We took a common activity used to teach adaptations, the bird beak lab, and modified it to integrate mathematical concepts like bar graphs and data analysis. While this interdisciplinary lesson targets third-grade science and mathematics standards, it also shows how mathematical ...

Indeed, a core feature of many notable anuran adaptations—including nesting behaviour—is the maintenance of an aquatic environment for developing offspring. The tight link between increasingly terrestrial reproduction and morphological, physiological and behavioural diversity in anurans provides inroads for ...
The gape of a bird’s beak is a fascinating and important aspect of avian biology. It influences feeding habits, parental care, communication, and survival strategies. Whether it’s the bright, colorful gapes of nestlings, the wide-mouthed aerial feeders, or the specialized adaptations of pelican...
Puerto Rico has 18 endemic bird species, each with its own adaptations and characteristics. Many of them thrive in the island’s forests, wetlands, and coastal regions. Note that some lists include or exclude different species in their list of endemic birds of Puerto Rico. Depending on the ta...
Consequently, prey adaptations that make predators attack less crucial body parts are expected to evolve. Marginal eyespots on butterfly wings have long been thought to have this deflective, but hitherto undemonstrated function. Methodology/Principal Findings: Here we report that a...
Rather, fowling at GH may have been a spatially and/ or temporary restricted activity, targeting those species that promised maximum hunting success with minimum effort. In contrast, fishing may have taken place year-round based on the presence of barbels of all size classes, but probably ...
The presence of cuckoo eggs in a wide variety of host nests in some small areas has been taken as evidence refuting the single-hosthypothesis. Nevertheless, most of the nests with nonmatching eggs are found in areas in which the ecology has been seriously altered by human activity. As a res...
