IBIS - highlights from latest issue 
Volume 155  |  Issue 1  |  January 2013

The January issue of Ibis contains papers on a wide range of subjects from fossil parrots to the uses of the latest thermal technology in ornithology.

All papers in the January issue are free to view!

 

Our featured paper this month is a fascinating demonstration of the impacts that even naturally occurring predators can have on naive prey populations (Predator-avoidance behaviour in a nocturnal petrel exposed to a novel predator. Ibis 155: 16-31). Will Miles and colleagues show that while Leach’s Storm-petrels nesting on St Kilda show the characteristic predator avoidance strategy of noctural colony attendance, there was no evidence that they have evolved any specific avoidance of newly colonised Great Skuas, which kill them in large numbers each year. As Ian L. Jones points out in his accompanying Commentary article (Evolutionary lag of predator avoidance by island seabirds, and what happens when naturally occurring colonists become 'invasive'), the results cause us to rethink our definition of what constitutes an 'invasive' species.

 

Other papers in this issue include: 

  • A review on the uses of thermal imaging in the study of birds, describing the latest technology and suggesting how the science of thermography can help further in the study of birds | View paper
  • An assessment of methods used to quantify the statistical power of detecting changes in numbers of seabirds counted during at-sea transects, with suggestions for improving counts in the future | View abstract
  • A study of the relationship between nesting habitat and nest concealment in the rate of parasitism of songbirds by Cuckoos | View abstract
  • An extraordinary study of the relationship between colour morph and the timing of breeding and offspring number of Gyrfalcons in Greenland, showing that pure white birds and grey birds differ significantly in their breeding performance | View abstract
  • A description of two new species of parrot from the early Pliocene, the earliest geological record of parrots in Africa, from a region of South Africa where no parrots currently occur | View abstract

AVIAN DEMOGRAPHY IN A CHANGING WORLD

BOU 2013 ANNUAL CONFERENCE
26 - 28 MARCH 2013
Leicester, UK


We are living through a period of major environmental change at both local and global scales. Many species are declining sufficiently rapidly to be of serious conservation concern, yet others are proliferating, some to the point of being invasive. These rapid changes are being replicated in most of the globe’s avifaunas. Developing effective responses to these spatio-temporal changes requires scientists and policy makers to recognise the need not just to monitor them, but to understand the demographic mechanisms underpinning them. Critically, it is essential that our predictive capacity is improved by developing tools that enable the demographic consequences of potential management action to be quantified. 

Early bird rates available to 14 February!

# How useful are species?
That biodiversity is valuable and worth conserving is something about which most people with an interest in the environment can agree. But what is “biodiversity”?
