The Jamaican-grown West Indian raspberry (Rubus rosifolius) falls into this category. The first step to taking this wild-growing plant into agricultural production is morphological identification. Although there are no botanical reports of multiple varieties of this species in Jamaica, two morphotypes were found, which were named ‘Red' and ‘Wine Red’ based on fruit colour. Morphological methods were used to characterise these plants growing at Holywell (located over 900 m above sea level), in the Blue Mountain region of Jamaica. Morphological analyses revealed that growth form, leaf, flower, and fruit characteristics of the morphotypes were statistically distinctive between the two morphotypes for 48 of the 59 measured parameters. Several descriptors allowed the morphotypes to be distinguished before their fruits became visible. These findings support the hypothesis that there is a standard morphotype having a scrambling morphology, smaller leaves, and darker red, oblong, solitary fruits (Wine Red, WR), and a distinct morphotype with more upright stems, larger leaves, and lighter red, spherical, bunched fruits (Red, R). This information can now be used to facilitate molecular analyses and ramp-up clonal production of these morphotypes to determine the agricultural factors that are linked to yield and nutritionally relevant traits.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"51 1","pages":"1 - 13"},"PeriodicalIF":0.4,"publicationDate":"2021-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47640160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the current status of the hutia population in southeastern Cuba through (1) estimation of population density via walking and driving surveys, and (2) hutia spatial ecology via Global Positioning System (GPS) collars. Driving surveys indicated lower mean hutia density (x̄ = 0.14 hutias/ ha) than walking transects (x̄ = 1.13 hutias/ha). Three of 13 GPS-collared hutias provided sufficient data for range analyses as 10 hutias severely damaged their GPS units. Ranges were relatively small (50% Core Area, x̄ = 0.50 ha; 95% Range, x̄ = 2.63 ha) and individuals tended to stay very close to tree cover, only emerging at night to forage. We recommend continued monitoring of hutia populations due to their influence on rare vegetative communities and importance as a significant food source for the Cuban boa (Chilabothrus angulifer).","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"50 1","pages":"258 - 264"},"PeriodicalIF":0.4,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41815965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sample of 104 residents and 103 visitors on St. Kitts was verbally interviewed about their knowledge, attitudes, and support for mongoose control. Respondents generally valued mongooses, but there was a high level of support for controlling them, preferably through non-lethal means, if these animals were perceived to present disease, or threats to agriculture or conservation efforts. Differences in responses were seen between residents and visitors, and by gender and level of education, showing that attitudes towards mongoose control were not homogeneous. The low perceived risks, perceived benefits, and positive attitudes towards mongooses found in this study seem to not favor lethal control measures, but may allow for non-lethal control if the risks can be made apparent to residents and visitors. Helping people formulate accurate perceptions of the risks and benefits is an important part of developing support for a management action. This invasive species management situation might benefit from a focus on protecting sea turtles to make it a specific and identifiable risk management action rather than focusing on generic mongoose control goals.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"50 1","pages":"250 - 257"},"PeriodicalIF":0.4,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47468775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These ponds were classified as small, mixed, or large based on cluster analysis, which created these groups based on size and physicochemical parameters. Regression of mass on length was completed for most benthic macroinvertebrate taxa, and consequently 170 length-mass equations were developed for use in mass determination locally and regionally. The sample area was taxonomically rich, consisting of 78 species, 43 families, and 14 orders, with class Insecta having the largest number of taxa. Biomass was constant over time, which implied that food availability was not limited for invertebrates in the sample area. The results indicated that biomass in the sample area was dominated by Aeshnidae and Belostomatidae, which had significantly higher values than most other taxa. Culicidae, and the families of Diptera in general, were not well represented in the biomass within the sample area. Total production for the sample area was estimated to be 398.87 g m-2yr-1, with the highest values for production being obtained for Anisoptera, Podocopoida, and Ephemeroptera; while the P/B ratio of Podocopoida was significantly higher than most taxa. When the results were assessed based on pond groups, families of the class Insecta, particularly Aeshnidae and Belostomatidae, had significantly high biomass in large and mixed ponds, while Physidae dominated the biomass of small ponds. The productivity results almost mirrored what was observed for biomass; however, Cypridoidea (ostracods) showed high productivity in the mixed group although its biomass contribution was <3%. These findings are the first to examine biomass, production and P/B ratios in a lentic habitat in Jamaica, compute length-mass equations, and form an important record against which other studies within the island and throughout the Caribbean can be compared to.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"50 1","pages":"275 - 300"},"PeriodicalIF":0.4,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48766006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that germination will be directly and negatively affected by HCM infestation severity. After measuring germination and seedling survival for 160 days, we observed that seeds from fruits growing on tumors had the lowest germination rate compared to the other categories, as hypothesized. In addition, lightly infested plants germinated at a lesser rate compared to healthy plants, while seeds from severely infested plants germinated at a greater rate, contrasting with our hypothesis.

Oral rabies vaccination (ORV) has been suggested to prevent the spread of rabies in mongooses, but there are limited data on ORV bait survival in maritime/tropical climates. We compared disappearance rates of an egg-flavored bait block vs. a control (canned tuna) and for bait blocks, we assessed if season, habitat, and day/night would influence the disappearance rate. On the island of St. Kitts, West Indies, we baited 45 stations (n=35 bait blocks, n=10 controls) at dawn and checked them twice daily for 4 consecutive days. This procedure was repeated after a two-day period, for each combination of season (dry and wet) and habitat type (mixed grassland, littoral and dry forest). We used the Kaplan-Meier method to estimate bait survival at 12 and 36 hours after baiting. Across all sites, control baits were removed faster than bait blocks, but by 36 hours, over 90% of all baits had disappeared. For bait blocks only, the disappearance rate was higher during the dry season and in the dry forest habitat compared to the other habitats. There was no difference between diurnal and nocturnal disappearance rates. While the exact species that consumed the baits remain uncertain, we found that mongooses readily remove bait blocks, along with non-native mammals (e.g., dogs and cats) and land crabs in littoral habitats. We suggest that the bait blocks used in this study may be suitable for use as an external bait matrix for ORV baits.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"50 1","pages":"236 - 241"},"PeriodicalIF":0.4,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67941168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We fitted 24 mongooses (15 males and nine females) with very high frequency (VHF) radio collars at the Cabo Rojo National Wildlife Refuge in southwestern Puerto Rico and tracked them via radio telemetry for up to six months. The raw mean (SE) minimum convex polygon home range among 24 mongooses was 45.03 (8.30) hectares. The mean (SE) fixed kernel 95% estimate was 38.37 (5.78) hectares, and the 50% core area estimate was 7.89 (1.29) hectares. Our home range estimates are similar to previous estimates in the Caribbean and other islands, but larger than those reported from their native range in India. Our study adds new information to the small body of literature available on mongoose home ranges and is one of the few studies conducted in a lowland dry semi-deciduous forest in southwestern Puerto Rico.
