Acclimate
The terms acclimatization and adaptation are often used synonymously but are not the same thing. Acclimatization refers to physiological changes whereas adaptation refers to genetic changes. Acclimatization
  • Changes occurring within the lifetime of an individual organism
  • Changes that result from chronic exposure to an environmental change and help an individual survive in a given environment. Such changes cannot be transmitted to offspring.
Adaptation
  • Changes occurring over generations within a species
  • Changes that provide an enhanced ability to survive and reproduce in a particular environment
Acclimatize
Acclimatization refers to phenotypic changes by an organism to stresses in the natural environment that result in the readjustment of the organism’s tolerance.
Adaptive Capacity Example
For example, people with low adaptive capacity may have a harder time adapting to climate change.
Agent
The term disease causative agent usually refers to a living, biological organism that causes a disease.
Aragonite
Aragonite is a mineral form of calcium carbonate (CaCO3) that is often used by marine species to form skeletons and shells.
Areas
Examples of areas more resistant or resilient to climate change include:
  • ecosystems that have resisted or recovered from damage (e.g. coral bleaching) in the past
  • reefs where thermal history and projections indicate lack of exceedence of coral bleaching thresholds
  • mangroves that have space to move inland with rising sea levels
  • ecosystems that have characteristics that indicate they are more likely to survive impacts in the future (e.g. heat-tolerant corals or reefs where thermal variability is high because they may be more resistant to bleaching)

Autotrophic
Autotrophic organisms are organisms (e.g., plants, algae) that make their own food from their surroundings, such as through photosynthesis.
Batis
Batis is a genus of flowering, salt-tolerant plants.
Bioerosion
In a coral reef context, bioerosion refers to the breakdown of calcareous material from the reef by biological processes.
Biofouling
Biofouling is the the accumulation of microorganisms, plants, algae, or animals on submerged surfaces. Biofouling communities commonly include barnacles, mussels, encrusting mollusks, bryozoans, tube worms.
Biogeographic
Biogeographic refers to the distribution of biodiversity over space. A biogeographic region is a geographic area with similar dominant plants, organisms and prevailing climate conditions.
Biotic
Relating to, produced by, or caused by living organisms
BOFFF
BOFFF is the abbreviation for Big Old Fat Fertile Female. Bofffs are more biologically valuable due to their age and reproductive abilities, and removing them from the system is more detrimental than removing younger, non-reproductive fish.
Catch Quota
A tool often employed by managers of large commercial fisheries, intended to conserve the resource. A total allowable catch limit is set for a fishing season, and when fishers reach this quota, the fishery is closed. This method can produce a negative effect on the resource as fishers “race” to meet the quota, often using wasteful or destructive methods to extract as many fish as quickly as possible. Intensive monitoring and enforcement is required.
Catch-per-unit-effort (CPUE)
Definition: The quantity of fish caught (in number or in weight) with a specific unit of fishing effort.

Co-management
Co-management is a process by which institutional arrangements and ecological knowledge are tested and revised in a dynamic, ongoing self-organized process of learning-by-doing (Folke et al. 2002). Through this process, different resource management bodies collaborate in order to reach a shared goal of managing resources.
Colony Integration
The degree of colony unity with respect to behavior, physiology, and development of individual organs or organ complexes within colonies. Characteristics of colony integration include polyp dimorphism, intra-tentacular budding and complex colony morphology. Species with high colony integration are predicted to result in a greater whole-colony response to increased temperatures than species with low colony integration.
Compensatory Mitigation
In the U.S., mitigation is essentially a three-part process. If a proposed project will impact marine resources, federal agencies first attempt to modify the proposed project to avoid impacts. If after all avoidance measures have been implemented and project-related impacts still exist, federal agencies then attempt to minimize impacts. Finally, if unavoidable impacts still exist after all attempts at avoidance and minimization, the federal agencies must replace the resource’s lost functions through compensatory mitigation (see pdf, 1.2M).
Cryptic
Hidden or difficult to see
Degree Heating Weeks
Degree Heating Weeks is a combination of temperature anomalies and duration of exposure to quantify the accumulated thermal stress in a particular region. One DHW is equivalent to one week of sea surface temperature one degree Celsius warmer than the expected summer-time maximum.
Demographic Connectivity
Connectivity is much more than the biophysical coupling of larvae from reproductive populations to recruitment sites. To sustain and grow, populations require an unbroken nexus among reproductive populations called demographic connectivity (Steneck et al. 2009).
Diver Carrying Capacity
This concept is based on a study in Bonaire that found that sites with high dive use had lower coral percent cover, whereas sites with low dive use had higher species diversity. Based on these findings, the authors developed a threshold for dive use per year.
Echinoderms
A phylum of marine animals usually recognized by radial symmetry; includes sea stars and sea urchins
Ecological targets
Ecological targets include natural resources and ecological services.
Economic Assets
Economic assets include property, infrastructure, and income.
Ecoregion
An ecoregion is an area that contains a distinct assemblage of communities and species. The composition of an ecoregion is influenced by several small ecosystems and/or distinct oceanographic or topographic features including isolation, upwelling, nutrient inputs, freshwater, temperature regimes, ice regimes, sediments, currents, bathymetric or coastal complexity. (For example, within Central Polynesia, there are 3 ecoregions: Line Islands, Phoenix/Tokelau/Northern Cook Islands and Samoa Islands). Ecoregions can be used as planning units for marine conservation.
Ecosystem Resilience
Ecosystem resilience refers to the ability of an ecosystem to maintain key functions and processes in the face of stresses or pressures by either resisting or adapting to change.
Ecosystem Services
Definition: The benefits people obtain from ecosystems. These include provisioning services, such as food and water; regulating services, such as flood and disease control; cultural services, such as spiritual and cultural benefits; and supporting services, such as nutrient cycling, that maintain the conditions for life on Earth.
Explanation: All the tangible and intangible benefits provided to people by ecosystems. There are four big groups of ecosystem services: (1) provisioning services, which refer to the products offered by an ecosystem, such as food, raw materials, water, minerals, medicinal resources, energy; (2) supporting services, since ecosystems provide all that is necessary for individual plants and animals to survive; (3) regulating service, such as decomposition, climate regulation, water and air purification, erosion control; and (4) cultural services, as ecosystems or parts of ecosystems can have spiritual or religious meaning for a given community, or they can have a positive impact on health, or function as inspiration for art and contemplation.

