State
Condition, at a given moment, of a biodiversity component (species or ecosystem), characterized by its structure, functioning and species community (for ecosystems), or by its abundance, distribution, traits and genetics (for species).
Condition, at a given moment, of a biodiversity component (species or ecosystem), characterized by its structure, functioning and species community (for ecosystems), or by its abundance, distribution, traits and genetics (for species).
Consequence of one or more anthropogenic pressures or responses on one of the components of biodiversity. Different pressures can have the same impact.
Beneficial flora refers to all animals that are naturally useful to crops. They regulate harmful species or the development of diseases such as powdery mildew. They also reduce the use of pesticides. Beneficial flora mainly consists of insects but certain mammals, birds and reptiles are also a part of it. There are three types of beneficial flora:
The brown marmorated stink bug (Halyomorpha halys) is a polyphagous pest native to Asia. It measures between 12 and 17 mm in length and 7 to 10 mm in width, and it is recognizable by the light-dark pattern on its antennae.
The brown marmorated stink bug is also known for occasionally invading homes in large numbers during autumn as it seeks shelter to overwinter.
The brown marmorated stink bug is a hemipteran insect from the Pentatomidae family. The flattened part (connexivum) that extends laterally from the abdomen features alternating light rectangular spots and black spots. On its underside, the abdomen lacks a ventral tip (unlike the mottled shield bug, with which it is often confused).
In France, the brown marmorated stink bug reproduces once a year, with reproduction occurring in summer. The female lays 27–28 eggs, which hatch 3 to 6 days after oviposition (egg deposition on a surface). There are five larval stages before reaching adulthood. The brown marmorated stink bug is a polyphagous piercing insect that feeds on fruits (apples, cherries, peaches, raspberries), vegetables (tomatoes, eggplants, peppers), and ornamental plants (butterfly bush, hibiscus).
The African Clawed Frog (Xenopus laevis) is an amphibian from the Pipidae family. Its body is flattened and smooth, gray-brown marbled with black spots, with lateral seams on its sides, throat, and belly. Its eyes are positioned on top of its head, and it lacks a tympanum. Highly aquatic, this species can also move on land for several hundred meters.
Adults hibernate in the mud at the bottom of the water.
Insects with incomplete metamorphoses, with aquatic larvae, such as dragonflies and damselflies.
Order of hemimetabolic insects, terrestrial in the adult state, aquatic in the larval state, known under the name of Dragonflies or Damselflies, and whose adults are characterised by a large and mobile head, bearing very developed compound eyes, very short and filiform antennae, a crushing type mouth apparatus, by small and weak legs used mainly for gripping prey, by very large, membranous, hyaline or coloured wings, with a tight network of small veins which, at rest, are held vertical or oblique behind (Zygoptera) or arranged more or less horizontally (Anisoptera)
Environmental DNA (eDNA) is defined as DNA that can be extracted from environmental samples, such as water, soil or feces, without the need to first isolate target organisms.
Inventaire des milieux et espèces présents sur un territoire donné. Il implique l'ensemble des acteurs d'une commune (élus, citoyens, associations, entreprises, ...) en faveur de la préservation du patrimoine naturel. La réalisation de cet inventaire permet de cartographier les enjeux de biodiversité à l'échelle de ce territoire.
Elle vise à la conservation de tous les oiseaux sauvages dans l’Union européenne (UE) en fixant des règles pour leur protection, leur conservation, leur gestion et leur régulation. Elle s’applique aux oiseaux ainsi qu’à leurs œufs, à leurs nids et à leurs habitats. Les pays de l’UE classent en zones de protection spéciale (ZPS) les territoires les plus appropriés en nombre et en superficie à la conservation de ces espèces dans les zones maritimes et terrestres d’application de la présente directive. Une attention particulière doit être portée aux zones humides. Les ZPS font partie du réseau de sites protégés Natura 2000, au même titre que les…
Espaces délimités en mer qui répondent à des objectifs de protection de la nature à long terme. Le code de l’environnement reconnaît différentes catégories d’aires marines protégées. La plupart des aires marines protégées permettent de concilier les enjeux de protection et le développement durable d’activités.
Le code de l'environnement (article L334-1 modifié le 24/07/2019), reconnaît différentes catégories d'aires marines protégées qui répondent chacune à des objectifs propres tout en étant complémentaires.
Espaces délimités en mer au sein duquel un objectif de protection de la nature à long terme a été défini, objectif pour lequel un certain nombre de mesures de gestion sont mises en œuvre : suivi scientifique, programme d’actions, chartes de bonne conduite, protection du domaine public maritime, réglementations, surveillance, information du public, etc. Sur la base de cette définition, l’objectif de protection n’est pas exclusif d’autres objectifs, notamment de développement économique maîtrisé (utilisation et exploitation durables des ressources marines).
