PLAGUE STUDIES * 6. Hosts of the Infection R
Bull. Org. mond. Sante 1 Bull. World Hlth Org. 1952, 6, 381-465 PLAGUE STUDIES * 6. Hosts of the Infection R. POLLITZER, M.D. Division of Epidemiology, World Health Organization Manuscript received in April 1952 RODENTS AND LAGOMORPHA Reviewing in 1928 the then rather limited knowledge available concerning the occurrence and importance of plague in rodents other than the common rats and mice, Jorge 129 felt justified in drawing a clear-cut distinction between the pandemic type of plague introduced into human settlements and houses all over the world by the " domestic " rats and mice, and " peste selvatique ", which is dangerous for man only when he invades the remote endemic foci populated by wild rodents. Although Jorge's concept was accepted, some discussion arose regarding the appropriateness of the term " peste selvatique" or, as Stallybrass 282 and Wu Lien-teh 318 translated it, " selvatic plague ". It was pointed out by Meyer 194 that, on etymological grounds, the name " sylvatic plague " would be preferable, and this term was widely used until POzzO 238 and Hoekenga 105 doubted, and Girard 82 denied, its adequacy on the grounds that the word " sylvatic" implied that the rodents concerned lived in forests, whereas that was rarely the case. Girard therefore advocated the reversion to the expression "wild-rodent plague" which was used before the publication of Jorge's study-a proposal it has seemed advisable to accept for the present studies. Much more important than the difficulty of adopting an adequate nomenclature is that of distinguishing between rat and wild-rodent plague- a distinction which is no longer as clear-cut as Jorge was entitled to assume. -
Implications of Climate Change for Food-Caching Species
Demographic and Environmental Drivers of Canada Jay Population Dynamics in Algonquin Provincial Park, ON by Alex Odenbach Sutton A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Alex O. Sutton, April 2020 ABSTRACT Demographic and Environmental Drivers of Canada Jay Population Dynamics in Algonquin Provincial Park, ON Alex Sutton Advisor: University of Guelph, 2020 Ryan Norris Knowledge of the demographic and environmental drivers of population growth throughout the annual cycle is essential to understand ongoing population change and forecast future population trends. Resident species have developed a suite of behavioural and physiological adaptations that allow them to persist in seasonal environments. Food-caching is one widespread behavioural mechanism that involves the deferred consumption of a food item and special handling to conserve it for future use. However, once a food item is stored, it can be exposed to environmental conditions that can either degrade or preserve its quality. In this thesis, I combine a novel framework that identifies relevant environmental conditions that could cause cached food to degrade over time with detailed long-term demographic data collected for a food-caching passerine, the Canada jay (Perisoreus canadensis), in Algonquin Provincial Park, ON. In my first chapter, I develop a framework proposing that the degree of a caching species’ susceptibility to climate change depends primarily on the duration of storage and the perishability of food stored. I then summarize information from the field of food science to identify relevant climatic variables that could cause cached food to degrade. -

Differential Effects of Fire on Small Mammal Communities in the Busanga Flood Plain, Zambia
Research Article Tropical Conservation Science Volume 10: 1–13 Differential Effects of Fire on Small Mammal ! The Author(s) 2017 Reprints and permissions: Communities in the Busanga Flood Plain, sagepub.com/journalsPermissions.nav DOI: 10.1177/1940082917725439 Zambia journals.sagepub.com/home/trc Ngawo Namukonde1,2, Daniel Kuebler3, and Jo¨rg U. Ganzhorn1 Abstract We assessed effects of vegetation and fire on small mammals in open vegetation formations of the Busanga Flood Plain (Kafue National Park, Zambia) in areas of low and high fire recurrence. The impact of fire was related further to the time elapsed between the last fire and the time of trapping (fire age). Sampling sites covered three management zones: intensive utilization (tourist areas), wild (less used), and wilderness (no road access). Vegetation type, fire recurrence, fire age, and management zone were independent variables. Communities were similar in grassland and on termitaria but differed from miombo. Species richness was highest on termitaria, followed by grassland and miombo. Species numbers declined with increasing fire frequency but were unaffected by fire age. In contrast, the average body mass of species occurring at any one site (only adult individuals considered) declined with the time elapsed between the time of capture and the last fire (the longer the time interval, the lower the body mass of species averaged over the species found at the site). This response implies higher vulnerability of the smaller species to fire and slower recolonization potential of smaller species after fire. The interactions between fire, vegetation characteristics, and small mammals need to be reviewed, given their importance in the functionality of this ecosystem. -

