AbstractSeasonal abundance of fleas infesting small mammals was studied from July 1975 to August 1976 in a grassland in Lake Nakuru National Park, Kenya. Ten species of rodents and two species of shrews were live-trapped 935 times. The Nile grass rat (Arvicanthis niloticus) was the most abundant species, with 233 individuals captured 690 times, forming 73·8% of all captures. From these grass rats, 4247 fleas were collected, including Dinopsyllus lypusus Jordan & Rothschild (n = 2596), Xenopsylla bantorum Jordan (n = 1396) and Ctenophthalmus calceatus cabirus Jordan & Rothschild (n = 255). D. lypusus and C. calceatus cabirus were more abundant on Nile grass rats during the rains, while ×. bantorum became more abundant during the dry season and peaked during the early part of the rains. The potential for plague transmission by fleas between Nile grass rats probably exists all year. The potential for transmission to people living in close proximity to these rodents may be highest during the seasonal peak of X. bantorum, at the end of the dry season.

ABSTRACTA total of 392 small mammals belonging to five species of small rodents and four species of shrews were caught. The small mammals and their percentage composition were Crocidura nigeriae (20.9%), Crocidura grandiceps (11.7%), Crocidura crossei (9.7%), Crocidura flavescens manni (20.4%), Mus musculoides (39.0%), Praomys tullbergi (11.5%), Lophuromys sikapusi (3.6%), Lemniscomys striatus (1.3%), and Arvicanthis niloticus (0.3%).There were monthly variations in the number of Mus musculoides and Crocidura nigeriae.In Mus musculoides breeding was at a maximum at the beginning and towards the end of the wet season and early dry season. In Crocidura nigeriae breeding was maximal during the wet season and low in the dry season.The seasonal changes in the age structure of the two most common species: Mus musculoides and Crocidura nigeriae, are described.

Megalothorax minimus (Neelidae) and Sphaeridia pumilis (Sminthurididae) had already been identified in surface sampling from Sierra de Guadarrama. In Europe, Sminthurinus gisini (Katiannidae) seems to be associated with environments at specific altitudes, and has little representation in this sampling. Pygmarrhopalites custodum Baquero and Jordana sp. nov. (Arrhopalitidae) coexists with two previously identified surface occurring species of the same family (P. elegans and Arrhopalites caecus). However, P. custodum is more abundant, indicating that it occupies an ecological niche tending to troglophile in the mesovoid shallow substratum (MSS). Moreover, it is also more abundant in the MSS of higher altitude corresponding to the bioclimatic zones cryo-oro-Mediterranean and oro-Mediterranean supra forest. Allacma cryptica Baquero and Jordana sp. nov. (Sminthuridae), is another species that had not been previously detected on the surface in the study area. A. cryptica is an addition to a genus which has eight described species. Gisinurus malatestai (Sminthuridae) appears well represented in the MSS, being a species present very occasionally in the Mediterranean area. Two species of the genera Sminthurides (Sminthurididae) and Fasciosminthurus (Bourletiellidae) have been found, but they could not have been identified to the species level. Finally, a few specimens of Dicyrtomina minuta (Dicyrtomidae), an abundant species on the surface, have been captured.

Two years have passed since Colonel J. A. B. Sandenbergh, the Warden of the Kruger National Park, launched a public appeal to provide water for the wild life of the park. Subscriptions were invited for two purposes: the first to provide boreholes so that in the dry season animals could find water within reach of their grazing, the second to form a general fund to build dams to retard the run-off of rain water.

The 1991/92 drought in Southern Africa and the effect of the resultant reduced flow of the Sabie River on hippopotami was investigated. Hippopotami are counted annually in the Kruger National Park's (KNP) major rivers as part of the park's monitoring pro- gramme. Two additional aerial surveys were conducted to document changes in hippopotamus population densities in the Sabie River during the drought period. The hippopotamus population decreased during the drought by 12.6 to 672 animals between July 1991 and October 1992. The highest and lowest hippopotamus densities recorded were 11.6 and 2.2 animals/km river length respectively in different river sections. Only 12 hippopotamus mortalities were recorded at the end of the 1992 dry season (October).

A survey of the small mammals of the Addo Elephant National Park resulted in a checklist, as well as information on relative numbers, distribution within the Park, reproductive activity, sex ratios, and body measurements. Forty mammals species occur in the Park, while three re-introduced species probably do not occur any longer. Of the 40 species 28 are considered small mammals comprising 13 rodent, eight carnivore, two shrew, two bat, one primate and one lagomorph species, as well as the aardvark: Crociduraflavescens, C. cyanea infumata, Rousettus aegyptiacus, Eptesicus capensis, Cercopithecus pygerythrus, Canis mesomelas, Ictonyx striatus, Poecilogale albinucha, Genetta sp., Herpestes pulverulentus, Suricata suricatta, Proteles cristatus, Felis caracal, Orycteropus afer, Lepus saxatilis, Cryptomys hottentotus, Hystrix africae-australis, Pedetes capensis, Graphiurus murinus, Aethomys namaquensis, Praomys natalensis, Rhabdomys pumilio, Mus minutoides, Rattus rattus, Saccostomys campestris, Desmodillus auricularis, Otomys irroratus and 0. unisulcatus.

The species composition and abundance of adult caddisflies attracted to the illuminated showcase of a vending machine set along the middle reaches of the Shinano River were investigated every Sunday night from April to November in 2005 to 2007. A total of 1,405 adult caddisflies was collected during the investigation periods. We identified a total of 13 species belonging to 11 genera of 8 families. The most abundant species was Psychomyia acutipennis (Ulmer 1908) each year. Psychomyia acutipennis adults were collected from mid-May to the beginning of October (the range of mean air temperature was 13.8 to 27.7°C), with its seasonal abundance divided into several peaks, i.e., the end of May, the beginning of June, and the end of August to the beginning of September in both 2006 and 2007. On the other hand, in 2005 when there was no large-scale summer flood and there were no marked abundance peaks. The present study suggests that the mean air temperature and summer floods impacted the seasonal abundance of P. acutipennis adults.

Sylvatic plague (Yersinia pestis) and tularemia (Francisella tularensis) are infectious bacterial diseases that can be transmitted from wild mammals to humans by insects or through direct contact. Although cases of plague and tularemia have been reported in the southwest, a comprehensive understanding of the prevalence, distribution and dynamics of these diseases is lacking. During the months of June and July 2000 we sampled small mammals in Grand Teton National Park (GTNP) for antibodies of these zoonotic diseases. This survey was conducted in conjunction with a large scale population dynamics study, lead by Dr. Brian Miller, Denver Zoological society, and Dr. Hank Harlow, Department of Zoology and Physiology, University of Wyoming. A published survey of plague and tularemia has not been conducted in GTNP. In 1996, Dr. Fredrick Jannett looked for plague in the genus Microtus and found low incidence

Specifically, the objectives of this research project were to: 1) Census burned and unburned grassland areas for breeding populations of birds and small mammals. Population censuses have been made on areas prescribed burned between 1973 and 1978 as well as the areas burned in the spring of 1981; 2) Analyze study transect vegetation to determine the impact of burning treatments on prairie vegetation and its relationship to bird and small mammal densities; 3) Provide usable management recommendations that will aid not only in vegetation maintenance but also with the animal populations associated with the grasslands.
