Abstract Tuck, G. N., Phillips, R. A., Small, C., Thomson, B., Klaer, N. L., Taylor, F., Wanless, M., and Arrizabalaga, H. 2011. An assessment of seabird–fishery interactions in the Atlantic Ocean. – ICES Journal Marine Science, 68: 1628–1637. Currently, 17 22 albatross species are listed as Vulnerable, Endangered, or Critically endangered by International Union for Conservation Nature (IUCN). Incidental mortality fisheries is far most widespread cause population declines observed these...
Abstract Adult female survival as a potential proximate factor responsible for observed changes in southern elephant seal Mirounga leonina populations was investigated. We compared the rate estimates from mark–recapture data seals Marion Island population (using program MARK) two periods (pre‐ and post‐decline) during past 15 years with another Argentina, which had increased steadily same period. Survival of prime‐age adult females significantly by 6.2% latter part decline at Island, colony...
Abstract The subantarctic Prince Edward Islands (Marion and Edward) support the largest breeding population of Vulnerable wandering albatross Diomedea exulans. number birds at Marion Island has fluctuated over past three decades apparently as a result both real changes in size proportion that attempts to breed given year. Changes several demographic parameters appear be influenced by environmental anthropogenic effects are described. From 1994–2001, first-time breeders was positively...
Seabird bycatch in industrial fisheries has been the focus of research and conservation concern since late 980s (e.g. Weimerskirch & Jouventin 987, Bartle 99 , Brothers ). Recent explored impacts seabird longline (Tuck et al. 200 Lewison Crowder 2003) trawl (Weimerskirch 2000, Sullivan Reid 2003). Understanding impact on species involves both quantifying number individuals affected (including lethal sub-lethal effects) determining effect, if any, that could have at population or community...
The means by which populations are regulated form a central theme in conservation biology, and much debate has revolved around density dependence as mechanism driving population change. Marion Island (46°54‘S, 37°45‘E) is host to relatively small breeding of southern elephant seals, like its counterparts the Indian Pacific Oceans, have declined precipitously over past few decades. An intensive mark–recapture study, commenced 1983, yielded long time-series resight data on this population. We...
Italian author Elena Ferrante has been described as the "master of unsayable". By examining two her novels, namely My Brilliant Friend (New York: Europa Editions, 2016) and The Lying Life Adults (London: 2020), I attempt to explore realist methodology depiction female friendship a means creating sense truth-telling. Both novels focus on friendships set in Naples, although is post-World War II era 1990s. examine Ferrante's use content, characterisation, theme friendship, writerly style....

Plates 1-15 of the Ishihara tests for color blindness were administered to 5,580 boys and 5,405 girls in primary secondary schools Lagos. The difference between males females frequency total was not significant. among children 0.19%. However, frequencies red-green blindness, which 3.60% 0.81% females, respectively, significantly different. Deutans occurred at a higher than protans both male female blind individuals, but differences also In addition, there no significant sexes occurrence...
