Book Description
This edited collection is a global history of workers’ organisations since 1919, the year when the International Labour Organisation (ILO), the Comintern and the International Federation of Trade Unions were formed. This historical moment represents a caesura in labour history as it epitomises the beginning of what the editors and the contributors in this book call the internationalisation of the labour question. The case studies in this centenary volume analyse the relationship between global workers’ organisations and the new ideological confrontation between liberal capitalism, socialism and communism since the Bolshevik Revolution in Russia. Workers’ organisations, trade unions in particular, grew in importance and managed to organise internationally, forming alliances cemented by ideology and sustained by international institutional bodies or centrals. In the nascent capitalist versus communist struggle, trade unions thrived. Is it mere coincidence that today’s decline of unionism coincides with the end of ideological antagonism? This book emphasises important global labour issues such as gender as well as international workers’ histories from Latin America, Asia and Africa.

Book Description
This illustrated manual is a guide to the distribution and identification of the 6 genera and 28 species of benthic and planktonic Chaetognatha known to occur in the Caribbean Sea, the Gulf of Mexico, the Florida Straits, and the southwestern North Atlantic Ocean. As background, previous studies of chaetognaths in these areas are reviewed, gross morphology of the different forms is described, and instructions on methods of preserving and handling specimens preparatory to identification are provided. The key to genera and species is preceeded by a discussion of chaetognath taxonomy. A description of each species, consisting of an abbreviated synonymy, a summary of taxonomically important morphological features, and horizontal and vertical distribution follows the key. The occurrence of species in relation to water masses in the Caribbean and adjacent areas is noted.

Book Description
Apart from being commercially and socially significant, anchovies and sardines populations occupy crucial positions in the oceans' ecosystems. Low in the food chain, clupeoids tend towards abundance, as if their purpose in life was to be eaten and fuel the upper levels of marine trophic chains. The present book covers a broad spectrum of topics on

Book Description
This book compiles the main findings of the multidisciplinary long-term research program developed in the continental margin of one of the more productive and unknown areas of the world oceans, Northwest Africa. The more than 25,000 preserved fishes and benthic invertebrates and quantitative data collected in 342 trawling stations, the 267 oceanographic profiles, the 211 sediment samples and the 28,122 km2 prospected by multi˗beam echo sounding allowed to obtain an overview of the amazing biodiversity of the demersal and benthic fauna inhabiting soft- and hard-bottom habitats, as well as the fascinating geomorphology and oceanography, hidden in the Mauritanian slope.
