There is controversy on the conditions under which cooperative learning methods can improve academic achievement. Group-specific motivational aspects might contribute to the effectiveness of cooperative learning among which classroom goal structures were focused on. More specifically, the study aimed at investigating the efficiency of cooperative writing technique through performance versus mas...

Reticulitermes santonensis is a subterranean termite that invades urban areas in France and elsewhere where it causes damage to human-built structures. We investigated the breeding system, colony and population genetic structure, and mode of dispersal of two French populations of R. santonensis . Termite workers were sampled from 43 and 31 collection points, respectively, from a natural populat...

In this paper, a Bayesian change-point model was used to examine the phenological changes in the predominant crop producing states of U.S over a 33-year period (1981–2013). Changes of phenological observation were categorized into a no-change model and two change models. The change point and intensity of shifts were subsequently estimated under the selected change model. The experiments were co...

The last decade a general shift has been realized in the water management sector in the Netherlands. The shift from a top-down (cooperative monopoloid) to a bottom-up institutional setting (cooperative multi-centric) was accompanied by various effects on the societal context. The benefits of the institutional shift do not only involve the most important actors (e.g. the Ministry of Transport an...

Perennial ryegrass is the most abundant grass species in temperate climates. An increased herbage intake of dairy cows by breeding new cultivars could have a large potential impact on agriculture. The effects of cultivars on sward structure, nutritive value, physical characteristics and disease resistance of perennial ryegrass are discussed. Cultivar differences were found in several studies fo...

One of the expected effects of the global warming is changing coastal habitats by accelerating the rate of sea level rise. Coastal habitats support large number of marine and wetland species including shorebirds (plovers, sandpipers and allies). In this study, we investigate how coastal habitats may be impacted by sea level rise in the Farasan Islands, Kingdom of Saudi Arabia. We use Kentish pl...

Spatiotemporal variation in seabird demographic parameters is often pronounced and may be an important source of information on the state of marine ecosystems. Black-legged kittiwakes Rissa tridactyla in Britain and Ireland show strong regional structure in breeding productivity, and both temporal and spatial variation are probably related to abundance of the principal prey of breeding kittiwak...

Water reclamation and reuse is being actively promoted in Australia. In Queensland, surface-flow constructed wetlands with a diversity of macrophyte types offer the greatest potential for effluent polishing. Constructed wetlands in subtropical climates in coastal regions and arid climates in inland western regions are conducive to high macrophyte growth rates and nutrient removal, in particular...

Stephen L. Peterson* Ecological succession and climate change are pushing tundra as well as Arctic and subarctic Robert F. Rockwell† lowland plant communities toward increased woody vegetation cover. However, areas Christopher R. Witte† and along the Hudson Bay Lowlands that are over-grazed by hyper-abundant lesser snow geese David N. Koons‡ are experiencing drastic losses of grass, sedge, and ...
