Guidelines for planning genomic assessment and monitoring of locally adaptive variation to inform species conservation

Abstract Identifying and monitoring locally adaptive genetic variation can have direct utility for conserving species at risk, especially when management may include actions such as translocations restoration, rescue, or assisted gene flow. However, genomic studies of local adaptation require careful planning to be successful, in some cases not a worthwhile use resources. Here, we offer an framework help conservation biologists managers decide genomics is likely effective detecting adaptation, how plan assessment address objectives. Studies using tools will inform many cases, including applications flow identifying units. In others, assessing diversity, inbreeding, demographics selectively neutral markers most useful. And assessed more efficiently alternative approaches common garden experiments. identify key considerations variation, provide road map successful collaborations with experts issues study design data analysis, guidelines interpreting results from assessments programs actions.

Warm-water coral reefs and climate change

Science, Journal Year: 2015, Volume and Issue: 350(6262), P. 769 - 771

Published: Nov. 12, 2015

Coral reefs are highly dynamic ecosystems that regularly exposed to natural perturbations. Human activities have increased the range, intensity, and frequency of disturbance reefs. Threats such as overfishing pollution being compounded by climate change, notably warming ocean acidification. Elevated temperatures driving increasingly frequent bleaching events can lead loss both coral cover reef structural complexity. There remains considerable variability in distribution threats ability survive or recover from disturbances. Without significant emissions reductions, however, future is bleak.

Marine Environmental Epigenetics

Annual Review of Marine Science, Journal Year: 2018, Volume and Issue: 11(1), P. 335 - 368

Published: June 29, 2018

Marine organisms’ persistence hinges on the capacity for acclimatization and adaptation to myriad of interacting environmental stressors associated with global climate change. In this context, epigenetics—mechanisms that facilitate phenotypic variation through genotype–environment interactions—are great interest ecologically evolutionarily. Our comprehensive review marine epigenetics guides our recommendations four key areas future research: dynamics wash-in wash-out epigenetic effects, mechanistic understanding interplay different marks interaction microbiome, mechanisms transgenerational inheritance, evolutionary implications genetic features. Emerging insights in can be applied critical issues such as aquaculture, biomonitoring, biological invasions, thereby improving ability explain predict responses taxa

Population genetics of the coral Acropora millepora : Toward genomic prediction of bleaching

Science, Journal Year: 2020, Volume and Issue: 369(6501)

Published: July 17, 2020

Conservation help from genomics Corals worldwide are under threat rising sea temperatures and pollution. One response to heat stress is coral bleaching—the loss of photosynthetic endosymbionts that provide energy for the coral. Fuller et al. present a high-resolution genome Acropora millepora (see Perspective by Bay Guerrero). They were able perform population genetic analyses with samples sequenced at lower coverage conduct genome-wide association studies. These data combined generate polygenic risk score bleaching can be used in conservation. Science this issue p. eaba4674 ; see also 249

Adapting with Microbial Help: Microbiome Flexibility Facilitates Rapid Responses to Environmental Change

BioEssays, Journal Year: 2020, Volume and Issue: 42(7)

Published: June 16, 2020

Abstract Animals and plants are metaorganisms associate with microbes that affect their physiology, stress tolerance, fitness. Here the hypothesis alteration of microbiome may constitute a fast‐response mechanism to environmental change is examined. This supported by recent reciprocal transplant experiments reef corals, which have shown adapts thermally variable habitats changes over time when transplanted into different environments. Further, inoculation corals beneficial bacteria increases tolerance. But differ in ability flexibly bacteria. How scales flexibility reflect metaorganism adaptation mechanisms discussed future directions for research pinpointed. It posited broad phenomenon contributes organisms respond change. Importantly, adapting microbial help provide an alternate route organismal facilitates rapid responses.
