What happens to size, metabolic rate and population growth when cultured with and without competitors? Research by @giulia_ghedini and @djm_MEEG in @CurrentBiology is summarised here: cgb.org.au/2023/08/15/can-co…
Congratulations to Lesley Alton for winning the Mike Cullen Research Fellow Award. Lesley summarised her research on animal responses to stressor interactions in the Mike Cullen lecture and you can read about it here: cgb.org.au/2023/09/15/mike-c…

Copepods cultured in high-food environments differed in life-history traits from those cultured in low-food environments. Alex Blake and Tim Coulson found these discrepancies didn’t translate to differences at the population level. @GeometricBiol cgb.org.au/2023/08/17/from-l… @Oikos
Experimental evolution of copepods in different food regimes evoked evolutionary changes in body size, the relationship between size and reproductive output and offspring investment strategies cgb.org.au/2023/08/14/how-wi… @djm_MEEG @EvolAppJournal

How has live birth evolved when there are thermal mismatches between mothers and their offspring?
Our new paper @EvolLetters explores the role of behavioural plasticity in facilitating shifts in reproductive mode 🐍🦎

Does variation in nest temperature have long-term effects on the phenotypes of ectotherms? Madeleine de Jong and colleagues found, yes it does, using a model lizard species, the delicate skink, Lampropholis delicata. royalsocietypublishing.org/d… @Craig_R_White @BBM_Wong @lesley_alton

Our new paper testing potential mechanisms of local adaptation to cool climates in the excellent wall lizard study system!
A great collaborative effort of field sampling in Italy, metabolism measures in Sweden, and yolk hormone analysis in Finland 🦎 1/5
Now out in @AnimalEcology led by @amandakpet: #lizard embryos from high altitude develop faster without increasing metabolic rate, and they allocate more #energy towards growing tissue, compared to low-altitude embryos. Powered by our friends @SableSys

@jackTOrford et al found exposure to environmentally realistic concentrations of the agricultural pollutant 17β-trenbolone altered morphology and behaviour in southern brown tree frog tadpoles. @BBM_Wong @lesley_alton @HungTan_ @r_tingley @MArtin_J_M_34 sciencedirect.com/science/ar…

Are you a whole organism biologist with a masters or honours degree? We need help undertaking data mining activities using standard systematic literature review protocols, data extraction and compilation of databases. This is a 3-month casual contract careers.pageuppeople.com/513…

Does the colour polymorphisms of the delicate skink have an adaptive relationship with lizard body temperature? @Genevieve_DM @chapple_lab @Craig_R_White @FarquharJules suggest, however, that behaviour is actually the key
to mediating thermoregulation. sciencedirect.com/science/ar…
How do size and other traits differ between 'dispersers' and 'non dispersers'? @pieter_arnold @Craig_R_White @InvasionEcology investigated the responses of dispersal and morphological traits to spatial sorting in red flour beetles zslpublications.onlinelibrar…

What happens if you manipulate the major nutritional determinant of lifespan (sterols) independently of the major nutritional determinant of egg production? @BrookeZanco et al found mothers live longer and lay more eggs on high sterol diets. reader.elsevier.com/reader/s… @mattpiperlab

Can removing an essential amino acid from the diet protect flies against future toxin stress? @TahliaFulton @ChristenMirth and @mattpiperlab found short-term exposure to individual amino acid dropout diets could protect flies against exposure to nicotine royalsocietypublishing.org/d…
Reproductive databases allow us to compare reproductive effort across a whole range of species. Or do they?

What is the optimal size for transition from one life history stage to another? Emily Richardson @Craig_R_White and @djm_MEEG examine existing data to ask if there is a cost/benefit to transition and how this affects optimal size to change cgb.org.au/2022/06/24/when-i… @FunEcology

Water quality entering the waters of the Great Barrier Reef continues to be of urgent concern for policy makers. Best practice suggests land regulation should be risk-based, responsive, & cognisant of the regulated industry’s attitudinal settings. sciencedirect.com/science/ar… @bode_e
