Nearshore Habitat

DenseAcropora cervicornisaggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been published concerning the distribution and abundance ofA. cervicornisoutside of these known dense patches. The first goal of this study was to conduct a spatially extensive and inclusive survey (9.78 km2) to determine whetherA. cervicornisdistribution in the nearshore habitat of SE FL was spatially uniform or clustered. The second goal was to investigate potential relationships between broad-scale seafloor topography andA. cervicornisabundance using high resolution bathymetric data.Acropora cervicorniswas distributed throughout the study area, and the Getis-Ord Gi* statistic and Anselin Local Moran’s I spatial cluster analysis showed significant clustering along topographic features termed ridge crests. Significant clustering was further supported by the inverse distance weighted surface model. Ordinal logistic regression indicated 1) as distance from a ridge increases, odds of reducedA. cervicornisabundance increases; 2) as topographic elevation increases, odds of increased abundance increases; and 3) as mean depth increases, odds of increased abundance increases. This study provides detailed information onA. cervicornisdistribution and abundance at a regional scale and supports modeling its distributions in similar habitats elsewhere throughout the western Atlantic and Caribbean.Acropora cervicornisis frequently observed and in areas an abundant species within the nearshore habitat along the SE FL portion of the Florida Reef Tract (FRT). This study provides a better understanding of local habitat associations thus facilitating appropriate management of the nearshore environment and species conservation. The portion of the FRT between Hillsboro and Port Everglades inlets should be considered for increased management and protection to reduce local stressors.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

El objetivo fue estudiar la variabilidad genética de características morfológicas de maíces nativos en la Península de Yucatán (PY), México. Se utilizaron trece accesiones de maíz nativo reconocidas con el nombre de Naál Xóy, Xnúc Naál Blanco, Gallito Amarillo, Dzit Bacal, Mejeén Naál, Rosa San Juan, Cháck-Chóp, Teél Cháck, Sáck Teél, San Pableño, Ejú-Criollo Morado, Xmején Naál Tsitbacal y Clavo Chiapaneco. Los materiales se establecieron en Junio de 2017 y 2018, en Poxyaxum, Campeche, México, (19° 41´58.4´´ N, 90° 21´03.6´´ W y 30 msnm) bajo un diseño de bloques completos al azar con tres repeticiones. Los resultados revelaron diferencias (P£0.05) en las variables morfológicas evaluadas: número de días a floración masculina (FM) y femenina (FF) presento una inestabilidad de 12 días a FM y FF, con Naál Xóy y Ejú-Criollo Morado, y 15 días a madurez fisiológica con Clavo Chiapaneco. Una diferenciación de 98 y 126 cm en altura de mazorca y planta con Eju-Criollo Morado; 6 y 1.1 cm en longitud y diámetro de mazorca con Xnúc Naál Blanco y Cháck-Chóp, y Gallito Amarillo. Una variación de 4 hileras con Teél Cháck y 17 granos por hilera con San Pableño; 11 y 74 gr en peso de 100 granos (Xmején Naál Tsitbacal, Rosa San Juan y San Pableño) y granos por mazorca (Naál Xóy); y una diferencia mayor en rendimiento con Naál Xóy y Dzit Bacal de 3105 kg.ha-1.
