How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Clara E. Castaños currently works at the ARC Centre of Excellence in Plant Energy Biology, University of Western Australia. Clara does research in Entomology, Ecology and Evolutionary Biology. Their most recent publication is 'Physiological condition and wing pigmentation expression in a damselfly with seasonal polyphenism: Polyphenism and condition in a damselfly'.

Honey bee nutritional health depends on nectar and pollen, which provide the main source of carbohydrates, proteins and lipids to individual bees. During malnutrition, insect metabolism accesses fat body reserves. However, this process in bees and its repercussions at the colony level are poorly understood. Using untargeted lipidomics and gene expr...
We propose two modifications to enhance the laboratory technique described by Foray and collaborators (2012) “A handbook for uncovering the complete energetic budget in insects: the van Handel’s method (1985) revisited”. Foray´s protocol is a simple and fast method to measure different energetic compound levels in insects, i.e. glycogen, protein, l...
Parental care patterns increase offspring fitness but may drive energetic costs to parents. The costs associated with parental care can change over time, decreasing the condition of parents that experience prolonged parental care. Thus, males can modulate parental effort based in the relative fitness cost/benefit pay-offs under different stages and...
Secondary sexual traits can be indicators of individual condition that may present seasonal polyphenism as a result of the differential costs of expression along the season. Wing spots in male damselflies of the Calopterygidae family are secondary sexual traits associated with intrasexual competition and mate choice. Hetaerina titia Drury is a calo...
