Using macroalgal bioindicators to map nutrient plumes from fish farms and other sources at a bay-wide scale (Page 1)

Using macroalgal bioindicators to map nutrient plumes from fish farms and other sources at a bay-wide scale

Human activities can elevate coastal levels of dissolved inorganic nitrogen (DIN). As macroalgae readily absorb and accumulate DIN, the elemental (total N and C:N ratio) composition of their tissues is less affected by temporal fluctuations compared to more direct measures of DIN concentration. Additionally, their isotopic (δ15N) composition can reflect that of the source, which could potentially be used to identify between multiple effluent sources.

Ecological Drought Across the United States

Profound, widespread, and becoming more severe

Carter S, Donahue K, Myers B, Rubenstein M, Dennison WC, Lentz R, Blackband J, Malpeli K, Costanzo S, and Walsh B ·
1 August 2019

Across the United States, ecological drought is ubiquitous, profound, and has become more severe. This newsletter summarizes the findings of a three-year synthesis on the current status of drought research across the United States. The ecological drought synthesis project involved workshops at each of the eight regional Climate Adaptation Science Centers.

Tuul River Basin Report Card 2019 (Page 1)

Tuul River Basin Report Card 2019

Simon Costanzo, Dylan Taillie ·
22 March 2019

The Tuul River Basin Report Card—the first of its kind in Mongolia—assesses the basin's health through social, environmental and economic values that can be tracked over time in response to management actions and/or external pressures. The Tuul River Basin has been evaluated in this assessment as “moderate” health or ‘C’, meaning urgent management interventions are required to maintain the health of the river.

Healthy Rivers for All

Brianne Walsh, Alexandra Fries, Simon Costanzo, Heath Kelsey, Bill Dennison ·
7 September 2018

The world’s waters are threatened by a host of problems. Impacts from human activities like development and overuse are exacerbated by changes in climate, and increased competition by different societal interests, putting vulnerable communities and ecosystems at risk. Creating a sustainable balance of water needs for both nature and people is challenging. It will require people that are competing for water resources to work together in new collaborations and partnerships.

Towards a framework to support coastal change governance in small islands (Page 1)

Towards a framework to support coastal change governance in small islands

Glaser M, Breckwoldt A, Carruthers T, Forbes DL, Costanzo S, Kelsey RH, Ramachandran R, and Stead S ·
2018

Small islands can guide visualization of the diverse information requirements of future context-relevant coastal governance. On small marine islands (<20 000 km2), negative effects of coastal challenges (e.g., related to population growth, unsustainable resource use or climate change) can develop rapidly, with high intensity and extreme impacts.