Schlitter, Ph.D. Chairperson Vice President for Research and Dean of Graduate Studies Date: October 24, 2008 Abstract Molecular and paleontological approaches have produced extremely different estimates for divergence times among orders of placental mammals and within rodents with molecular studies suggesting a much older date than fossils. We evaluated the conflict between the fossil record and molecular data and find a significant correlation between dates estimated by fossils and relative branch lengths, suggesting that molecular data agree with the fossil record regarding divergence times in rodents. -

On Mammalian Sperm Dimensions J
On mammalian sperm dimensions J. M. Cummins and P. F. Woodall Reproductive Biology Group, Department of Veterinary Anatomy, University of Queensland, St Lucia, Queensland4067, Australia Summary. Data on linear sperm dimensions in mammals are presented. There is infor- mation on a total of 284 species, representing 6\m=.\2%of all species; 17\m=.\2%of all genera and 49\m=.\2%of all families have some representation, with quantitative information missing only from the orders Dermoptera, Pholidota, Sirenia and Tubulidentata. In general, sperm size is inverse to body mass (except for the Chiroptera), so that the smallest known spermatozoa are amongst those of artiodactyls and the largest are amongst those of marsupials. Most variations are due to differences in the lengths of midpiece and principal piece, with head lengths relatively uniform throughout the mammals. Introduction There is increasing interest in comparative studies of gametes both from the phylogenetic viewpoint (Afzelius, 1983) and also in the analysis of the evolution of sexual reproduction and anisogamy (Bell, 1982; Parker, 1982). This work emerged as part of a review of the relationship between sperm size and body mass in mammals (Cummins, 1983), in which lack of space precluded the inclusion of raw data. In publishing this catalogue of sperm dimensions we wish to rectify this defect, and to provide a reference point for, and stimulus to, further quantitative work while obviating the need for laborious compilation of raw data. Some aspects of the material presented previously (Cummins, 1983) have been re-analysed in the light of new data. Materials and Methods This catalogue of sperm dimensions has been built up from cited measurements, from personal observations and from communication with other scientists. -

The Effect of Habitat Type on Rodent, Shrew and Sengi Species
THE EFFECT OF HABITAT TYPE ON RODENT, SHREW AND SENGI SPECIES ABUNDANCE, RICHNESS, DIVERSITY AND COMPOSITION AT FARM KARACHAS, OUTJO, NAMIBIA A RESEARCH THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE (BIODIVERSITY MANAGEMENT AND RESEARCH) OF THE UNIVERSITY OF NAMIBIA BY SALMI KAPALA 201201786 APRIL 2021 SUPERVISOR: Prof. John K. Mfune (University of Namibia) ABSTRACT Natural habitats have been fragmented by many human activities including farming, hence affecting vegetation structure. Despite being very dry, Namibia has many farms in which game, livestock and crop farming are practiced. Yet such activities affect populations of many other organisms including small mammals such as rodents, shrews and sengis. The present study investigated the effect of habitat type on rodent, shrew and sengi species abundance, richness, diversity and composition in selected open grassland habitat and woody habitats at Karachas Farm, Outjo, Namibia. Sampling at each habitat type was replicated twice. Woody plant species abundance, composition, height and percentage grass cover were determined and compared between the open grassland and woody habitats. A capture-mark-recapture (CMR) technique was employed to obtain data on rodents, shrews and sengis. Each habitat type was sampled over five consecutive nights using Sherman live traps. The result of t-, chi-square and Mann-Whitney tests, respectively, showed a statistically significant difference in the mean abundance of woody plants, plant height, and plant species richness between the open grassland and woody habitats. A Mann-Whitney test showed no statistically significant difference in the percentage grass cover between the open grassland and woody habitats.
