Biological assessment of European lakes: ecological rationale and human impacts

Brucet Balmaña, Sandra; Poikane, Sandra; Lyche-Solheim, Anne; Birk, Sebastian (Wiley-Blackwell, 2013)

1. Nearly one hundred biological methods are currently used to assess the ecological status of European lakes. Here, using information from a questionnaire, complemented with findings from the literature, we compared the ...
Climate change impacts on lakes: an integrated ecological perspective based on a multi-faceted approach, with special focus on shallow lakes

Jeppesen, Erik; Meerhoff, Mariana; Davidson, Thomas A.; Trolle, Dennis; SondergaarD, Martin; Lauridsen, Torben L.; Beklioglu, Meryem; Brucet Balmaña, Sandra; Volta, Pietro; González-Bergonzoni, Iván; Nielsen, Anders (PagePress, 2014)

Freshwater ecosystems and their biodiversity are presently seriously threatened by global development and population growth, leading to increases in nutrient inputs and intensification of eutrophication-induced problems ...
Fish diversity in European lakes: geographical factors dominate over anthropogenic pressures

Brucet Balmaña, Sandra; Pédron, Sthépanie; Mehner, Thomas; Lauridsen, Torben L.; Argillier, Christine; Winfield, Ian J.; Volta, Pietro; Emmrich, Matthias; Hesthagen, Trygve; Holmgren, Kerstin; Benejam Vidal, Lluís; Kelly, Fiona; Krause, Teet; Palm, Anu; Rask, Martti; Jeppesen, Erik (Wiley, 2013)

1. We aimed to distinguish the relative contributions of natural and anthropogenic local factors on patterns of fish diversity in European lakes at different geographical scales. 2. We compiled data from standardised ...
Generation and nonlinear evolution of shore-oblique/transverse sand bars

Garnier, R.; Calvete, D.; Falqués, Albert; Caballeria, Miquel (Cambridge University Press, 2006)

The coupling between topography, waves and currents in the surf zone may selforganize to produce the formation of shore-transverse or shore-oblique sand bars on an otherwise alongshore uniform beach. In the absence of ...
Self-organization mechanisms for the formation on nearshore crescentic and transverse sand bars

Caballeria, Miquel; Coco, G.; Falqués, Albert; Huntley, D.A. (Cambridge University Press, 2002)

The formation and development of transverse and crescentic sand bars in the coastal marine environment has been investigated by means of a nonlinear numerical model based on the shallow-water equations and on a simpli ...
Vertical distribution, feeding and vulnerability to tactile predation in Metridia longa (Copepoda, Calanoida)

Vestheim, H.; Brucet Balmaña, Sandra; Kaartvedt, S. (Taylor & Francis, 2013)

We assessed the vertical distribution and feeding of the calanoid copepod Metridia longa in the Oslofjord, Norway during winter and spring 2006. Adult females of Metridia longa inhabited the whole 200 m deep-water column. ...
