Understory response to tree harvesting in pinyon-juniper woodlands

Creator:

Everett, Richard L.

Abstract:

Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

Test method to determine the degree of asphalt stripping from aggregates

Creator:

Boudreau, Richard L.

Abstract:

Moisture damage has long been recognized as one of the most critical factors influencing the performance of asphalt concrete (AC) pavements. This moistureinduced damage occurs from either the physical separation of the asphalt film from the aggregate or the softening of the asphalt binder within the AC mixture in the...

Model III : a sequential approach to joint optimization of the stand treatment and forest level harvest scheduling problem

Creator:

Barber, Richard L.

Abstract:

Harvest scheduling and stand level optimization have generally been regarded as separable problems. Some studies have attempted to jointly optimize a wide range of stand treatments and a forest wide harvest schedule using combinations of mathematical programming techniques. The mathematical programming forest level techniques presume perfect information on production, costs...

Behavioral and demographic characteristics of northern sea lion rookeries

Creator:

Merrick, Richard L.

Abstract:

Northern sea lions (Eumetopias lubatus) were studied at three sites (Rogue Reef, Oregon, Marmot Island, Alaska, and T.Ugamak Island, Alaska) during the 1982, 1983, 1985, and 1986 breeding seasons. Data were collected on female activity budgets, attendance patterns, births, copulations, population structure, and patterns of seasonal and daily abundance. Females...

Further Evidence for Coastal Trapped Waves along the Peru Coast

Creator:

Romea, Richard D. and Smith, Robert L.

Abstract:

Time series of coastal sea level during 1976–77, from 2°12′S to 17°S along the west coast of South America, show that low-frequency, ω < 0.25 cycles per day (cpd), fluctuations propagate poleward with the phase speed of baroclinic Kelvin waves (2–3 m s⁻¹). The alongshore coherence is highest in the...
