We believe it important that the hen harrier recovery plan includes this practical trial of a well understood raptor conservation tool, the brood
On the initial day of an experiment, adult populations were examined and the requisite number of females with brood
tubes were set aside.
Number of worker cells per unit area: The average numbers of worker cells per unit area were determined as the number of worker brood
cells/dm2 in built combs.
The Varroa control was done and experimental colonies were equalized with regard to adult bee, brood
and food stocks (Mahmood et al.
Selection for honey production was performed by evaluation of morphometric characteristics and emergence weight of queens and hygienic behavior by assessing the removal of dead brood
within 24h by worker honeybees in colonies daughters of mother queens (Costa-Maia et al.
Therefore, control for any confounding temporal effect upon EPP we randomly assigned boxes to treatments, so approximately half of the pairs were supplemented during the fertile period of their second brood
but not of their third, while the other half were supplemented during the fertile period of their third brood
but not of their second.
Well fed fire ant laboratory colonies do not normally stop producing brood
as long as temperatures remain at or above 25[degrees]C and below 32[degrees]C (Porter 1988), unless the colonies are diseased or seriously stressed in some way.
ECHO reader Danielle Stages, who tweeted @ LivEchonews the lovely picture of the cute brood
, said she noticed the swans and their offspring as she was out walking in her local park.
5% of pairs in a study in Germany (Buchmann, 2001), but normally raise only one brood
in Iceland and Scandinavia (Cramp, 1998; Conder, 1989).
We thus sought to examine whether this change variable was related to change over the non-breeding period (as the log-transformed ratio of spring numbers in year t + 1 to post-breeding numbers in year t), change over the breeding period (as the log-transformed ratio of post-breeding adult numbers in year t to spring numbers in year t) and grouse productivity, measured in three ways: proportion of hens with broods
, mean young/brood
and young to adult ratio.
XI, last seen on a dairy farm in 1954, is assumed to be mostly extinct; Brood
VII, which consists of just a single species (most broods
are a mingling of three different kinds of cicada) is limited to just the Onondaga Nation in upstate New York.
Alison who's just finished playing a downtrodden mum to another thankless brood
in The Syndicate, might well be thinking much the same thing.
