The green tides caused by the overgrowth of Ulva prolifera in the Yellow Sea of China have been occurring every summer since 2007. The green tide is a major environmental concern that involves the impacts from natural, anthropogenic, physicochemical and algae factors along with the warming of local water.
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).
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".
Other animals reproduce sexually with external fertilization, including many basal vertebrates. Vertebrates reproduce with internal fertilization through cloacal copulation (in reptiles, some fish, and most birds) [ 3 ] or ejaculation of semen through the penis into the female's vagina (in mammals ).

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.
Dog breeding is the practice of mating selected dogs with the intention of maintaining or producing specific qualities and characteristics. When dogs reproduce without such human intervention, their offspring's characteristics are determined by natural selection , while "dog breeding" refers specifically to the artificial selection of dogs, in ...
