Last Interglacial Muir Point Formation, Vancouver Island, British Columbia in The Last? Interglaciation in Canada : Le dernier (?) interglaciaire au Canada.
This paper briefly summarizes current knowledge of the Muir Point Formation and discusses the significance of recent paleomagnetic information showing that the lower part of the formation has normal polarity.

The AA. surveyed 20 stream reaches in Northern California with riparian corridors dominated by broadleaved trees and found that a high proportion of wood jams had key pieces that were still living. Living wood was capable of serving as a key piece
for a wood jam at a smaller size than dead wood and had a greater influence on channel morphology. Due to living wood, the range of tree species and sizes that provide stable and functional in-stream large wood may be broader than previously described.
A leader in geomorphometry in the 1950's and '60's, the American geographer W.F. Wood published little in the open literature. His best known work was a numerical system of terrain description. This paper reviews Wood's many contributions and lists
Wood storage within the active zone of the dynamic, gravel-bed, Fiume Tagliamento, Italy, was investigated at 8 sites along the river's main stem. The objective was to study variations in the distribution and abundance of wood at a sample of sites
, in order to identify downstream trends and to understand how the controls on wood storage change along the length of the river.
This paper investigates the dynamics of the diverse vegetation in the south-west of Australia, and judges the degree of vegetation change identified against environmental change. The site chosen is close to one of Churchill's sites, West Lake Muir

Deforestation and the uses of wood in the Ecuadorian Andes
Andes ; Charcoal ; Deforestation ; Domestic use ; Ecuador ; Firewood ; Land use ; Living standard ; Mountain ; Rural economy ; Wood
Wood use is examined in four study areas in highland Ecuador in terms of its importance for the rural economy and its relation to deforestation. Concludes that the need for firewood does not explain deforestation; rather it responds to the demand
Impacts of river restoration on small-wood dynamics in a low-gradient headwater stream
Wood in world rivers. Special issue
Based on tracing dowels to simulate small wood in 3 study reaches before and after restoration, this study provides a detailed representation of the influence of restoration on small-wood transport and the relative importance of different trapping
Dynamics of wood transport in streams : a flume experiment
Carrying capacity ; Experimentation ; Fluvial dynamics ; Japan ; Model ; River bed ; River transport ; Stream ; Stream flow ; Transport ; Wood
The AA. examine some dynamics of wood transport in streams through a series of flume experiments, at the Publish Works Research Institute (PWRI), Tsukuba, Japan, and observe 3 distinct woodtransport regimes : uncongested, congested and semi
-congested. They present an analytical model that predicts flow conditions required to entrain individual pieces. These experiments examined wood movement as a function of flow conditions, channel morphology, and wood size and input rate. Results
of these experiments provide insight into how the depositional fabric of wood accumulations can be used to infer transport dynamics.
Characterizing the variability of wood in streams : simulation modelling compared with multiple-reach surveys
Wood in world rivers. Special issue
The AA. present 2 independent but complementary methods to develop frequency-volume distributions for wood in 200 m and 400 m reaches on tributaries of the Waihaha River, New Zealand. The first method uses a sliding window analysis of extensive wood
survey data, and the second method uses numerical models based on the Monte Carlo technique. The volume frequency distributions produced by the 2 methods are compared and their value in describing wood abundance in streams is discussed as well
as the implications for management of wood in streams.
