehicles that travel them– such as pollution, fossil fuel extraction, and carbon emissions– are widely recognized, their significant role in causing an estimated one million wildlife deaths per day (Shilling et al., 2021) and contributing to habitat loss and degradation, the leading causes of global biodiversity decline (Pinto et al., 2023), has garnered less attention. Connective conservation policies, such as designating wildlife corridors and constructing wildlife crossings on roadways, have been proposed as a means of mitigating these repercussions. This study proposes a connective conservation plan addressing the logistics of a …

Feral Donkey, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Donkeys (Equus asinus) were first imported in substantial numbers to Australia in 1866 by Sir Thomas Elder. They were used as pack and draught animals in outlying areas of Western Australia (WA) until the 1930s. They were eventually replaced by the motor vehicle, and unwanted donkeys were released to the wild, where they became feral. The first record of feral donkeys is from the Kimberley in the early 1930s, but it is possible they became feral much earlier.

Intrinsic And Environmental Drivers Of Pairwise Cohesion In Wild Canis Social Groups, John F. Benson

School of Natural Resources: Faculty Publications

Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group-level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing cohesion remains a gap in our knowledge of cooperative behavior in animals. We tracked 574 individuals from six species within the genus Canis in 15 countries on four continents with GPS telemetry to estimate the time that pairs of individuals within …
