| Se determinó la variación espacio-temporal de la biomasa de los grupos morfo-funcionales de macroalgas y su relación con las variables ambientales: temperatura, salinidad, oxígeno disuelto y precipitaciones en dos localidades (laguna y playa) de pastizales al Norte de Ciego de Ávila desde marzo de 2010 a febrero de 2011. Las colectas se realizaron utilizando marco cuadrado de 25 cm de lado y se tomaron 15 unidades de muestreo en cada sitio. Se determinaron cinco grupos morfo- funcionales: foliosas y globosas, coriáceas, filamentosas, corticadas y calcáreas articuladas, presentando variaciones espacio- temporales los dos últimos. La laguna tuvo menor diversidad algal (13 géneros) y mayor biomasa total determinado por... |

| En las últimas décadas ha ocurrido un deterioro acelerado de los arrecifes de coral debido al efecto sinérgico de impactos naturales y antrópicos. En consecuencia, el objetivo de la tesis es evaluar los efectos acumulativos producidos por agentes estresantes múltiples y que impactan de forma simultánea los corales hermatípicos. Para ello se estimaron indicadores ecológicos en los niveles de comunidad y población. Los resultados obtenidos en esta investigación evidencian cambios en la estructura de las comunidades de corales que se asocian con el impacto antrópico directo existente a lo largo de la costa noroccidental de Cuba y que disminuye en la dirección este-oeste. Los indicadores ecológicos referidos a las tallas de los corales, muestran... |

| La expansión de la industria camaronícola depende de un adecuado conocimiento del proceso de reproducción que permita desarrollar programas de domesticación. El potencial reproductivo de los camarones domesticados al ser transferidos a condiciones de maduración depende, en buena parte, de la condición previa en la que se encuentran. Los indicadores más importantes relacionados con esta condición y que se analizan en el presente trabajo en relación a la edad y el tamaño de los camarones son: el grado de desarrollo ovárico y testicular, la calidad espermática y los niveles de reservas energéticas en Litopenaeus vannamei. Adicionalmente, se evaluó la posibilidad de establecer criterios predictivos de un óptimo potencial reproductivo en machos. En primer... |

| El mejillón verde Perna viridis (Linnaeus, 1758) nativo del Indo Pacífico, fue reportado en Cuba por primera vez en el año 2005, en la Bahía de Cienfuegos. Una de las alternativas propuestas para reducir el impacto de esta especie invasora en nuestro territorio fue su evaluación con fines de extracción y comercialización. Por tal, el problema de nuestra investigación fue analizar si el mejillón verde de la bahía de Cienfuegos era un alimento inocuo para el hombre. Nos trazamos como objetivo principal la caracterización del mejillón verde (Perna viridis) de la Bahía de Cienfuegos como posible alimento para el consumo humano. Para abordar este tema, se realizó un análisis de la fracción comestible del molusco y de su composición proximal. Además... |

| La investigación se realizó en los meses de octubre de 2011 y marzo de 2012. A partir del análisis de imágenes satelitales se seleccionaron 41 sitios en el sector central del golfo de Ana María, región surcentral de Cuba. En dichos sitios se llevó a cabo el inventario de corales, gorgonias y esponjas. Para los corales, se analizó, además, el estado de salud. El inventario se realizó en los ecosistemas de manglar, pastizales y arrecifes de coral (biotopos de cabezos y fondos areno-rocosos). El número de especies encontradas de corales fue de 41; de gorgonias, 23 y de esponjas, 41. Los corales más abundantes fueron Porites astreoides, Millepora alcicornis, Siderastrea siderea, Siderastrea radians, Agaricia agaricites. La mayor biodiversidad se... |

| Since the beginning of the 1990s a new rural development policy, which has later been called the "new rural paradigm" by the OECD, has received increasing attention in the European Union (EU) and elsewhere. It is expected that these policy measures attenuate social and economic problems in rural areas on a broader basis than the agricultural sector alone. They support local stakeholders like non-governmental organizations, local governments and local businesses in implementing local development strategies that are based on endogenous potentials and spatial interaction. Polish rural inhabitants, suffering among many other issues, from a lack of nonagricultural jobs, an unfavorable business environment and an insufficient public infrastructure, pinned high... |

