Why Does It Take Two To Tango? Lifetime Fitness Consequences Of Parental Care In A Burying Beetle, Ashlee N. Smith, J. Curtis Creighton, Mark C. Belk
Faculty Publications
In species that require parental care, each parent can either care for their offspring or leave them in the care of the other parent. For each parent this creates three possible parental care strategies: biparental care, uniparental (male or female) care, and uniparental desertion by either the male or female. The burying beetle, Nicrophorus orbicollis, typically exhibits biparental care of offspring, and thus provides a unique system that allows us to compare the fitness benefits of these parental care strategies in an unconfounded way. In this study, we assess the lifetime fitness of biparental care, uniparental care, and uniparental …

© The Author 2017. Squirrel monkeys, Saimiri, are commonly found in zoological parks and used in biomedical research. S. Boliviensis is the most common species for research; however, there is little information about genome evolution within this primate lineage. Here, we reconstruct the Alu element sequence amplification and evolution in the genus Saimiri at the time of divergence within the family Cebidae lineage. Alu elements are the most successful SINE (Short Interspersed Element) in primates. Here, we report 46 Saimiri lineage specific Alu subfamilies. Retrotransposition activity involved subfamilies related to AluS, AluTa10, and AluTa15. Many subfamilies are simultaneously active within …

© 2017 John Wiley & Sons Ltd/CNRS Population cycling is a widespread phenomenon, observed across a multitude of taxa in both laboratory and natural conditions. Historically, the theory associated with population cycles was tightly linked to pairwise consumer–resource interactions and studied via deterministic models, but current empirical and theoretical research reveals a much richer basis for ecological cycles. Stochasticity and seasonality can modulate or create cyclic behaviour in non-intuitive ways, the high-dimensionality in ecological systems can profoundly influence cycling, and so can demographic structure and eco-evolutionary dynamics. An inclusive theory for population cycles, ranging from ecosystem-level to demographic modelling, grounded …
Interaction Between Predation Environment And Diet Constrains Body Shape In Utah Chub, Gila Atraria (Cypriniformes: Cyprinidae), Trevor J. Williams, Jerald B. Johnson, Mark C. Belk
Interaction Between Predation Environment And Diet Constrains Body Shape In Utah Chub, Gila Atraria (Cypriniformes: Cyprinidae), Trevor J. Williams, Jerald B. Johnson, Mark C. Belk

Evolution typically occurs in response to a suite of selective pressures. Yet, many studies of natural selection in the wild only investigate a single selective agent at a time. This can be problematic when selective agents act in non-additive ways. Here we evaluate the interactive effects of diet and predation on the evolution of body shape in the cyprinid fish Utah chub (Gila atraria). We found that both factors and the interaction between them are significant predictors of body shape. This interaction is likely a result of different forms of selective pressures, where predation is a stabilizing selective …
Merging Massive Black Holes The Right Place And The Right Time, Astrid Lamberts, G. González, R. Hynes
Merging Massive Black Holes The Right Place And The Right Time, Astrid Lamberts, G. González, R. Hynes

The LIGO/Virgo detections of gravitational waves from merging black holes of ≃ 30 solar mass suggest progenitor stars of low metallicity (Z/ZO ≤ 0.3). In this talk I will provide constrains on where the progenitors of GW150914 and GW170104 may have formed, based on advanced models of galaxy formation and evolution combined with binary population synthesis models. First I will combine estimates of galaxy properties (star-forming gas metallicity, star formation rate and merger rate) across cosmic time to predict the low redshift BBH merger rate as a function of present day host galaxy mass, formation redshift of the progenitor system …

Australopiths exhibit a number of derived facial features that are thought to strengthen the face against high and/or repetitive loads associated with a diet that included mechanically challenging foods. Here, we use finite element analysis (FEA) to test hypotheses related to the purported strengthening role of the zygomatic root and "anterior pillar" in australopiths. We modified our previously constructed models of Sts 5 (Australopithecus africanus) and MH1 (A. sediba) to differ in the morphology of the zygomatic root, including changes to both the shape and positioning of the zygomatic root complex, in addition to creating variants of Sts 5 lacking …
