Aim Plant communities across the temperate zone are changing in response to successional processes and human-induced disturbances. Here, we assess how upland forest under- and overstorey community composition has changed along an edaphic gradient. Location Northern Wisconsin, USA. Methods Forest sites initially sampled in the 1950s were resampled for overstorey composition and diversity, basal area, and understorey composition and diversity. We used clustering methods to identify groups of stands based on overstorey composition, and we used similarity indices, ordination and diversity indices to evaluate changes in species abundance and overall community structure. Results Sites clustered into four overstorey groups along the edaphic gradient: 'hemlock' sites dominated by hemlock in 1950, 'mesic' sites dominated by northern hardwoods, 'dry' sites with a significant pine inclusion in the canopy and diverse 'dry-mesic' sites in the middle. Collectively, forests gained maple, ash and cherry while losing pines, birches and red oaks. The hemlock forest sites gained hardwoods, while the dry-mesic sites shifted towards a more mesic hardwood composition. Only the driest sites have remained relatively stable in species composition. Main conclusions These trends reflect both 'mesification' and homogenization among northern forests. Highly diverse mid-gradient and mesic hemlock-dominated stands are transitioning to maple dominance. Fire suppression may be favouring invasions of more mesic plants into historically drier sites, while high deer abundance likely limits hemlock regeneration. If current trends continue, maples will dominate the majority of northern forests, with significant losses of local native species richness and substantial shifts in understorey composition. © 2010 Blackwell Publishing Ltd.

Dactylogyrus robisoni n. sp. is described from the bluehead shiner, Pteronotropis hubbsi (Bailey and Robison), 1978, in Arkansas, U.S.A. Dactylogyrus robisoni is morphologically most similar to Dactylogyrus moorei Monaco and Mizelle, 1955, and Dactylogyrus ornatus Rogers, 1967, by possessing a long, slender, often sinuous copulatory accessory piece. The accessory piece of D. robisoni differs from those of the other 2 species by lacking a medial ramus and terminating in an elongate bulb. © 2011 The Helminthological Society of Washington. Source

This paper describes the processes we engaged into develop a measurement protocol used to assess the outcomes in a community based suicide and alcohol abuse prevention project with two Alaska Native communities. While the literature on community-based participatory research (CBPR) is substantial regarding the importance of collaborations, few studies have reported on this collaboration in the process of developing measures to assess CBPR projects. We first tell a story of the processes around the standard issues of doing cross-cultural work on measurement development related to areas of equivalence. A second story is provided that highlights how community differences within the same cultural group can affect both the process and content of culturally relevant measurement selection, adaptation, and development. © 2014 Society for Community Research and Action.

Microalgae CO 2 sequestering facilities might become an industrial reality if microalgae biomass could be produced at cost below $500.00 t -1. We develop a model for estimation of total production costs of microalgae as a function of known production-specific expenses, and incorporate into the model the effects of uncontrollable factors which affect known production-specific expenses. Random fluctuations were intentionally incorporated into the model, consequently into generated cost/technology scenarios, because each and every logically interconnected equipment/operation that is used in design/construction/operation/maintenance of a production process is inevitably subject to random cost/price fluctuations which can neither be eliminated nor a priori controlled. A total of 152 costs/technology scenarios were evaluated to find 44 scenarios in which predicted total production costs of microalgae (PTPCM) was in the range $200-500 t -1 ha -1 y -1. An additional 24 scenarios were found with PTCPM in the range of $102-200 t -1 ha -1 y -1. These findings suggest that microalgae CO 2 sequestering and the production of commercial compounds from microalgal biomass can be economically viable venture even today when microalgae production technology is still far from its optimum. © 2012 Elsevier Ltd.

Food Hydrocolloids | Year: 2015

In a waterless or near-waterless environment glycerol's hydroxyl groups react with xanthan's functional groups to make glycerol cross-linked xanthan (GCX) since not enough water is present to inhibit glycerol-xanthan reactions. The water, formed during cross-linking, in fact catalyzes the unwinding of xanthan's double-helix thus making functional groups of its side chains and of its backbone more accessible for cross-linking. Functional groups of xanthan's side chains and those in its backbone are cross-linked with glycerol monomers and oligomers. Glycerol monomers and its oligomers cross-link xanthan when glycerol to xanthan weight ratio is smaller than 27.6. Hardness increases with an increase of xanthan to glycerol ratio; GCX made with 50% wt xanthan is a hard solid material almost 40 times harder than GCX gel made with 5% wt xanthan. A gram of GCX absorbs more than 39 g of water. In a waterless or near-waterless environment glycerol cross-links xanthan and other bio-polymers. Materials made by glycerol cross-linking of bio-polymers can be used as hydrogels, absorbents, coatings, carriers in controlled delivery of chemicals, films, membranes and are of interest for those and other applications in agriculture, food, pharmaceutical and other industries. Using glycerol to cross-link bio-polymers and other compounds will also help decrease the pressure on the water resources and minimize pollution of the environment. © 2014 Elsevier Ltd. Source
