Summary: The study found that Brown Pelicans in Tampa Bay, Florida are frequently entangled in fishing gear, especially on piers with extensive perches. The number of entanglements can be reduced by deterring pelicans from perching near piers or reducing fishing near areas where pelicans perch.

Summary: The flight restriction of great white pelicans does not seem to have a significant impact on welfare indicators, adrenal activity, or behavior assessed in this study. However, reversibly deflighted pelicans showed higher levels of stress indicator CORTf compared to irreversibly deflighted and airworthy pelicans. Additionally, group size of the pelicans may influence their welfare, with larger groups having lower stress levels.

Summary: Brown Pelican populations are recovering in coastal areas of North and Central America, but the recovery rates vary. Factors such as population density and the Southern Oscillation Index have an impact on population dynamics. Understanding the driving factors behind Brown Pelican population recovery can help in implementing conservation measures during lesser-known periods.

Summary: This study demonstrates that the physiological rhythm of glucocorticoids plays a crucial role in regulating BAT function, and long-term flattening of corticosterone levels can lead to adiposity.

Summary: Environmental pollution by metals can affect wildlife health. Some metals have an impact on the neuroendocrine stress response and can cause oxidative stress. This study investigates the association between metals and neuroendocrine stress activity, as well as biomarkers of oxidative stress in captive female Morelet's crocodiles.

Summary: This study explores the link between behavioral and biological features of stress responses in the brain. It identifies the involvement of the medial prefrontal cortex (mPFC) and midbrain dorsolateral periaqueductal gray (PAG) in active stress coping behaviors, while a different circuit involving the rostral mPFC and ventrolateral PAG limits passive behaviors. Furthermore, the activation of the caudal mPFC-dorsolateral PAG projection can attenuate the increase in stress hormone output and immobility associated with a passive coping response. These findings provide insights into how the brain coordinates different responses to stress and contributes to stress resilience.

Summary: This study suggests that male rats with high-CORT stress responsiveness exhibit increased anhedonia and passive coping responses in adulthood following peripubertal stress exposure. Additionally, exposure to peripubertal stress leads to increased hippocampal TNF-alpha expression, which correlates with passive coping responses. Furthermore, peripubertal stress has long-term effects on hippocampal microglia, particularly in high-CORT stress-responsive rats.

Summary: Chronic stress and alcohol use disorder have a reciprocal relationship and hinder recovery from both disorders. This study identified the TRPV6 channel as being involved in stress, corticosterone, and alcohol-induced intestinal permeability, microbiota dysbiosis, systemic inflammation, and liver damage. TRPV6 deficiency also blocked the effects of stress and stress-mediated potentiation of alcohol-induced dysbiosis of gut microbiota.

Summary: This study compared the stress responses of animals exposed to different stressors to those of animals subjected to paradoxical sleep deprivation (PSD). The results showed that the pituitary-adrenal response to PSD was similar to that induced by psychological stress.

Summary: This study investigated the acute effects of fraxetin in a chronic unpredictable stress (CUS) paradigm. The results demonstrated that fraxetin decreased depression-like behavior and anxiety, improved memory deficits, and restored altered neurochemical levels. These findings suggest a potential application of fraxetin in managing anxiety and depression. However, further research is needed to explore the chronic effects of fraxetin.

Summary: The study demonstrates the neuroprotective efficacy of Thuja occidentalis in treating diabetic neuropathy. It effectively corrects the levels of inflammatory markers and oxidative stress caused by hyperglycemia, leading to the restoration of neuronal functions. The hypoglycemic, antioxidant, anti-hyperalgesia, and anti-inflammatory properties of Thuja occidentalis are responsible for its neuroprotective benefit.

Summary: Species reintroductions are an important part of conservation, but understanding the past baselines is crucial. This study examines the extinction dynamics of the Dalmatian Pelican in Britain and finds uncertain evidence of its presence and disappearance. The research provides a framework for integrating past environmental baselines into conservation decision-making and reintroduction feasibility assessments.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
