Climate change can move the spatial location of resources critical for population viability, and a species resilience to such changes will depend upon its ability to flexibly shift its activities away from no-longer-suitable sites to exploit new opportunities. Intuition suggests that vagile predators should be able to track spatial shifts in prey availability, but our data on water pythons (Liasis fuscus) in tropical Australia suggest a less encouraging scenario. These pythons undergo regular long-range (to .10 km) seasonal migrations to follow flooding-induced migrations by their prey (native dusky rats, Rattus colletti ). However, when an extreme flooding event virtually eliminated …

Climate change modelers predict increasingly frequent ''extreme events,'' so it is critical to quantify whether organismal responses (such as reproductive output) measured over the range of usual climatic conditions can predict responses under more extreme conditions. In a 20-year field study on water pythons (Liasis fuscus), we quantified the effects of climatically driven annual variation in food supply on demographic traits of female pythons (feeding rate, body size, body mass, and reproductive output). Reaction norms linking food supply to feeding rates and residual body mass were broadly linear, whereas norms linking food supply to female body size became curvilinear when …

Corporate Discourse On Climate Change, Sharon Beder
Corporate Discourse On Climate Change, Sharon Beder

Corporations seek to manage democracies to suit their own interests through the exercise of persuasion, propaganda, political influence and financial power. This is particularly evident when corporate interests conflict with the public interest, as is the case with environmental protection. Effective government measures to avoid global warming have been thwarted for three decades as a result of corporate efforts. Corporations have sought to undermine public pressure for government action by casting doubt on global warming predictions by funding and promoting dissident scientists, front groups and think tanks. They have diverted blame from themselves in industry-sponsored educational materials. They have ensured …
