Most of these species have been collected in deep waters from localities in the South Atlantic and Pacific Oceans, and only one species has been found in the Mediterranean Sea. Many oediceroids inhabit waters more than 200 meters deep with only four species confined to shallow waters. This is the first occasion in which a species belonging to the genus Oediceroides is recorded for the Gulf of Mexico. Here, we describe O. improvisus sp. nov., a species of marine deep-water amphipod collected in 925 meters of water. This species has carapace, mouthpart and pereopodal characters that unite it with other members of the genus. It differs from all other species due to unique rostral and pereopod seven characters, all discussed in detail further in this description. To date, only 20 deep-sea (>200 meters) benthic amphipods have been recorded in the Gulf of Mexico, in comparison with more than 200 species of shallow water representatives from the same region. Our study provides evidence that the deep waters of the Gulf of Mexico still hold undescribed biodiversity.","PeriodicalId":33102,"journal":{"name":"NOVITATES CARIBAEA","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47415111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some studies have questioned the generality of the assumptions and predictions of this hypothesis suggesting that other factors different to temperature gradients between low and high elevations may explain altitudinal distribution of species in the tropics. In this study we test some predictions of the Janzen’s hypothesis at local scales through the analysis of the individual thermal niche breadth in populations of livebearing fishes of the genus Limia and its relationship with their altitudinal distribution in some islands of the Greater Antilles. We assessed variation in tolerance to extreme temperatures (measured as critical thermal minimum (CTmin) and maximum (CTmax) and compared thermal breadth for populations of eight species of Limia occurring in three Caribbean islands and that occupy different altitudinal distribution. Our results showed that species analyzed had significant differences in thermal limits and ranges. Generally, species distributed in high and low elevations did not differ in thermal limits and showed a wider range of thermal tolerance. However, species living in mid-elevations had narrower range of temperature tolerance. We found no significant effect of phylogeny on CTmin, CTmax and thermal ranges among species. This study did not provide evidence supporting Janzen’s hypothesis at a local scale since thermal tolerance and altitudinal distribution of Limia species were not related to temperature gradients expected in nature. Phylogeny also did not explain the patterns we observed. We suggest that biotic factors such as species interactions, diet specializations, and others should be considered when interpreting current distribution patterns of Limia species.","PeriodicalId":33102,"journal":{"name":"NOVITATES CARIBAEA","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46906682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El objetivo de este trabajo fue estudiar la composición y abundancia de la macrofauna bentónica en los bancos ostrícolas (C. virginica) de las lagunas Pueblo Viejo, Tamiahua y Tampamachoco, Veracruz, México. Se realizaron muestreos mensuales en tres bancos ostrícolas por laguna costera. Los organismos fueron extraídos con el arte de pesca “gafas”. La información obtenida se utilizó para estimar la riqueza de especies, abundancia, equitatividad y diversidad verdadera a nivel mensual por laguna costera. Además, se determinaron diferencias significativas mediante análisis de similitud y ordenación. Se recolectó un total de 1 606 ejemplares del macrobentos en las tres lagunas, identificando 28 especies, 24 familias, 18 órdenes distribuidos en seis grupos zoológicos: Porifera, Platyhelminthes, Annelida, Mollusca, Arthropoda y Bryozoa. Mollusca y Annelida fueron los de mayor riqueza y abundancia de especies. Los bancos ostrícolas de la laguna Tampamachoco fueron más diversos en especies (27 taxa) y abundantes (857 individuos) en comparación a Pueblo Viejo y Tamiahua. Epibiontes filtradores caracterizaron los bancos ostrícolas representados por Brachidontes exustus (en Pueblo Viejo), Amphibalanus eburneus e Hydroides dianthus (ambas en Tampamachoco). Mientras en Tamiahua, las más representativas fueron carnívoros: Nereis oligohalina y Stylochus ellipticus. Para las tres lagunas estudiadas, los valores de la riqueza, abundancia y equitatividad fueron homogéneos en los meses estudiados. Los bancos ostrícolas de cada laguna costera presentan un ensamblaje macrofaunístico propio, dado que se determinaron diferencias significativas con base en la riqueza y abundancia.","PeriodicalId":33102,"journal":{"name":"NOVITATES CARIBAEA","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41655825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para estimar la densidad e intensidad de pastoreo de Scaridae y Acanthuridae y su relación con la cobertura de macroalgas, se seleccionaron dos veriles en el Parque Nacional Guanahacabibes (PNG) y uno en La Habana (LH), este último con elevada degradación antrópica. Se usaron video-cuadrantes de 1 m2 para obtener la densidad de peces (individuos/m2) e intensidad de pastoreo (mordidas/5 minutos*m2) y cuadrantes de 25x25 cm para la abundancia relativa de macroalgas. Se identificaron diez especies, Scaridae predominó en el PNG y Acanthuridae en LH. La pérdida de Scaridae en LH, implica que Acanthuridae representa un exceso de un grupo funcional que no provee el sustrato desnudo para el reclutamiento coralino. Hubo fuerte correlación positiva entre la densidad e intensidad de pastoreo de Scaridae con Halimeda, dado que en el PNG esta alga se favorece y constituye un alimento recurrente y eficiente para Scaridae. En LH predominaron algas bioindicadoras de eutrofización como Stypopodium y sólo mostró correlación positiva con Acanthuridae. Estos peces consumen las epífitas sobre Stypopodium, y sus tasas de pastoreo son más altas, lo cual contribuye al cultivo de algas cespitosas, fuertes competidoras del espacio con los corales. De ahí la importancia de presentar comunidades más equitativas con diferentes grupos funcionales de peces herbívoros que contribuyan a un control más efectivo de las macroalgas.","PeriodicalId":33102,"journal":{"name":"NOVITATES CARIBAEA","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45650875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
