Despite a significant number of studies on the reproductive characteristics of small mammals, very little of this work has been conducted on species in Egpyt. Here, the Egyptian greater gerbil (Gerbillus pyramidum Saint-Hilaire, 1825) and Anderson's lesser Egyptian gerbil (Gerbillus andersoni De Winton, 1902) in northeastern Egypt were surveyed. Breeding behavior in these species was synchronized with rainfall in the winter and spring months. Surprisingly however, the removal of individual gerbils throughout the course of study resulted in an extension of reproductive activity into the dry summer and autumn months in the latter part of the sampling. These results are discussed in the context of density-dependent reproductive behavior in small mammals.

Genomic resources are important and attainable for examining evolutionary change in divergent natural populations of non-model species. We utilized two Next Generation Sequencing (NGS) platforms, 454 and SOLiD 5500XL, to assemble low coverage transcriptomes of the white-footed mouse (Peromyscus leucopus), a widespread and abundant native rodent in eastern North America. We sequenced liver mRNA transcripts from multiple individuals collected from urban populations in New York City and rural populations in undisturbed protected areas nearby, and assembled a reference transcriptome using 1,080,065,954 SOLiD 5500XL (75 bp) reads and 3,052,640 454 GS FLX + reads. The reference contained 40,908 contigs with a N50 = 1,044 bp and a total content of 30.06 Megabases (Mb). Contigs were annotated from comparisons to Mus musculus (39.96% annotated) Uniprot databases. We identified 104,655 high quality single nucleotide polymorphisms (SNPs) and 65 single sequence repeats (SSRs) with flanking primers. We also used normalized read counts to identify putative gene expression differences in 10 genes between populations. There were 19 contigs significantly differentially expressed in urban populations compared to rural populations, with gene function annotations generally related to the translation and modification of proteins and those involved in immune responses. The individual transcriptomes generated in this study will be used to investigate evolutionary responses to urbanization. The reference transcriptome provides a valuable resource for the scientific community using North American Peromyscus species as emerging model systems for ecological genetics and adaptation.

What's stopping you? Variability of interstate highways as barriers for four species of terrestrial rodents

et al. 2018

Landscape features that form a barrier for one species may not be a barrier for others, depending on how each species perceives the feature. Barriers may not be equivalent, due to unique characteristics at different locations, which may ameliorate barrier effects. In this study, we employed population genetics techniques to investigate how four Rodentia species with differing life history characteristics (fox squirrels [Sciurus niger], eastern gray squirrels [Sciurus carolinensis], eastern chipmunks [Tamias striatus], and white‐footed mice [Peromyscus leucopus]) responded to interstate highways as barriers to movement at seven locations with differing site‐specific landscape features. For comparative purposes, we included control sites that lacked heavily trafficked roads. We detected genetic differentiation relative to interstate highways among the gray squirrels, chipmunks, and white‐footed mice, but signals for differentiation among those three species varied by site, suggesting that site‐specific features are important considerations for species responses to high‐traffic roads. Chipmunk and gray squirrel populations, two forest specialist species that avoid open areas, exhibited more genetic structure corresponding with highways than either white‐footed mice (a nocturnal generalist) or fox squirrels (a larger‐bodied specialist that traverses open areas more readily than the other species in this study). Fox squirrels did not exhibit genetic differentiation at any site, whereas gray squirrel study populations evinced no population differentiation at sites with bridges spanning the interstate highway. Chipmunks also exhibited population differentiation at two of the control sites, indicating that less obvious barriers in the landscape may be as important as roads for sensitive species. We interpreted variation in genetic differentiation of species across sites in the context of how interstate highway features (i.e., the presence and condition of drainage culverts and bridges near study sites), combined with species‐specific life history characteristics, influence the barrier potential of highways. Culvert presence generally corresponded with a low or nonexistent barrier effect; however, an open, large culvert (>8 m in height) may create a semi‐permeable barrier for species that avoid open areas. Bridge presence appeared to facilitate gray squirrel and chipmunk dispersal across highways.
