TRACE ELEMENTS IN THE AQUATIC ECOSYSTEMS OF THE AMUR RIVER
The microelement composition of the water-bottom sediments-macrophytes-macrophytes-macrofauna system was considered р. Cupid. Installed minimal and the maximum concentrations of trace elements in of its individual components. It is shown that the content

ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Oligochaeta (Annelida: Clitellata) associated to aquatic macrophytes in Brazil
Oligochaeta are still characterized as a poorly studied group among the aquatic macroinvertebrates and few studies about their ecology were conducted in Brazil.

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Effects of ultraviolet radiation on pigmentation and malondialdehyde content of three aquatic macrophytes [PDF]
A study has been done in order to evaluate the ill effects of UV-A,UV-B and UV-C on pigmentation and malondialdehyde content of floating macrophytes (Lemna sp., Pistia sp. and Eichhornia sp.) in one, three, and five days interval.

Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

Seagrass flowering underpins seed‐based restoration and is governed by the interaction of multiple abiotic and biotic drivers operating across a range of temporal and spatial scales. In New Zealand/Aotearoa, flowering was historically considered rare, but emerging evidence indicates it is more widespread than previously recognised, creating new ...

ABSTRACT Natural inland wetlands in Southeast Asia provide key biodiversity, hydrological, carbon‐storage and livelihood functions, but are increasingly affected by land‐use change, fire, hydrological modification and climate change and variability.

The evolutionary origins of streptophyte multicellularity
The phylogeny of streptophytes and the deep origin of branching filamentous growth. Summary Over their more than 1 billion years of evolutionary history, streptophytes have repeatedly transitioned between unicellular, simple multicellular and complex multicellular forms.

ABSTRACT There is growing interest in the co‐culture of macroalgae and filter‐feeding bivalves due to anticipated trophic benefits that may enhance the productivity of both organisms. Detritus from cultured macroalgae has the potential to supplement bivalve diets, yet few studies have directly examined this relationship in co‐culture systems.
