2016 Maryland Coastal Bays Report Card

Alexandra Fries, Heath Kelsey, Bill Dennison ·
12 December 2017

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2016 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a , dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

Seagrass ecosystem trajectory depends on the relative timescales of T resistance, recovery and disturbance (Page 1)

Seagrass ecosystem trajectory depends on the relative timescales of T resistance, recovery and disturbance

O'Briena KR, Waycott M, Maxwell P, Kendrick GA, Udy JW, Ferguson A JP, Kilminster K, Scanes P, McKenzie LJ, McMahon K, Adams MP, Samper-Villarreal J, Collier C, Lyons M, Mumby PJ, Radke L, Christianen M JA, and Dennison WC ·

Seagrass ecosystems are inherently dynamic, responding to environmental change across a range of scales. Habitat requirements of seagrass are well defined, but less is known about their ability to resist disturbance. Specific means of recovery after loss are particularly difficult to quantify. Here we assess the resistance and recovery capacity of 12 seagrass genera.

Long-term nutrient reductions lead to the unprecedented recovery of a temperate coastal region (Page 1)

Long-term nutrient reductions lead to the unprecedented recovery of a temperate coastal region

Lefcheck JS, Orth RJ, Dennison WC, Wilcox DJ, Murphy RR, Keisman J, Gurbisz C, Hannam M, Landry JB, Moore KA, Patrick CJ, Testa J, Weller DE, and Batiuk RA ·
2017

Humans strongly impact the dynamics of coastal systems, yet surprisingly few studies mechanistically link management of anthropogenic stressors and successful restoration of nearshore habitats over large spatial and temporal scales. Such examples are sorely needed to ensure the success of ecosystem restoration efforts worldwide.
