Saklıgöl (Denizli) Population Size of Pelophylax bedriagae (Levantine frog) Species

Prevalence and pathology of Lernaea cyprinacea (Crustacea: Lernaeidae) parasitizing tadpoles of Pelophylax bedriagae (Anura: Ranidae) in Antalya, Turkey. This is a report of the frst record of the occurrence of Lernaea cyprinacea on tadpoles of Pelophylax bedriagae, a frog species native from Karpuzçay Creek, Antalya, Turkey. A total of 20 tadpoles of P. bedriagae were examined and 14 (70%) specimens were infected. A maximum of two parasites per host was found, primarily around the cloaca. In general, slight to moderate hyperemia was noticed around the parasite. Typically, granuloma form in the tissues around the parasite. Histopathological examination revealed that hemorrhages and pathological lesions such as dermal erosions, and a chronic infammatory reaction in skin and muscle were present at the site of parasite attachment.

The Impact

The impact of fire on anurans is generally poorly understood and the response appears to vary between species, habitats and regions (Pilliod et al. 2003). Studies monitoring population size following fires have observed populations increasing (Kirkland et al. 1996; Roberts et al. 1999), remaining stable (Bamford 1992; deMaynadier and Hunter 1995; Lemckert et al. 2004) and decreasing (Bamford 1992; Driscoll and Roberts 1999; Papp and Papp 2000), with one study observing a localized extinction (Lemckert 2000). Therefore, when fire has a negative impact, it can be severe and present a serious management issue.

Metabolic Activities

Space Lab 3 (SL-3) was flown on Shuttle Challenger providing an opportunity to measure the effect of spaceflight on rat testes. Cannon developed the idea that organisms react to unfavorable conditions with highly integrated metabolic activities. Selye summarized the manifestations of physiological response to nonspecific stress and he pointed out that atrophy of the gonads always occurred. Many papers have been published showing the effects of social interaction, crowding, peck order and confinement. Flickinger showed delayed testicular development in subordinate roosters influenced by group numbers, social rank and social status. Christian reported increasing population size in mice resulted in adrenal hypertrophy, inhibition of reproductive maturation and loss of reproductive function in adults. Sex organ weights also declined. Two male dogs were flown on Cosmos 110 for 22 days. Fedorova reported an increase of 30 to 70% atypical spermatozoa consisting of tail curling and/or the absence of a tail.
