Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals respond differently temperature in different parts their range. To date, there have been few tests this assumption at scale continents, so it is unclear if large-scale problem. Here, we examined that insect taxa show 96 sites grassy habitats North America. We sampled insects with Malaise traps during 2019-2021 (N = 1041...
Abstract Hormones are central regulators of organismal function and flexibility that mediate a diversity phenotypic traits from early development through senescence. Yet despite these important roles, basic questions about how why hormone systems vary within across species remain unanswered. Here we describe HormoneBase, database circulating steroid levels their variation vertebrates. This aims to provide all available data on the mean, variation, range plasma glucocorticoids (both baseline...
Abstract Animals must balance various costs and benefits when deciding to breed. The of breeding at different times have received much attention, but most studies been limited investigating short‐term season‐to‐season fitness effects. However, early, versus late, in a season may influence lifetime over many years, trading off complex ways across the breeder’s lifespan. In this study, we examined complete life histories 867 female tree swallows ( Tachycineta bicolor ) Ithaca, New York,...
Abstract A cooling trend in summer (May–August) daytime temperatures since the mid-twentieth century over central United States contrasts with strong warming of western and eastern States. Prior studies based on data through 1999 suggested that this so-called hole arose mainly from internal climate variability thus would likely disappear. Yet it has prevailed for two more decades, despite accelerating global warming, compelling reexamination causes addition to natural could include...
Artificial light at night (hereafter "ALAN") affects 88% of the land area in Europe and almost half USA, with even rural areas exposed to lights from agricultural industrial buildings. To date, there have been few studies that assess impacts ALAN on both wildlife behavior physiology. However, may alter energy expenditure and/or stress physiology during breeding period, potentially reducing reproductive success resulting conservation implications. Here, we experimentally adult female nestling...
Abstract As the global climate shifts, many species are imperilled by changing thermal regimes. Despite rising temperatures, some populations must contend with more frequent or extreme cold. In these populations, ability to cope cold may be an important determinant of fitness. Experiments in captive animals have shown that rapid temperature declines typically elicit increase glucocorticoid hormones (mediators stress response); however, it is not known whether free‐living adults, which better...
Abstract Early‐life conditions can have substantial effects on the ways animals respond to stressors as adults. In particular, thermal during development affect juveniles' responses stressors, and there is evidence that these may extend into adulthood. However, remain poorly understood, especially in free‐living organisms. We test prediction ambient temperatures laying, embryonic nestling hormonal mediators of response To do so, we use a long‐term dataset tree swallows ( Tachycineta bicolor...
Corticosterone, the main glucocorticoid in birds, is a major mediator of incredible physiological feat migration. Corticosterone plays important roles migration, from preparation to in-flight energy mobilization refueling, and corticosterone levels often show distinct elevations or depressions during certain stages migratory process. Here, we ask whether corticosterone's role migration shapes its modulation other life-history stages, as case with some phenotypically flexible traits involved...
The social environment that individuals experience appears to be a particularly salient mediator of stress resilience, as the nature and valence interactions are often related subsequent health, physiology, microbiota, overall resilience. Relatively few studies have simultaneously manipulated ecological challenges under natural conditions. Here, we report results experiments in wild tree swallows (Tachycineta bicolor) which both (predator encounters flight efficiency reduction) (by...
Tree swallows are North American birds that can help us understand more about biology. We already know a lot tree because they easy to work with. These popular for scientists study. bird health, migration, and nesting of swallows. However, declining climate change, insect loss, habitat destruction. You by becoming community scientist! fascinating everyone conserve. And along the way, we learn our world.
The risk of predation directly affects the physiology, behavior, and fitness wild birds. Strong social connections with conspecifics could help individuals recover from a stressful experience such as event; however, competitive interactions also have potential to exacerbate stress. Few studies investigated interaction between environmental stressors landscape in bird populations. In 2 years field studies, we experimentally simulated attempts on breeding female tree swallows (Tachicyneta...
Abstract Life history theory provides a framework for understanding how trade-offs generate negative trait associations. Among nestling birds, time spent in the nest, risk of predation, and lifespan covary, but some associations are only found within species while others observed between species. A recent comparative study suggests that allocation may be alleviated by disinvestment ephemeral traits, such as nest-grown feathers, quickly replaced. However, direct resource cannot inferred from...

Abstract COVID‐19 created a host of challenges for science education; in our case, the pandemic halted in‐person elementary school outreach project on bird biology. This was designed as year‐long program to teach fifth‐grade students Ithaca, New York, USA, about ecology and biodiversity using presentations, games, activities, outdoor demonstrations. As central part this effort, we set up nest boxes property planned monitor them with during breeding spring. Here, describe experiences...
ABSTRACT Life history theory provides a framework for understanding how trade-offs generate negative trait associations. Among nestling birds, developmental rate, risk of predation, and lifespan covary, but some associations are only found within species while others observed between species. A recent comparative study suggests that allocation may be alleviated by disinvestment in ephemeral traits, such as nest-grown feathers, quickly replaced. However, direct resource cannot inferred from...
Speciation provides a framework for classifying biodiversity on Earth and is central concept in evolutionary biology. To help undergraduate students learn about speciation, we designed student-centered lesson that uses active-learning techniques (e.g., clicker questions, small group work, whole class discussion) compares multiple species concepts (morphological, biological, phylogenetic) using giraffes as an example. Giraffes were chosen the focus of this because they are familiar have broad...

Bird eggs come in a wide variety of shapes and recent large-scale studies across species have renewed interest understanding the factors that generate maintain this diversity. However, these advances largely overlook fact egg shape also varies dramatically within species: between populations, individuals, produced by same individual. We measured size 1382 205 tree swallows ( Tachycineta bicolor ) 259 nests with many females having two or three years. found intra-specific variation asymmetry...
