This protocol synthesizes multi-agency efforts to measure soil water content using buried in situ sensors.
Protocol for Assessing the Relative Effects of Environment and Genetics on Antler and Body Growth for a Long-lived Cervid Eric S. Michel1,2, Emily B. Flinn1, Stephen Demarais1, Bronson K. Strickland1, Guiming Wang1, Chad M. Dacus3 1Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, 2Department of Natural Resource Management, South Dakota State University, 3Mississippi Department of Wildlife, Fisheries and Parks Phenotypic differences among cervid populations may be related to population-level genetics or nutrition; discerning which is difficult in the wild. This protocol describes how we designed a controlled study where nutritional variation was eliminated. We found that phenotypic variation of male white-tailed deer was more limited by nutrition than genetics.
How to Create Conditioned Taste Aversion for Grazing Ground Covers in Woody Crops with Small Ruminants Carmen L. Manuelian1, Elena Albanell1, Maristela Rovai1,2, Gerardo Caja1 1Group of Ruminant Research (G2R), Department of Animal and Food Science, Universitat Autònoma de Barcelona, 2Dairy Science Department, South Dakota State University Feeding behavior preferences in livestock can be modified to implement a grazing management plan in woody crops. Here, we present a protocol to show a lithium chloride dose after eating a new plant that induces conditioned taste aversion.
