Van de veertiende tot midden negentiende eeuw vonden twee belangrijke verschuivingen plaats in het denken over dieren. Enerzijds werd theologisch antropocentrisch stap voor door wetenschappelijke inzichten verlaten en mens onttroond. Met ontwikkeling van evolutieleer vond anderzijds een paradigmaverschuiving plaats: verwantschap met andere dieren duidelijk. toen af aan nam zoektocht naar gelijk...

Submerged shell midden sites and natural shell deposits can have similar characteristics and can be difficult to distinguish archaeologically. We excavated two test units from a large (at least 35 m×70 m) submerged shell mound in Fort Neck Cove in southern Rhode Island to assess whether it was natural or cultural in origin. This mound had been recognized as a potential archaeological feature as...

Some animals modify the environment in ways that can influence the resources available to other species. Because red squirrels (Tamiasciurus hudsonicus) create large piles of conifer-cone debris (middens) in which they store cones, squirrels concentrate resources that might affect biodiversity locally. To determine whether other animals are attracted to midden sites beyond their affinity for th...
