Resource managers have rarely accounted for evolutionary dynamics in the design or implementation of climate change adaptation strategies. We brought the research and management communities together to identify challenges and opportunities for applying evidence from evolutionary science to support on‐the‐ground actions intended to enhance species'...

This study assesses vulnerability to climate change and local adaption strategies in the Kribi-Campo coastal area. Variables of exposure, sensitivity and adaptive capacity are described and assessed based on the community's perception and biophysical evidence. Historical changes in rainfall and temperature variables, mangrove cover and occurrence o...

Gulf Coast communities and natural resources suffered extensive direct and indirect damage as a result of the largest accidental oil spill in US history, referred to as the Deepwater Horizon (DWH) oil spill. Notably, natural resources affected by this major spill include wetlands, coastal beaches and barrier islands, coastal and marine wildlife, se...

Worldwide, many species are responding to ongoing climate change with shifts in distribution, abundance, phenology, or behavior. Consequently, natural-resource managers face increasingly urgent conservation questions related to biodiversity loss, expansion of invasive species, and deteriorating ecosystem services. We argue that our ability to addre...

A National Academies of Sciences, Engineering, and Medicine committee was tasked with developing a strategy to increase the nation's scientific capability for research on sub-seasonal to seasonal prediction of weather and climate over the coming decade. The Committee's report (released in the fall of 2015) discusses the advancement of S2S predictio...

Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface...

Satellite measurements of ocean color provide a unique vantage point to measure global phytoplankton abundance and their contribution to the health of marine ecosystems, the global cycle of nutrients, oxygen, and carbon, and their response to long-term climate change. However, the United States is at risk of losing access to ocean color data becaus...

Satellite measurements of ocean color provide a unique global perspective on the health of marine ecosystems and their contribution to the global cycle of nutrients, oxygen, and carbon, as well as their response to long-term climate change. The nation is at risk of losing access to ocean color data because existing satellite sensors are aging and p...

At the request of Congress, the National Academy of Sciences convened a series of coordinated activities to provide advice on actions and strategies that the nation can take to respond to climate change. As part of this suite of activities, this study assessed, this study assessed how the nation can begin to adapt to the impacts of climate change....

U.S. National Academies' Board on Atmospheric Sciences and Climate (BASC) meeting Woods Hole, Mass., 8-9 August 2006 What constitutes an effective vision for a national weather enterprise? Can barriers to improving subseasonal weather and climate predictions be removed? What are ethical considerations surrounding possible geoengineering approaches...

We provide the first confirmation of the presence of domoic acid (DA) in phytoplankton and fish in San Diego, California, based on samples collected between 1 October 2003 and 29 September 2004. In February 2004, we detected DA in seawater samples collected off the Scripps Pier and also in coastal samples as far as 120 km to the north. At the same...

The present study compares the Ultraviolet A (UVA: 320 to 400 nm) enhancement of in situ carbon fixation relative to Ultraviolet B (UVB: 280 to 320 nm) inhibition for a community dominated by the diatom genus Pseudo-nitzschia with other mixed phytoplankton communities in the Santa Barbara Channel in June 1998. At the time, a widespread bloom of tox...

A study to explore the linkage between organic nitrogen loading and Pseudo-nitzschia spp. is presented. It is studied that increase in the domoic acid (DA) concentration, which has resulted mass mortality among dolphins, sea lions, and birds, has resulted in the blooms of toxicogenic microalgae Pseudo-nitzschia spp. It is also understood that the m...

In order to study the factors controlling the phytoplankton distribution across the Antarctic Polar Frontal Region (PFR), surface pigment samples were collected during austral summer (January/February 1998) near 170 degreesW. Both the Polar Front (PF) and the Southern Antarctic Circumpolar Current Front (SACCF) were regions of enhanced accumulation...

Intrusion of Upper Circumpolar Deep Water (UCDW), which was derived from the Antarctic Circumpolar Current (ACC), onto the western Antarctic Peninsula (WAP) shelf region in January 1993 provided a reservoir of nutrient-rich, warmer water below 150 m that subsequently upwelled into the upper water column. Four sites, at which topographically-induced...
