Modelling reproductive effort in sub-and maritime Antarctic mosses

first_imgA comparison is made of the reproductive effort (RE), considered as the investment in sporophyte relative to gametophyte biomass, of eight species of moss occurring at sub-and maritime Antarctic sites. Six of the species showed smaller sporophytes and game-tophytes at the climatically more extreme maritime Antaretic sites and one species showed no size difference between regions. The remaining species, although showing no regional difference, showed some evidence of a reverse pattern, with higher altitude samples having greater biomass than lower altitude samples. Spore counts indicated a measure of compensation in maritime Antarctic samples, with no significant decrease in spore output in several species despite smaller sporophyte biomass. The relationship between sporophyte (S) and gametophyte (G) biomass within samples was described by an allometric curve (S=aGb) which gave a better fit than a straight line for six species. This form of model allows comparisons of patterns of RE to be made between samples with non-or partially overlapping size distributions, even when the relationship involves size-dependence. An allometric curve was not appropriate for describing samples of one species (Andreaea regularis), and insufficient data were available to identify any relationship in Polytrichum alpinum. The exponent (b) differed between species, but there were no statistically significant differences between exponents from samples of the same species. Samples of two species could further be described by the same coefficient (a), indicating that they lie on the same curve. However, samples of three species from sub-Antarctic South Georgia gave significantly higher coefficients, indicating increased RE relative to maritime Antarctic populations.last_img read more

Press release: International summit to crack down on sexual predators in the aid sector

first_img Email [email protected] Announcements to include new Interpol pilot in Asia and Africa to stop predators using the aid sector as a cover to harm vulnerable people This is a pivotal moment. The entire international aid community is in one place, as it looks to change for the better the way the aid sector works. Our message to sexual predators using the sector as a cover for their crimes is ‘Your time is up’. This summit will consolidate the work we have done to date to tackle exploitation and abuse and we will be announcing concrete practical actions and new law enforcement tools, which will bring about significant changes. We are demanding tough commitments from donors, NGOs and other aid organisations. We are not complacent. We realise there is much work still to do, but this a moment to say: ‘No more’. We have to give the people that we are here to help the protection that they need. General media queries (24 hours) At the summit Ms Mordaunt will announce that DFID and Interpol are launching a pilot to help stop sexual predators from being able to move between aid organisations without being caught.In addition, the UK will support NGOs, particularly small organisations, to strengthen their systems and processes via a new platform, which will include access to specialist investigators.The UK is supporting NGOs to test a new passport for aid workers to prove an individual’s identity, provide background information and vetting status. This will make it easier for employers to gather up to date information on applicants.DFID will also support the UN Victims’ Rights Advocate to establish a Victims Statement of Rights. This will provide clear, guidance to organisations on how to put victims and survivors first and improve support.Ms Mordaunt will announce the new Interpol project, named Operation Soteria after the Greek goddess of safety, will include deploying teams of specialists to two regional hubs in Africa and Asia to strengthen criminal record checks and information sharing between all 192 members, including high risk countries, and help ensure a more robust law enforcement response against individuals.Interpol Secretary General Jürgen Stock said: The pilot will be led by Interpol, ACRO Criminal Records Office and Save the Children who are coordinating NGO’s participating in the project. This is a five-year project with an initial one-year phase focused on testing the online platform, which will build on existing Interpol systems. This is a £10 million project, in which the UK has taken a leading role. It will commit £2 million, subject to approvals for the inception phase.

This is all the more important when sexual predators attempt to exploit the very people – be it men, women or children – they are supposed to be safeguarding from harm. International donors, who collectively provide over 90 per cent of global official aid, the UN, international financial institutions and a range of UK-based organisations (NGOs, contractors, research organisations and CDC, the UK’s development finance institution) will make concrete commitments at the summit.The summit follows an event in March co-hosted by DFID and the Charity Commission where Ms Mordaunt challenged UK-based international development charities, regulatory bodies and independent experts to drive up standards to ensure the aid sector protects the people it serves. As part of this, DFID put in place new, enhanced safeguarding standards for the organisations the department works with. Today’s event will focus on the international community.Notes to editors: Safeguarding Summit 2018: Are you listening?Free-to-use photographs from this event are available to download hereInternational Development Secretary Penny Mordaunt will call on the global aid community to take action today, saying “enough is enough”, as the Department for International Development (DFID) and the international aid sector clamps down on sexual predators abusing the most vulnerable people around the world.Speaking ahead of the International Safeguarding Summit in London today (Thursday 18 October) Ms Mordaunt said: Summit’s theme to be “Putting People First” – with the focus on preventing abuse and improving support for victims and survivors If you have an urgent media query, please email the DFID Media Team on [email protected] in the first instance and we will respond as soon as possible.last_img read more

Swans moves for Emnes

first_img Press Association Swansea are set to sign Marvin Emnes on loan from Middlesbrough, Press Association Sport understands. The 25-year-old Dutchman had a one-month spell with the Swans three seasons ago, making himself a fans’ favourite by scoring the winner in a south Wales derby win over Cardiff. Swansea have tried to bring the striker back to the Liberty Stadium on several occasions since, and they look to have succeeded on his occasion with moves for Tom Ince, Anthony Pilkington and Nacer Chadli having failed to come to fruition. center_img The deal will see Emnes, who has scored just once for Boro this term, make the move to south Wales until the end of the season. last_img read more
