The Caribbean is a biodiversity hotspot due to its rich biodiversity and wholesale loss of primary vegetation. Yet, there is a paucity of studies on the status and trends of terrestrial avifauna populations in the region. We combined survey data from six habitats (Quill and Gilboa Hill, Town, Botanical Garden, Garden Road, and Venus Bay) on a small Lesser Antillean island over a seven-year period. Species abundance and richness varied among habitats, with Town having the highest species richness. Logistic regressions revealed significant differences among habitat and year (P = 0.008), but not foraging guild, season, rainfall or elevation (P > 0.05). The Quill (P = 0.0003) and Town (P = 0.001) differed significantly from the other habitats surveyed. Granivorous + frugivorous and omnivorous species were most commonly detected in the Quill, whereas nectarivores and granivores were most commonly detected in Town. The influence of total annual precipitation on bird detection rates was unsubstantial. However, site-specific climate data for the different habitats are not available. Though resident landbird populations on St. Eustatius were stable over the survey period, we recommend that annual monitoring continue in the same habitats, especially following extensive vegetation damage caused by hurricanes Irma and Maria in September 2017 and in light of predicted global climate change. The results of our monitoring proved useful in evaluating protected areas and Important Bird Areas compared with non-protected areas. We encourage island researchers and conservation stewards to initiate similar long-term monitoring in order to determine the status of their resident landbird populations.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"50 1","pages":"23 - 36"},"PeriodicalIF":0.4,"publicationDate":"2020-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46275605","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}

Trinidadian guppies (Poecilia reticulata) are able to adapt to various environmental conditions and are even among the few species that can tolerate extensive pollution. In the Pitch Lake of Trinidad they live in highly toxic waters due to natural seepage of oil and bitumen. In this paper, we describe phenotypic divergence in several life-history traits between guppies from the Pitch Lake and from a nearby reference site with waters not polluted by bitumen/oil. We show that guppies from the Pitch Lake were (i) smaller and (ii) had a higher reproductive investment than those from the reference site. Furthermore, they (iii) produced more and smaller offspring. These results are congruent with a scenario of high mortality caused probably by a combination of water toxicity and higher predation than at the reference site. We therefore propose the Pitch Lake as an ideal system to study the effects of long-term (natural) water pollution on fishes, which might provide interesting insights into adaptation to extreme environments, and might further help to predict fish responses to anthropogenic pollution.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"49 1","pages":"255 - 262"},"PeriodicalIF":0.4,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49487743","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}

Aruba, Bonaire, and Curaçao (ABC Islands) are located at the southern margin of the Caribbean Plate, just north of South America. Little is known of the arachnid fauna of these islands, and the only work on spiders was published over a century ago. Here we provide a list of arachnids opportunistically collected from the islands, including Klein Bonaire and Klein Curaçao, over approximately 2 months. More than 750 specimens from 4 arachnid orders, (Amblypygi, Pseudoscorpiones, Scorpiones, Araneae) were collected and identified. We recovered 1 species of amblypygid, 2 species of pseudoscorpions, 1 species of scorpion, and 76 species of spiders. Additionally, we compared species diversity between urban and natural areas. The number of species is relatively low given the proximity to South America, but this likely reflects that collecting only took place for a short time and was opportunistic as opposed to systematic. Nevertheless, we found 25 new records and >20 likely undescribed species for the islands, providing insights into the spider fauna of northern South America and indicating that additional surveys of the area are warranted.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"49 1","pages":"125 - 140"},"PeriodicalIF":0.4,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47156571","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}

