Determination of toxicity assays, trophic state index, and physicochemical parameters on Piracicaba River and Itapeva Stream

, 2015
Anthropogenic activity has a great impact on aquatic environments, causing changes in biodiversity and the environment. In an attempt to determine pollution levels, we established physicochemical parameters, a trophic state index and toxicity assays. The

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

The potential for inferring trophic state of Lake Wairarapa using zooplankton community composition

, 2006
The use of biotic responses to infer lake trophic state (i.e., the bioindicator approach) is commonly neglected in favour of chemical and physical methods. Duggan et al.

Trophic state index reveals hypereutrophic nature of a subtropical urban lake

Brazilian Journal of Aquatic Science and Technology
Abstract As a consequence of the growth of large urban centers close to aquatic environments, the input of nutrients from specific or diffuse sources of contamination has significantly impacted the water quality of these water resources. One of the main impacts on these ecosystems is eutrophication, which occurs due to the excessive nutrient load ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Water quality of the São Gonçalo channel, urban and agricultural water supply in southern Brazil

RBRH
São Gonçalo channel connects Patos and Mirim lagoons, in South Brazil. This ecosystem is 70 Km long, and is a major regional source of urban and agricultural water supply, mainly for the municipality of Rio Grande, with ca. 250 thousand citizens.

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Effect of zebra mussels (Dreissena polymorpha) on trophic state in northern Michigan lakes [PDF]

, 2007
Undergraduate Research Exper.Invasive species cause massive damage to the environment, human health, and the economy. Zebra mussels (Dreissena polymorpha) first invaded North America in 1988 and have had dramatic effects on many lake ecosystems. They are
