The description of benthic and associated fish assemblages in remote areas, supposedly less vulnerable to human stressors, is necessary to better understand the spatial extent of declining trends, and to target areas for special management and protection. We present results from an expedition to Silver Bank (SiBa), Dominican Republic, aimed at providing the first quantitative assessment of benthic and fish assemblages in the area in the last 20 years. In April 2022, seven sites were surveyed using the Global Coral Reef Monitoring Network and the Atlantic Gulf Rapid Reef Assessment protocols, to determine benthic composition, coral richness, prevalence of diseases, invertebrates, and fish assemblages. Contrary to our expectations, reefs showed severe signs of deterioration, with coral cover seldom exceeding 11% on average, with no more than 14 species (from the more than 60 for the Caribbean region). Turf algae and macroalgae dominated the reefs (37–90%). Coral disease prevalence did not exceed 1–2%, and no evidence of epizootic Stony Coral Tissue Loss Disease (SCTLD) was noticed. Clear signs of overfishing were recorded, with carnivores above 15 cm being scarce across all sites. Furthermore, herbivorous species also depicted sizes below 15 cm, with no more than eight species. Our results change the previous conception that reefs at Silver Bank are healthier than coastal reefs because they benefit from low anthropogenic pressures. This serves as an alert to local environmental authorities to improve surveillance and management actions to preserve this area.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"74 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114301","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}

Buffelgrass is an African C4 bunchgrass that has been introduced outside its native range for rangeland improvement and livestock feed. In the Caribbean region, it has been introduced to supplement managed pasturelands and can have an effect on the surviving native flora. To determine the potential range where these populations might be present in tropical dry forest biomes in the next decades, we ran species distribution models for the Puerto Rican bank. We found that buffelgrass will remain present in the tropical dry forest biome of the main island of Puerto Rico as well as nearby islands with equal or greater biodiversity refuges. With the increase in atmospheric greenhouse gases, more areas of Puerto Rico's coasts and nearby islands will become suitable habitat for this invasive grass. Those areas should be actively monitored for control and removal of this invasive grass.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739032","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}

However, no recent works have focused primarily on the ants of urban and suburban areas. In this study, we assessed the species richness and origin of ants in urban and suburban areas of St. Andrew, Jamaica. Ant specimens were hand-collected within a 30 m radius area during a 15 minute search conducted at 27 sample sites during 39 sampling events. A total of 31 ant species were collected, representing a mixture of 18 native (58.1%) and 13 introduced (41.9%) species. Among the 18 species native to the Caribbean region, three (9.7%) are endemic to Jamaica, namely Camponotus hannani, Camponotus fugax, and Cephalotes jamaicensis. Sixteen tramp species (species with a worldwide distribution) represented 51.6% of the ant community, including Brachymyrmex patagonicus, Nylanderia steinheili, Paratrechina longicornis, Tapinoma melanocephalum, and Trichomyrmex destructor. Brachymyrmex patagonicus, Solenopsis geminata, and P. longicornis were most prevalent, being respectively found at 92.6%, 85.2%, and 81.5% of the sampled sites. Brachymyrmex obscurior, Camponotus fugax, Camponotus sexguttatus, Crematogaster steinheili, and Pheidole subarmata were among the least prevalent, each found at only one site. This publication presents the first published records of Solenopsis globularia and Monomorium pharaonis in Jamaica, with short descriptions of their habitats. The urban and suburban ant community of St. Andrew presents a relatively high species richness.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"53 1","pages":"59 - 67"},"PeriodicalIF":0.4,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41312767","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}

The specimens used in the analysis were obtained from traps baited with decomposing chicken in Jamaica, and 16 males were used in the morphometric analysis of the species. The antennae of B. orbitalis exhibit the typical characteristics of cyclorrhaphan Diptera, with the scape, the pedicel, and the postpedicel that bears the arista. The distribution, number, and location of sensilla on the antennae are described. Five types of sensilla were observed. The scape and pedicel have only chaetic sensilla, the postpedicel bears trichoid, basiconic, coeloconic sensilla, and clavate sensilla. Basiconic sensilla were the most numerous sensilla found on the antennae. Coeloconic sensilla are short-pegged and located in sunken depressions. The ventral surface of the postpedicel bears one sensory pit. This study provides additional information about the structure of the antennae in Sarcophagidae. This can be used to compare evolutionary relationships and identify shared characteristics.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"53 1","pages":"51 - 58"},"PeriodicalIF":0.4,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46732367","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}
