The Neotropical genus Neodischistus Painter has a distribution restricted to South (Brazil and Argentina) and Central America (Panama). The genus is composed of two previously described species that are herein revised: N. currani Painter and N. collaris Painter. One new Brazilian species is described: N. marstoni sp. nov. Illustrations of the external morphology of adults and male and female te...

Physocephala wulpi Camras was reared from Xylocopa artifex Smith, Xylocopa augusti Lepeletier, and Xylocapa splendidula Lepeletier. The puparium is described. An overview of conopid host records from the Neotropic Region, and records from Conopidae that develop in Xylocopa, is provided.

a total of 8 species of wild ducks were collected from mazandaran and guilan provinces in the north part of iran. after autopsy, a total of 30 species of different helminths, 11 sp. from anas platyrhynchos, 6 sp. from anas crecca, 3 aythya fuligula, 3 sp . from aythya ferina, 4 sp. from aythya fuligula, 3 sp. from anas strepera, 2 sp. from anser anser and 7 sp. form cygnus cygnus, were recovere...

Due to the difficulty in accurately identifying cymothoids, these parasitic isopods are often incorrectly named or confused with other species. Within the genus Ceratothoa, a number of recent studies have aimed at clarifying some of the problematic species; however, several of the less studied species still require revision. This paper redescribes, from type material, several poorly known Cerat...

Eastern collared lizards (Crotaphytus collaris collaris) on the Ozark Plateau of southern Missouri are restricted to islands of rocky glade habitat located throughout the oak–hickory forests of the region. Human mediated suppression of fire negatively impacts collared lizard populations by permitting the overgrowth and consequent disappearance of this glade habitat and also leads to a dense for...

Species identification by means of morphology is often problematic in protists. Nebela tincta-collaris-bohemica (Arcellinida) is a species complex of small to medium-sized (ca.100 μm) testate amoebae common in peat bogs and forest soils. The taxonomic validity of characters used to define species within this group is debated and causes confusion in studies of biogeography, and applications in p...

Some thrips (Thysanoptera) species are seriously harmful in vineyard production areas. Tarsus and Mut locations of Mersin Province located at the southeastern Mediterranean region Türkiye has an important place grape Türkiye. It is not known whether there vineyards these locations. For this aim, were collected 2019 by tapping different plant parts vines. A total 14 identified. Harmful such as D...

The length of the snow-free season has a significant influence on reproduction and growth in northern alpine environments, and these life history traits may provide sensitive indicators of the responses of organisms to climate change. We examined growth rates and timing of parturition of collared pikas (Ochotona collaris) from 1995-2002 in the Ruby Range, Yukon Territory, Canada. Growth rates w...
