This amphi-Atlantic species occurs in sometimes great numbers at upper bathyal depths, rivaling polychaetes in numerical dominance. It appears to be an opportunist, with wide geographic and depth distribution, rapid development from lecithotrophic larva to settlement and maturity, and omnivory. A short illustrated morphological description using characters useful for identifying all prochaetodermatid species should prove useful to nontaxonomists whose business is the deep-sea benthic fauna

UN Forum series – how does progress look like in business and human rights?

This post was contributed by Martijn Scheltema, partner at Pels Rijcken & Droogleever Fortuijn and professor at Erasmus University Rotterdam. The 2015 United Nations Forum on Business and Human Rights will focus on tracking progress in (effective) implementation of the United Nations Guiding Principles on Business and Human Rights (UNGPs). This represents a significant opportunity to simultaneously improve the effectiveness of the UNGPs with respect to two important areas: human rights due diligence and access to remedy

The prolieration of contractual assurance in environmental and human rights due diligence supply chains

Contracts are regularly deployed to regulate corporate practices of suppliers in connection withenvironmental and human rights compliance as required by buyers in supply chains. Many buyers,mainly western brands, consider this to be an important means to undertake environmental andhuman rights due diligence as envisaged by the United Nations Guiding Principles on Business andHuman Rights (UNGPs) and the OECD Guidelines for Multinational Enterprises (OECD Guidelines).However, the current practices need improvement

The greening of Australia

Many urban Australians have little understanding of the problems of land degradation because it\u27s an extremely slow process that doesn \u27t directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss has been at the core of almost every aspect of land degradation in Australia , and that tree replacement will be essential if we are to redevelop the fertility of many of our degraded soils and maintain sustainable systems of agriculture (1), urban Australians do have a role in helping to revegetate our farm lands and in making \u27growing trees\u27 a community issue

Seasonal occurrence of balanomorph barnacle nauplius larvae in the region of the Antarctic Peninsula

The definitive version was published in Journal of Experimental Marine Biology and Ecology 392 (2010): 125-128, doi:10.1016/j.jembe.2010.04.016.Plankton samples taken along the west coast of the Antarctic Peninsula and in Bransfield Strait show widespread occurrence of Bathylasma corolliforme nauplius larvae during the austral spring, mid-October to the third week of December. During autumn, between the first week of May and early June there was a complete absence of balanomorph nauplii. This evidence shows periodicity in reproduction. There is a seemingly close correlation between the presence of these nauplii and the published data on phytoplankton biomass and seawater surface temperature.The research was supported by grants from the U.S. National Science Foundation Office of Polar Programs

Development and planktonic larvae of common benthic invertebrates of the Woods Hole, Massachusetts region : summary of existing data and bibliographic sources

The early life histories of more than one-half of the most common benthic invertebrates from the region of Woods Hole, Massachusetts have not been described. In many instances it has not even been determined whether or not the development of a species includes a planktonic stage. Larvae taken from the plankton often cannot be identified to species or even to genus because descriptions of their morphology do not exist; those descriptions that do exist are widely scattered in the biological literature. The extent of information that is available for the identification of larval forms is tabulated here for the most common species within the major benthic taxa in the Woods Hole region: gastropods, bivalve mollusks, decapod and stomatopod crustaceans, cirriped crustaceans, polychaete annelids, and echinoderms. (Not included are amphipods and isopods, and other peracarid crustacea, which do not have planktonic larval stages.)The production of this report was made possible under a grant from the Andrew W.
