Дефиниција: overall repetitive or reflective pattern in the body of one individual of this taxon. eg: bilateral symmetry, rotational symmetry, radial symmetry
Дефиниција: Living in the fluid medium (water or air) but unable to maintain their position or distribution independently of the movement of the water/air mass (adapted from Lincoln et al., 1998).
Дефиниција: Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke. When they push water directly backwards, this moves their body forward, but as they return their limbs to the starting position, they push water forward, which will thus pull them back to some degree, and so opposes the direction that the body is heading. This opposing force is called drag. The return-stroke drag causes drag swimmers to employ different strategies than lift swimmers. Reducing drag on the return stroke is essential for optimizing efficiency.
Дефиниција: Height (dorso-ventral distance) of the prosome of an arthropod. Prosome: anterior region of body, commonly limited behind by major articulation. Collective term for the combined cephalasome and metasome in copepods
Дефиниција: Length of the prosome of an arthropod. Prosome: anterior region of body, commonly limited behind by major articulation. Collective term for the combined cephalasome and metasome in copepods
Дефиниција: Width of the prosome of an arthropod. Prosome: anterior region of body, commonly limited behind by major articulation. Collective term for the combined cephalasome and metasome in copepods
Дефиниција: A group of species that exploit the same food resources, and/or use the same feeding or foraging methods. http://en.wikipedia.org/wiki/Guild_(ecology)