Ecosystem-based Adaptation
The use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people adapt to the adverse effects of climate change
Effort Creep
Definition: A slow increase in fishing effort and capacity as fishers substitute from regulated to unregulated inputs. An example of effort creep could be described by attempting to limit effort through vessel licenses, only to have the licensed vessels increase fishing effort by switching to larger boats, adding extra or more efficient gear, etc.
Explanation: Effort creep refers to situations where fishing inputs, or the various components of fishing effort such as use of gear, vessel use, and fishing time, gradually increase, thereby also increasing fish exploitation.

Source: Empirical Data in The American Heritage Dictionary of the English Language, 5th edition. Pickett JP (ed). 2011.
Energy Regime
Energy regime refers to the level of energy that characterizes a location. For example, a site on the leeward side of an island would have a lower energy regime because the influence of the wind on a daily basis is minimal.
Epilithic
Epilithic algal turf refers to a diverse assemblage of crustose coralline algae and turf algae growing upon limestone. Turf algae refers to the multispecific and inconspicuous association of unicellular, and short (usually < 1 cm high), simple filamentous algae.
Eutrophication
Eutrophication is the natural or artificial (e.g., from fertilizer runoff or sewage discharge) addition of nutrients into bodies of water that often encourages excessive algal growth.
Exposure
Exposure describes the level of being exposed to physical forces such as high wave energy, wind, and strong currents. If an area is surrounded by islands with limited influence from waves, wind, and currents, its level of exposure is minimal.
Exposure Example

Source: NOAA Fisheries Glossary. Blackhart K, Stanton DG, and  Shimada AM. 2006. US Department of Commerce, National Oceanic and Atmospheric Administration. 
Fully Exploited
Fish stocks produce catches close to their maximum sustainable production, thus have no room for expansion and require management to avoid decline.
Fully Exploited
Definition: When relating to a fishery, this means that the fishery is operating at or close to an optimal yield level, with no expected room for further expansion. SourceOcean Health Index: Stock Exploitation Status.
Funcional Redundancy
Functional redundancy refers to species that can assume the role of others so the loss of one species is potentially compensated for by the actions of another.
Functional Group
A collection of species that perform a similar function, regardless of their taxonomic group (Steneck and Dethier 1994). For example, corals form an important functional group that provides three-dimensional habitats for fishes and other organisms and contributes to reef growth. Herbivores constitute another functional group that plays a key role in controlling algal growth, thereby helping to enhance coral recruitment, recovery, and therefore resilience.
Gleaning
Definition: Walking along the intertidal zone at low tide and collecting resources, usually edible invertebrates and fish.

GPS
GPS stands for global positioning system. It typically consists of a handheld or mounted electronic unit that receives signals from GPS satellites to determine its exact position on the earth in terms of latitude and longitude. The unit can also record and store your position, which is called a waypoint. This allows you to return to exactly the same location later or create a route map of where you have been when multiple waypoints are entered. Used in conjunction with a depth sounder, a GPS can help you map the bathymetry of the seafloor.
Greywater
Wastewater generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled for other uses (e.g., landscape irrigation and constructed wetlands). It does not include water which contains human waste, such as from toilets.
Ground Truth
Ground truth survey refers to information that is collected “on location.”
Harvest Control Rules
Definition: Harvest control rules are well-defined rules that help determine annual fish catch quotas and/ or effort. They describe how harvest is intended to be controlled by management in relation to the state of some indicator of stock status. For example, a harvest control rule can describe the various values of fishing mortality that will be aimed at for various values of the stock abundance.

