Rapid niche expansion by selection on functional genomic variation after ecosystem recovery
It is well recognized that environmental degradation caused by human activities can result in dramatic losses of species and diversity. However, comparatively little is known about the ability of biodiversity ...

Cross-realm assessment of climate change impacts on species’ abundance trends
Climate change, land-use change, pollution and exploitation are among the main drivers of species’ population trends; however, their relative importance is much debated. We used a unique collection of over 1,0...

Impacts of climate warming on the long-term dynamics of key fish species in 24 European lakes
Fish play a key role in the trophic dynamics of lakes. With climate warming, complex changes in fish assemblage structure may be expected owing to direct effects of temperature and indirect effects operating t...

Spatio-temporal variation of the zooplankton community in a tropical caldera lake with intensive aquaculture (Lake Taal, Philippines)
Zooplankton were collected from Lake Taal between January and December 2008 in order to test for differences in species composition and abundance between a lake basin with intensive fish cage (FC) aquaculture ...

A mesocosm experiment investigating the effects of substratum quality and wave exposure on the survival of fish eggs
In a mesocosm experiment, the attachment of bream (Abramis brama) eggs to spawning substrata with and without periphytic biofilm coverage and their subsequent survival with and without low-intensity wave exposure...

Lake water level increase during spring affects the breeding success of bream Abramis brama (L.)
In Lake Constance, Eurasian bream Abramis brama (L.) spawn in very shallow littoral areas by the beginning of May. They attach their adhesive eggs to pebble and cobble substratum at <40 cm depth. Increasing water...

Influence of climate variability on whitefish (Coregonus lavaretus) year-class strength in a deep, warm monomictic lake
The year-class strength (YCS) of Blaufelchen (Coregonus lavaretus) in deep Upper Lake Constance was analysed for a 52-year period, from 1947 to 1998. Despite strong anthropogenic influences on the species’ popula...

Kin and population recognition in sympatric Lake Constance perch (Perca fluviatilis L.): can assortative shoaling drive population divergence?
Prior studies have shown that perch (Perca fluviatilis L.) of Lake Constance belong to two genetically different but sympatric populations and that local aggregations of juveniles and adults contain closely relat...

Distribution of perch (Perca fluviatilis L.) during their first year of life in Lake Constance
The distribution and behaviour of larval and juvenile perch (Perca fluviatilis L.) were studied for two years in large, deep Lake Constance. After hatching larvae were transported by water currents to the open wa...

Limits for the detection of daily otolith increments in whitefish (Coregonus lavaretus L.) larvae
The formation of daily otolith increments in European lake white-fish was evaluated in the laboratory during 40 days at 4, 6, and 8 °C under limited and ad libitum food supply. Daily increments were easily identi...

Daily increments on the otoliths of larval and juvenile Coregonus spp., and their modification by environmental factors
The sagittal otoliths of pre- and posthatch embryos, larval, and juvenile coregonids (Coregonus spp.) were examined for growth increments. Under laboratory conditions, a check is formed on the day of hatching and...
