We studied density, size structure, and establishment sites of Coussapoa microcarpa in the Brazilian Atlantic rain forest. This species is a hemiepiphyte that begins its life in the tops of trees and survives the death of its host to become a free-standing tree. All individuals of C. microcarpa already rooted in the ground were recorded in a 3.43 ha (1.75 ha in lowland and 1.68 ha in submontane) sample of forest plots. Data on total height, root diameter at breast height, host height and diameter at breast height, as well as height, type and diameter of the establishment site were collected. Coussapoa microcarpa present a high density (36.5 ind. ha-1) and the population studied was composed mainly of young individuals. Young and adults differed in establishment sites. The diameter of establishment sites of young was narrower than the diameter of establishment sites of adults, which points out to a limiting factor (diameter of establishment site) regulating the establishment of C. microcarpa. © 2013 Cambridge University Press.

This new edition of Employment situation in Latin America and the Caribbean, a twice-yearly report prepared jointly by the Economic Commission for Latin America and the Caribbean (ECLAC) and the Office for the Southern Cone of Latin America of the International Labour Organization (ILO), discusses how weak job creation led to the third consecutive annual decline in the employment rate, which fell by 0.4 percentage points in 2015, indicating a reduction in the number of labour income earners per household. The ensuing drop in household income has played a large part in the increase estimated in the poverty rate for 2015. The second section of this report examines employment trends in rural areas of the countries of the region between 2005 and 2014, seeing to establish whether the improvements seen in the labour markets overall in that period also occurred in rural areas, and whether the gaps compared with urban areas decreased. The data presented in that section were generated from special processing of data from national household surveys.
