The composition of seed banks on kangaroo rat (Dipodomys spectabilis) mounds in a Chihuahuan Desert grassland

Disturbance is a major factor determining the plant community structure of ecological systems. In particular, small-scale disturbances from animals can increase heterogeneity and species diversity in plant communities. Kangaroo rat (Dipodomys spectabilis) mounds are small-scale disturbances that support unique plant communities compared to surrounding habitats. The seed bank, which is usually a...

Ultraviolet Communication in the Kangaroo Rat (Dipodomys ordii)

Recent demographic bottlenecks are not accompanied by a genetic signature in banner-tailed kangaroo rats (Dipodomys spectabilis).

Single-sample methods of bottleneck detection are now routine analyses in studies of wild populations and conservation genetics. Three common approaches to bottleneck detection are the heterozygosity excess, mode-shift, and M-ratio tests. Empirical groundtruthing of these methods is difficult, but their performances are critical for the accurate reconstruction of population demography. We use t...

Sexually differentiated effects of radio transmitters on predation risk and behaviour in kangaroo rats Dipodomys merriami

analysis without significantly affecting intestine weight o r length. If the source of carcasses is unknown, then an analysis of small intestine weight, either as a measure of intestine size o r to examine the effects of dietary, seasonal, sex, o r age differences, should be treated with caution. If the same information can be gained by examining intestine length, this is preferred. Nevertheles...

examining the relationship between fear of negative evaluation and communication strategies by iranian efl learners

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
