Small mammal pollination in Protea Witzenbergiana
… as to whether it is pollinated by small mammals. This study investigated whether the plant is rodent-pollinated, and if so to what extent by various species. Fieldwork was carried out over three days of live trapping, during and after the flowering season. Exclosure experiments were set …

Community ecology of small-mammal pollinated proteas
The floral characteristics of small-mammal pollinated (SMP) Protea species have been assessed in a number of previous studies. This study aimed to determine whether the inflorescences of Protea canaliculata, Protea sulphurea and Protea humiflora possess these traits and are pollinated by small …

Small Mammal Survey of Wind Cave National Park
… years old, during this time no parkwide small mammal survey has been conducted. The purpose of this research project was to conduct a biodiversity survey of the small mammal community that inhabits WCNP. For this study, small mammals are defined as those mammals which weigh less than 4.54 kg (1 …

Mammal Distributions and Habitat Models for South Dakota
… distribution maps and habitat models for the mammals of South Dakota; (2) conduct expert review of these maps and models; (3) create species richness maps; and (4) perform gap analysis of habitat models. Due to a lack of small mammal data, trapping surveys were implemented in 1998, and data …

Modeling and frequency tracking of marine mammal whistle calls
Marine mammal whistle calls present an attractive medium for covert underwater communications. High quality models of the whistle calls are needed in order to synthesize natural-sounding whistles with embedded information. Since the whistle calls are composed of frequency modulated harmonic tones, …

Drift modelling of marine mammal carcases in coastal waters
… I develop a drift modelling framework for marine mammal carcases in coastal waters. The resulting models were run forwards and backwards in time to provide insights into strategies for environmental monitoring under two scenarios. The first explored the beach search options for carcases resulting …

Small Mammal Habitat Associations in a Fragmented Agricultural Landscape
… of this research was to examine how small mammals select habitats in a fragmented agricultural landscape in southeast Georgia. I captured small mammals at 71 trap sites within 33 locations in Bulloch and Candler Counties, Georgia. Prior to trapping, each site was classified based on …

Passive Acoustics: A Multifaceted Tool for Marine Mammal Conservation
<p>Marine mammals exploit the efficiency of sound propagation in the marine environment for essential activities like communication and navigation. For this reason, passive acoustics has particularly high potential for marine mammal studies, especially those aimed at population management and …

Small mammal demographics in North Dakota conservation reserve program plantings
… methods were used to de~ermine small mammal demographics and population dynamics in Conservation Reserve Program (CRP) plantings in north central North Dakota. Four age classes (1-4 years) of CRP plantings were sampled. Small mammal species diversity was low (H'=0.057-0.374). Eight …

Metabolism and Handling of Folates in the Mammal Especially Man
The metabolism of oral administered folates and their handling has been studied in humans. Aseptic addition methods of microbiological assay with L.casei, S.faecalis, P.cerevisiae and bioautographic techniques were employed in investigations of serum and urine folates. Studies of normal human serum …

Multiscale patterns of mammal diversity and occurrence in the Karoo
… evaluates the distribution and ecology of the mammalian (>0.5kg) community across the Karoo, with a focus on developing potential methods that can effectively record both common and rare species. My primary aim was to understand how biophysical drivers and intraguild interactions have shaped …

Small mammal use of abandoned surface mines in southwestern Virginia
… of 1976 to determine relationships between small mammal diversity and abundance and select vegetation and site factors. Eleven species of mammals were captured during four, six-night trapping periods. Peromyscus leucopus noveboracensis and P. maniculatus nubiterrae were the most abundant and …

Genetically based social communication in an inbred group-living wild mammal
… basis of chemical communication in a social mammal, the banded mongoose. Banded mongooses are prolific scent markers that use secretions from different organs to communicate both within and between groups, as well as intra- and intersexually. Their exceptional breeding system, cooperative …

Mammal Damage and Movements of Deer Mice in South Dakota Shelterbelts
<p>A study was initiated to examine animal damage to new shelterbelts in Brookings County, South Dakota. Feeding preferences of deer mice (Peromyscus maniculatus) prairie voles (Microtus ochragaster), and cottontail rabbits (Sylvilagus floridanus) was conducted on 5 woody species that colIIIllonly …

Scrimshaw: unlocking the cultural and biological archive of sea mammal art
During the middle decades of the nineteenth century the folk-art tradition ‘scrimshaw’, predominantly using the teeth of sperm whales (Physeter macrocephalus), flourished among the crews of industrial whaling ships. Scrimshaw collections represent a unique cultural and biological archive of …
