The Challenger Scallop Enhancement Company is a fishery self-governing organisation based around Individual Transferable Quota (ITQ) property rights. The Company has direct responsibility for managing New Zealand’s largest scallop (Pecten novaezelandiae) fishery known as the Southern Scallop Fishery and is contracted to manage several others. The management framework in the...
This thesis presents a linear programming package that uses an
algorithm and data storage method efficient enough to solve a medium
sized linear programming problem (250 variables and 100 constraints)
on a minicomputer with small core memory space (4000 bytes).
In this routine the problem is formulated by the use...
Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...
The western Nearctic species of the genus Phytocoris Fallen were
taxonomically revised. Over 15,000 specimens were examined.
Information concerning host plant associations and distributions was
compiled and summarized for use by future researchers. External
morphological features and characters of the male genitalia were used
to distinguish species. The genital tubercles...
This thesis investigates how beginning, women farmers, within in a women farmers’ network in the Willamette Valley, Oregon are accessing land and farming information. Using ethnographic, community-based research methods, I ask how land access mediates their ability to care for their land and soil. Are these farmers interested in fostering...
This study was commissioned and funded by the Coastal Oregon Marine Experiment Station (COMES) to 1) identify the scientific and management issues constraining the advancement of the Oregon bay clam commercial industry, 2) explore scientific, management, and economic opportunities for the enhancement of the fishery, 3) outline and suggest mechanisms...
Identification and population counts of soil mesofauna can be an
important tool for soil ecologists to determine the soil biodiversity. Information
provided from population counts can give insight to soil ecologists about the
effects of human land use, monitoring soil and water health, benefits of soil
biodiversity in agriculture, and...
There are more than 87,000 chemicals in current use with little to no toxicity information available. Assessing such a large number of chemicals using traditional methods would take an unreasonable amount of time and money, and require the use a large number of animals. The incorporation of high-throughput in vivo...
Small-scale fisheries (SSF) around the world face many challenges. They are a highly dynamic, important sector for coastal communities in developing nations, playing a critical role in poverty alleviation and food security. SSFs generally have few resources to ensure their long-term sustainability. They are often fished and managed locally and...
AIM:
Meta-community structure is a function of both local (site-specific) and regional (landscape-level) ecological factors, and the relative importance of each may be mediated by the dispersal ability of organisms. Here, we used aquatic invertebrate communities to investigate the relationship between local and regional factors in explaining distance decay relationships...
