Ecological study of chalk streams. Lambourn project. Interim report October 1977 to April 1979 [PDF]
, 1979 Few detailed studies have been made on the ecology of the chalk streams. A complex community of plants and animals is present and much more information is required to achieve an understanding of the requirements and interactions of all the species. It is

Local ciliate communities associated with aquatic macrophytes [PDF]
, 2014 This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus ...

ESMI: a macrophyte index for assessing the ecological status of lakes
Environmental Monitoring & Assessment, 2014 The paper introduces the Ecological State Macrophyte Index (ESMI), a method compliant with the Water Framework Directive (2000/60/EC) for assessing the ecological status of lakes based on macrophytes.

Global Change Likely to Promote the Expansion of the Quagga Mussel (Dreissena bugensis) in Europe
Journal of Biogeography, EarlyView.ABSTRACT Aim Invasive aquatic species are a pressing concern for environmental managers due to their significant impacts and high eradication costs. The Ponto‐Caspian region is a notable source of aquatic invasive species, with over 40 invaders currently affecting freshwater ecosystems throughout Europe.

Reproductive biology of invasive grass carp (Ctenopharyngodon idella) in two North American systems
Journal of Fish Biology, EarlyView.Abstract Grass carp (Ctenopharyngodon idella) are nonnative, herbivorous freshwater fish that represent an ecological threat in North American waters. However, data are limited on reproductive biology specific to wild populations in midwestern North America, despite recent concern for grass carp establishment within the Great Lakes.

Evaluation of macrophyte control in 38 Florida lakes using triploid grass carp [PDF]
, 2000 Florida’s large number of shallow lakes, warm climate and long growing season have contributed to the development of excessive growths of aquatic macrophytes that have seriously interfered with many water use activities.

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]
, 2014 Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Macrophyte biomass predicts food chain length in shallow lakes
, 2015 Food chain length provides insights into how ecosystems function and respond to global change. A recent synthesis has shown that food chain length is significantly related to both ecosystem productivity and ecosystem size.

FEMS Microbiology Ecology, 2014 Epibiotic bacteria on surfaces of submerged macrophytes play important roles in the ecological processes of shallow lakes. However, their community ecology and dynamics are far from understood in comparison with those of bacterioplankton.

Journal of Fish Biology, EarlyView.Abstract Early life development in fishes is a period of high phenotypic plasticity. Water temperatures during embryogenesis can lead to alterations in growth and metabolic and morphological phenotypic variations. This study aimed to characterize the effects of temperature on the growth and morphology of yellow perch throughout early development, a ...
