Summary: The predation risk affects the costs and benefits of prey life-history decisions, especially during reproduction. Hormones like prolactin and corticosterone mediate the impact of predation risk on avian parental investment decisions, making them ideal tools for studying trade-offs involved. Contrary to predictions, prolactin levels showed a positive correlation with nest predation risk in this study on common eiders breeding in the Baltic Sea.

Summary: This study characterized the circulating levels of key hormones involved in reproduction in rock doves and found that males had high testosterone levels during nest-building or egg-laying, while prolactin increased at mid-incubation and corticosterone levels were elevated in later incubation and early nestling development. Experimental manipulations showed that males responded quickly to nest loss by increasing testosterone, but this response was muted when nest loss occurred early in reproduction. Females, on the other hand, either did not change or decreased in hormone levels following nest manipulation, suggesting a decrease in reproductive processes.

Summary: In birds, the duration and types of parental care and attachment vary depending on the species, developmental strategies, and life history traits. Both male and female individuals can provide parental care, which includes nesting, laying, and hatching. Neuroendocrine responses play a crucial role in motivating these behaviors, which are vital for offspring survival, social bonding, intergenerational learning, and reproductive success. This review aims to examine the behavioral and endocrine systems of parental care and newborn attachment in birds during each post-hatching stage.

Summary: Seabirds breeding sympatrically in the Gulf of St-Lawrence differentiate in diet and foraging range, with smaller diving birds consuming smaller prey items closer to the colony, larger divers selecting larger prey due to their deeper diving capability, and surface foragers expanding their foraging range to compensate. This niche differentiation allows for coexistence and provides insight into multispecies colonial living.

Summary: The study of Common Murre eggs on Skomer Island showed significant variations in ground colors and maculations among females, with eggs laid in different years by the same female being more similar to each other. This indicates a consistency in the appearance of eggs laid by female Common Murres within and between breeding seasons.

Summary: This study found that parental breeding time affects the sensitivity of European common frogs to nitrate pollution at different life stages. Breeding later in spring reduces hatching size and survival rate, but also induces compensatory growth. Nitrate exposure reduces developmental rate and results in larger but older larvae that are more sensitive to warmer temperatures. However, standard metabolic rate is not affected by parental breeding time or nitrate exposure. Exposure to nitrate pollution during embryonic and larval stages influences the temperature sensitivity of juvenile frogs.

Summary: Hosts with long coevolutionary history with parasites often assume negligible fitness costs of chronic infection. However, experimental manipulation of infections reveals effects of parasites on hosts during reproduction. In this study, the authors found that reducing haemosporidian infections in red-winged blackbirds resulted in significant benefits to mothers and their offspring.

Summary: Anthropogenic environmental change, including climate change and urbanization, leads to warmer temperatures in terrestrial and aquatic habitats, affecting community assemblages and introducing invasive species. Changes in environment can have negative effects on anuran species, including reducing fitness and altering physiology and behavior. This study focuses on the response of Gulf Coast toads (Incilius nebulifer) to warmer water, reduced water levels, and invasive species, examining the role of corticosterone in modulating their response. The results show that tadpoles reared in warmer water and reduced water levels had elevated baseline corticosterone release rates, and toadlets exposed to multiple treatments showed an increased stress response. Additionally, exposure to the predatory red imported fire ant led to reduced predator avoidance and altered growth patterns in toadlets. Despite these challenges, Gulf Coast toads were able to persist by adjusting their physiology and behavior.

Summary: This study validates the Parental Participation in the Environment (PPE) scale and provides a novel measure to assess pro-environmental socialization via parental participation. The study confirms the validity of the PPE scale and reveals relationships among parents' PPE, pro-environmental behavior, and connectedness with nature based on data analysis.

Summary: Anthropogenic noise has been found to alter adult behavior, impacting nestling body condition in Eastern Bluebirds. However, there were no significant differences in baseline corticosterone levels or telomere lengths between nestlings exposed to noise and those in the control group, suggesting that the effects of noise on offspring may be short-term rather than long-term.

Summary: In the face of challenges, animals must balance investments in reproductive effort versus their own survival. Experienced birds that had raised chicks showed lower stress-induced cortisol and higher stress-induced prolactin levels, as well as higher expression of glucocorticoid receptors in the hippocampus, indicating potential mechanisms by which gaining parental experience may improve parental performance and fitness.

Summary: The study found that in biparental care in ravens, mothers are more likely to invest and care for offspring, while paternal care is selective and tends to favor heavier sons. Brood size affects chicks' begging behavior, but decreases their chances of being fed.

Summary: Maternal care in early life is crucial for the growth and development of offspring. This study compared the effects of maternal separation during the light and dark phases of the circadian cycle on the behavior and physiology of adult male rats. The results showed that light-phase stress had a greater impact on emotional behavior during the first two weeks of life, while dark-phase stress had a greater impact on the functioning of the Hypothalamus-Pituitary-Adrenal axis. The study provides empirical support for the effects of early-life stress on offspring.

Summary: Although research on the avian hippocampus has been limited, it is crucial for understanding its evolution and changes over time. The avian hippocampus plays important roles in spatial cognition as well as regulating anxiety, approach-avoidance behavior, and stress responses. Future research should focus on elucidating the cellular and molecular mechanisms, including endocrinology, to resolve outstanding questions about avian hippocampal function and organization.

Summary: This study investigates the effects of urbanization on hormone levels in tungara frogs and found that urban frogs and forest frogs have different endocrine phenotypes. Exposure to urban noise and light pollution led to an increase in testosterone and a decrease in corticosterone in urban frogs, while forest frogs showed no endocrine response to sensory pollutants. These results suggest that urbanization can modulate hormone levels and influence behavior in frogs.
