Larval nutrition impacts survival to adulthood, body size, and the allometric scaling of metabolic rate in adult honeybees
<p>Resting metabolic rate (RMR) is a fundamental physiological measure linked to numerous aspects of organismal function, including lifespan. Although dietary restriction in insects during larval growth/development affects adult RMR, the impact of larval diet <i>quality</i> on adult RMR has not been studied. Using <i>in vitro</i> rearing to control larval diet quality, we determined the effect of dietary protein and carbohydrate on honeybee survival-to-adulthood, time-to-eclosion, body mass/size and adult RMR. High carbohydrate larval diets increased survival-to-adulthood and time-to-eclosion compared to both low carbohydrate and high protein diets. Upon emergence, bees reared on the high protein diet were smaller and lighter than those reared on other diets, whilst those raised on the high carbohydrate diet varied more in body mass. Newly emerged adult bees' reared on the high carbohydrate diet showed a significantly steeper increase in allometric scaling of RMR compared to those reared on other diets. This suggests that diet quality influences survival-to-adulthood, time-to-eclosion, and the allometric scaling of RMR. Given that agricultural intensification and increasing urbanisation have led to a decrease in both forage availability and dietary diversity for bees, our results are critical to improving understanding of the impacts of poor developmental nutrition on bee growth/development and physiology.</p>

Approximately 300 mm across. b. Crushed individual showing oysters encrusting both flanks of the conch. 250 mm in diameter. c. Wave-worn conch showing oysters attached to the umbilicus, the venter and possibly the inside of the body-chamber. Tape measure for scale. d. Flank of conch with crinoid debris and oysters spread around its periphery. Scope of image approximately 350 mm. in 'Cenoceras Islands' In The Blue Lias Formation (Lower Jurassic) Of West Somerset, Uk: Nautilid Dominance And Influence On Benthic Faunas

Text-fig. 9. a. Shorn-off, vertically embedded conch surrounded by layer of crinoid debris at level of planation of shell and with some debris within the conch at this level. Lateral width of body-chamber 80 mm. b. Example of ammonite that occurs rarely in the Main Cenoceras Bed. Note the poorly defined shell particularly on the outer whorl, suggesting partial dissolution.

Lusitanispermum choffatii gen. et sp. nov. seeds from the Early Cretaceous Famalicão locality (sample 025), Portugal; Synchrotron radiation X-ray tomographic microscopy (SRXTM, orthoslices). a) Longitudinal orthoslice (yz0769) through the median plane of the seed (S174345) showing expanded exotestal cells (ex, arrow head) in the hilar region and well-preserved cellular nutritive tissue with an embedded tiny embryo (asterisk markes the margin of the embryo); note well-developed mesotesta (me) on the raphal side of seed. b) Longitudinal orthoslice (yz0750) in the median plane showing detail of micropylar part of seed with well-preserved exotesta (ex) and mesotesta (me) and tiny embryo with two rudimentary cotyledons (asterisks mark the margin of the cotyledons); note numerous granular bodies in the cellular nutritive tissue that are probably the remains of protein and lipid bodies. c) Transverse orthoslice (xy0311) through seed below hilum showing the bulging exotesta (arrow heads) (S174472); note that the exotestal cells in this region have thinner walls (arrows). d) Transverse orthoslice (xy0900) through the middle of a seed showing the uneven thickening of the anticlinal walls of the exotestal cells (ex), which are thicker towards the outside and very thin towards the inside; note also mesotesta (me) and the well-preserved cellular nutritive tissue (S174472). Scale bars = 500 µm (a, d); 250 µm (b, c). in Extinct Taxa Of Exotestal Seeds Close To Austrobaileyales And Nymphaeales From The Early Cretaceous Of Portugal
