Corvids are exceptional predators which can become problematic and difficult to manage due to their adaptability, intelligence, and abundance. On Phillip Island (Victoria, Australia) little ravens (Corvus mellori) prey on the eggs of burrow-nesting little penguins (Eudyptula minor) at an ecologically and economically significant colony. Raven depre...
Within some socially monogamous species, the relative contribution of care provided by each parent varies substantially, from uniparental to equitable biparental care. The provision of care is influenced by its costs and benefits, which may differ between parents (leading to inter-parental “conflict”) and are expected to change in relation to the n...
Capsule: Trail cameras monitoring clutches of ground-nesting birds in Australia revealed survival rates and new causes of egg loss. We also show that nests with artificial eggs versus real eggs do not reveal the same information on predators. Aims: We describe the application of trail cameras for monitoring real and artificial clutches of ground-ne...
The authors describe a case of reversed position of the sexes by copulating Red-capped Plovers Charadrius ruficapillus at an intensively studied population at Cheetham Wetlands, Point Cooke Coastal Park, Victoria, Australia (37°53’56”S, 144°47’33”E). http://www.waderstudygroup.org/article/7365/
Predator exclosures (‘nest cages’) around nests are increasingly used to enhance hatching success of declining ground-nesting birds. However, such exclosures are contentious and have been suggested to have detrimental effects on the species which they aim to protect. This study examines whether exclosures increase physiological stress of incubating...
Context Loss of eggs to predators is a major cause of reproductive failure among birds. It is especially pronounced among ground-nesting birds because their eggs are accessible to a wide range of predators. Few studies document the main causes of clutch fate of ground-nesting birds. Aims The main objective of the present study was to identify the m...
Some ground-nesting birds adopt a mixed strategy of nesting in the open, or under cover (e.g. vegetation). This may represent a trade-off between thermally favourable nest sites (covered) and those that enable the early detection and avoidance of predators (open). This study examined whether such a trade-off exists for Red-capped Plover Charadrius...
The Masked Lapwing Vanellus miles is a common ground-nesting shorebird inhabiting grasslands, paddocks, rivers, lakes, swamps and, tidal mud flats. It is particularly common in the urban areas of Phillip Island, Victoria (Dann 1981, Marchant and Higgins 1993). The Masked Lapwing usually lays between one and four eggs (the mean number of eggs per cl...
Hi all, I'm needing to freeze dry and separate egg layers (e.g. chicken egg with yolk, albumen, and shell) and was wondering if there are any resources out there with specific procedural steps? The contents are to be separated for stable isotope analysis. I've come across literature saying freeze-drying and separation of the egg layers has been undertaken in the study but not much as to specific methods that were used (e.g. freeze dry whole egg, then separate, etc).
Any help much appreciated, thanks in advance!
Basically the above. I'll place the foil over the PCR plate, and then run my fingers along all well edges, being quite thorough with it all. Immediately after PCR the samples look good and there may be little loss, but after several days in fridge storage I've found entire samples have disappeared since. The samples affected are typically in the wells along the edges of the plate; I've rarely lost samples from the centre of the plate.
Looking to move to cap lids, but thought I'd ask here in case anyone who has experienced this has recommendations.
Thanks in advance.
UPDATE 4/12/17: Have purchased both cap lids and plastic paddle to trial both methods; will see how we go!
