Rose1 and Erin A. Dreelin2, Department of Biological Sciences, Old Dominion University, Norfolk, Virginia 23529-0266 ABSTRACT The objectives of our study were to determine the age of maturity, litter size, and the timing of the breeding season of marsh rice rats (Oryzomys palustris) of coastal Virginia. From May 1995 to May 1996, monthly samples of rice rats were live-trapped in two coastal tidal marshes of eastern Virginia, and then necropsied. Sexual maturity was attained at 30-40 g for both sexes. Mean litter size of 4.63 (n = 16) did not differ among months or in mass or parity classes. Data from two other studies conducted in the same county, one of them contemporaneous, also were examined. Based on necropsy, rice rats bred from March to October; breeding did not occur in December-February. By contrast, rice rats observed during monthly trapping on nearby live-trap grids were judged, using external indicators, to be breeding year-round except January. Compared to internal examinations, external indicators of reproductive condition were not reliable for either sex in predicting breeding status in the marsh rice rat.

All rights Reserved. Cite as: Bodmin KA, Champion PD, James T & Burton T (2015) New Zealand Rushes: Juncus factsheets. NIWA, Hamilton. Introduction Rushes (family Juncaceae) are a common component of New Zealand wetland vegetation and species within this family appear very similar. With over 50 species, Juncus are the largest component of the New Zealand rushes and are notoriously difficult for amateurs and professionals alike to identify to species level. This key and accompanying factsheets have been developed to enable users with a diverse range of botanical expertise to identify Juncus to species level. The best time for collection, survey or identification is usually from December to April as mature fruiting material is required to distinguish between species.

  • Cyperaceae of Alberta
    AN ILLUSTRATED KEY TO THE CYPERACEAE OF ALBERTA Compiled and writen by Linda Kershaw and Lorna Allen April 2019 © Linda J. Kershaw & Lorna Allen This key was compiled using information primarily from and the Flora North America Association (2008), Douglas et al. (1998), and Packer and Gould (2017). Taxonomy follows VASCAN (Brouillet, 2015). The main references are listed at the end of the key. Please try the key this summer and let us know if there are ways in which it can be improved. Over the winter, we hope to add illustrations for most of the entries. The 2015 S-ranks of rare species (S1; S1S2; S2; S2S3; SU, according to ACIMS, 2015) are noted in superscript ( S1; S2;SU) after the species names. For more details go to the ACIMS web site. Similarly, exotic species are followed by a superscript X, XX if noxious and XXX if prohibited noxious (X; XX; XXX) according to the Alberta Weed Control Act (2016).
