The salamander family Hynobiidae contains over 50 species and has been the subject of a number of molecular phylogenetic investigations aimed at reconstructing branches across the entire family. In general, studies using the greatest amount of sequence data have used reduced taxon sampling, while the study with the greatest taxon sampling has used a limited sequence data set. Here, we provide i...

У роботі представлені результати досліджень фауни донних ракоподібних (Copepoda, Harpacticoida) у джерелах, які знаходяться на територіях басейнів річок Тиса (басейн Дунаю) та Дністер в межах України. 46-и пробах мікрозообентосу з джерел знайдено гарпактицид. В цілому, було виявлено 18 видів гарпактицид: 14 водоймах басейну Тиси і 17 Дністра. Найчастіше, зообентосу зустрічалися Attheyella (Atth...

Although contemporary trends indicative of evolutionary change have been detected in the life-history traits of exploited populations, it is not known to what extent fishing influences the evolution of alternative life-history tactics in migratory species such as salmonids. Here, we build a model to predict the evolution of anadromy and residency in an exploited population of brook charr, Salve...

A short diagnosis and a more detailed diagnosis of the genus Laelaspis are presented. Until now, a total of 40 described species belong to the genus, including a new species described here, and excluding the four following species previously described as Laelaspis or Hypoaspis (Laelaspis): L. badrii Nasr & Nawar [considered as Cosmolaelaps badrii comb. nov.], L. zuluensis Trägårdh, Hypoaspis (L...

In this study, there is a description of a new species, Protzia longiacetabulata n.sp., and P. squamosa Walter, 1908 representing a new Protzia record for the fauna of Turkey. Protzia longiacetabulata n.sp. is closest to the P. halberti from the P. rotunda species group and identified from these species by the number of the leg claws and acetabuli. Furthermore, there is the first description of...

A common dimorphism in life-history tactic in salmonids is the presence of an anadromous pathway involving a migration to sea followed by a freshwater reproduction, along with an entirely freshwater resident tactic. Although common, the genetic and environmental influence on the adoption of a particular life-history tactic has rarely been studied under natural conditions. Here, we used sibship-...
