Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette
Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette
Green Canyon Environmental Research Area, Logan Utah
Despite their temperate to subarctic geographic range, American martens (Martes americana) possess a thermally inefficient morphology. The lack of morphological adaptations for reducing thermal costs suggests that marten may use behavioral strategies to optimize thermal budgets. During the winters of 1989-1990 and 1990-1991, we radio-collared and monitored the diel activity of 7 martens. A log-linear model suggested that the presence or absence of light was the only factor associated with marten activity patterns (p < 0.001). A regression of the percentage of active fixes on ambient temperature failed to detect an association (b = -4.45, p = 0.084, n = 12). Contents of marten seats suggested that their activity was consistent with the prey-vulnerability hypothesis. While martens must balance multiple life requisites, their activity patterns suggest that they accept increased thermal costs in order to increase foraging efficiency. However, the nocturnal activity of martens during winter was also consistent with the hypothesis that they may be able to limit their own exposure to predation risk. The nocturnal habits of Newfoundland martens in the winter were consistent with the hypothesis of avoidance of predation risk.
Vertical, Longitudinal And Seasonal Variation In The Benthic Fauna At The Fernow Experimential Forest, Parsons, West Virginia, Robert William Hood
Vertical, Longitudinal And Seasonal Variation In The Benthic Fauna At The Fernow Experimential Forest, Parsons, West Virginia, Robert William Hood
Theses, Dissertations and Capstones
Multi-level basket samplers were placed within the shallow hyporheic zone (0 - 30 cm) of first through fourth-order streams in the Elklick Run drainage at the Fernow Experimental Forest, Parsons, West Virginia. Samplers were colonized by macroinvertebrates over three month intervals and collected during three different seasons. Seasonal, longitudinal, and vertical variation in the macroinvertebrate assemblage were examined to better understand the structure and function of the interstitial macroinvertebrate assemblage and important underlying factors. Surber samples were collected for comparison between surface and hyporheic macroinvertebrate assemblages. Temperature, dissolved oxygen, water chemistry, and interstitial water movement were measured at sampler locations. …
An Investigation Of The Acarine Fauna Of Rehabilitated Bauxite Mines In The Northern Jarrah Forest, Alex Cuccovia
An Investigation Of The Acarine Fauna Of Rehabilitated Bauxite Mines In The Northern Jarrah Forest, Alex Cuccovia
Theses : Honours
The northern jarrah forest relies on efficient nutrient cycling for its growth and long term sustainability. The decomposition of organic matter and the recycling of nutrients in such ecosystems are facilitated through the interaction of microflora with a myriad of invertebrates. The recolonisation of invertebrate fauna to rehabilitated bauxite mines is thus of critical importance to the long-term success of rehabilitation. This study investigated the soil and litter mite fauna, important components of the invertebrate community well known for their numerical dominance and high biodiversity. A spring sampling of the mite fauna was undertaken, employing standard soil and litter sampling …
Effects Of Retained Pine And Hardwood Basal Areas On Percent Cover Of Plants Utilized By Bobwhite Quail, David G. Peitz, Philip A. Tappe, Michael G. Shelton
Effects Of Retained Pine And Hardwood Basal Areas On Percent Cover Of Plants Utilized By Bobwhite Quail, David G. Peitz, Philip A. Tappe, Michael G. Shelton
Journal of the Arkansas Academy of Science
Percent cover of seven forage species utilized by bobwhite quail (Colinus virginianus) was determined before thinning and 2 and 4 years after thinning a 35-year-old loblolly pine-hardwood stand. Combinations of three loblolly pine (15, 18, and 21 m2/ha) and three hardwood (0, 3.5, and 7 m2/ha) basal areas were replicated three times. Percent cover was determined for American beautyberry (Callicarpa americana), blackberry (Rubus spp.), tick trefoil (Desmodium spp.), lespedeza (Lespedeza spp.), panic grass (Panicum spp.), yellow wood sorrel (Oxalis stricta), and three-seeded mercury (Acalypha spp.). Percent cover of American beautyberry and blackberry increased with time. Tick trefoil and panic grass …

Variability In Forest Floor Mass And Nutrient Concentration Of Mature Pine-Hardwoods In The Ouachita Mountains, Hal O. Liechty, Michael G. Shelton, Edwin R. Lawson
Variability In Forest Floor Mass And Nutrient Concentration Of Mature Pine-Hardwoods In The Ouachita Mountains, Hal O. Liechty, Michael G. Shelton, Edwin R. Lawson
Journal of the Arkansas Academy of Science
Prior to timber harvesting, forest floor mass and nutrient concentrations in forest floor and mineral soil were determined in 24 mature, shortleaf pine (Pinus echinata Mill.)-hardwood stands occurring within the northern, eastern, southern and western sub-ecoregions of the Ouachita Mountains. The forest floor samples were collected at each of three locations representing the lower, mid, and upper slope positions within each stand. Samples of the L-(litter) and F-layers (fermentation) were collected separately. Materials from the L-layer were differentiated into hardwood foliage, pine foliage, and woody/reproductive components. Mass and nutrient concentrations of the various forest floor components were compared among slope …
Summer Home Range Size Of The Eastern Cascade Mountain Beaver (Aplodontia Rufa Rainieri) In Relation To Availability Of Preferred Food, Robert Julian Stagg
Summer Home Range Size Of The Eastern Cascade Mountain Beaver (Aplodontia Rufa Rainieri) In Relation To Availability Of Preferred Food, Robert Julian Stagg
All Master's Theses
Optimal foraging theories relate food preference to nutrient content and nutrient availability to home range size. After synthesizing these theories, I hypothesized that the availability of preferred food plants influences the home range size of generalist herbivores. I also hypothesized that the availability of preferred foods does not affect weight gain of time-minimizing generalist herbivores, but should affect the weight gain of energy-maximizing generalist herbivores. To test these hypotheses, I studied the home ranges, weights, weight gains, food habits, and habitats of six adult female mountain beavers (Aplodontia rufa) from six separate sites where bracken fern was either …
