The ant community living in leaf litter was assessed in 65 forest sites in the Brazilian Atlantic rainforest in the southern region of the state of Bahia, Brazil. In addition, we aimed to understand the patterns between taxonomic and functional diversities using two different resolutions of classification of ants into functional groups. We identified 364 ant species belonging to 68 genera in 10 subfamilies in 65 regions. Considering a more general functional classification, we identified a total of 13 functional ant groups, and 26 functional ant groups considering a more specific functional classification. The Atlantic Forest environments studied presented great …

Spatiotemporal Distribution And Population Structure Of Clibanarius Symmetricus (Randall, 1840) (Crustacea, Diogenidae) In An Amazon Estuary, Ana Carolina Melo Rodrigues, Jussara Moretto Martinelli-Lemos
Turkish Journal of Zoology
Rocky outcrops in the intertidal zones of estuaries often contain a highly diverse microbenthic community which includes the hermit crab, Clibanarius symmetricus, an abundant species on the equatorial Amazon coast. However, the ecology of this anomuran is poorly understood. Given this, the present study investigated the spatiotemporal distribution and structure of the C. symmetricus populations that inhabit the rocky outcrops of the Marapanim estuary in northern Brazil. Samples were collected monthly over a yearly cycle covering both the dry and rainy seasons in the upper and lower midlittoral zones during low tide. The distribution and abundance of C. symmetricus were …

Application Of Multifactorial Discriminant Analysis In The Morphostructural Differentiation Of Wild And Cultured Populations Of Vieja Azul (Andinoacara Rivulatus), Johanna Caez, Ana Gonzalez, Martin A. Gonzalez, Elena Angon, Jorge M. Rodriguez, Francisco Peña, Cecilio Barba, Antón García
Turkish Journal of Zoology
To better determine the ecological variation (body shape and structure) of the Vieja Azul (Andinoacara rivulatus; syn.: Aequidens rivulatus) in northwest Ecuador (Los Ríos Province), 300 specimens of both sexes (150 male and 150 female) were collected from 3 different locations, one from a wild production system and two from fish farm populations in the Quevedo River. Twelve meristic, 26 traditional morphometric, and 32 truss measurements, among 25 anatomical landmarks, were determined. The body weight (BW), total length (TL), eye diameter (ED), dorsal fin ray length (DFRL), and body perimeter 3 (P3) showed significant differences (P < 0.05) between production systems, and sex had significant influence on preanal length (Pre-AL), P3, and body width 2 (LC2). Females showed higher mean values than males in all measurements, except for BW. The Fulton factor differed for both factors considered. The canonical discriminant analysis revealed a percentage of correct assignment of 64.42% for the dataset, 85% and 60.9% for cultured and wild females, and 62.1% and 56.3% for wild and cultured males, respectively, as well as morphometric variation between groups. Results could be attributed to environmental conditions (habitat, temperature, and food). The Mahalanobis test showed greater distances among females than among males. In conclusion, this study provides valuable morphological information on the shape and structure of Andinoacara rivulatus that can be used to characterize and quantify the changes that occur as a consequence of adaptation to a different habitat. The authors hope that the information obtained from the present study will be helpful for fisheries, biologists, and taxonomists.

Turkish Journal of Zoology
In the Lower Triassic, at the time that segminate gondolellid conodonts defined the Tethyan regions, endemic segminiplanate gondolellid conodonts resembling the genus ?Neogondolella? dwelled in the northern latitudes. Without the multielement apparatus characteristic of the subfamily Neogondolellinae, these forms are phylogenetically incertae sedis and one lineage was attributed to the genus Siberigondolella gen. nov.
Validation Of Reference Genes For Quantitative Expression Analysis By Qpcr In Various Tissues Of Date Mussel (Lithophaga Lithophaga), Urska Sivka
Turkish Journal of Zoology
qPCR is a very popular method for identifying nucleotide sequences as a result of its sensitivity and relatively low cost and technical simplicity. Normalization is one of the most important steps in analyzing qPCR data and the use of reference genes is the most common normalization strategy. In the present study five commonly used reference genes (18S, 28S, ef1a, ß-act, and ?-tub) were evaluated for their stability in the mantle, gill, foot, and pallial gland of date mussel (L. lithophaga) in different seasons. Four different software packages were used for evaluation: geNorm, NormFinder, BestKeeper, and RefFinder. Although these programs contain …

On Tooth Anomalies And The Loss Of Canis Lupus (Mammalia: Carnivora) In Turkey, Eli̇f Yildiz Ay, İrfan Albayrak
Turkish Journal of Zoology
Because of their feeding habits, which are affected by their ranking in the last steps of the food chain, the teeth of carnivores are subjected to great forces during the breaking up and chewing of food when they are hunting. In this sense, missing teeth and tooth anomalies are common in carnivores. This research was based on an examination of the properties of the tooth structures of 25 wolf specimens collected in Turkey between 2014 and 2018. In this study, the excess and missing teeth, tooth fracture, and root anomalies in the lower and upper jaw of the head skeletons …

The violet carpenter bee is a species which can chiefly be found around the Mediterranean Sea and the Black Sea. This bee species has rarely been found in Poland, which is the northernmost area of its occurrence. Between 1868 and 1935, the Xylocopa violacea (Linnaeus, 1758) was observed at only 8 locations in Poland. There were then no reports of the occurrence of this bee species in Poland for 70 years. The species was noted again in 2005; between 2005 and 2017, it was noted at 20 locations. This study provides detailed data on the history of the distribution of …