Fossil holoplanktonic mollusks (pteropods and heteropods) are so far little known from Trinidad and have not yet been employed in paleoenvironmental studies in this region. Specimens >125 µm were examined in samples from two sections of the Middle Miocene Brasso Formation of Central Trinidad. Samples from the type section at Brasso Village were younger (planktonic foraminiferal Zones N11–N12) than those from Nollis Tunnel, near Tabaquite (N8). Both sections yielded abundant holoplanktonic molluscs, but all were juveniles. At Brasso Village, yields were highest in samples collected near a bathyal oxygen minimum zone (OMZ) that was revealed using benthic foraminifera. The percentage of the fauna as Vaginella sp. did not vary significantly throughout this section, while Heliconoides sp. was concentrated in rocks deposited near the OMZ base and Creseis spina above the OMZ core. This implies depth stratification among the pteropods that limited the flux of Heliconoides sp. to shallower water samples. The fauna from Nollis Tunnel, where recovery was restricted to eight out of nine samples, was used to infer the position of the OMZ at this site. The assemblage was more abundant at Nollis Tunnel than at Brasso Village. Simultaneous confidence intervals show that the proportional abundance of Vaginella sp. did not vary significantly throughout the Nollis Tunnel section, while Creseis roesti and Heliconoides inflatus inflatus? showed depth stratification. This demonstrates that fossil holoplanktonic gastropods have potential as a tool for paleoenvironmental interpretations, especially in detecting fossil OMZs.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"49 1","pages":"150 - 156"},"PeriodicalIF":0.4,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45138104","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}

Ophioderma cinerea (Müller & Troschel, 1842) is a species of warm water ophiuroid that lives primarily in rocky habitats in the tropical Atlantic. Competition for resources can be high in their habitat. Behavioral observations in aquaria led to a hypothesis that differences in body size may affect feeding strategies, and thus affect survivorship. It is widely accepted that echinoderm ontogenic growth is sigmoidal, with juveniles growing much faster than adults. Yet, it is not understood what affect this has on behavior. Individuals were kept in replicate experimental tanks. After a 3-d starvation period, each individual was exposed to a proteinaceous food stimulus. The animals were observed and a time measurement was taken to determine how long it took the animals to sense the food and to begin moving toward the food during both day and night. Smaller individuals were found to sense food significantly faster than larger ones, while no difference was observed for time-to-motion. Several explanations may support this finding. One of these explanations highlights how the need to compete with larger animals may have selectively adapted ontogenetically more sensitive chemoreceptors in smaller animals.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"49 1","pages":"185 - 191"},"PeriodicalIF":0.4,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44916032","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}

This article shows how archaeological and geological data can be used to visualize the ‘invisible’ production of salt through solar evaporation in the archaeological record. Evidence of salt exploitation from natural salt ponds is difficult to obtain using standard archaeological methods, limiting our ability to assess the significance of these practices in the past. Salt, however, was an important and valuable resource in many different cultural contexts. This study follows on previous research of a precolonial site on Middle Caicos, Turks & Caicos Islands, which suggested a relationship between this settlement and the exploitation of salt at the adjacent natural salt pan. Coring techniques were used to visualize and determine the pre-colonial availability of salt at MC-6. Stratigraphic sequences in the salt pond provided a detailed perspective on the pond's dynamic past and confirmed that salt production was possible in precolonial times. The research presented here tested the applicability of phosphorus and chloride values and X-ray diffraction of soil to identify precolonial salt production. Data from the site and the pond suggest that people settled the village as soon as the pond began producing salt, linking the presence of people to the availability and possible exploitation practices of salt.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":"49 1","pages":"263 - 280"},"PeriodicalIF":0.4,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45677948","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 goal of this study was to characterize infaunal assemblages from a calcareous sponge, Clathrina lutea, across multiple reefs from the La Parguera Natural Reserve, Puerto Rico. The associated fauna from 43 C. lutea specimens yielded a total of 2,249 associated infauna distributed in seven invertebrate phyla. Arthropoda was the most abundant phylum accounting for 62.5% of total abundance, followed by Annelida (21.0%) and Nematoda (5.5%). Limited patterns of temporal or spatial variability were surmised due to the opportunistic sampling effort afforded to this investigation from the cryptic nature of this species. A concordance between our data set and those for the class Demospongiae were observed, with the most abundant associated fauna being copepods and polychaetes.
