Balancing multiple management objectives as climate change transforms ecosystems.

As climate change facilitates significant and persistent ecological transformations, managing ecosystems according to historical baseline conditions may no longer be feasible. The Resist-Accept-Direct (RAD) framework can guide climate-informed management interventions, but in its current implementations RAD has not yet fully accounted for potential tradeoffs between multiple - sometimes incompatible - ecological and societal goals. Key scientific challenges for informing climate-adapted ecosystem management include (i) advancing our predictive understanding of transformations and their socioecological impacts under novel climate conditions, and (ii) incorporating uncertainty around trajectories of ecological change and the potential success of RAD interventions into management decisions.

Impacts of livestock grazing on the probability of burning in wildfires vary by region and vegetation type in California.

Wildfire activity has recently increased in California, impacting ecosystems and human well-being. California's rangelands are complex social-ecological systems composed of multiple ecosystems and the people who live and work in them. Livestock grazing has been proposed as a tool for reducing wildfire activity.

Expanding ocean food production under climate change.

As the human population and demand for food grow, the ocean will be called on to provide increasing amounts of seafood. Although fisheries reforms and advances in offshore aquaculture (hereafter 'mariculture') could increase production, the true future of seafood depends on human responses to climate change. Here we investigated whether coordinated reforms in fisheries and mariculture could increase seafood production per capita under climate change.

Sovereign states in the Caribbean have lower social-ecological vulnerability to coral bleaching than overseas territories.

Coral reef social-ecological systems worldwide face major impacts from climate change, and spatial variation in vulnerability is driven by differential exposure to climatic threats, ecological and socio-economic sensitivity to those threats, ecological recovery potential, and socio-economic adaptive capacity. We assess variation in social-ecological vulnerability to climate change-induced coral bleaching, specifically for reef-based fisheries and tourism, of islands throughout the insular Caribbean, thus providing the first region-wide quantitative analysis of island-scale social-ecological vulnerability to coral bleaching. We show that different components of vulnerability have distinct spatial patterns and that variability in overall vulnerability is driven more by socio-economic than ecological components.

Evaluating the dual target binding capabilities of immobilized aptamers using flow cytometry.

In the current study, the authors quantify the binding activity of particle-immobilized DNA aptamers to their nucleotide and non-nucleotide targets. For the purposes of this work, DNA and vascular endothelial growth factor (VEGF) binding analysis was carried out for VEGF-binding aptamers and compared to that of an ampicillin-binding aptamer as well as a non-aptamer DNA probe. Binding analysis followed incubation of one target type, coincubation of both DNA and VEGF targets, and serial incubations of each target type.
