Viability of subitaneous eggs of the copepod, Acartia tonsa (Dana), following exposure to various cryoprotectants and hypersaline water [PDF]
, 2009 Subitaneous eggs were obtained from monocultures of the calanoid copepod Acartia tonsa (Dana), Gulf of Mexico strain. Eggs were exposed to methanol, ethylene glycol, propylene glycol, glycerine, and DMSO at 0.0, 0.1, 0.5, 1.0, 2.0, and 5.0 M and ...

River Research and Applications, EarlyView.ABSTRACT The pattern of flow or hydrological connection between a river's main channel and its floodplain can vary seasonally and spatially in frequency, duration, direction, and magnitude. Such variation is expected to promote habitat and biotic diversity.

Effects of different types of fertilizers on plankton productivity in earthen ponds [PDF]
, 2003 Three fertilizer types (NPK, Super-phosphate and cow dung) were applied at two levels (Low, 0.3 kg/25m super(2)/2weeks and High, 0.7kg/25 m super(2)/2weeks) to 12 ponds with two ponds serving as control.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach
Environmental Toxicology, EarlyView.ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models
Environmental Toxicology, EarlyView.ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Colder rotifers grow larger but only in oxygenated waters
, 2015 Why do colder ectotherms grow more slowly but mature at a larger size? Some researchers have argued that oxygen supply and demand play a crucial role in these processes, but many studies conflated the effects of oxygen and temperature.

An evolutionary perspective on the response‐effect framework
Functional Ecology, EarlyView.Abstract The response‐effect framework (REF) has provided a foundational approach in functional ecology, using traits to predict how species respond to environmental factors (‘response traits’) and influence ecosystem functioning (‘effect traits’).
