A cama is a hybrid between a male dromedary camel and a female llama, and has been produced via artificial insemination at the Camel Reproduction Centre in Dubai. [1] The first cama was born on January 14, 1998.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
Split into two volumes, these books contain all known mammal species, split into 27 orders, 167 families, 1,343 genera, 6,554 species, with 104 being extinct and 19 domesticated. They also feature more than 7,250 illustrations, including 800 new ones of primates and more than 100 of other groups. It was published in September 2020.
The most common hybrid between South American camelids, [1] huarizo tend to be much smaller than llamas, with their fibre being longer. [2] Huarizo are sterile, but recent genetic research conducted at the University of Minnesota Rochester suggests that it may be possible to preserve fertility with minimal genetic modification.
Induced ovulation occurs in various carnivoran species, [15] including most felids [16] and several species of mustelids. [17] Many bear species are able to have induced ovulation including the grizzly bear, black bear and polar bear where both the presence of a male and mating itself are requirements for induced ovulation. However, there are ...
The switch between sexuality and parthenogenesis in such species may be triggered by the season (aphid, some gall wasps), or by a lack of males or by conditions that favour rapid population growth (rotifers and cladocerans like Daphnia). In these species asexual reproduction occurs either in summer (aphids) or as long as conditions are favourable.
The discovery rate of siphonophore species was slow in the 18th century, as only four additional species were found. [11] During the 19th century, 56 new species were observed due to research voyages conducted by European powers. [11] The majority of new species found during this time period were collected in coastal, surface waters. [11]
