I had confirmation my rights would be returned prior to the liquidation but Freight held on to them anyway. Throughout, thepublisher would tell me one thing and do another... I still don't have my rights and have no idea when I will. Nor do I expect to see a single penny of the four-figure sum owed to me. Shambolic doesn't come close." Larsen, F., Krog, C. & Eigaard, O.

Shepherd’s and Macpherson’s journeys to the Cairngorms could not be more different in tone or emphasis, but both writers find, whether focusing on life or death, a way of inhabiting the world. Wild Harbour , in a way unlike the vast majority of apocalyptic fictions, shows ways to live with disaster, even if that life is fleeting and contingent. Kastelein RA, de Haan D, Staal C.

Swimming patterns of wild harbour porpoises Phocoena phocoena show detection and avoidance of gillnets at very long ranges. Mar Ecol Prog Ser. 2012;453: 241–248. Although harbour porpoises preyed on fish around the bottom-gillnet, this does not indicate that the porpoises’ foraging activity around the net was depredation. Ammodytes sp. was not caught in the bottom-gillnet because their body height (<3 cm) is much smaller than the mesh size (7.5 cm). Therefore, it can be concluded that while harbour porpoises foraged around the net, their proximity to the net was not related to depredation. Since Ammodytes sp. is abundant and the targeted species of the bottom-gillnet including righteye flounders and sculpins also feed on Ammodytes sp. there, this location is a good fishing ground. It seems that their feeding place and the fishery ground are simply overlapping because of the distribution of Ammodytes sp. Increasing anthropogenic noise in the oceans is of growing concern due to the adverse effects noise may inflict on marine life 1. Most anthropogenic noise is produced incidentally by activities at sea, but in some cases noise is produced purposefully to deter marine mammals from specific locations or areas. The most common example is the noise produced by Acoustic Harassment Devices (AHD, source level > 185 dB re 1 µPa @ 1 m root mean squared, rms 2) and Acoustic Deterrent Devices (SL < 185 dB re 1 µPa rms 2, 3), also known as ‘seal scarers’, which have been developed to deter pinnipeds from fisheries and aquaculture to prevent depredation and damage to fishing gear 4. While the efficacy of the largely unregulated AHDs in terms of scaring seals away from lucrative sources of concentrated food is debated 3, mounting evidence suggest that AHD sounds may have substantial negative collateral effects on sympatric species such as harbour porpoises 5, 6, 7, 8.

Discussing the demise of Freight Books, Sinclair added: "We are sad to see Freight being wound up, and had hoped that a buyer would emerge over the past few months. That has not happened. It is sad to see a company disappear from the publishing landscape in Scotland and to see the effect it has had on all concerned. We put our efforts into helping Freight find a buyer and to help them with publishing issues as they emerged so it is a blow that they have not managed to do so, and that most of the authors will be without a home for their titles, in the short term at least.” Ruxton, G.
