Trinidad and Tobago supports a rich biodiversity, largely thanks to its geographical position as a pair of Caribbean islands situated just 11 km off the coast of South America. However, as a small island developing state, it faces numerous pressures of human development on biodiversity and habitat integrity. Well-functioning natural history collections are key in documenting, monitoring and managing this biodiversity. The project team is keen to build on the progress established during a previous BID regional project, which allowed the University of the West Indies Zoology Museum (UWIZM) to publish more than 21,000 records to GBIF and train a range of stakeholders. This project will mobilize data from the remainder of the UWIZM collection (including an extensive and agriculturally important land arthropod collection containing 45,000 specimens) while forging partnerships with two other national institutions with significant collections. The combined collections of the UWIZM, the National Herbarium of Trinidad and Tobago (NH) and the National Museum and Art Gallery of Trinidad and Tobago (NMAG) hold more than 100,000 specimens. Each of the three collections will hold greater value if they are available in a consistent format from a single source. This project aims to fill data gaps by digitizing these collections. These datasets will be published on GBIF, making them easily accessible to policy-makers and other stakeholders through the Trinidad and Tobago Biodiversity Information System (TTBIS), a newly established archive of biodiversity data focused on protected areas. Training workshops will be designed to increase awareness and build national capacity, access and use of GBIF and TTBIS, with the ultimate aim expanding T&T data published to GBIF by trained stakeholders able to prepare and publish their own datasets.
|Title||Improving national biodiversity data accessibility in Trinidad and Tobago|
|Study Area Description||The country of Trinidad & Tobago including the smaller islands|
|Design Description||The aim of the present dataset is to provide information from the survey for terrestrial molluscs of Trinidad & Tobago conducted by Mike G. Rutherford from 2014-2017.|
The personnel involved in the project:
1. Fieldwork At each site searching by hand was undertaken for approximately one hour within a radius of approximately 5 to 20 metres from the coordinates depending on terrain and vegetation cover. Vegetation was examined up to a height of 2 metres, logs and stones were overturned and leaf litter was raked searching for live specimens and empty shells. At each site, several litres of leaf litter and soil were collected for further examination in a laboratory. At certain urban and agricultural sites, there was very little leaf litter, but soil samples were still taken. 2. Laboratory work These samples were then searched by the naked eye for live specimens and then spread out and left to dry in trays. The dried mixture was then put through a series of sieves (10 mm, 5 mm and 1 mm) with the resulting samples being examined under a stereomicroscope to find shells (magnification ranging from x4 to x40). The majority of specimens collected were dried empty shells which were stored in small plastic self-sealing bags with small shells being placed inside gelatine capsules for protection. There were also a few whole animals that were preserved in 70% ethanol. All specimens were labelled and catalogued in the UWIZM Past Perfect 5.0 database.
|Study Extent||Sampling was conducted at over 100 sites across Trinidad and Tobago including the largest of the smaller islands, Little Tobago, Monos, Huevos and Chacachacare. The sites selected for surveying were a subset of the 240 sites visited by the Rapid Botanic Survey of Trinidad & Tobago conducted from 2005-2008 by Oxford University, The University of the West Indies, the National Herbarium of Trinidad & Tobago and the Forestry Division and funded by the Darwin Initiative. This was done so that information on habitat and plant diversity could be easily compared with the molluscan diversity.|
|Quality Control||Identification was carried out by Mike G. Rutherford using suitable literature (see bibliography). Scientific names were validated using Molluscabase (accessed November 2021).|
