The research aimed to study the morphologic variation of the testis, seeking to promote the selection and genetic control of those that present appreciable spermatic production throughout the year. Testis morphology of the Rynchotus rufescens partridge was investigated, analyzing the testis weight, the seminiferous tubules diameter, the thickness of the seminiferous epithelium, the amount of me...

In avian brood parasitism, both the host and the parasite are expected to develop various conflicting adaptations; hosts develop a defense against parasitism, such as an ability to recognize and reject parasitic eggs that look unlike their own, while parasites evolve egg mimicry to counter this host defense. Hosts may further evolve to generate various egg phenotypes that are not mimicked by pa...

Assessing components of the immune system may reflect disease resistance. In some invertebrates, heat shock proteins (HSPs) are immune effectors and have been described as potent activators of the innate immune response. Several diseases have become a threat to abalone farming worldwide; therefore, increasing disease resistance is considered to be a long-term goal for breeding programs. A trait...

Quimsacocha National Recreation Area is located on the western slope of Andes in Azuay Province, southern Ecuador. All sampling locations were high paramo and Andean forests (3,572 to 3,865 m). The habitats include paramo, bogs, riparian, patches elfin forests, secondary cloud forest. We set Sherman, pitfall, camera traps (3,600 trap nights), mist nets collect 117 specimens. Eight species colle...

The mirine plant bug genus Diognetus Distant, 1904 (Hemiptera: Heteroptera: Miridae: Mirinae: Mirini) is revised. Eighteen Oriental and Eastern Palearctic species are properly assigned to the genus. Diplotrichiella Poppius, 1915, syn. nov. Yamatolygus Yasunaga, 1994, synonymized with Diognetus; accordingly following two new combinations, one substitute name synonymy proposed: flavigenis (Horvát...
