The tiger beetle fauna of the Maghreb region is one of the richest in the Palaearctic, including 22 species and 5 subspecies and 19% of all Palaearctic species of Cicindelinae. Assembled to their chorotypes, the Maghreb tiger beetles fall into eight different groups that include Maghreb endemics (26% of fauna), Mediterranean (7%), West Mediterranean (40%), North African (4%), Mediterranean-West...

The Rosário do Sul Group is one of the better-known tetrapod-bearing continental deposits of Triassic age. It crops out in central Rio Grande do Sul, south Brazil, and has yielded a fauna of more than 40 valid species, including temnospondyl, procolophonoideans, dicynodonts, cynodonts, sphenodontian, rhynchosaurs, and archosaurs. Its fossil record is herein briefly assessed, along with the stra...

Rumen methanogenesis represents an energy waste for the ruminant and an important source of greenhouse gas; thus, integrated studies are needed to fully understand this process. Eight fauna-free sheep were used to investigate the effect of successive inoculation with holotrich protozoa then with total fauna on rumen methanogenesis. Holotrichs inoculation neither altered rumen fermentation rate ...

The objective of this paper is to provide an integrative approach to species composition and distributional information on the weevil fauna of Islas Malvinas (Falkland Islands). A total of 22 species belonging to 11 Curculionidae genera are recorded for the archipelago. Four of these genera belong to Entiminae (i.e., Caneorhinus, Cylydrorhinus, Malvinius, and Morronia) and the remaining seven b...

Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution. Marine ectotherms' thermal tolerance is limited by their ability to maintain aerobic metabolism (oxygen- and capacity-limited tolerance), and is functionally associated with...

Three groups of five rumen and duodenum cannulated fauna-free sheep were used in a 28 d experiment. One group remained fauna-free, whereas the second (EN) and third (PP) groups, respectively, were inoculated intraruminally with the protozoan species Entodinium caudatum and Polyplastron multivesiculatum. Rumen fluid, duodenal digesta and faecal samples were collected during the last 12 d. The fl...

Six localities in the mid-Cretaceous (early Cenomanian) Khodzhakul Formation, western Kyzylkum Desert, Uzbekistan, produced mammalian remains of a possible zalambdalestoid (Bobolestes), a possible zalambdalestid, and two (Sheikhdzheilia rezvyii, gen. et sp. nov. and Eozhelestes mangit) or three zhelestids (‘‘Zhelestidae’’ indet., unnamed large sp. A). This is termed the Sheikhdzheili local faun...

Oxygen deficiency in the near-bottom water associated with eutrophication has been shown to have negative impacts on marine benthos in many Scandinavian waters. In the present study, the benthic fauna and the sedimentary habitat have been studied between 7 and 34 m depth; at 14 stations in three Swedish fjords in four different years, and at 12 stations along the Swedish coast in three differen...

The crayfish fauna of West Virginia consists of 23 species and several undescribed taxa. Most survey efforts documenting this fauna have been conducted in lotic waterways throughout the Appalachian plateau, Allegheny Mountains, and Ridge and Valley physiographic provinces. Bottomland forests, swamps, and marshes associated with large river floodplain such as the Ohio River floodplain historical...

Objective: In soil habitats, mesostigmatic mites (Acari: Mesostigmata) are among the most important predators of smallarthropods and nematodes. Methods: A study was carried out during 2009-2010 to identify theirfauna in Khorramabad county, Western Iran. Soil samples were taken from different regions. Mites were extracted by Berlese-Tullgren funnel and cleared in nesbit fluid. Microscopic slides...
