• Fecal glucocorticoid metabolite analysis as an indicator of stress during translocation and acclimation in an endangered large mammal, the Grevy's zebra (2008, background): “Romero, 2002 ). Measurement of FGMs in Lewa controls from the two different times of year was important to control for possible seasonal changes in FGMs during the study period.”
• How and why the winner effect forms: influences of contest environment and species differences (2010, result): “Certainly, this line of thinking agrees with additional analyses in birds that suggest that circulating hormones like Cort might be elevated in individuals when the risk of being stressed is both high and foreseeable (Romero 2002; Bokony et al. 2009).”
• Collecting baseline corticosterone samples in the field: is under 3 min good enough? (2005, background): “Since many species show seasonal variation in their glucocorticoid concentrations (Romero, 2002), and many of these data were collected to demonstrate that phenomenon, we performed separate analyses for each species at each time of year.”
• STRESS IN FREE-RANGING MAMMALS: INTEGRATING PHYSIOLOGY, ECOLOGY, AND NATURAL HISTORY (2005, background): “That corticosteroid-binding globulin serves to bind excess glucocorticoids and hence protect tissues from excessive levels of glucocorticoids has been referred to as the ‘‘buffer hypothesis’’ (Romero 2002) and is contrary to the alternative ‘‘carrier hypothesis.’’”
• Stress hormones link food availability and population processes in seabirds (2007, background): “First, CORT production in birds may reflect population-specific parameters and/or endogenous changes in the physiology of individuals at different stages of their life cycle (i.e. Wingfield 1994, Romero et al. 1997, Kitaysky et al. 1999b, Romero 2002).”
• Stress in Yucatan spider monkeys: effects of environmental conditions on fecal cortisol levels in wild and captive populations (2009, background): “As in many other vertebrates (Romero, 2002), cortisol seems to vary seasonally in spider monkeys.”
• Glucocorticoid Hormone Levels Increase with Group Size and Parasite Load in Cliff Swallows (2006, background): “In free-living animals, high levels of these hormones are often associated with adverse events, such as severe weather that restricts food supply, exposure to deleterious parasites or pathogens or increased likelihood of encountering a predator (Wingfield et al. 1983, 1994b, 1995; Dunlap & Schall 19”
• Effects of habituation, research and ecotourism on faecal glucocorticoid metabolites in wild western lowland gorillas: Implications for conservation management (2014, background): “Environmental stressors are not equal across individuals or groups, and FGCM differences may be related to seasonal, diet, and life history differences (Romero, 2002) as well as behavioural differences (Muehlenbein et al., 2012).”
• Corticosterone and brood abandonment in a passerine bird (2012, background): “1984), peaking with increased activity and energy demands (Romero 2002; Lormée et al. 2003).”
• What are you actually measuring? A review of techniques that integrate the stress response on distinct time‐scales (2020, background): “Blood Cort levels change with life-history stage (e.g. Lattin et al., 2012; Romero, 2002) and during repeated stress (e.g. Cyr, Earle, Tam, & Romero, 2007).”
• The ecology of stress: effects of the social environment (2013, background): “…effects of reproductive condition, seasonality or recent extreme weather events on HPA axis activity or responsiveness (Kenagy & Place 2000; Romero 2002; Romero et al. 2008) or to the effects of trapping/handling stress on glucocorticoid levels (Kenagy & Place 2000; Sheriff et al. 2011a).”
• Acute phase responses of passerine birds: characterization and seasonal variation (2007, background): “Another physiological cascade that varies on a seasonal level is the avian adrenocortical stress response (Romero 2002).”
• Stress, corticosterone responses and avian personalities (2007, background): “Corticosterone responses have been measured in many species of birds in different situations and at different times of year (Silverin 1998; Romero 2002).”
• Glucocorticoid-Mediated Phenotypes in Vertebrates : Multilevel Variation and Evolution (2016, background): “The activity of the HPA axis also varies rather dramatically with the life history state an individual is in, a topic excellently summarized elsewhere 52 M. Hau et al. Advances in the Study of Behavior, First Edition, 2016, 41e115 (Romero, 2002).”
• Monitoring stress in captive giant pandas (Ailuropoda melanoleuca): behavioral and hormonal responses to ambient noise (2004, background): “Baseline corticoid levels and the pituitary-adrenal response to stress often vary in mammals depending on reproductive status [e.g., Boonstra et al., 2001; Romero, 2002 ].”
