Ecological study of chalk streams. Lambourn project. Interim report October 1977 to April 1979 [PDF]

open access: yes, 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

Effects of aquatic vegetation type on denitrification [PDF]

open access: yes
In a microcosm 15N enrichment experiment we tested the effect of floating vegetation (Lemna sp.) and submerged vegetation (Elodea nuttallii) on denitrification rates, and compared it to systems without macrophytes.

Quantifying leaf herbivory: A guide to methodological trade‐offs and best practices

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Leaf herbivory is a ubiquitous ecological interaction that varies significantly in intensity across species, habitats, and biogeographic regions. Although quantification of leaf damage is crucial for understanding many ecological processes, the accuracy and precision of various damage estimation methods used by researchers, including visual ...

Effects of salinization on tropical freshwater wetland primary producers and aquatic invertebrates

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Sea level rise is expected to transform coastal aquatic ecosystems world‐wide. The freshwater wetlands of tropical northern Australia are among the most biodiverse and productive ecosystems on the continent, but owing to high regional rates of sea level rise coupled with low‐lying land and large tides they are increasingly affected by saltwater ...

Nutritional effects on the expression of cryptic pigmentation in freshwater isopods

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Cryptic pigmentation is a key phenotypic adaptation that helps many benthic invertebrates evade visual predators. However, little is known about whether and how the expression of pigmentation phenotypes that match the habitat background is influenced by the availability of nutritional resources.

Morphometry and retention time as forcing functions to establishment and maintenance of aquatic macrophytes in a tropical reservoir

open access: yesBrazilian Journal of Biology
Macrophytes may constitute an important resource for several chemical, physical and biological processes within aquatic ecosystems. This study considers that in tropical reservoirs with low retention time and with low values of shoreline development (DL),
