Concept Definition Deliverable(s)
fishing

Fishing is defined as the removal from their habitats of aquatic animals (vertebrates and invertebrates) that spend their full life cycle in water (fish, some marine mammals, shellfish, shrimps, squids, corals). Fishing most often results in the death of the aquatic animal, but it may not in some cases. To reflect both situations, fishing has been sub-divided into a lethal and a “non-lethal” category. Lethal fishing is defined as the general and more usual meaning of fishing that leads to the killing of the animal, such as in traditional commercial fisheries. “Non-lethal fishing is defined as the temporary or permanent capture of live animals from their habitat without intended mortality, such as in aquarium fish trade or catch and release. However, unintended mortality may occur in “non-lethal” fishing and the term “non-lethal” is therefore put in quotes. The killing of species that spend part of their life cycle in terrestrial environments (e.g. walrus, sea turtles) is encompassed by the definition of hunting.

Sustainable use assessment
fitness (ecology)

Fitness involves the ability of organisms- or populations or species- to survive and reproduce in the environment in which they find themselves, and thus contribute genes to the next generation (Orr, 2009).

Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems.

Pollination assessment
food sovereignty (paradigm)

The right to define own policies and strategies for the sustainable production, distribution and consumption of food that guarantee the right to food for the entire population, on the basis of small and medium-sized production, respecting their own cultures and the diversity of peasant, fishing and indigenous forms of agricultural production, marketing and management of rural areas, in which women play a fundamental role.

Land degradation and restoration assessment

functional redundancy

The occurrence in the same ecosystem of species filling similar roles, which results in a sort of insurance in the ecosystem, with one species able to replace a similar species from the same functional niche.

Global assessment (1st work programme)
functional trait

A feature of an organism, which has demonstrable links to the organism's function (Lavorel et al. 1997). As such, a functional trait determines the organism's response to pressures (Response trait), and/or its effects on ecosystem processes orservices(Effect trait).Functional traits are considered as reflecting adaptations to variation in the physical and biotic environment and trade-offs (ecophysiological and/or evolutionary) among different functions within an organism. In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits, including demographic traits(at population level). In animals, these traits are combined with lifehistory and behavioural traits (e.g. guilds, organisms that use similar resources/ habitats).

Asia-Pacific assessment
functional trait

Any feature of an organism, expressed in the phenotype and measurable at the individual level, which has demonstrable links to the organism's function. As such, a functional trait determines the organism's response to external abiotic or biotic factors (response trait), and/or its effects on ecosystem properties or benefits or detriments derived from such properties (effect trait). In plants, functional traits include morphological, ecophysiological, biochemical and regeneration traits. In animals, these traits include e.g. body size, litter size, age of sexual maturity, nesting habitat, time of activity.

fungicide

A substance that kills or inhibits the growth and development of fungi. Fungicides may be synthetic chemicals, natural chemicals, or biological agents.

Pollination assessment
gathering

Gathering is defined as the removal of terrestrial and aquatic algae, fungi, and plants (other than trees) or parts thereof from their habitats. Gathering may, but often does not, result in the death of the organism. Gathering includes whole plant harvest and removal of above and/or below ground plant parts, as well as the fruiting bodies of macrofungi. It also includes removal of non-woody portions of trees (leaves, propagules, and bark). Where removal of propagules or death of an individual plant occurs (e.g. whole plant and root removal) effects on population sustainability are contingent upon factors including timing, frequency, and intensity of harvest. The harvest of wood and woody parts of trees is encompassed by the definition of logging.

Sustainable use assessment
gender

The term gender refers to the socially-constructed expectations about the characteristics, aptitudes and behaviors associated with being a woman or a man. Gender defines what is feminine and masculine. Gender shapes the social roles that mean and women play and the power relations between them, which can have a profound effect on the use and management of natural resources. Gender is not based on sex or the biological differences between women and men; rather, gender is shaped by culture and social norms. Thus, depending on values, norms, customs and laws, women and men in different parts of the world have adopted different gender roles and relations. Within the same society, gender roles also differ by race/ethnicity, class/caste, religion, ethnicity, age and economic circumstances. Gender and gender roles then affect the economic, political, social, and ecological opportunities and constraints faced by both women and men (Convention on Biological Diversity, 2017). The framing of sex and gender as binaries is in fact a cultural ideology. The empirical reality is that sex is a spectrum, manifesting in a wide array of sex variance. Some people don't neatly fit into the categories of man or woman, or “male” or “female.” For example, some people have a gender that blends elements of being a man or a woman, or a gender that is different than either male or female. Some people don't identify with any gender, or their gender changes over time.

Sustainable use assessment
gene

The basic physical and functional unit of heredity. Genes are made up of DNA, and occupy a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins.

Global assessment (1st work programme), Sustainable use assessment
gene flow

The movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.

Land degradation and restoration assessment
generalist species

A species able to thrive in a wide variety of environmental conditions and that can make use of a variety of different resources (for example, a flower-visiting insect that lives on the floral resources provided by several to many different plants).

Americas assessment, Sustainable use assessment, Europe and Central Asia assessment
genetic composition

The composition in alleles of a population.

Global assessment (1st work programme)
genetic diversity

The variation at the level of individual genes, which provides a mechanism for populations to adapt to their ever-changing environment. The more variation, the better the chance that at least some of the individuals will have an allelic variant that is suited for the new environment, and will produce offspring with the variant that will in turn reproduce and continue the population into subsequent generations.
