Pollination assessment
flower-visitor

An animal that visits flowers (a.k.a. anthophile) but is not necessarily a pollinator.

Sustainable use assessment, Global assessment (1st work programme)
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.

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

Pollination assessment
observing

Observing is defined as a non-extractive practice that is based on the observation of wild species. The observation can imply some interaction with the wild species, such as the activities of wildlife tourism and whale watching or no interaction with the wild species, such as photography.

oil spill

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.

Asia-Pacific assessment
old-growth forest

From an ecological point of view, old-growth forests are a stage of forest development characterized by large/old trees and structural complexity including live and dead trees, and vertical and horizontal heterogeneity (including a multi-layered canopy). The structural diversity of old growth forests often supports distinctive/specialist biodiversity; large/old trees are keystone components of the ecosystem (Lindenmayer et al., 2012). In addition, the long-period of forest development without stand replacement disturbance allows many poor-dispersing species to accumulate (IUFRO, 2018). Other definitions can be found based on economic and social perspectives (Hilbert & Wienscczyk, 2007).

Global assessment (1st work programme)

Sustainable use assessment
one biosecurity

interdisciplinary approach to biosecurity policy and research that builds on the interconnections between human, animal, plant, and environmental health to effectively prevent and mitigate the impacts of invasive alien species. It provides an integrated perspective to address the many biosecurity risks that transcend the traditional boundaries of health, agriculture, and the environment. Individual invasive alien plant and animal species often have multiple impacts across sectors: as hosts of zoonotic parasites, vectors of pathogens, pests of agriculture or forestry, as well as threats to biodiversity and ecosystem function

Invasive alien species assessment

It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and interdependent (One Health High-Level Expert Panel

Invasive alien species assessment
ontology
