Ulva prolifera (previously Enteromorpha prolifera), also known as the branched string lettuce, is a species of seaweed algae in the family Ulvaceae that can be found worldwide. [ 1 ] Description
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca , lactuca being Latin for "lettuce".
Raw parae (green laver). Green laver (/ ˈ l eɪ v ər, ˈ l ɑː v ər /), known as aonori (アオノリ; 青海苔) in Japan, sea cabbage (海白菜) or hutai (滸苔) in China, and parae (파래) and kim (김) in Korean, is a type of edible green seaweed, including species from the genera Monostroma and Ulva (Ulva prolifera, Ulva pertusa, Ulva intestinalis).
The thallus length ranges from 1.9 –36 cm with a mean length of 18.6 cm. The thallus width ranges from 0.2 to 4.8 cm with a mean width of 1.4 cm. [5] Ulva linza can be distinguished by its smooth thallus, most with a ruffled margin. [5] Ulva linza can tolerate a wide range of salinities and water qualities. [6]
A dog's glans consists of two sections: Behind the lower, long part (pars longa glandis) lies the "knot" (Bulbus glandis) [1] which expands only after penetrating the vagina and causes the male dog to remain inside the bitch ("Tie") for some time after ejaculation (typically between 15 and 30 min).
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. [39] Many species have transitioned to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.
The genus Umbraulva was first described by Bae and Lee in 2011. [1] After studying the morphology of Ulva japonica (Holmes), Ulva amamiensis, and Ulva olivascens, and analyzing their DNA sequences, Bae and Lee proposed the new genus Umbraulva, and placed the three species they initially studied into that genus as Umbraulva japonica (Holmes), Umbraulva amamiensis (Tanaka), and Umbraulva ...
Polycyclic animals reproduce intermittently throughout their lives. Semelparous organisms reproduce only once in their lifetime, [27] such as annual plants (including all grain crops), and certain species of salmon, spider, bamboo and century plant. [28] Often, they die shortly after reproduction. This is often associated with r-strategists.
