Forest and Community Structure of Tropical Sub-Montane Rain Forests on the Island of Dominica, Lesser Antilles
2016Caribbean Foresters: A Collaborative NetworkCaribbean for ForestNaturalist Dynamics and Regional ForestrySpecial InitiativesIssue No. 1 S.J. DeWalt, K. Ickes, and A. James 2016 CARIBBEAN NATURALIST Special Issue No. 1:116–137 Forest and Community Structure of Tropical Sub-Montane Rain Forests on the Island of Dominica, Lesser Antilles Saara J. DeWalt1,*, Kalan Ickes1, and Arlington James2 Abstract - To examine short- and long-term changes in hurricane-prone sub-montane rain forests on Dominica in the Lesser Antilles of the eastern Caribbean, we established 17 per- manent, 0.25-ha vegetation plots clustered in 3 regions of the island—northeast, northwest, and southwest. We counted all trees ≥10 cm diameter almost 30 years after Hurricane David caused substantial tree mortality, primarily in the southern half of the island. We identi- fied 1 vegetation association (Dacryodes–Sloanea) with 2 variants depending on whether Amanoa caribaea was co-dominant. We found that differences in forest structure and spe- cies diversity were explained more by region than forest type, with plots in the southwest generally having higher stem density, lower tree height, and greater species diversity than plots in the northeast or northwest. Our results suggest that differences in forest composi- tion in the sub-montane rain forests of Dominica are largely attributable to the presence or absence of the near-endemic canopy-tree species A. caribaea, and secondarily to the degree of hurricane-caused disturbance. Introduction The Caribbean is considered the third-most important global biodiversity hotspot (Mittermeier et al. 2004, Myers et al. 2000) due to the large number of endemic species, especially plants (Santiago-Valentin and Olmstead 2004), present there. -

Impact of Ethnobotanical Utilization on the Population Structure of Androstachys Johnsonii Prain
Bakali et al. Insights For Res 2017, 1(1):50-56 DOI: 10.36959/948/461 | Volume 1 | Issue 1 Insights of Forest Research Research Article Open Access Impact of Ethnobotanical Utilization on the Population Structure of Androstachys Johnsonii Prain. in the Vhembe Area of the Limpopo Province, South Africa Bakali M1, Ligavha-Mbelengwa MH1, Potgieter MJ2 and Tshisikhawe MP1* 1Department of Botany, University of Venda, South Africa 2Department of Biodiversity, University of Limpopo, Sovenga, South Africa Abstract Due to high levels of impoverishment, rural communities in southern African are highly dependent on their surroundings to sustain their livelihood. However, the rampant harvesting of Androstachys johnsonii Prain. In Vhembe area is a cause for concern although its conservation status is of Least Concern. Androstachys johnsonii is a tree species used for a variety of purposes in the Vhembe Area of South Africa to maintain households. Thus in order to obtain baseline data to propose ways of preserving the species, an investigation was launched to determine the extent of usage of A. johnsonii at Matshena village and document its population structure via stem size classes, crown health and plant height classes. Results indicate that this tree species is being used for a variety of purposes by inhabitants, with 65% of trees surveyed showing signs of harvesting. Due to its extremely durable hardwood this species is mostly used for fencing, roofing, pillar construction, and as firewood. Additional ethnobotanical uses include fodder for goats and cattle and medicinal purposes. Of the 353 A. john- sonii trees measured, the majority (27%) are in the 0-10 cm stem size class, and nearly 88% are lower than 5 m in height. -
Does Resource Availability Affect the Diet and Behavior of the Vulnerable Squirrel Monkey, Saimiri Vanzolinii?
Int J Primatol (2017) 38:572–587 DOI 10.1007/s10764-017-9968-7 Does Resource Availability Affect the Diet and Behavior of the Vulnerable Squirrel Monkey, Saimiri vanzolinii? Fernanda P. Paim1,2 & Colin A. Chapman3 & Helder L. de Queiroz1 & Adriano P. Paglia2 Received: 19 April 2016 /Accepted: 5 April 2017 /Published online: 1 June 2017 # Springer Science+Business Media New York 2017 Abstract Seasonal changes in food availability influence the behavior and diet of primates, and an understanding of dietary changes is important for the develop- ment of informed conservation plans. Saimiri vanzolinii is a small-bodied, om- nivorous squirrel monkey endemic to the floodplain forests in Central Amazonia. It has a restricted distribution of only ca. 870 km2 and is classified as Vulnerable. We examined seasonal variation in this species’ diet. We collected phenological (presence and absence of ripe fruits from 205 tree species) and dietary and behavioral data for unhabituated groups of S. vanzolinii on nine 2-km transects in the floodplain forests of Central Amazonia for 2 years, encompassing the high- water and low-water periods. Fruit availability was higher, and the monkeys traveled less and fed more during the high-water than the low-water period. There were no seasonal differences between the high-water and low-water periods in the time spent feeding on fruits, flowers, or arthropods. S. vanzolinii spent more time consuming fruit than arthropods in the high-water period, but this was not the case in the low-water period. These findings suggest that food selection changed between seasons, and S. -

Note that the list of genera is not exhaustive and the absence of a genus from a particular island group simply means that no reference was found to its occurrence in rainforest habitat in the references used (i.e. the genus may still be present in rainforest or may occur in that locality in other habitats). As the definition of rainforest can vary considerably among localities, for the purpose of this paper we considered rainforests to be terrestrial forest communities, composed largely of evergreen species, with a tree canopy that is closed for either the entire year or during the wet season.
