| Adaptive governance is an emergent form of environmental governance that is increasingly called upon by scholars and practitioners to coordinate resource management regimes in the face of the complexity and uncertainty associated with rapid environmental change. Although the term “adaptive governance” is not exclusively applied to the governance of social-ecological systems, related research represents a significant outgrowth of literature on resilience, social-ecological systems, and environmental governance. We present a chronology of major scholarship on adaptive governance, synthesizing efforts to define the concept and identifying the array of governance concepts associated with transformation toward adaptive governance.

| Historicamente, a modificação de ambientes naturais pelas atividades humanas tem causado grandes impactos sobre a vida selvagem que originalmente ocupavam estas paisagens. Por outro lado, muitas áreas consideradas de grande valor para a conservação da biodiversidade estão inseridas em um mosaico de fragmentos de remanescentes naturais intercalados em uma matriz predominantemente constituída por áreas agrícolas, onde muitas espécies da fauna silvestre encontram recursos necessários para sua sobrevivência enquanto outras não conseguem adaptar-se e acabam sofrendo ameaças até serem regionalmente extintas. |

| We present a Dynamic Energy Budget (DEB) model for the quintessential keystone predator, the rocky-intertidal sea star Pisaster ochraceus. Based on first principles, DEB theory is used to illuminate underlying physiological processes (maintenance, growth, development, and reproduction), thus providing a framework to predict individual-level responses to environmental change. We parameterized the model for P. ochraceus using both data from the literature and experiments conducted specifically for the DEB framework. We devoted special attention to the model's capacity to (1) describe growth trajectories at different life-stages, including pelagic larval and post-metamorphic phases, (2) simulate shrinkage when prey availability is insufficient to meet... |

| To better understand the effect of Paralytic Shellfish Toxins (PSTs) accumulation in the digestive gland of the Pacific oyster, Crassostrea gigas, we experimentally exposed individual oysters for 48 h to a PSTs producer, the dinoflagellate Alexandrium catenella. In comparison to the effect of the non-toxic Alexandrium tamarense, on the eight apoptotic related genes tested, Bax and BI.1 were significantly upregulated in oysters exposed 48 h to A. catenella. Among the five detoxification related genes tested, the expression of cytochrome P450 (CYP1A) was shown to be correlated with toxin concentration in the digestive gland of oysters exposed to the toxic dinoflagellate. Beside this, we observed a significant increase in ROS production, a decrease in... |

| A recent focusing event involving the death of a moose in the Dome open-pit mine in the community of Timmins, in northern Ontario, Canada has triggered the opening of a policy window related to the governance of resource extraction by indigenous peoples. This event, combined with several other factors, including: (1) the high price of gold; (2) a mining company seeking to demonstrate corporate social responsibility to repair its international reputation with indigenous peoples by supporting an innovative, local Indigenous-led initiative; and (3) a new policy context, including Supreme Court of Canada decisions and provisions in the updated Ontario Mining Act, that require meaningful consultation with indigenous peoples has led to the emergence of a... |
