Predation by Gray Catbird on Brown Thrasher Eggs
March 2004 Notes 101 PREDATION BY GRAY CATBIRD ON BROWN THRASHER EGGS JAMES W. RIVERS* AND BRETT K. SANDERCOCK Kansas Cooperative Fish and Wildlife Research Unit, Division of Biology, Kansas State University, Manhattan, KS 66506 (JWR) Division of Biology, Kansas State University, Manhattan, KS 66506 (BKS) Present address of JWR: Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106 *Correspondent: [email protected] ABSTRACT The gray catbird (Dumetella carolinensis) has been documented visiting and breaking the eggs of arti®cial nests, but the implications of such observations are unclear because there is little cost in depredating an undefended nest. During the summer of 2001 at Konza Prairie Bio- logical Station, Kansas, we videotaped a gray catbird that broke and consumed at least 1 egg in a brown thrasher (Toxostoma rufum) nest. Our observation was consistent with egg predation because the catbird consumed the contents of the damaged egg after breaking it. The large difference in body mass suggests that a catbird (37 g) destroying eggs in a thrasher (69 g) nest might risk injury if caught in the act of predation and might explain why egg predation by catbirds has been poorly documented. Our observation indicated that the catbird should be considered as an egg predator of natural nests and that single-egg predation of songbird nests should not be attributed to egg removal by female brown-headed cowbirds (Molothrus ater) without additional evidence. RESUMEN El paÂjaro gato gris (Dumetella carolinensis) ha sido documentado visitando y rompien- do los huevos de nidos arti®ciales, pero las implicaciones de dichas observaciones no son claras porque hay poco costo por depredar un nido sin defensa. -
Mammals of the California Desert
MAMMALS OF THE CALIFORNIA DESERT William F. Laudenslayer, Jr. Karen Boyer Buckingham Theodore A. Rado INTRODUCTION I ,+! The desert lands of southern California (Figure 1) support a rich variety of wildlife, of which mammals comprise an important element. Of the 19 living orders of mammals known in the world i- *- loday, nine are represented in the California desert15. Ninety-seven mammal species are known to t ':i he in this area. The southwestern United States has a larger number of mammal subspecies than my other continental area of comparable size (Hall 1981). This high degree of subspeciation, which f I;, ; leads to the development of new species, seems to be due to the great variation in topography, , , elevation, temperature, soils, and isolation caused by natural barriers. The order Rodentia may be k., 2:' , considered the most successful of the mammalian taxa in the desert; it is represented by 48 species Lc - occupying a wide variety of habitats. Bats comprise the second largest contingent of species. Of the 97 mammal species, 48 are found throughout the desert; the remaining 49 occur peripherally, with many restricted to the bordering mountain ranges or the Colorado River Valley. Four of the 97 I ?$ are non-native, having been introduced into the California desert. These are the Virginia opossum, ' >% Rocky Mountain mule deer, horse, and burro.

Factors Affecting Feeding and Brooding of Brown Thrasher Nestlings.-The Nest- Ling Period Is a Particularly Stressful Time in the Lives of Birds
GENERAL NOTES 297 wind. An adult California Gull (Larus c&ornicus) was flying east 5 m above the water, 50 m from the shore, close to 150 Barn Swallows (Hirundo rustica) that were foraging low over the water. One swallow, heading west, passed 1 m below the gull, which dropped suddenly and caught the swallow with its bill, glided for a few meters and settled on the water. The gull proceeded to manipulate the swallow in its bill for 30 set before swallowing the still moving bird head first. The gull sat on the water for 20 min, then continued its flight to the east. Most reports of adult birds being taken by gulls have occurred while the prey were on land or water, e.g., Manx Shearwater (Puffi nus &&us) and Common Puffins (Fratercula arctica) in nesting colonies as they go to and from their burrows (Harris 1965), sick or injured birds up to the size of geese (Witherby 1948), Rock Doves (Columba &via) (Jyrkkanen 1975) and Eurasian Starlings (Sturnus vulgaris) (Drost 1958) at grain piles and ground-dwelling birds which associate with gulls (e.g., Witherby 1948). Gull predation of adult birds on water is much rarer but does occur (Hafft, Condor 73:253, 1971). Attacks and capture of avian prey on the wing has rarely been reported and generally occurs over sea on migration (Drost 1958). Bannerman (1962) reports Herring Gulls (L. argentatus) capturing and eating Redwings (Turdus musicus) and Eurasian Blackbirds (2.’ merula) as they migrate over water by knocking the weary birds into the water. -

The Naked Mole-Rat As an Animal Model in Biomedical Research: Current Perspectives
Open Access Animal Physiology Dovepress open access to scientific and medical research Open Access Full Text Article REVIEW The naked mole-rat as an animal model in biomedical research: current perspectives Laura-Nadine Schuhmacher Abstract: The naked mole-rat (NMR) is a subterranean rodent that has gained significant Zoé Husson attention from the biomedical research community in recent years as molecular mechanisms Ewan St. John Smith underlying its unusual biology start to be unraveled. With very low external mortality, NMRs have an unusually long lifespan while showing no signs of aging, such as neuro- Department of Pharmacology, University of Cambridge, Cambridge, UK degeneration or cancer. Furthermore, living underground in large colonies (100 to 300 animals), results in comparatively high carbon dioxide and low oxygen levels, from which NMRs have evolved extreme resistance to both hypoxia and hypercapnia. In this paper we have summarized the latest developments in NMR research and its impact on biomedical research, with the aim of providing a sound background that will inform and inspire further For personal use only. investigations. Keywords: naked mole-rat, longevity, cancer, hypoxia, nociception, pain Introduction The naked mole-rat (NMR) (Heterocephalus glaber) is a subterranean mammal, which has recently gained interest from scientists across a variety of research fields. Unlike the majority of mammals, NMRs are poikilothermic and eusocial, ie, are cold-blooded and have a single breeding female within a colony.1 In addition to these features, which have limited biomedical translatability, NMRs have also evolved several physiological adaptations to habituate to their extreme environmental conditions, which have led researchers to study this mammal with the hypothesis Open Access Animal Physiology downloaded from https://www.dovepress.com/ by 131.111.184.102 on 07-Sep-2017 that by understanding the extreme biology of NMRs, more will be understood about normal mammalian physiology. -

Tre matodes were recovered from ten hosts and include the following: Bra chylaima sp.
