Oligochaeta (Annelida, Clitellata) in the Aquatic Macrophytes in Dam of Ribeirão of Anhumas Screamers (Américo Brasiliense-Sp)

Revista Brasileira Multidisciplinar - ReBraM /Brazilian Multidisciplinay Journal, 2014
Macrophytes have different morphological structural complexities, offering to animals the availability of various niches. These plants are also an important substrate for the development of periphyton, which has a high nutritional value and is one of the

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

River Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

River Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Nutrients and warm temperatures explain a seasonal cycle of colonization and ecosystem collapse in a floodplain pond

Ecosphere
Resilient ecosystems maintain similar species diversity and composition despite extreme environmental variation, while ecosystem collapse can be characterized by high mortality rates and decreased species diversity.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

Environmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Growth rate, protein:RNA ratio and stoichiometric homeostasis of submerged macrophytes under eutrophication stress

Knowledge and Management of Aquatic Ecosystems, 2016
Growth rate hypothesis (GRH) and stoichiometric homeostasis of photoautotrophs have always been questioned. However, little is known about GRH and stoichiometric homeostasis of aquatic plants, especially submerged macrophytes ...

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

The study of aquatic macrophytes in Neotropics: a scientometrical view of the main trends and gaps

Brazilian Journal of Biology
Aquatic macrophytes comprises a diverse group of organisms including angiosperms, ferns, mosses, liverworts and some macroalgae that occur in seasonally or permanently wet environments.

Presence and abundance of macrophytes in Lake Slivniško jezero

Acta Biologica Slovenica, 2015
Macrophytes are an important part of the lake biota. They are also bioindicators of environmental conditions. The goal of the present research was to determine species richness and abundance as well as longitudinal and depth distribution of macrophytes ...

On traits matching and the modular organization of food web and occurrence networks

Journal of Animal Ecology, EarlyView.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...
