Se presenta el primer listado de grupos de invertebrados bentónicos del sistema lagunar de Mandinga (SLM). Se realizaron siete colectas en temporadas de secas de 2008 a 2015 y una en temporada lluviosa de 2015. Los organismos endobénticos se colectaron con una draga y los organismos epibénticos, con una red tipo Renfro y chinchorro. Todos los organismos se identificaron hasta el nivel permisible. El listado está conformado por un total de 43 grupos zoológicos, distribuidos en ocho filos, siete clases, nueve órdenes, 16 familias y tres tipos de larvas. Los grupos Decapoda (10), Gastropoda (8), Amphipoda (4), Bivalvia (3), Tanaidacea (3) e Isopoda (3), fueron los más diversos, seguidos en menor medida por los grupos que se determinaron a niveles superiores a Familia (12). La diversidad de grupos es similar a la de otros sistemas costeros veracruzanos, donde los órdenes Decapoda, Amphipoda y Tanaidacea fueron los más diversos, seguidos por Isopoda. Los resultados de la presente investigación, representan un aporte importante para el conocimiento de la diversidad del sistema estudiado y de la distribución de los grupos en Veracruz y golfo de México.
本文介绍了曼丁加泻湖系统(SLM)底栖无脊椎动物的首次名单。在2008 - 2015年的旱季和2015年的雨季进行了7次收集。采用挖泥船收集内底生物,采用伦弗罗网和chinchorro网收集外底生物。所有生物都被识别到允许的水平。该名录共有43个动物类群,分为8门7纲9目16科3种幼虫。在本研究中,我们分析了四种不同的类群,它们的分布分布在不同的科中,分别是甲壳纲(10个)、腹足纲(8个)、两栖类(4个)、双壳类(3个)、Tanaidacea(3个)和等足类(3个)。类群多样性与韦拉克鲁斯其他沿海系统相似,其中十足目、片脚目和Tanaidacea目最多样化,其次是等足目。在墨西哥韦拉克鲁斯州和墨西哥湾州,对该系统的多样性和群体分布进行了重要的研究。

Brachybaenus domingensis sp. nov. of gryllacridids (Orthoptera: Stenopelmatoidea: Gryllacrididae) from Dominican Republic, Hispaniola 多明尼加Brachbaenus domingensis sp.nov.(直翅目:狭翅目:Gryllacididae)

The gryllacridid Brachybaenus domingensis sp. nov. is described and illustrated from specimens collected in various localities of the Dominican Republic. The morphology of the new species is compared to that of the Cuban species Brachybaenus cubensis (Brunner von Wattenwyl, 1888), which may be its closest relative. Although these species are similar, diagnostic features of B. domingensis are the yellowish coloration of the face, spines on the anterior tibiae shorter than the eye length, and wings that markedly surpass the abdominal end. In B. cubensis the face is mostly black, the spines in the anterior tibiae are as long or longer than the eye length and the wings barely surpass the abdominal end. This is only the second species of gryllacridids reported from Hispaniola, the fourth species of Brachybaenus Karny in the Caribbean and the 17th species of the genus.
从多米尼加共和国各地采集的标本中描述并说明了gryllacidid Brachybaenus domingensis sp.nov。将新物种的形态与古巴物种Brachybenus cubensis(Brunner-von Wattenwyl,1888)的形态进行了比较,后者可能是其最接近的亲属。尽管这些物种是相似的,但domingensis的诊断特征是面部呈黄色,胫骨前棘短于眼睛长度,翅膀明显超过腹部末端。库贝的脸大部分是黑色的,胫骨前部的棘与眼睛的长度一样长或更长,翅膀几乎不超过腹部末端。这只是从伊斯帕尼奥拉岛报告的第二个gryllacidids物种,加勒比海的第四个Brachbaenus Karny物种和该属的第17个物种。

 The population structure of Limia zonata (Nichols, 1915) was studied in four locations in the Maimón River, Monseñor Nouel province, Dominican Republic. The sex and adult-juveniles ratio was calculated for all sampled localities. It was found that the sex ratio of L. zonata was significantly different from 1: 1 and is biased towards females (1.0: 1.6). Juvenile fish were more abundant and frequent than adults (69.3%). More than 800 fish were measured and weighed to analyze the frequency of size classes, morphometry and body condition. Ten size classes were distinguished that vary in frequency according to sex. Total length of the specimens ranged from 6.50 to 65.69 mm, while weight varied between 0.004 and 3.941 g. The morphology varied between sexes and a pronounced sexual dimorphism was found. All the morphometric variables studied showed a high level of association (r). The adjustment of the regression models (r2) of the morphometric relationships was between 85% and 99%. The relationship between the standard length and the total weight was reflected in the rates of growth. The Relative Condition Factor (Kn) demonstrated the good state of health of this fish population, but also variations between the sexes were detected.
在多米尼加共和国Monseñor Nouel省Maimón河的四个地点研究了Limia zonata (Nichols, 1915)的种群结构。计算了所有采样地点的性别和成幼比。结果表明,水蛭的性别比明显高于1:1,偏向于雌性(1.0:1.6)。幼鱼数量和频率均高于成鱼(69.3%)。研究人员对800多条鱼进行了测量和称重,以分析鱼的体型、形态和身体状况。根据性别的不同,我们区分出了10个大小类别,它们的频率不同。试件总长度为6.50 ~ 65.69 mm,重量为0.004 ~ 3.941 g。形态在两性之间存在差异,并发现了明显的两性二态性。所有研究的形态计量变量均显示出高水平的相关性(r)。形态计量关系的回归模型调整(r2)在85% ~ 99%之间。标准长度和总重量之间的关系反映在生长率上。相对条件因子(Kn)表明该种群的健康状况良好,但也发现了性别之间的差异。

