Human–Wildlife Interactions
Before immunocontraceptives can be considered safe to use on wildlife species, potential health risks should be assessed. Gonadotropin-releasing hormone (GnRH) immunocontraceptive has successfully reduced fertility of white-tailed deer (Odocoileus virginianus); however, associated deer physiology has rarely been examined. We conducted gross necropsy examinations, histology, and blood chemistry comparisons on euthanized deer previously vaccinated with immunogenic GnRH (n = 18 females and n = 4 males), or left as untreated controls (n = 7 females and n = 6 males). Granulomas were found at injection sites of most deer, even 3 years post-treatment. There were no significant …

Growth, Mortality, And Reproduction Of Poor Cod (Trisopterus Minutus Linn., 1758) In The Central Aegean Sea, Gülnur Meti̇n, Akin Türker İlkyaz, Hasan Tuncay Kinacigi̇l
Turkish Journal of Zoology
A total of 1527 of poor cod (Trisopterus minutus Linn., 1758) were collected by trawl hauls between April 2001 and March 2002 from İzmir Bay (central Aegean Sea). The size of the fish (total length) ranged from 10.6 cm (minimum, September) and 24.8 cm (April). The population was composed of 53% males, 41% females, and 6% immature individuals, with a female to male ratio of 1:1.3. The age composition of the samples was from I to V. The von Bertalanffy growth parameters were L_{\infinity} = 28.1 cm, W_{\infinity} = 254.0 g, K = 0.26 y^{-1}, and t_{o} = -1.52 y. …

Alleles of physiological candidate genes for reproductive traits, insulin-like growth factor-1 (IGF-1), and growth hormone receptor (GHR) were assessed to determine their associations with total egg production (NE), average days of continual egg-laying (ADCE), and number of double yolk eggs (DYE) in Wenchang chickens (Chinese indigenous breed). PCR-RFLP was used for genotype identification. The frequency of restriction enzyme C1/C2 alleles in the population was 0.53 (C1) and 0.47 (C2) for IGF-1. For GHR-intron 2 it was 0.06 and 0.94 for (A1) and (A2), respectively, while for GHR-intron 5 it was 0.20 (B1) and 0.80 (B2). Four significant associations were found …
