Dads matter: causes and consequences of plasticity in paternal care
… unexplored possibility is that in species with paternal care, fathers adjust their parenting in response to stressors, and adjustments in care have long-term consequences for offspring (as has been shown for mothers). Here, I report a series of studies examining how plasticity in father behavior …

The neural regulation of fatherhood, insights from the anemonfish amphiprion ocellaris
Parental care is a fundamental social behavior exhibited ubiquitously in diverse lineages across the animal kingdom, and when present is critical for offspring survival. Parental care represents a conflict: should parents invest in offspring fitness at the consequence of forgone reproductive …

Neurogenomic dynamics following social interactions in male threespined sticklebacks
… and compared and contrasted the neurogenomics of paternal care with the neurogenomics of the response to a territorial challenge. Males experienced dramatic neurogenomic shifts while they were providing paternal care. Genes related to hormones that change in mammalian mothers during pregnancy and …

Natural history of the social millipede Brachycybe lecontii (Wood, 1864)
… known for forming pinwheel-shaped groups and for paternal care of eggs. Brachycybe lecontii is endemic to the eastern U.S., and its distribution overlaps with another species within the genus, Brachycybe petasata, from the Southern Appalachian Mountains. Molecular data, however, show that the …

The individual and collective behavior of social organisms across environments
… the “common” type that exhibits typical paternal care and the “white” ecotype where paternal care is significantly reduced. I found that the white ecotype is bolder than the common ecotype. There were also social network differences, with the white ecotype having lower clustering …

Comparisons of the socio-behavioral differences between chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), investigating the impact of a naturally occurring polymorphic microsatellite deletion in the 5’ flanking region of arginine vasopressin receptor 1a (AVPR1a) on gene expression and sociality within the Pan genus
… associated with social behaviors (pair-bonding, paternal care, degree of social interest) and differential levels of expression of AVPR1a in the brains of voles. The polymorphic DupB microsatellite in chimpanzees allows the investigation of microsatellite variation 5’ of AVPR1a in higher order …

Perceptions of Parental Care and Overprotection in Childhood: Influences on the Neurobiological Adaptation to Motherhood
<p>Recalled memories of caregiving in childhood are especially salient during the postpartum period and inform mothers’ conceptualization of her new parenting role. Positive perceptions of care received from one’s parents are related to improved maternal-infant bonding and positive parenting …

Solitary, reproductive, and parental behavior of maned wolves (Chrysocyon brachyurus)
… the family Canidae, which is known for extensive paternal care. Thus, the maned wolf is an interesting species for studying parental investment theory. I studied maned wolves in U.S. zoos and in Emas National Park, Brazil to gather information necessary for developing conservation plans while …

Sex-specific investment in incubation and the reproductive biology of two tropical antbird species
Paternal care has been neglected in behavioral studies because it is rare among most animals. Birds express wide variation in male care across a broad life-history gradient, but such variation among species remains poorly explored. At the same time, contributions of male assistance with incubation …

Exploring the fathering brain: insights from neural activation
… shift from being aggressive toward intruders to carefully tending young. A variety of studies have focused on how the brain changes at the beginning or end of the breeding season (Gozdowska et al., 2006; Hairston et al., 2003; Meitzen et al., 2009; Nakao et al., 2008; Paul et al., 2009), but less …

The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish
… attenuation of the stress response during early paternal care in smallmouth bass (Micropterus dolomieu). In response to a stressor, males guarding free-swimming fry but not eggs elevated plasma ACTH and cortisol as well as mRNA levels of key HPI axis genes. These results point to a hypoactive HPI …

Effects of urbanization on the physiology, behavior, and fitness of a wild songbird
… other reproductive behaviors such as maternal care. Indeed, female song sparrows, like males, expressed increased aggressive signaling compared to rural, suggesting urban habitats may favor a more aggressive phenotype. Finally, in Chapter 3, I investigated the consequences of increased male …

The Influence of Reduced Forest Cover and Dissolved Oxygen on the Viability of Eggs from Eastern Hellbenders (<i>Cryptobranchus alleganiensis</i>)
… male hellbenders normally provide extensive paternal care to embryos and larvae over an 8-month period. However, researchers have recently discovered that in degraded populations, hellbender nests are failing due to whole-clutch filial cannibalism by adult males. The underlying mechanism that …

Impacts of population-level reproductive success on recruitment dynamics in largemouth bass (Micropterus salmoides)
… exploited sport fish that provides exclusively paternal care to its offspring during the reproductive season each spring. While recreational anglers can negatively impact reproductive success of individuals by capturing nesting males, interrupting parental care, and thus facilitating higher …

The Evolution of Reproductive Complexity in Fishes
… I present a systematic review of parental care for 294 families (close to 60%) of bony fish and show that male-only care is the predominant form of care in this group. I summarize current theories on parental care, emphasizing external fertilization, certainty of paternity, and …