Natural and anthropogenic factors as taphonomic agents in the differential preservation of paleontological remains from the fossil deposit “Las Llanadas”, Central Cuba 自然因素和人为因素在古巴中部“拉斯拉纳达斯”化石矿床古生物遗迹的不同保存中作为埋藏学因素

The results of a taphonomic analysis carried out on the vertebrate fossil deposit “Las Llanadas”, Sancti Spíritus, Cuba, are presented. The origin of the deposit is analyzed through features of the accumulated sediments, combined with the geological structure of the study area. The type of fossiliferous deposit represented was determined according to the categorizations proposed for Cuba by several authors. Differential preservation registered, between the recent material and the fossil and subfossil material, was analyzed by considering the mechanisms of taphonomic alteration identified as direct evidence of specific biostratinomic and fossildiagenetic processes to which the extracted remains were subjected. Anthropogenic and natural factors are discussed as responsible for the current accumulation features of the deposit. The historical reconstruction of the paleontological interventions on the site, during the last century, had been an important element to understand the features of the current fossil assemblage.
介绍了对古巴Sancti Spíritus的脊椎动物化石沉积物“Las Llanadas”进行的分类分析结果。通过沉积特征,结合研究区地质构造,分析矿床成因。所代表的化石矿床类型是根据几位作者为古巴提出的分类确定的。研究人员分析了新近材料与化石和亚化石材料之间的差异保存,并考虑了地层蚀变的机制,这些机制被确定为提取的遗骸所经历的特定生物层组学和化石成岩过程的直接证据。讨论了造成该矿床当前成藏特征的人为因素和自然因素。在上个世纪,对该遗址进行古生物学干预的历史重建,是了解当前化石组合特征的重要因素。

Differential preservation registered, between the recent material and the fossil and subfossil material, was analyzed by considering the mechanisms of taphonomic alteration identified as direct evidence of specific biostratinomic and fossildiagenetic processes to which the extracted remains were subjected. Anthropogenic and natural factors are discussed as responsible for the current accumulation features of the deposit. The historical reconstruction of the paleontological interventions on the site, during the last century, had been an important element to understand the features of the current fossil assemblage.","PeriodicalId":33102,"journal":{"name":"NOVITATES CARIBAEA","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48156504","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}

Reduced biodiversity and high number of endemics characterize island ecosystems. Island natives and endemics are considered more vulnerable than continental species to exotic species invasions and habitat changes. The effect of replacing a native forest by an exotic wood plantation was studied on the assemblage of native and endemic ant species. The main hypothesis was that endemic and native ant species were more vulnerable to habitat changes than the exotic ant species. Nevertheless, it was found that native ants were more numerous and specious in both native and exotic plantations. Also, high numbers of two endemic ants were detected within exotic plantations, while only one exotic ant Hypoponera opacipeps was relatively abundant, particularly on native forest. In conclusion, exotic ant species did not dominate the communities studied nor the native and endemic ant assemblages seemed to be affected negatively by the forest replacement.
生物多样性减少和大量地方性疾病是岛屿生态系统的特征。与大陆物种相比,岛屿原生物种和特有物种被认为更容易受到外来物种入侵和栖息地变化的影响。研究了外来人工林替代原生林对本地和特有蚁群的影响。主要假设是,特有和本地蚂蚁物种比外来蚂蚁物种更容易受到栖息地变化的影响。然而,我们发现在本地和外来人工林中,本地蚂蚁的数量和数量都更多。此外,在外来人工林中发现了大量的两种特有蚂蚁,而只有一种外来蚂蚁(Hypoponera opacipeps)相对丰富,特别是在原生森林中。综上所述,外来蚁种不占研究群落的主导地位,本地和特有蚁群也不受森林替代的负面影响。

Se realizó un inventario de los reptiles presentes en el área protegida y refugio de vida silvestre El Cañón del río Gurabo o Furnia de Gurabo, localizada al suroeste del municipio de Mao, provincia Valverde, República Dominicana. Se registran 15 especies para la zona, agrupadas en 10 familias y 12 géneros. Se amplía la distribución del gecko gigante de la Hispaniola, Aristelliger lar.
对多米尼加共和国瓦尔韦德省茂市西南部的古拉博河峡谷或古拉博富尼亚野生动物保护区内的爬行动物进行了清查。该地区记录了15种,分为10科12属。西班牙裔巨型壁虎Aristelliger Lar的分布范围扩大。