Institutional Capacity
DefinitionThe ability, will, and skills of an institution to initiate, plan, manage, undertake, organize, budget, monitor/supervise, and evaluate project activities. Explanation: Institutional capacity refers to the ability of an organization or institution to perform certain functions, solve problems and set and achieve objectives. The capacity of an institution or organization is dependent on a clear mission and on its ability to employ appropriate resources and management practices for achieving its mission. For actions carried out at a regional or national level, institutional capacity also involves the cooperation of many different institutions and organizations, for example ministries, agencies, central and regional or local governments, private organizations, businesses or other non-governmental organizations. Such networking capacity relies on communication and coordination with key actors, on the establishment and implementation of procedures and financial provisions for the network, on allocation of responsibilities, and on ensuring the stability of the network.

Intervention
An intervention is any action or set of actions deliberately taken to improve the functioning of the group.
Intra-tentacular
Intra-tentacular budding is a method of growth for corals. In this form, coral polyps divide by simple fission and each bud retains part of the original polyp.
Larval Duration
Pelagic larval duration refers to the amount of time the larvae spend in the open ocean before settlement on the reef.
Latent Effort
Definition: The available but unused opportunity for fishing vessels to participate in a fishery. An example of latent effort would be allocated fishing permits for a vessel for a specific number of fishing days that go unused.
Explanation: Latent effort refers to the available, but unused option for vessels to participate in fishery activities. If latent effort is included in calculating fishing effort, but subsequently not used, the fishery may underperform.

Logarithmic
A logarithmic scale is a scale of measurement that displays the value of a quantity using intervals corresponding to orders of magnitude, rather than a standard linear scale. For example, a chart with a vertical axis with equally spaced increments labeled 1, 10, 100, 1000, instead of 1, 2, 3, 4. Each unit increase on the logarithmic scale represents an exponential increase in the underlying quantity for the given base (10, in this example).
Management Response Framework

Management Tools
Definition: The tools adopted by the management authority to reach established management goals. In addition to the objectives, it includes choices regarding all or some of the following: access rights and allocation of resources to stakeholders, controls on inputs (e.g., fishing capacity, gear regulations), outputs (e.g., quotas, minimum size at landing), and fishing operations (e.g., calendar, closed areas, and seasons).

Overexploited
DefinitionThe fishery is being exploited, or harvested, above a level that is believed to be sustainable in the long term, with no potential room for further expansion and a higher risk of stock depletion and/or collapse.
Explanation: A species or a fishery is overexploited when it is harvested faster than it can recover, for example through overfishing. If the situation continues beyond a critical point, it can lead to the destruction of the affected species. SourceOcean Health Index: Stock Exploitation Status.
PAR

Proxy indicators
DefinitionA variable used to stand in for one that is difficult to measure directly. Explanation: A proxy indicator is an indirect measure for a phenomenon which cannot be measured by direct means. For example, the economic performance of a fishery can be measured by proxy indicators such as whether income is high enough to allow for gear upkeep, whilst data on Catch Per Unit Effort (CPUE) can be used as indirect information on resource abundance. Source: Handbook on Planning, Monitoring and Evaluating for Development Results. UNDP Evaluation Office. 2002. 
Recruitment Success
Recruitment success refers to the number of fish larvae per amount of spawning fish biomass that successfully establish themselves on a reef and contribute as individuals to the fish population. Because most reef fishes release their eggs into the pelagic environment, the larvae are subjected to a number of factors such as: oceanographic currents, tides, food availability, and predation. These factors are wide-ranging and variable, and therefore the number of larvae that can successfully recruit back to a reef may differ significantly from year to year and even longer time frames.
Refugia
Refugia are secure areas that are protected by natural factors and/or human intervention from a variety of stresses. They are meant to function as reliable sources of seed over time.
Rehabilitation
The act of partially or fully replacing structural or functional characteristics of an ecosystem that have been diminished or lost, or the substitution of alternative qualities or characteristics than those originally present, with the provision that they have more social, economic or ecological value than existed in the disturbed or degraded state.
Relict
An organism that at an earlier time was abundant in a large area but now occurs at only one or a few small areas.
Remediation
The act or process of remedying or repairing damage to an ecosystem.
Resilience
Definition: Resilience is the capacity of a system to respond to and absorb disturbance while retaining essentially the same function, structure, and feedbacks; it has been defined for both ecosystems and social systems.   Explanation: Resilience is the ability to adapt to or recover from the impact of external factors such as stress, difficulties, shocks, or disasters. A resilient ecosystem can tolerate disturbances without fundamentally changing its structure and processes. In the case of fisheries, resilience can be affected by weather events such as hurricanes, by pathogens or other biological factors, by human activity such as over-fishing and pollution.

Resistance
Resistance to bleaching is exhibited when coral colonies do not bleach, or bleach but don’t die. Resistance may vary among different parts of a reef and between different reef communities.
Restoration
The process of re-establishing, following degradation by human activities, a sustainable habitat or ecosystem with natural structure and functioning. Restoration can accelerate recovery although this could lead to an alternative state
