Stressor fluctuations alter mechanisms underpinning seagrass responses to multiple stressors.

Multiple anthropogenic stressors degrade ecosystems globally. A key knowledge gap in multiple stressor research is how variability in stressor intensity (i.e.

Stressor fluctuations alter mechanisms of seagrass community responses relative to static stressors.

Ecosystems are increasingly affected by multiple anthropogenic stressors that contribute to habitat degradation and loss. Natural ecosystems are highly dynamic, yet multiple stressor experiments often ignore variability in stressor intensity and do not consider how effects could be mediated across trophic levels, with implications for models that underpin stressor management. Here, we investigated the in situ effects of changes in stressor intensity (i.

Greater Consideration of Animals Will Enhance Coastal Restoration Outcomes.

As efforts to restore coastal habitats accelerate, it is critical that investments are targeted to most effectively mitigate and reverse habitat loss and its impacts on biodiversity. One likely but largely overlooked impediment to effective restoration of habitat-forming organisms is failing to explicitly consider non-habitat-forming animals in restoration planning, implementation, and monitoring. These animals can greatly enhance or degrade ecosystem function, persistence, and resilience.

Fluctuating fortunes: Stressor synchronicity and fluctuating intensity influence biological impacts.

Ecosystems remain under enormous pressure from multiple anthropogenic stressors. Manipulative experiments evaluating stressor interactions and impacts mostly apply stressors under static conditions without considering how variable stressor intensity (i.e.

Evaluating multiple stressor research in coastal wetlands: A systematic review.

Multiple stressors are ubiquitous in coastal ecosystems as a result of increased human activity and development along coastlines. Accurately assessing multiple stressor effects is essential for predicting stressor impacts and informing management to efficiently and effectively mitigate potentially complex ecological responses. Extracting relevant information on multiple stressor studies conducted specifically within coastal wetlands is not possible from existing reviews, posing challenges in highlighting knowledge gaps and guiding future research.

Exogenous 20-hydroxyecdysone induces epidermal carbonic anhydrase but inhibits exoskeletal calcification in the post-ecdysial blue crab, Callinectes sapidus.

The crustacean exoskeleton is composed primarily of chitin, proteins and various inorganic compounds. It is the inorganic compounds, such as calcium and magnesium, that underlie the exoskeletal mineralization process following ecdysis. Little is known about the hormonal mechanism for this process in crustaceans.
