We used a multi-method approach to analyze the spatial patterns of shrubs and cover types (plant species, litter or bare soil) in grassland-shrubland ecotones. This approach allows us to assess how fine-scale spatial heterogeneity of cover types affects the patterns of Cytisus balansae shrub encroachment into mesic mountain grasslands (Catalan Pyrenees, Spain). Spatial patterns and the spatial ...

In coastal marshes on James Bay and southern Hudson Bay, Canada, the grass Festuca rubra L. is heavily used for forage by both Snow (Chen caerulescens caerulescens (Linnaeus)) and Canada Geese (Branta canadensis (Linnaeus)). On Akimiski Island, James Bay, this grass occurs in a mosaic of short, heavily grazed patches and tall, lightly grazed patches. We investigated whether short plants are pri...

In this paper, we provide the first observations of maternal care for the harvestman family Cranaidae. Adult females of two species, Santinezia serratobialis Roewer 1932, which belongs to the group curvipes, and Santinezia sp., which is probably a new species of the group gigantea, were found in association with egg clutches. Since the microhabitats used for oviposition by these species are ver...

Poria carnegieae was described from Arizona growing on the woody ribs of saguaro cactus, Carnegiea gigantea, and transferred to Ceriporiopsis due morphological evidence. Posterior phylogenetic studies showed a relationship with Bjerkandera. New sequence data morphologic evidence are presented support transfer

One important area for which little experimental evidence is available is the snowgrass country. There is a strong body of opinion that in the snowgrass the combined effects of fire and grazing have been responsible for deterioration in vegetative cover and stability. It seems likely that changes in the boundari~s between the snowgrass and fescue communiti~s have been due to, or aggravated by, ...

in the last. Bermuda hay made up a large part of the total dry matter intake during the last 47 days of the trial. Daily intake of protein should have been very adequate in the early part of the test, but would have declined to marginal levels during the last 56 days due to the weather related failure to grow green forage. The overall response to providing 200 mg. of monensin to cattle grazing ...

Pseudomonas putida GM4FR is an endophytic bacterium isolated from aerial plant tissues of Festuca rubra L. Functional annotation of the draft genome (7.1 Mb) revealed 6,272 predicted protein-encoding genes. The genome provides insights into the biocontrol and plant growth-promoting potential of P. putida GM4FR.
