As part of a long-term ecological study of the cryptic comunity of Jamaican coral reefs carried out by Jeremy B.C. Jackson and associates during the 1970s and early 1980s, collections were made of reef bryozoans found at 14 sites around the island. Space occupied by bryozoans on undercoral surfaces is dominated by relatively few species. However, during scanning electrone microscopy study and monograph preparation a diverse assortment of relatively rare species was discovered. Of the 132 species found, 56%, 74 species (70 cheilostomes and 4 cyclostomes) are new, as are one family (Inversiscaphidae) and 5 genera (Planospinella, Caribaria, Spirocoleopora, Gemellitheca, and Palliocella).

The assessment of long-term effects of oil pollution is ultimately a matter of field responses and ecological interpretation. Chronic conditions present much greater interpretative problems than the aftermath of a severe spill because the detection of subtle effects has to be made against the usually unknown scales of natural changes taking place. Examples from various coastal benthic communities illustrate types of biological interactions, different types and degrees of biological stability and the sometimes unpredictable timescales involved. Special attention is drawn to the significance of natural fluctuations in recruitment and to the geographical scales on which these may occur. Have such matters been taken into account in the past? For the future the extreme difficulty that may be involved in detecting subtle deterioration necessitates both a considerable increase in ecological awareness and the directing of work on sublethal effects to those species most am enable to ecological study.

In 1949 the Australian National Antarctic Research Expeditions (ANARE) began a long-term ecological study of the Southern Elephant Seal (Mirounga leonina) at HeardIsland. The biologists devised a method of branding seals for individual recognition (Chittleborough and Ealey, 1953) which has been modified only in detail since then (Carrick and Ingham, 1962a). At Heard Island, pups were branded every year until 1953, but the study here came to an end with the closing of the ANARE station in 1955. At Macquarie Island, pups have been branded every year from 1951 to 1965, giving a sample of individuals of known age and known history.

Changes in scientific views, approaches, and the public's environmental concerns have broadened the foci of silvicultural research from individuals in stands to these plus other interacting components at broader temporal and spatial scales. Present studies have benefited from increasing interdisciplinary ecological study; however, even the most interdisciplinary research and management could be improved by (1) moving beyond public comment to incorporating the public's environmental concerns into experimental and management designs; (2) being conducted at scales (time and space) that are appropriate to ecosystem components of greatest concern; (3) encouraging researchers and managers to test their knowledge using landscape-level forest vegetation management and checking predictions using sufficient monitoring; and (4) recognizing that within-study integration will require identifying study-appropriate integrative currencies.

Structured Questionnaire

This study conducted around three provinces of Gabon (Estuaire, Ngounié, and Nyanga) aims at exploring gender dynamics, economics, and vulnerability perceptions in the bush mango value chain by analyzing male-female roles and relationships. Interviews were randomly conducted with 174 actors as follows: 132 (Estuaire), 12 (Ngounié), and 30 (Nyanga) provinces using a semi-structured questionnaire and field observations. Women headed households dominate harvesting (21.8%), processing/trading (10.3%) and trading stages (55.2%) compared to men harvesting (7.5%), processing/trading (0.6%) and trading (4.6%). Women tend to generate relatively higher annual gross average income (1.4 million FCFA per annum), which is 1.7 times higher than that of men. Poor management of resources, the lack of harvesting norms, logging-driven deforestation, and slash-and-burn agriculture are among the perceived factors threatening the value chain. Targeted policy and actions on a gender perspective are suggested to reduce income inequality between men and women along the value chain. A long-term ecological study to monitor changes over forest resources use is crucial before carrying out any mitigating measures based on cultivation and domestication in the study areas.
