“…Widespread abandonment of agricultural land due to socioeconomic changes has allowed forest recovery (Thomlinson et al, 1996;Ló pez et al, 2001;Helmer, 2004;Kennaway and Helmer, 2007;Helmer et al, 2008) to such an extent that forest cover had reached 32% by 1980 (Birdsey and Weaver, 1982) and 57% by 2003 . The forests of the U.S. Virgin Islands also experienced a colonial period of deforestation for export agriculture followed by forest recovery (Weaver, 2006a,b).…”

“…Deforestation for industrial-scale agriculture clears larger areas faster than the forest clearing for small-scale or subsistence agriculture that dominated in earlier decades. In some countries, however, secondary tropical forests are recovering on much of the land previously cleared for agriculture (Kauppi et al, 2006), including several countries in the Caribbean, which is the location of this study (Helmer et al, 2008). These secondary forests provide our best opportunities to answer questions about the relative influences of land-use history vs. climate and other biophysical influences on secondary forest species composition.…”

“…However, much of this forest loss has occurred in the past, and on some islands, the proportion of forest cover has increased in recent years as people abandon agriculture and migrate to towns and cities [34][35][36][37]. Although forest cover has increased with abandonment of agriculture on these islands, development and urbanization have increased mostly in the lowlands where habitats continue to face increased development pressures [37,38]. On abandoned lands, some of the regenerating second-growth forests have a mix of native and alien tree species and given this mixture, have been designated as novel forests [39,40].…”

Here, we summarize results of migrant bird research in the Caribbean as part of a 75th Anniversary Symposium on research of the United States Department of Agriculture Forest Service, International Institute of Tropical Forestry (IITF). The fate of migratory birds has been a concern stimulating research over the past 40 years in response to population declines documented in long-term studies including those of the IITF and collaborators in Puerto Rico's Guánica dry forest. Various studies indicate that in addition to forest loss or fragmentation, some migrant declines may be due to rainfall variation, the consequences of which may carry over from one stage of a migrant's annual cycle to another. For example, the Guánica studies indicate that rainfall extremes on either the temperate breeding or tropical wintering grounds affect migrant abundance and survival differently depending on the species. In contrast, IITF's collaborative studies of the migrant Kirtland's Warbler (Setophaga kirtlandii) in the Bahamas found that late winter droughts affect its annual survival and breeding success in Michigan. We review these IITF migrant studies and relate them to other studies, which have improved our understanding of migrant ecology of relevance to conservation. Particularly important is the advent of the full annual cycle (FAC) approach. The FAC will facilitate future identification and mitigation of limiting factors contributing to migrant population declines, which for some species, may be exacerbated by global climate change.

“…Coastal areas fi gure prominently in this economic model. Management strategies have been enacted to both support local economic viability and resource preservation with the context of sustainable models (Thomas 2000 ; Helmar et al 2008 ). The caves of Grenada and adjacent insular environments also feature substantial biodiversity associated with coastal and interior landscapes (Pederson et al 2013 ).…”

Coastal karst is a dominant landform within the Caribbean that has played a signifi cant role in shaping human migration and settlement patterns, modern economic development in the region and its evolving biodiversity. Recent exploration of coastal karst, associated models of littoral cave development and comparative coastal resource management strategies are examined in three distinct island settings in the Caribbean: The Republic of Haiti, Grenada and Isla de Mona (Puerto Rico). These regional island examples display distinct and complex coastal karst morphologies ranging from intensely karstic carbonate platforms to complex non-carbonate island cores overlain by extensive and thickly-bedded coastal and interior carbonate cover or predominantly volcanic landscapes with limited fringing carbonates. Previously unreported fi eld research in these selected island settings support an emerging view of the complex karst development in the region and indicate that signifi cant karst areas remain to be explored while illustrating the associated landform vulnerabilities, anthropogenic effects and range of coastal resource management and preservation initiatives applied to date.
