4Viability,behavior,and color expression in the offspring of matings between common wall lizard Podarcis muralis color morphs显示文摘Color polymorphisms are widely studied to identify the mechanisms responsible for the origin and maintenance of phenotypic variability in nature.Two of the mechanisms of balancing selection currently thought to explain the long-term persistence of polymorphisms are the evolution of alternative phenotypic optima through correlational selection on suites of traits including color and heterosis.Both of these mechanisms can generate differences in offspring viability and fitness arising from different morph combinations.Here,we examined the effect of parental morph combination on fertilization success,embryonic viability,newborn quality,antipredator,and foraging behavior,as well as inter-annual survival by conducting controlled matings in a polymorphic lacertid Podarcis muralis,where color morphs are frequently assumed to reflect alternative phenotypic optima(e.g.,alternative reproductive strategies).Juveniles were kept in outdoor tubs for a year in order to study inter-annual growth,survival,and morph inheritance.In agreement with a previous genome-wide association analysis,morph frequencies in the year-old juveniles matched the frequencies expected if orange and yellow expressions depended on recessive homozygosity at 2 separate loci.Our findings also agree with previous literature reporting higher reproductive output of heavy females and the higher overall viability of heavy newborn lizards,but we found no evidence for the existence of alternative breeding investment strategies in female morphs,or morphcombination effects on offspring viability and behavior.We conclude that inter-morph breeding remains entirely viable and genetic incompatibilities are of little significance for the maintenance of discrete color morphs in P.muralis from the Pyrenees.Javier ABALOS Guillem PEREZ I DE LANUZA Alicia BARTOLOME Fabien AUBRET Tobias ULLER Enrique FONT 2022Current Zoology2022,68,1:0
5High-elevation hypoxia impacts perinatal physiology and performance in a potential montane colonizer显示文摘Climate change is generating range shifts in many organisms,notably along the elevational gradient in mountainous environments.However,moving up in elevation exposes organisms to lower oxygen availability,which may reduce the successful reproduction and development of oviparous organisms.To test this possibility in an upwardcolonizing species,we artificially incubated developing embryos of the viperine snake(Natrix maura)using a split-clutch design,in conditions of extreme high elevation(hypoxia at 2877 m above sea level;72%sea-level equivalent O2 availability)or low elevation(control group;i.e.normoxia at 436 m above sea level).Hatching success did not differ between the two treatments.Embryos developing at extreme high elevation had higher heart rates and hatched earlier,resulting in hatchlings that were smaller in body size and slower swimmers compared to their siblings incubated at lower elevation.Furthermore,post-hatching reciprocal transplant of juveniles showed that snakes which developed at extreme high elevation,when transferred back to low elevation,did not recover full performance compared to their siblings from the low elevation incubation treatment.These results suggest that incubation at extreme high elevation,including the effects of hypoxia,will not prevent oviparous ectotherms from producing viable young,but may pose significant physiological challenges on developing offspring in ovo.These early-life performance limitations imposed by extreme high elevation could have negative consequences on adult phenotypes,including on fitness-related traits.Jérémie SOUCHET Eric J.GANGLOFF Gaëlle MICHELI Coralie BOSSU Audrey TROCHET Romain BERTRAND Jean CLOBERT Olivier CALVEZ Albert MARTINEZ-SILVESTRE Elodie DARNET Hugo LE CHEVALIER Olivier GUILLAUME Marc MOSSOLL-TORRES Laurent BARTHE Gilles POTTIER HervéPHILIPPE Fabien AUBRET 2020Integrative Zoology2020,15,6:0
