Density, Distribution and Habitat Requirements for the Ozark Pocket Gopher (Geomys Bursarius Ozarkensis)
DENSITY, DISTRIBUTION AND HABITAT REQUIREMENTS FOR THE OZARK POCKET GOPHER (Geomys bursarius ozarkensis) Audrey Allbach Kershen, B. S. Thesis Prepared for the Degree of MASTER OF SCIENCE UNIVERSITY OF NORTH TEXAS May 2004 APPROVED: Kenneth L. Dickson, Co-Major Professor Douglas A. Elrod, Co-Major Professor Thomas L. Beitinger, Committee Member Sandra L. Terrell, Interim Dean of the Robert B. Toulouse School of Graduate Studies Kershen, Audrey Allbach, Density, distribution and habitat requirements for the Ozark pocket gopher (Geomys bursarius ozarkensis). Master of Science (Environmental Science), May 2004, 67 pp., 6 tables, 6 figures, 69 references. A new subspecies of the plains pocket gopher (Geomys bursarius ozarkensis), located in the Ozark Mountains of north central Arkansas, was recently described by Elrod et al. (2000). Current range for G. b. ozarkensis was established, habitat preference was assessed by analyzing soil samples, vegetation and distance to stream and potential pocket gopher habitat within the current range was identified. A census technique was used to estimate a total density of 3, 564 pocket gophers. Through automobile and aerial survey 51 known fields of inhabitance were located extending the range slightly. Soil analyses indicated loamy sand as the most common texture with a slightly acidic pH and a broad range of values for other measured soil parameters and 21 families of vegetation were identified. All inhabited fields were located within an average of 107.2m from waterways and over 1,600 hectares of possible suitable habitat was identified.

ORIGINAL RESEARCH published: 22 April 2021 doi: 10.3389/fsufs.2021.632624 Assessment of Livestock Water Productivity in Seno and Yatenga Provinces of Burkina Faso Tunde Adegoke Amole 1*, Adetayo Adekeye 1 and Augustine Abioye Ayantunde 2 1 International Livestock Research Institute, Ibadan, Nigeria, 2 International Livestock Research Institute, Dakar, Senegal The expected increase in livestock production to meet its increasing demand could lead to increased water depletion through feeds production. This study aimed at estimating the amount of water depletion through feeds and its corresponding productivity in livestock within the three dominant livestock management systems namely sedentary-intensive, sedentary-extensive, and transhumance in Yatenga and Seno provinces in the Sahelian zone of Burkina Faso. Using a participatory rapid appraisal and individual interview, beneficial animal products, and services were estimated, and consequently, livestock water productivity (LWP) as the ratio of livestock products and services to the amount of water depleted. Our results showed feed resources are mainly natural pasture and crop residues are common in all the management Edited by: Yaosheng Wang, systems though the proportion of each feed type in the feed basket and seasonal Chinese Academy of Agricultural preferences varied. Consequently, water depleted for feed production was similar across Sciences, China the systems in both provinces and ranged from 2,500 to 3,200 m−3 ha−1 yr−1. Values Reviewed by: Katrien Descheemaeker, for milk (40 US$US$/household) and flock offtake (313 US$/household) derived from Wageningen University and the transhumant system were higher (P < 0.05) than those from other systems in the Research, Netherlands Seno province. -
(Poaceae: Paniceae), with Lectotypification of Panicum Divisum
Phytotaxa 181 (1): 059–060 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2014 Magnolia Press Correspondence ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.181.1.5 A new combination in Cenchrus (Poaceae: Paniceae), with lectotypification of Panicum divisum FILIP VERLOOVE1, RAFAËL GOVAERTS2 & KARL PETER BUTTLER3 1Botanic Garden of Meise, Nieuwelaan 38, B-1860 Meise, Belgium [[email protected]] 2Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AE, England [[email protected]] 3Orber Straße 38, D-60386 Frankfurt am Main, Germany [[email protected]] Abstract The new combination, Cenchrus divisus (J.F. Gmelin) Verloove, Govaerts & Buttler, is proposed for the species widely known as Pennisetum divisum (J.F. Gmelin) Henrard, and a lectotype for Panicum divisum J.F. Gmelin is designated. Key words: Cenchrus, lectotypification, nomenclature, Panicum As a result of recent molecular phylogenetic studies the generic boundaries of Cenchrus L. and related genera have considerably changed. Donadio et al. (2009) found that Cenchrus and Pennisetum Rich. are very closely related and demonstrated that most species of Cenchrus are in fact nested in Pennisetum. Chemisquy et al. (2010) confirmed these results and recommended merging both genera. The generic name Cenchrus having priority, all species of Pennisetum needed to be transferred to Cenchrus. Morrone (in Chemisquy et al., 2010) published new combinations in Cenchrus for most of the species and Symon (2010) made some additional name changes for a few Australian taxa. The correct names in Cenchrus for all but one of the 15 Pennisetum species in Europe and the Mediterranean area, including four new combinations, were given in Verloove (2012). -

CONTRIBUTIONS FROM THE United States National Herbarium Volume XII, Part 3 TXE&3 OF AMERICAN GRASSES . / A STUDY OF THE AMERICAN SPECIES OF GRASSES DESCRIBED BY LINNAEUS, GRONOVIUS, SLOANE, SWARTZ, AND MICHAUX By A. S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations. -

Published Vestigations Together Study Existing Accept Arrangements
Notes on the Nomenclature of some grasses II by Dr. J.Th. Henrard (Rijksherbarium, Leiden) (Issued September 10th, 1941). In a former article new combinations and critical observa- 1) many all the world. New in- tions were published on various grasses over vestigations in critical genera together with the study of the existing literature made it necessary to accept various other arrangements in this important family. The old system of Bentham, once the basis for a total is and modified and review, now more more many tribes are and limited. The have purified more exactly most recent system we at the moment, is Hubbard’s treatment of this family in the work of Hutchinson: The families of flowering plants. Vol. II. Monocotyle- dons. The grasses are divided there into 26 tribes. We have here the great advantage that aberrant which are into genera, not easy to place one of the formerly accepted tribes, are given as representatives of distinct new tribes. The curious tropical genus Streptochaeta f.i. con- stitutes the tribe of the Streptochaeteae. It is quite acceptable that tribes consist of but may one genus, especially when such a genus is a totally deviating one and cannot be inserted into one of the already existing ones. Such tribes are f.i. the Nardeae with the only northern genus Nardus, and the Mediterranean tribe of the Lygeeae with the only genus Lygeum, one of the Esparto grasses. It is therefore wonder no that Hubbard creates a new tribe, the Anomochloeae, for one of the most curious tropical grasses of the world. -

Garten, Wissenschaft & Pädagogik, Siesmayerstr. 61, 60323 Frankfurt am Main, Germany Abstract. We combined grass (Poaceae) occurrence data from the Sahelian parts of Burkina Faso, West Africa, with data on the photosynthetic type of these species. Occurrence data were compiled from relevés and collections of the Herbarium Senckenbergianum, and the assignment of photosynthetic types was taken from the literature and completed by leaf ana- tomical observations of our own. We used the occurrence data to model species distributions using GARP (Genetic algo- rithm of rule-set production) and high-resolution satellite data (Landsat ETM+) as environmental predictors. In a subse- quent step we summarized the distributions of single species for each photosynthetic type. The resulting distribution patterns reflect the ecological preferences connected with photosynthetic pathways. The only C3 species is strictly bound to watercourses and temporary lakes, C4 MS species mainly occur on the dunes, C4 PS-PCK species are mainly from dunes and watercourses, C4 PS-NAD type species dominate the drier peneplains. -
