Environmental data from FCE LTER Caribbean Karstic Region (CKR) study in Yucatan, Belize and Jamaica during Years 2006, 2007 and 2008
Several studies have shown that within the Florida Coastal Everglades, periphyton mat properties, (incuding biomass, nutrient and organic content, and community composition) vary predictably in response to water quality.The Florida Coastal Everglades (FCE) wetland system is very similar with respect to climate, geology, hydrology and vegetation, to wetlands found in Jamaica, the Yucatan region of Mexico and parts of Belize. This study was therefore conducted to ascertain (i) the level of similarity between the periphyton diatom communities from karstic wetland sites in Belize, Mexico, Jamaica and comparable sites within the FCE, (ii) the relationship between periphyton biomass, TP levels and diatom community composition at these sites, and (iii) the feasibility of employing diatoms as indicators of water quality at these sites, using models relating diatom community composition to water quality from comparable sites within the FCE. Multiple wetland sites in Jamaica, the Yucatan region of Mexico and parts of Belize were visited between 2006 and 2008, during wet and dry seasons. At each site physico-chemical data were collected along with periphyton samples. The periphyton samples were processed in accordance with standard methods to obtain biomass, organic content and TP measures, and to identify and enumerate diatom and soft algae species. Various aspects of the diatom communities were then compared to previously compiled data on diatom communities from various parts of the FCE. SIMI analysis was used to determine the level of similarity between the systems and Non-Metric Multidimensional Scaling was used to identify relationships between diatom communities and water quality.

Fig. 19. Isolated p4 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica
Fig. 19. Isolated p4 (AMNHP 140816) of capromyid Isolobodon portoricensis from Salt River Bay, St. Croix (?Amerindian site), SEMs at low and high magnification. (A) Transverse section at low magnification, showing distribution of enamel (en), dentine (de), and cementum (ce). (B) Closeup of large boxed area in A, showing cementum and enamel. (C) Closeup of small boxed
Fig. 18. Isolated p4 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica
Fig. 18. Isolated p4 (AMNHP 140817) of Antillean heptaxodontine Elasmodontomys obliquus from Toraño Cave, near Utuado, Puerto Rico, SEMs at low and higher magnification. While this specimen was being cut, the apical end broke off, apparently along an undetected developmental boundary (feature 1 in A). The boundary as seen on the crown end is in contact with the tape (feature 2) used to position the specimen for SEM. (A) Longitudinal section through crown end at low magnification, showing distribution of enamel, dentine and cementum (occlusal surface faces left). (B) Closeup of boxed area in A, showing characteristic histological differences between cementum (ce), enamel (en), and dentine (de). (C) Transverse section through apical end at low magnification; pc, pulp chamber. (D) Closeup of boxed area in C, showing secondary dentine on wall of pulp chamber. Secondary dentine is less irregular in this taxon than in Amblyrhiza (fig. 17).
Fig. 17 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica
Fig. 17. Isolated molars of Antillean heptaxodontine Amblyrhiza inundata from Pitchapple Cave, Anguilla, SEMs at low and high magnification. (A) AAHS 91253a, longitudinal section at low magnification, showing distribution of enamel, dentine and cementum (root end faces top of page; pc, pulp chamber). (B) Closeup of boxed area in A, showing appearance of dentine in crown. (C) AAHS 91253b, transverse section through root end at low magnification, showing pulp chamber (to right of box). (D) Closeup of boxed area in C, showing characteristic appearance of dentine matrix in this region. In both specimens, the root end is nearly as long as the crown, indicating that they came from aged animals. In early ontogeny each pulp chamber would have been broadly open beneath the apical ends of the enamel folds. With continuing elaboration of dentine, the chambers became constricted and progressively elongated. Since root canals must be preserved to transmit neurovascular bundles, canals mark the previous extent and line of adapical movement of pulp chamber. In Amblyrhiza, both primary and seconday dentine have an irregular appearance, with (in addition to characteristic tubules) many small vacuities that presumably housed cell bodies. There is no histologically sharp dividing line between the crown and root areas.
Fig. 15 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica
Fig. 15. Occlusal aspect (stereopairs) of same specimens of Boromys torrei shown in figure 14, illustrating cheektooth wear stages 1–3 (A–C). See text for description and evaluation. Boromys was probably similar to Xaymaca in body size, but cheekteeth differ radically (e.g., in spiny rats, cheekteeth exhibit furcated roots, prominent cervix, and deep enamel infolds).
