There is a lack of information regarding the ecology and behaviour of red foxes that can be used to elaborate effective management programs for this species on Prince Edward Island (Canada). The main goal of this study was to provide baseline information on habitat selection and home range size of r...

This is the first in a series of papers documenting the marine algae from some islands of the Sulu Sea. A historical sketch of the scientific explorations in the Sulu Sea is presented with emphasis on marine algal researches. The present report lists 19 additional species of marine algae for the Tub...

Mature nymphs of Pteronarcys biloba collected from Catamaran Brook, New Brunswick, between October 1994 and October 1995, were hosts to high numbers of parasitic chironomid larvae [Nanocladius (Plecopteracoluthus) undescribed sp., nr, branchicolus]. Nanocladius (P.) sp. has a univoltine life cycle i...

Oxidative stress in the vasculature and kidneys contributes to hypertension, a major risk factor for cardiovascular disease. Blueberries (BB) are rich in antioxidants, and so we hypothesized that feeding diets enriched with BB would slow the development of hypertension in spontaneously hypertensive ...

Background and Aims: By using the technique of replicas of a developing apex it is possible to obtain a direct measure of phyllotactic parameters (plastochrone and platochronic ratio) involved in the initiation of two successive primordia at the level of the SAM. The goal of this study is to compare...

The spadix of M. arborescens has a cylindrical or ellipsoid form at maturity and contains unisexual flowers without a perianth. The pistillate and staminate flowers are located in the basal and apical portions, respectively, of the inflorescence. In the upper portion of the female zone, there is a r...

We studied the infestation of the burrowing polychaete Polydora rickettsi on the shells of Crepidula fecunda in relation to the degree of intertidal exposure in Yaldad Bay (Chile). 175 specimens of C.fecunda were collected from five stations located at tidal levels experiencing air exposures of 0, 2...

Specimens of Thorea violacea Bory de St. Vincent (Rhodophyta, Batrachospermales) were collected from Matutinao River, southwestern Cebu, Philippines. The collection represents a new Philippine record and is the fourth genus of freshwater Rhodophyta recorded for the Philippine algal flora. Morphologi...

It is well established that the developing brain is a highly dynamic environment that is susceptible to toxicity produced by a number of pharmacological, chemical and environmental insults. We report herein on permanent behavioural and morphological changes produced by exposing newborn rats to very ...

Individuals (n=30) of the common prosobranch mollusk Cronia margariticola from three populations around Mactan Island were examined for the occurrence of imposex. These populations were obtained from habitats exhibiting three presumed different levels of pollution, namely a ship repair and oil depot...

1. Life history patterns and production of eight shredder-detritivore species were studied in relation to the detritus dynamics of a small acidic stream in England. Mean annual detritus inputs (direct and lateral sources combined) were approximately 400 g m(-2) year(-1) and showed significant season...

Temperature data loggers were deployed in several northern Alberta lakes, and the data collected were used to compute the cumulative number of days for which water temperature exceeded the 13.5 degrees C minimum temperature required for yellow perch (Perca flavescens) growth. Tow-net and seine sampl...
