Molecular traces of alternative social organization in a termite genome.
TLDR
The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation. Expand
Costs of immunity in insects: an induced immune response increases metabolic rate and decreases antimicrobial activity
TLDR
The results support the growing evidence that immune responses entail specific energetic and corresponding physiological costs, and are in line with life-history theory. Expand
Standard methods for physiology and biochemistry research in Apis mellifera
TLDR
Sensitive techniques for the quantification of juvenile hormone levels circulating in haemolymph, as well as its synthesis by the corpora aliata are described and a standard method for the detection and analysis of certain biogenic amines of interest is presented. Expand
Gustatory Perception and Fat Body Energy Metabolism Are Jointly Affected by Vitellogenin and Juvenile Hormone in Honey Bees
TLDR
This study demonstrates that the Vg–JH regulatory module controls changes in carbohydrate metabolism, but not lipid metabolism, when worker bees shift from nursing to foraging, and proposes that honey bees have conserved pathways in carbohydrates metabolism and conserved connections between energy metabolism and gustatory perception. Expand
Endocrine changes in maturing primary queens of Zootermopsis angusticollis.
TLDR
The hypothesis that JH plays a dual role in termite queens depending on their stage of development is supported; an elevated JH titer in immature alates may maintain reproductive inhibition, but an elevated Titer in mature queens may stimulate ovarian activity. Expand
Worker division of labor and endocrine physiology are associated in the harvester ant, Pogonomyrmex californicus
TLDR
Data from this study are consistent with the reproductive ground plan hypothesis (RGPH), which posits that the reproductive regulatory mechanisms of solitary ancestors were co-opted to regulate worker behavior. Expand
Exaggerated trait growth in insects.
TLDR
It is suggested that distinct developmental mechanisms underlie the evolution of the different types of exaggerated traits, and explicit predictions for the types of regulatory pathways likely to underlie each type of exaggerated trait are made. Expand
Maternal Effect on Female Caste Determination in a Social Insect
TLDR
Data demonstrate that the developmental fate of female brood is strongly influenced by maternal effects in ants of the genus Pogonomyrmex, suggesting that the trigger for caste differentiation may be independent of the quantity and quality of resources provided to larvae. Expand
The role of reduced oxygen in the developmental physiology of growth and metamorphosis initiation in Drosophila melanogaster
TLDR
It is shown that oxygen level is one of multiple cues that together regulate adult size and the timing and dynamics of growth, developmental rate and ecdysone signaling. Expand
Neurohormonal changes associated with ritualized combat and the formation of a reproductive hierarchy in the ant Harpegnathos saltator
TLDR
Support is provided that biogenic amines link changes in behavior and dominance with reproductive activity in H. saltator as well as drive differences in worker task performance. Expand
