The ecological significance of extremely large flocks of birds
Ecology and Evolution, 2019 Population size is generally limited by resource availability during and outside the breeding season. Therefore, maximum size of flocks may provide important information on population regulation and the influence of diet and trophic level on maximal ...

The trophic evolution of Lake Iseo as related to its holomixis
Journal of Limnology, 1999 Lake Iseo is undergoing a progressive deterioration in water quality, mainly due to eutrophication. This paper, based on measurements performed on the main tributaries and the outflow, considers the phosphorus, nitrogen and silica budget of the lake ...

Ecosphere, 2016 Given current levels of biodiversity loss and environmental change, studies of how food webs respond to disturbance should broaden their focus beyond short‐term disturbances to explore the effects of long‐term, “press” disturbances.

Trophic levels of fish species of commercial importance in the Colombian Caribbean
Revista de Biología Tropical, 2011 Ecological studies on commercial important fish species are of great value to support resource management issues. This study calculated trophic levels of those Colombian Caribbean fish species whose diet has been locally described.

Nitrogen isotope composition of amino acids reveals trophic partitioning in two sympatric amphipods
Ecology and Evolution, 2020 According to ecological theory, two species cannot occupy the same niche. Using nitrogen isotope analyses (δ15N) of amino acids, we tested the extent to which two sympatric deposit‐feeding amphipods, Monoporeia affinis and Pontoporeia femorata, partition

Overfishing and the replacement of demersal finfish by shellfish: an example from the English Channel. [PDF]
PLoS ONE, 2014 The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure of marine ecosystems.
