Microhabitat, microbiota, mitochondria and the epigenome shape the biparental legacy of heat exposure in a tropical arthropod
As technology and policy advance towards sustainable energy sources, humanity is reaching a critical climax regarding climate change. Average global surface temperatures have risen by 1oC since pre-industrial levels, and it is estimated that temperatures will continue to rise by at least 1.5oC …

The effects of parental experience on cognition, anxiety-like behaviour, and hippocampal plasticity in a biparental species.
… sexes of the same species, the degu. Degus are biparental rodents allowing us to examine maternal and paternal experiences in addition to maternal experience in single mothers when the male partner is removed (i.e., monoparental maternal experience). Key findings from our study indicated that …

How do parents respond to changing ecological and social environments: insights from a coral reef fish with biparental care
Phenotypic plasticity, the capacity of individuals to respond to changing environments by modifying traits, is critically important in allowing biological innovation in the face of environmental change. My dissertation used the clown anemonefish (Amphiprion percula) study system to explore …

Efecto moderador del tipo de familia (monoparental o biparental) sobre la relación entre el estilo de apego percibido y el autoconcepto en estudiantes universitarios
… por lo que el tipo de familia convencional: biparental, ha dado paso a un nuevo tipo de familia: monoparental. Por otro lado, el estilo de apego percibido durante la infancia puede influenciar en el desarrollo del autoconcepto de un individuo. Por lo tanto, el presente estudio pretende …

Pair Coordination of House Wrens, Troglodytes aedon, in Rural and Urban Environments
… of the environment poses many challenges to biparental avian species, however, it is unknown if urbanization affects pair coordination of provisioning behavior. We observed the parental behavior of pairs of house wrens (Troglodytes aedon) at active nests in an urban and rural site to explore …

Linkage disequilibrium and haplotype block patterns in popcorn populations
… population) from tropical and temperate origins (biparental population). Three populations were genotyped by genotyping-by-sequencing (GBS), 190 or 192 individual from each population. After the data quality control the final marker set remaining for analysis ranged from 75,000 to 76,055 SNPs. D’ …

The Evolution of Reproductive Complexity in Fishes
… <p>In Chapter 3, I investigate the evolution of biparental care in Cichlidae. I show that evolutionary transitions between biparental and maternal care have occurred frequently, highlighting the evolutionary lability of care in this group. I demonstrate that biparental care is associated with …

Assessing wild barley germplasm in multiparent and advanced backcross populations for mapping, gene discovery, and improvement of malting barley
… cultivar) x OUH-602 (wild barley accession), biparental AB population for yield and malting quality characteristics. The AB-NAM population was genotyped with 384 SNP markers and 263,531 markers were imputed onto the population from exome capture sequence of the parents. Linkage disequlibrium …

Physiological bases of parental care in the burying beetles, Nicrophorus orbicollis
… beetles, Nicrophorus orbicollis, have extended biparental care. They bury and prepare small vertebrate carcasses as food for their young. While females provide the most care, single males show a remarkable behavioral compensation after a mate loss. Here, I integrate behavioral and physiological …

Effects of exogenous androgens on parental care behaviour in male bluegill sunfish (Lepomis macrochirus)
… This research, however, comes from species with biparental care, where changes in behaviour of one parent can be compensated for by the other parent. I tested the validity of this trade-off by manipulating androgen levels in bluegill sunfish (Lepomis macrochirus), a species where males provide …

Offspring retrieval behaviors after brood loss in the convict cichlid
… become displaced from their nest. In monogamous biparental species, parents may share care of their young, including retrieval efforts. Convict cichlids (Amatitlania siquia) are an example of a monogamous biparental fish that show shared parental care of young. In the wild, these cichlids defend …

Understanding the genetic architecture of secondary domestication traits in Field Pennycress (Thlaspi arvense L.)
… panel of wild pennycress accessions, two biparental recombinant inbred populations, and three independent EMS-derived mutants to contribute knowledge and resources to understand important seed and agronomic characteristic traits in pennycress. Chapter 1 presents a literature review focused …

Genetic control of flowering time and biomass yield in sorghum
… Ma6, we also performed linkage mapping in two biparental populations (Tx623 x Tx2909 and Tx623 x Tx2910) thought to be segregating for functional variation at both Ma5 and Ma6. Linkage mapping results suggest that the architecture of the photoperiod-sensitivity response differs between these …

Population genetics of South African Protea L. (Proteaceae) species associated with various pollinator guilds

The evolution of parental care in insects
… male care, or female care followed sometimes by biparental care. Secondly, I investigate parental care trade-offs. I find that in insects, care is associated positively with offspring survival but negatively with fecundity, suggesting a general trade-off between current and future reproduction. …

THE ROLE OF PROLACTIN AND REPRODUCTIVE EXPERIENCE IN THE ONSET OF PARENTAL CARE IN THE ZEBRA FINCH (TAENIOPYGIA GUTTATA)
… (chapter 2) in the socially monogamous and biparental zebra finch. In chapters 3 and 4, we provide the first causal evidence that PRL plays a role in the onset of zebra finch parental behavior and show that reproductive experience positively affects parental behavior. Lastly, in chapter 5, …
