A recent shift in the pattern of commercial harvest in the Keppel Island region of the southern inshore Great Barrier Reef raises concern about the depletion of a number of relatively rare restricted range taxa. The shift appears to be driven by demand from the United States (US) for corals for domestic aquaria. Data from the annual status reports from the Queensland Coral Fishery were compared...

We monitored 142 radiocollared adult (!1.0 yr old) white-tailed deer (Odocoileus virginianus) in 3 study areas of Massachusetts, USA, to estimate annual survival and mortality due to legal hunting. We then applied these rates to deer harvest information to estimate deer population trends over time, and compared these to trends derived solely from harvest data estimates. Estimated adult female s...

In this study, the harvest scheduling problem of a group of cane growers in Thailand is addressed. Each member in a group is required to consistently supply sugar cane to a mill for the entire harvest season. However, the current scheduling does not account for the time-variant cane production of each cane field, which leads to unequal opportunities for growers to harvest. A portion of growers ...

This paper proposes a virtual harvest-transmit model and a harvest-transmit-store model for amplify-andforward full-duplex relay (FDR) networks with power splittingbased simultaneous wireless information and power transfer. The relay node employs a battery group consisting of two rechargeable batteries. By switching periodically between two batteries for charging and discharging in two consecut...

Simulations testing the future impacts of harvest and climate change to the Hudson Bay marine ecosystem were created utilizing an existing Ecopath with Ecosim model (Hoover et al., in this issue). Building on past simulations depicting known changes to the region, a suite of future scenarios was constructed to include a variety of climate change and harvest levels. Previously identified ecosyst...

Kochia (Kochia scoparia L.), Russian thistle (Salsolatragus L.), and prickly lettuce (Lactuca serriola L.) are economically important weeds infesting dryland wheat (Triticum aestivum L.) production systems in the western United States. Those weeds produce most of their seeds post-harvest. The objectives of this study were to determine the ability of an optical sensor, installed for on-the-go me...

Partial forest harvesting is known to modify both above- and belowground resource availability and may result in direct and indirect stress to the residual trees as a result of machinery traffic and sudden changes in irradiance. We studied sugar maple (Acer saccharum Marsh.) trees in stands that had undergone a selection harvest 11 years before sampling to verify whether sudden increases in lig...

Almond harvest accounts for a significant amount of PM10 emissions in California each harvest season. This paper addresses the reduction of blower passes during the harvest from 3 to 1 as a possible mitigation measure. Ambient total suspended particulate and PM10 sampling was conducted at two orchards during harvest with alternating control and experimental treatments. Onsite meteorological dat...

Harvest access systems (forest roads, skid trails, and landings) account for 90% of the erosion and sedimentation during harvesting activities. A well-planned harvest access system can reduce the surface area disturbed by logging, thereby decreasing the potential for erosion and sedimentation. Most Best Management Practices (BMP) guidelines suggest that the area disturbed by the harvest access ...

We provide a multi-factor real option model for a single harvest and then for perpetual forest harvesting, which extends the Faustmann (1849) approach to infinite rotations with multi-factor uncertainty. We examine separately forest growth and timber prices (and eventually credits/penalties for CO2 uptake/release upon harvest), so the forester can focus on critical exogenous and partially endog...
