Annales de Limnologie - International Journal of Limnology
Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives.
Journal founded by University Paul Sabatier, Toulouse in 1964.
This work allows us to analyze the changes in invertebrate communities of the Luján River basin in an urbanization gradient and to determine the specific indicator taxa of urbanized habitats.

The aim of the study is to determine the effects of Bentagran on growth and oxidative effects to Chlorella vulgaris and Arthrospira platensis and to evaluate the herbicide toxicity on primary producers of aquatic ecosystems. Bentagran effected to the biomass accumulation and chlorophyll-a content in a dose-dependent manner and it caused the oxidative stress in both organism.

This study adds additional knowledges about the taxonomy of the stonel loach Barbatula spp. Several cryptic evolutionary lineages were previously highlighted by molecular data. Here we revalidate Barbatula hispanica, previously considered a junior synonym of B. quignardi. This species is found in the Ebro drainage and in Cantabria (Spain) as well as in the Adour drainage (Southwestern France). This is important for the conservation and for a region with a high rate of endemicity.

The objective of this study was to identify the presence of morphotypes L. bulla strains from Quintana Roo, México and their life history traits. Our results indicated that L. bulla has two morphotypes: large morphotype and small morphotype. The large presented short life expectancy, intrinsic positive growth, short generational time and low number of descendants, that reach sexual maturation in an accelerated manner, while in the small the opposite occurred. In conclusion, this study indicates the possible coexistence in the same geographical bioregion of two different morphotypes of L. bulla, one is a small-sized distributed in the northwest of Quintana Roo and another large-sized in the southwest.

This study analyzed the population structure and habitat use of the Japanese eel (Anguilla japonica) and the marbled eel (Anguilla marmorata) in the Pearl River based on data collected from 2015 to 2018. A total of 181 Japanese eels and 56 marbled eels were collected, over half of which were middle-sized eels between 255 and 600 mm in length. Although they are sister species, Japanese eels mainly inhabit complex river habitats characterized by high river fractals and coefficients of fluvial facies, while marbled eels mainly inhabit wider and deeper river sections. The results of this study showed that wild Anguilla spp. resources in the Pearl River were extremely low and there was an urgent need for conservation and management of eel resources in south China.
