#Agencies should use common approach to evaluate risks pesticides pose to endangered specieswhen determining the potential effects pesticides could pose to endangered
or threatened species the U s. Environmental protection agency National Marine Fisheries Service (NMFS) and Fish and Wildlife Service (FWS) should use a common scientific approach says a new report from the National Research
Specifically the agencies should use a risk assessment approach that addresses problem formulation exposure analysis effects analysis and risk characterization.
or methods for determining the risks pesticides pose to listed species and their habitats. EPA FWS and NMFS have developed their own approaches
Although the agencies have tried to resolve their differences in assessment approaches they have been unsuccessful at reaching a consensus. As a result the National Research Council was asked to examine the scientific and technical issues related to determining risks posed by pesticides to listed species. The committee
The risk assessment paradigm that traces its origins to the Research Council reports Risk Assessment in the Federal government:
Advancing Risk Assessment has become scientifically credible transparent and consistent; is anticipated reliably by all parties involved in decisions regarding pesticide use;
Such a process is used broadly for human-health and ecological risk assessments throughout the federal government.
which it views as necessary to ensure a complete and representative assessment of risk and that each agency's technical needs are met.
The committee examined several components of the risk assessment process where better coordination and agreement would facilitate an integrated approach to examining risks to listed species and their habitats.
These included evaluating methods for identifying the best scientific data available assessing approaches for developing modeling assumptions identifying geospatial information that might be used in the risk assessment reviewing approaches for characterizing effects analyzing the scientific information available for estimating effects of mixtures
and inert ingredients and examining the use of uncertainty factors to account for gaps in data.

#Power struggles are kept best out of the public eye: Audiences influence future status of quails following fights between rivalsfor animals prevailing in a fight affects their likelihood of winning future conflicts.
The opposite is true of losing a fight. The sex hormone testosterone is believed often to mediate this winner effect.
Researchers from the Max Planck Institute for Ornithology in Seewiesen have examined whether the presence of an audience influences the behaviour and the testosterone changes of Japanese quails (Coturnix japonica) after a fight.
The evidence shows that both winners and losers exhibit raised testosterone levels after a conflict without an audience.
Furthermore both winners and losers are able to maintain their social status within their group. With an audience on the other hand this remained true for winners
Battles for territory and mating partners are widespread in the animal world and are fought usually by males.
The concentration of this substance often rises dramatically during a fight. However the social environment in which the rivals fight their battle can change the context
and affect the role of testosterone for maintaining dominance. Experience plays a role for instance how often the opponents got involved in a conflict
and whether they have met before. Of crucial importance can also be whether the fight is watched by spectators.
Audiences can have a decisive effect on the outcome of a contest between humans too.
With support of the Alexander-Von-humboldt Society scientists working with Katharina Hirschenhauser from the Max Planck Institute for Ornithology in Seewiesen have been studying the influence of mixed-sex audiences on future social status after a fight.
The scientists observed fights between two dominant male quails in a central arena. The members of the respective social group either were allowed to watch the fight or not.
During the fighting phase which lasted an average of seven minutes the eventual winners attacked their rivals 29 times on average.
Although the fights are naturally pretty rough none of the combatants got seriously injured. The winners without exception retained their dominant status (the winner effect.
however even the losers were able to maintain their dominant status. As expected testosterone levels were raised after the fight
After a fight in front of an audience though the losers had lower testosterone levels. The winners on the other hand showed a similar increase to quails that had fought without an audience.
In order to determine whether a change in status after losing a fight in front of an audience could be prevented physiologically the scientists treated the losers immediately after the fight with a testosterone cream on the skin.
They injected the winners with a testosterone blocker directly after the fight and observed their behaviour in the social group.
Apparently the information about a fight essentially determines the loser's future status in its group.
Next the scientists would like to test the direction of information use in other words how the combatants behave
but the observers are informed fully about the fight's outcome. Story Source: The above story is provided based on materials by Max Planck Institute for Ornithology.

Green crabs won the struggle for the burrows. In fact sesarma crabs survived the tussle only 15 percent of the time.

The other is that ecologists should account for the power of a predator's threat not just its actual attacks.
