Mp745: A Long-Term Study Of An Oak Pine Forest Ecosystem: A Brief Overview Of The Holt Research Forest, Jack W. Witham, Malcolm L. Hunter Jr., Hollis C. Tedford Iii, Alan J. Kimball, Alan S. White, Susan Elias Gerken

Miscellaneous Publications

This publication provides an overview of the long-term forest ecosystem project at the Holt Research Forest in Arrowsic, Maine. It is based on nearly 16 years of work by an interdisciplinary team from the College of Natural Sciences, Forestry, and Agriculture, including faculty, professional staff, visiting scientists, University of Maine graduate students, and undergraduate field assistants. We hope this publication will be useful to other researchers, to our workshop participants, and to others interested in forest ecosystem science.

Ecology Of The Malay Civet (Viverra Tangalunga) In A Logged And An Unlogged Forest In Sabah, East Malaysia, Christina P. Colon

Publications and Research

Malay civets in a dipterocarp rain forest were studied from December, 1995, through June, 1997, in the Ulu Segama Forest Reserve in Sabah, East Malaysia. To investigate the basic ecology of this species and explore the potential impact of selective logging, data on home range, activity and diet were collected on study animals in an unlogged and a selectively logged forest, and comparisons made.

Density in the unlogged forest was 1/0.46 km² , and 1/1.07 km² in the logged forest. Mean home range size based on a 95% minimum convex polygon was 110 ha. and did not differ …

Acorn Foraging As A Means To Explore Human Energetics And Forge Connections To Local Forests, Jeffrey J. Gerwing, Pamela Lockwood, Christopher Uhl

Environmental Science and Management Faculty Publications and Presentations

Jeffrey Gerwing, Pamela Lockwood, and Christopher Uhl describe a rather unusual ecology laboratory/field exercise that utilizes abundant oak habitats of central Pennsylvania. For those readers not blessed with an abundant supply of oaks nearby, perhaps other species could be substituted. The exercise is unusual in two ways. It offers a new undergraduate ecology activity, and it offers opportunities for students to relate other disciplines to their science course.

In "the good old days" of higher education each discipline offered its menu of courses and expected students to make appropriate connections among the courses of their major, minor, and general education. …

Functional Success Of Six Constructed Bottomland Hardwood Forests In Central And Western Kentucky, Ryan W. Mccall

Morehead State Theses and Dissertations

A thesis presented to the faculty of the College of Science and Technology Morehead State University in partial fulfillment of the requirements for the Degree of Master of Science by Ryan W. McCall on January 25, 1999.

Green Canyon Recreation Management Plant, Jesse Evans, Erin Haddock, Todd Tibbetts, Lindsey Topham

Green Canyon Environmental Research Area, Logan Utah

The purpose of this plan is to look at the way Green Canyon is currently being managed and make recommendations for management based on our findings. Prior to this document, a Landscape Assessment was conducted on Green Canyon. This plan incorporates that assessment but focuses on the recreation management of the canyon. We will discuss history, current management, social conditions, purpose and need, as well as methods we used to go about gathering information. The focus is to identify key issues and concerns within the canyon. Management recommendations will be made based on the issues and concerns identified.

The Effect Of Proximity On Landmark Use In Clark’S Nutcrackers, Kristy L. Gould-Beierle, Alan Kamil

Avian Cognition Papers

Clark’s nutcrackers, Nucifraga columbiana, store thousands of pine seeds during the autumn and retrieve them throughout the winter. It has been shown that these birds are able to use visual cues to relocate hidden food in the laboratory. In this set of experiments, we trained three groups of Clark’s nutcrackers to find a hidden food goal that was placed in the same spatial location relative to the testing room. During training, the location of two local cues in relation to the goal differed between the three groups. Group 1 learned the task with the cues closest to the goal, group …

Patterns Of Movement And Orientation During Caching And Recovery By Clark’S Nutcrackers, Nucifraga Columbiana, Alan Kamil, Russell P. Balda, Sally Good

Avian Cognition Papers

Clark’s nutcrackers regularly store large numbers of pine seeds and remember the locations of the cached seeds. Although they are very accurate, they do make some errors during recovery. In an attempt to determine whether any behaviours during caching predicted the occurrence of errors during recovery, we videotaped Clark’s nutcrackers while they cached and recovered seeds under laboratory conditions. We used the videotapes to develop complete, quantitative descriptions of caching and recovery behaviour, with an emphasis on body orientation and directions of movement. During caching, the birds showed the greatest change in their orientation and direction following cache creation. During …

How Do They, Indeed? A Reply To Biegler Et Al., Alan Kamil, Juli E. Jones

Avian Cognition Papers

We trained Clark’s nutcrackers, Nucifraga columbiana, to search halfway between two landmarks while varying the distance between the landmarks (Kamil & Jones 1997). We found that the birds learned the problem readily and generalized to novel interlandmark distances within the range of distances used during training. Unlike some other studies in which responses to proportional distance were obtained (e.g. O’Keefe & Burgess 1996; Tommasi et al. 1997), the nutcrackers showed very precise search and maintained this precision during the transfer test. The distributions of digging locations around the central position were concentrated within ±1–2 cm of the central location …