| On the verge of EU accession, Poland’s agricultural sector is characterised by a number of distinct structural weaknesses, which are a major reason for the unsatisfactory income situation of rural households. Among these weaknesses are that farm productivity is substantially below EU standards, investment has performed much weaker as compared with the overall Polish economy, and structural change has been very small. It has been suggested that credit access is a crucial factor for overcoming these undesired outcomes. Furthermore, the Polish government massively intervenes on rural credit markets, in particular by granting subsidies on working capital and investment loans for agriculture. Against this background, the aim of the present research is to... |

| El estudio de la etapa larval de Atractosteus tristoechus fue realizado a través del análisis morfo-fisiológico bajo condiciones de cultivo a 28o C, desde la eclosión hasta los 18 días después de eclosionadas (DDE) las larvas. Se identificaron y describieron tres etapas de desarrollo: adherida 0-3 DDE, de transición 4-10 DDE y libre nadadora 11-18 DDE. Las tasas de crecimiento fueron de 1,30 mm/d y 10,2 %/d, encontrándose una desaceleración en la segunda etapa que coincide con las mayores alometrías, lo que indica fuertes cambios morfogénicos. En esta etapa crítica es donde ocurre el agotamiento del vitelo y la transición de la alimentación endógena a exógena. A los 4 DDE el tracto digestivo está diferenciado... |

| In 2017, the dominant greenhouse gases released into Earth’s atmosphere—carbon dioxide, methane, and nitrous oxide— reached new record highs. The annual global average carbon dioxide concentration at Earth’s surface for 2017 was 405.0 ± 0.1 ppm, 2.2 ppm greater than for 2016 and the highest in the modern atmospheric measurement record and in ice core records dating back as far as 800 000 years. The global growth rate of CO2 has nearly quadrupled since the early 1960s. With ENSO-neutral conditions present in the central and eastern equatorial Pacific Ocean during most of the year and weak La Niña conditions notable at the start and end, the global temperature across land and ocean surfaces ranked as the second or third highest, depending on the dataset,... |

| The recent extinction of the Caribbean monk seal Monachus tropicalis has been considered an example of a human-caused extinction in the marine environment, and this species was considered a driver of the changes that have occurred in the structure of Caribbean coral reef ecosystems since colonial times. I searched archaeological records, historical data, and geographic names (used as a proxy of the presence of seals) and evaluated the use and quality of these data to conclude that since prehistoric times the Caribbean monk seal was always rare and vulnerable to human predation. This finding supports the hypothesis that in AD 1500, the Caribbean monk seal persisted as a small fragmented population in which individuals were confined to small keys, banks, or... |

| Toxic algae producing an array of bioactive compounds may accumulate in shellfish, which in turn cause poisoning, following human consumption of contaminated shellfish. The chemistry, occurrence and toxicity of the toxins involved was reviewed. Following this review, the risk analysis and management processes are outlined for the production of shellfish. Subsequent sections describe five elements of risk characterisation to which my studies have significantly contributed: methods of analysis, distribution of toxins in the marine environment, preparative isolation of toxins, quality control tools in the determination of the toxins and characterisation of the chemical hazard in terms of lipophilicity, stability, reactivity and toxicity. The use of liquid... |

| A strong interest has been focused from several years on the algae pathway for energy production, especially for transportation fuels called third generation biofuel or G3 biofuel, and mainly from microalgae route, considering it could be a high potential alternative strategy for renewable energy and fuel production. Algae, and especially microalgae, present significant advantages compared with land resources, such as much higher productivity and lack of competition with food applications. Nevertheless, based on current knowledge, the production of an algae biomass for energy remains a difficult target to reach, due to the numerous existing hurdles such as the energetic yield and the economic positioning, without neglecting the environmental and societal... |
