An Inexpensive Flow-Bench for Mechanical Engineering Labs Open
A flow-bench is a valuable piece of lab equipment useful for various mechanical engineering flow experiments. For example, in an Internal Combustion (IC) engines course students can test modifications to cylinder heads (valve lift, valve s…

Rewilding and Indigenous Community‐Led Land Care Open
In the 1990s, pioneers of rewilding described a bold vision of wilderness connected at the continental scale, with thriving populations of large, wild animals. Much of the resulting discourse has emphasized uninhabited places or has promot…

Extinction of the Tasmanian emu and opportunities for rewilding Open
The Tasmanian emu (Dromaius novaehollandiae diemenensis) persisted alongside Aboriginal people for ∼40,000 years, for the last ∼14,000 years of which Tasmania was a large, continental island. This population of emus was extirpated soon aft…

Asynchronous range shifts drive alpine plant–pollinator interactions and reduce plant fitness Open
Climate change is driving species' range shifts, which are in turn disrupting species interactions due to species‐specific differences in their abilities to migrate in response to climate. We evaluated the consequences of asynchronous rang…

Impact of Mafic Underplating and Mantle Depletion on Subsequent Rifting: A Numerical Modeling Study Open
Orogenesis in the Variscan belt of Western Europe was followed by a major magmatic event during the Permian that formed a mafic lower crust by crystallizing pyroxenite and gabbros from mantle‐derived melts at the base of the continental cr…

Coexistence and competitive exclusion in mutualism Open
The competitive exclusion principle is fundamental to understanding coexistence. Well‐established theories predict the conditions for coexistence in consumer–resource interactions. Given that species often compete for commodities offered b…

Linkages between nectaring and oviposition preferences of <i>Manduca sexta</i> on two co‐blooming <i>Datura</i> species in the Sonoran Desert Open
1. The oviposition choices of phytophagous insects determine the environment that their offspring will experience, affecting both larval performance and host plant fitness. These choices, however, may be influenced by other activities, suc…
