A Behavioral Analysis Of Achromatic Cue Perception By The Ant Cataglyphis Aenescens (Hymenoptera; Formicidae), Volkan Aksoy, Yilmaz Çamlitepe

Turkish Journal of Zoology

Behavioral responses of Cataglyphis aenescens foragers to various monochromatic light stimuli were tested. Foragers were trained to associate lights of 370 (UV), 440 (blue), 540 (green), and 640 nm (red) with a food reward on a circular orientation platform and were then tested to determine the threshold intensity values of these wavelengths they could perceive. Foragers significantly responded to all wavelengths at training intensities but their homeward orientation diminished with decreasing stimulus intensity. The results showed that UV and green lights could be perceived at lower intensities compared to blue and red lights. Foragers were further trained in a Y-maze …

Selective Predation On Common Voles By Tawny Owls And Long-Eared Owls In Winter And Spring, Linas Balciauskas, Laima Balciauskiene

Turkish Journal of Zoology

We studied size preferences of Tawny (Strix aluco) and Long-eared (Asio otus) Owls preying on common voles (Microtus arvalis) in the winter and spring seasons in Central Lithuania. Regression equations were used for body mass estimations. We found that both A. otus and S. aluco preferred larger M. arvalis than the average available in the population (the average body mass of predated individuals was 21.45 ± 0.12 g compared to 16.42 ± 0.16 g of snap-trapped individuals). Irrespective of the owl species, most of the predated Microtus voles were adults. In S. aluco prey, the winter proportion of young voles …

Local Concentration Of Foraging Noctule Bats (Nyctalus Noctula) As A Possible Tool To Assess The Density Of Bats In Large Forest Complexes, Michal Polakowski, Monika Broniszewska, Ireneusz Ruczynski

Turkish Journal of Zoology

Concentrations of at least 600 hunting noctule bats Nyctalus noctula were observed over the artificial shallow reservoir Siemianówka in eastern Poland. The observation indicates that noctule bats concentrate hunting during the presence of vast amounts of insects over the reservoir. We suggest that the high concentrations of noctule bats provide a potential tool for the estimation of local population size or density in large forest complexes.

Breeding Success Of The Stone Curlew Burhinus Oedicnemus In Nag Valley (1999-2001), Kharan, Pakistan, Muhammad Sajid Nadeem, Tariq Mahmood, Muhammad Mahmood-Ul-Hassan

Turkish Journal of Zoology

Variations in different breeding parameters in 2 adjacent populations of the Stone Curlew in Nag Valley were studied. A total of 106 active nests were spotted, with an overall mean clutch size of 1.42 eggs per nest. The nest and egg success of the Lope Valley population was 0.50 and 0.42, respectively, while the nest and egg success of the Kereichi population was 0.60 and 0.45. Poaching of eggs/chicks, habitat shrinkage, overgrazing, and fuel wood collection are thoughts to be the main factors affecting the breeding success of Stone Curlew in the area.

Phoretic Mites In Uni- And Bivoltine Populations Of Ips Typographus: A 1-Year Case Study, Martin Cejka, Jaroslav Holusa

Turkish Journal of Zoology

Members of the order Mesostigmata frequently use other animals to colonize suitable habitats, and thus their phoretic exploitation of bark beetles is not exceptional. We compared the abundance and species spectrum of phoretic mites in univoltine and bivoltine populations of the European spruce bark beetle Ips typographus. Two localities with high population densities of Ips typographus in the eastern part of the Czech Republic (400 and 1100 m a.s.l.) were studied. Beetles were sampled with pheromone traps baited with IT Ecolure (5 per locality). In total, 1268 I. typographus individuals were captured, from which 1662 mite individuals were collected and …

Recognition Of Two New Species Of Freshwater Crabs From The Seychelles Based On Molecular Evidence (Potamoidea: Potamonautidae)., Neil Cumberlidge, Savel Regan Daniels Phd

Journal Articles

The Afrotropical freshwater crab genus Seychellum is endemic to the granitic Seychelles in the Indian Ocean (Mahé, Silhouette, Praslin, La Digue and Frégate). Here we describe two new cryptic species of Seychellum that represent two evolutionarily separate lineages of a previously monotypic genus. This raises to three the number of species of freshwater crabs known from Seychelles. Each species is endemic to either one island (Silhouette) or to a pair of islands (Mahé and Frégate, or Praslin and La Digue). The three species can be clearly distinguished as separate lineages by DNA analysis, haplotyping and examination of gonopod characters. The …

Journal Articles

Aim Global-scale studies are required to identify broad-scale patterns in the distributions of species, to evaluate the processes that determine diversity and to determine how similar or different these patterns and processes are among different groups of freshwater species. Broad-scale patterns of spatial variation in species distribution are central to many fundamental questions in macroecology and conservation biology. We aimed to evaluate how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species.

Location Global.

Methods We compiled geographical range data on 7083 freshwater species of mammals, amphibians, reptiles, fishes, crabs and crayfish to …

Breeding Ecology And Behaviour Of The Great Reed Warbler, Acrocephalus Arundinaceus, In Poyrazlar Lake, Turkey, Ali̇ Uzun, Zehra Ayyildiz, Faruk Yilmaz, Belgi̇n Uzun, Mehmet Sağiroğlu

Turkish Journal of Zoology

In this study, the breeding ecology and behaviour of the Great Reed Warbler, Acrocephalus arundinaceus, was studied at Poyrazlar Lake, Turkey. The breeding period started in the first week of May. The incubation period lasted 14 days. As clutch size increased, the diameter of the nests became larger (r = 0.65). Diameters of nests containing different clutch sizes varied significantly from one another (P < 0.01). However, their height did not change (r = 0.24). There was no significant height difference between nests containing different clutch sizes (P > 0.05). As the nests became farther from the shore, the clutch size and the egg weight increased, because mature adults built their nests on the reeds in deeper areas (r = 0.59, r = 0.73). On …
