Use of frozen-thawed semen in equine artificial insemination programmes [PDF]
SPERMOVA, 2016 The use of equine frozen semen has variable results. Pregnancy rates per cycle may be between 10 to 70%. Although an inseminating dose of 280 a 320 millones progressive motile sperm (PMS) has been recommended, under experimental conditions it is posible ...

Insect Science, EarlyView.Abstract The Sterile Insect Technique (SIT) is an effective strategy for controlling insect pests, such as the Mediterranean fruit fly (Ceratitis capitata, Wiedemann). The effectiveness of the SIT depends on the ability of the sterile males to mate and their capacity to induce sterility in wild females.

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

One number to rule them all: The Wildlife Sperm Index for standardized gamete assessment
Methods in Ecology and Evolution, EarlyView.Abstract In wildlife conservation, breeding programmes focused on reintroduction are critical to recovering endangered species. Assisted reproductive technologies (ARTs) and biobanking play pivotal roles in these efforts but depend on high‐quality gametes.

Pre- and post-parturial aspects of scorpion reproduction: a review
European Journal of Entomology, 2012 Although scorpions are an ancient group their method of reproduction is rather complex and poorly studied. This review aims at clarifying some of the aspects of their reproduction that are important for understanding the reproductive ecology of other ...
