TL;DR: The global difference in species richness between unmanaged and managed forests increased with time since abandonment and indicated a gradual recovery of biodiversity, which supports the need for a coordinated European research network to study and monitor the biodiversity of different taxa in managed and unmanaged forests.
Abstract: Past and present pressures on forest resources have led to a drastic decrease in the surface
area of unmanaged forests in Europe. Changes in forest structure, composition, and dynamics inevitably
lead to changes in the biodiversity of forest-dwelling species. The possible biodiversity gains and losses due to
forest management (i.e., anthropogenic pressures related to direct forest resource use), however, have never
been assessed at a pan-European scale. We used meta-analysis to review 49 published papers containing 120
individual comparisons of species richness between unmanaged and managed forests throughout Europe. We
explored the response of different taxonomic groups and the variability of their response with respect to time
since abandonment and intensity of forest management. Species richness was slightly higher in unmanaged
than in managed forests. Species dependent on forest cover continuity, deadwood, and large trees (bryophytes, lichens, fungi, saproxylic beetles) and carabids were negatively affected by forest management. In contrast,
vascular plant species were favored. The response for birds was heterogeneous and probably depended more
on factors such as landscape patterns. The global difference in species richness between unmanaged and
managed forests increased with time since abandonment and indicated a gradual recovery of biodiversity.
Clearcut forests in which the composition of tree species changed had the strongest effect on species richness,
but the effects of different types of management on taxa could not be assessed in a robust way because
of low numbers of replications in the management-intensity classes. Our results show that some taxa are
more affected by forestry than others, but there is a need for research into poorly studied species groups in
Europe and in particular locations. Our meta-analysis supports the need for a coordinated European research
network to study and monitor the biodiversity of different taxa in managed and unmanaged forests.

TL;DR: It is shown that the effect of ethylene on root growth is largely mediated by the regulation of the auxin biosynthesis and transport-dependent local auxin distribution, and ethylene achieves a local activation of the Auxin signaling pathway and regulates root growth by both stimulating the aux in biosynthetic process and by modulating the auxIn transport machinery.
Abstract: In plants, each developmental process integrates a network of signaling events that are regulated by different phytohormones, and interactions among hormonal pathways are essential to modulate their effect. Continuous growth of roots results from the postembryonic activity of cells within the root meristem that is controlled by the coordinated action of several phytohormones, including auxin and ethylene. Although their interaction has been studied intensively, the molecular and cellular mechanisms underlying this interplay are unknown. We show that the effect of ethylene on root growth is largely mediated by the regulation of the auxin biosynthesis and transport-dependent local auxin distribution. Ethylene stimulates auxin biosynthesis and basipetal auxin transport toward the elongation zone, where it activates a local auxin response leading to inhibition of cell elongation. Consistently, in mutants affected in auxin perception or basipetal auxin transport, ethylene cannot activate the auxin response nor regulate the root growth. In addition, ethylene modulates the transcription of several components of the auxin transport machinery. Thus, ethylene achieves a local activation of the auxin signaling pathway and regulates root growth by both stimulating the auxin biosynthesis and by modulating the auxin transport machinery.

TL;DR: The European wild boar was crossed with the domesticated Large White pig to genetically dissect phenotypic differences between these populations for growth and fat deposition, and the genetic mapping of a major locus for fat deposition in the pig could have implications for understanding human obesity.
Abstract: The European wild boar was crossed with the domesticated Large White pig to genetically dissect phenotypic differences between these populations for growth and fat deposition. The most important effects were clustered on chromosome 4, with a single region accounting for a large part of the breed difference in growth rate, fatness, and length of the small intestine. The study is an advance in genome analyses and documents the usefulness of crosses between divergent outbred populations for the detection and characterization of quantitative trait loci. The genetic mapping of a major locus for fat deposition in the pig could have implications for understanding human obesity.

TL;DR: In this article, the authors define agroecology as the ecology of food systems and provide a framework that will guide research, education, and action in the multiple and interacting facets of an increasingly complex global agriculture and food system.
Abstract: We present a compelling rationale for defining agroecology as the ecology of food systems. Our purpose is to provide a framework that will guide research, education, and action in the multiple and interacting facets of an increasingly complex global agriculture and food system. To accomplish such goals, it is essential to build bridges and connections among and beyond our disciplines in production agriculture, as well as beyond the farm gate into the rural landscape and community. Fields of sociology, anthropology, environmental sciences, ethics, and economics are crucial to the mix. They provide additional vantage points from which we can view the food system anew, as well as insights on how to establish valuation criteria beyond neoclassical economics. Examples from Mexico, California, and the Nordic Region are used to illustrate the successful implementation of this educational strategy in universities. Design of individual farms using principles of ecology is expanded to the levels of landsca...

TL;DR: The availability of purified fucans and fucan fractions with simple, but varied structures, in conjunction with the development of new enzymatic tools, demonstrate that the biological properties of sulfation are not only a simple function of their charge density but also are determined by detailed structural features.
Abstract: Sulfated fucans, frequently referred to simply as fucans, constitute a class of polysaccharides first isolated in 1913. For many years fucans were regarded only as a potential source of l-fucose, although their anticoagulant activity was known. Even as the potent effects of fucans on physiological systems have become better characterized, structural studies have lagged behind. Recently the search for new drugs has raised increased interest in sulfated fucans. In the past few years, several structures of algal and invertebrate fucans have been solved, and many aspects of their biological activity have been elucidated. From this work emerges a more interesting picture of this class of polysaccharides than was previously suspected. The availability of purified fucans and fucan fractions with simple, but varied structures, in conjunction with the development of new enzymatic tools, demonstrate that the biological properties of sulfated fucans are not only a simple function of their charge density but also are determined by detailed structural features.
