Despite their critical role as the main energy pathway between phytoplankton and fish, the functional complexity of zooplankton is typically poorly resolved in marine ecosystem models. Trait-based approaches-where zooplankton are represented with functional traits such as body size-could help improve the resolution of zooplankton in marine ecosystem models and their role in trophic transfer and carbon sequestration.

Links between fish abundance and ocean biogeochemistry as recorded in marine sediments
/
Kavanagh, Lucas (McGill University, Montréal. Department of Earth and Planetary Sciences) ;
Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Fish populations are linked to ocean biogeochemistry by their reliance on primary production for food, and dissolved oxygen to breathe. It is also possible that marine fish modify biogeochemical dynamics, as do freshwater fish, through top-down trophic cascades, but there has been relatively little consideration of this possibility. [...]

Spatial patterns in the abundance of species are determined by local abiotic and biotic conditions, and by the movement of individuals among localities. For species distributed among discrete habitat "islands", such as zooplankton distributed among lakes, local conditions within lakes often dominate low movement rates among lakes to determine the composition of communities.

The limnological characteristics and zooplankton community of a newly created site : the Pareja Limno-reservoir

The creation of dams in the riverine zone of large reservoirs is an innovative action whose primary goal is to create water bodies that ensure a stable level of water there. We have termed these bodies of water "limno-reservoirs" because their water level becomes constant and independent of the fluctuations occurring in the main reservoir. [...]
Los denominados diques de cola constituyen una actuación novedosa cuyo objetivo es generar una lámina de agua constante en sectores de cola de grandes embalses. Para dichas masas de agua hemos propuesto el término "limnoembalses", pues con ellos se genera permanencia en el nivel del agua frente a las variaciones inherentes a la gestión del embalse ordinario, suponiendo además una actuación ambiental de car'acter compensatorio y/o corrector.

Trophic interactions in shallow lakes of the Pampa plain (Argentina) and their effects on water transparency during two cold seasons of contrasting fish abundance Trophic cascade interactions in shallow lakes have been studied extensively in the north temperate region mainly during the summer periodo However, fewer studies have examined these interactions in warrner regions during the winter periodo The aim of the present work was to study trophic cascade interactions and their effect on water transparency in small lakes in the Pampean Plain (Argentina) during the cold season. [...]
Las interacciones tróficas en cascada han sido ampliamente estudiadas en los lagos someros del hemisferio norte, principalmente durante la temporada estival. Sin embargo, su estudio ha sido menos frecuente en los lagos de regiones más cálidas durante la estación fría del año. [...]

This study shows the results of an extensive survey carried out in spring 2007 on 120 farrn ponds in Andalusia (South of Spain). Pond use was diverse, but the most common uses were irrigation of vast areas of land and livestock watering. [...]
Se presentan resultados de un muestreo extensivo de 120 balsas de riego llevado a cabo en la primavera de 2007 en Andalucía (Sur de España). Los datos de zooplancton revelan una inesperada riqueza de especies en estos cuerpos de agua, que no habían sido estudiados hasta la actualidad, porque muchos de ellos son de reciente creación y están en propiedad privada.

The zooplankton of eight restored peridunal ponds located in L' Albufera Natural Park (Valencia, Spain) was sampled fortnightly from November 2006 to July 2007 to study the effect of hydroperiod, restoration and other environmental variables in the zooplankton community structure. [...]
El zooplancton de ocho charcas peridunares del Parque Natural de L'Albufera (Valencia, España) se siguió quincenalmente desde Noviembre 2006 a Julio 2007 para conocer el efecto del hidroperiodo, de la restauración y de otras variables ambientales en la estructura de la comunidad zooplanctónica.

In the Pampean Region, there are numerous lagoons of diverse forms, sizes and hydrography. The knowledge about these ecosystems in these lagoons is limited, especially about the plankton present in them. [...]

The use of the role of the species in the habitat (the niche), as an alternative to systematics for studying the processes that determine which and how many species live in a specific habitat (community assembly), is an approach that has been limited by the difficulties in the characterization of the niche. [...]
La utilización del papel de las especies en el habitat (el nicho), como alternativa a la aproximación sistemática, en el estudio de los procesos que determinan cuales y cuantas especies pueden coexistir en un determinado espacio (ensamble de comunidad), se ha visto limitada por las dificultades que existen para caracterizar el nicho.
