Abstract

espanolLa Limnologia teorica es un tema olvidado en estos tiempos. Por eso, aqui proponemos un intento modesto de iniciar y promover teorias limnologicas, explorando las relaciones mecanicistas entre biogeoquimica, produccion, riqueza especifica y redes troficas para los tipos mas frecuentes de tamano de lago, que son los pequenos y medianos. Aunque el numero de estudios que ofrece resultados para apoyar dichas relaciones es bastante reducido, algunas bien conocidas de estas facilitan el organizar los lagos dentro de un esquema conceptual que usa la retencion del agua, el fosforo total y el carbono organico disuelto como variables de control. Considerar todas las variables de respuesta por unidad de superficie permitira pasar por alto el importante asunto de la profundidad, y el de la estratificacion termica por lo tanto. Nuestro esquema conceptual vislumbra siete tipos de lagos con conjuntos de respuestas unicas relativas a la riqueza de especies, la conectancia de las redes troficas, los flujos biogeoquimicos y la productividad lacustre. Una mayor concrecion de este modelo conceptual y la extension del mismo a todos los ambientes estancados (de los pequenos a los grandes) podran llevarse a cabo cuando haya mas datos sobre estos temas, probablemente teniendo en cuenta ademas alguna variable relativa al transporte horizontal. Tras esta contribucion, nos gustaria ver nuevos desarrollos teoricos que –ademas– presten atencion a la Limnologia mediterranea, la cual difiere un poco de la existente en las zonas templadas frias y tropicales del globo.

全面了解湖泊:重新审视生物地球化学、生物多样性、生产和食物网关系
西班牙理论湖沼学是当今被遗忘的话题。出于这个原因,在这里,我们提出了一种适度的尝试,以启动和促进湖泊理论,探索生物地球化学、产量、特定财富和湖泊大小最常见类型(中小型)的滋养网络之间的机械关系。虽然提供支持这些关系的结果的研究数量相当少,但其中一些众所周知的研究有助于在一个概念方案中组织湖泊,该方案将保水、总磷和溶解有机碳作为控制变量。考虑每单位面积的所有响应变量将忽略深度的重要问题,因此忽略热分层的重要问题。我们的概念方案概述了七种类型的湖泊,它们对物种丰富度、滋养网络的连接、生物地球化学通量和湖泊生产力有一系列独特的反应。当有更多关于这些问题的数据时,可以进一步具体说明这一概念模型,并将其扩展到所有停滞的环境(从小到大),可能还考虑到与横向运输有关的一些变量。在这一贡献之后,我们希望看到新的理论发展,这些发展也将关注地中海湖沼学,这与全球冷温带和热带地区的湖沼学略有不同。英语理论湖沼学是当今被忽视的话题。在这里,我们努力启动和促进湖泊学的理论发展,处理最常见的湖泊,即中小型湖泊中生物地球化学、生产、物种丰富和食物网之间的机制关系。虽然目前正在进行的支持包括这种关系的研究很少,但众所周知的相互作用使我们能够在一个自下而上的概念模型中建立这样的湖泊,该模型包括蓄水、总磷和溶解有机碳作为驱动变量。所有响应变量都是根据面积来查看的,这使得围绕深度(从而分层)的其他重要问题成为可能。七种湖泊类型被认为在物种丰富度、食物网络连接、营养通量和湖泊代谢方面具有独特的一系列特征。当有更多关于这些主题的数据时,可以将这一概念模型扩展和调整到所有分期水(从小到大),可能会考虑到横向运输的特点。我们期待着看到理论湖沼学的未来发展,并特别注意地中海的湖沼特征,这些特征与寒冷温度和热带地区的湖沼特征有所不同。

期刊介绍: Limnetica publishes original research articles on the ecology of inland waters. The scope of Limnetica includes the ecology of rivers, lakes, reservoirs, coastal lagoons and wetlands, as well as biogeochemistry, paleolimnology, development of new methodologies, taxonomy, biogeography and any aspect of theoretical and applied continental aquatic ecology such as management and conservation, impact assessment, ecotoxicology and pollution. Limnetica will accept for its publication scientific articles presenting advances in knowledge or technological development, as well as as papers derived from new practical approaches on the topics covered by the journal.
