Three New Species and One New Record of Genus Chimarra Stephens (Trichoptera: Philopotamoidea: Philopotamidae) from Indian Himalaya Mon, 21 Jul 2014 07:24:53 +0000 Three new species and one new record are added to the philopotamid fauna of India from the Indian Himalaya. The newly described species under the genus Chimarra Stephens include Chimarra butticulata sp.n. and C. gangotriensis sp.n. both from Uttarakhand and C. sangtami sp.n. from Nagaland. The record of C. nigra Kimmins (from Sikkim) constitutes the first record of that species from India, although it was previously known from Nepal. It is redescribed here from India as there are minor differences in the male genitalia from previously described species (in original paper of Kimmins only lateral view of the phallus was illustrated and in the redescribed species the ventral view of phallus is illustrated along with the lateral view). The four species belong to two different species groups and one species is unplaced in the species group. These species are distinguishable from each other as well as from the previously known allied species by consistent taxonomic features of the inferior appendages, tergite X, and the phallic apparatus of males.

Osteometric Effects of Surgical Caponisation on Some Long Bones in Cockerel Chickens Mon, 07 Jul 2014 07:12:16 +0000 The study was conducted to assess the osteometric effects of surgical caponisation on long bones of cockerel chickens. Sixty- (60-) day-old chicks were distributed into two experimental groups with thirty (30) cockerels per group. The birds were caponised at eight (8) weeks of age. The mean of final body weights of caponized groups was significantly higher () than the uncaponised group. The weights of all long bones measured as well as lengths between the two groups were not statistically different () from one another except the weight of femur of the caponized group and the lengths of tibia and tarsometatarsus () that differed significantly from one another (). All the proximal, midshaft, and distal diameters of all the long bones measured between the two groups were not statistically different () from one another except the midshaft diameter of ulna that was significantly higher () in caponized group. It was concluded that caponisation of cockerel chickens at eight (8) weeks of age has no significant osteometric effects () on almost all the long bones studied when they were normalised to the final body weights.

Mates of Competitive Females: The Relationships between Female Aggression, Mate Quality, and Parental Care Mon, 30 Jun 2014 00:00:00 +0000 Though rarely mate-limited, females in a wide variety of species express traits commonly associated with mate competition in males. Recent research has shown that these competitive traits (ornaments, armaments, and intense aggression) often function in the context of female-female competition for nonsexual reproductive resources and are often positively related to reproductive success. Increased success could occur because competitive females acquire limited ecological resources (nest sites, territories, etc.) or because they pair with high quality males, that is, older, more ornamented, or more parental males. Further, males paired with aggressive/low care females may compensate by increasing their paternal efforts. Here, I examined patterns of social pairing and parental care in free-living dark-eyed juncos (Junco hyemalis), a biparental songbird. I found no detectable relationship between female competitive behavior (aggression) and male quality (age, size, or ornamentation) or male provisioning. Thus, neither of the mate choice hypotheses (females compete for males or males prefer aggressive females) was supported. Instead, these results suggest that females compete for nonsexual resources and mate quality is a secondary consideration. I also found a negative relationship between male and female provisioning rates, suggesting that partners adjust their level of parental effort in response to their partner’s efforts. Kristal E.
