Nuisance Neonatives Guidelines for Assessing Range-Shifting Species Nuisance Neonatives Guidelines for Assessing Range-Shifting Species
Native species will need to shift their ranges northward and upslope to keep pace with climate change in the Northeast U.S. However, this may cause some range-shifting species to have undesirable consequences in their expanded range. We provide a framework to identify the likelihood that a range-shifting species will become problematic and offer suggestions to minimize impacts from these...

Standardized guide to the examination and necropsy of the horseshoe crab using Limulus polyphemus as Limulidae prototype Standardized guide to the examination and necropsy of the horseshoe crab using Limulus polyphemus as Limulidae prototype
The Atlantic, or American, horseshoe crab (Limulus polyphemus) has existed largely unchanged for over 100 million years. Millions of individuals are commonly observed ashore in spring and summer months during spawning events along the entire North American coastline expanding from the East to the Gulf coasts of the United States and Mexico. Other species can be found in the Indian and...
