One example of functional equivalence is demonstrated in plant-pollinator relationships, whereby a certain plant species may evolve flower morphology that selects for pollination by a host of taxonomically-unrelated species to provide the same function (fruit production following pollination). [3]
Saltwater aquaponics. Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
Sequential hermaphroditism occurs in many fish, gastropods, and plants. Species that can undergo these changes do so as a normal event within their reproductive cycle, usually cued by either social structure or the achievement of a certain age or size. [3]
Posidonia oceanica is a flowering plant which grows in dense meadows or along sandy channels in the waters of the Mediterranean. It is found at depths of 1–35 metres (3.3–114.8 ft), [8] depending on water clarity. Subsurface rhizomes and roots stabilize the plant, while erect rhizomes and leaves reduce silt accumulation.
A species is considered semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles over the course of its lifetime. Iteroparity can be further divided into continuous iteroparity (primates, including humans and chimpanzees) and seasonal iteroparity ...
Electroreception and electrogenesis are the closely related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups of fishes (most famously the electric eel, which is not actually an eel but a knifefish) to stun prey.
The Los Angeles Times recently requested a tour of the pumping plant and its nearby fish-collecting facility to gain insights into California's struggle to uphold environmental protections while ...
Hypostomus plecostomus, also known as the suckermouth catfish or common pleco, is a tropical freshwater fish belonging to the armored catfish family ( Loricariidae ), named for the longitudinal rows of armor -like scutes that cover the upper parts of the head and body (the lower surface of head and abdomen is naked soft skin).
Prism correction is measured in prism dioptres. A prescription that specifies prism correction will also specify the "base". The base is the thickest part of the lens and is opposite from the apex. Light will be bent towards the base and the image will be shifted towards the apex.
Polyandry in fishes is a mating system where females mate with multiple males within one mating season. [1] This type of mating exists in a variety of animal species. [1] Polyandry has been found in both oviparous and viviparous bony fishes and sharks. [2] General examples of polyandry occur in fish species, such as green swordtails [1] and ...
