Small mammal abundance: Effect of N Addition on Vegetation With Mammalian Herbivory Initially on Disked Ground
This experiment is identical to E008 except the ground was disked thoroughly before the plots were laid out. From 1989-1994, plots with fertilizer treatment 1 were treated as complete controls (treatment 9), receiving no nutrients at all.
Small mammal abundance: Herbivore Effects on a Large, Unmanipulated Area
The purpose of this experiment was to measure herbivore effects over a large area that had not been manipulated rather than the 4 by 4 meter treatment I plots in E008 and E009. None of the plots in this experiment received any nutrients. Otherwise, the construction of this experiment is identical to E008 and E009.
Small Mammal Exclosure Study (SMES) Rabbit Feces Data from Chihuahuan Desert Grassland and Shrubland at the Sevilleta National Wildlife Refuge, New Mexico (1995-2005)
The purpose of this study is to determine whether or not the activities of small mammals regulate plant community structure, plant species diversity, and spatial vegetation patterns in Chihuahuan Desert shrublands and grasslands. What role if any do indigenous small mammal consumers have in maintaining desertified landscapes in the Chihuahuan Desert? Additionally, how do the effects of small mammals interact with changing climate to affect vegetation patterns over time? This is data for numbers rabbit fecal pellets counted on each of the Small Mammal Exclosure Study (SMES) plots. Rabbit fecal pellets were counted from each of the 36 one-meter2 quadrats twice each year when vegetation was measured.

LEEClab/Neotropical_Alien_Mammals: Neotropical Alien Mammals Database v. 1.0
<p>Here we release the first version of the Neotropical Alien Mammals Database: a dataset of occurrence and abundance of alien mammals in the Neotropics.</p> <p>The NEOTROPICAL ALIEN MAMMALS include a series of data about the composition and distribution of mammal species that were voluntarily or involuntarily introduced by humans into the Neotropics. The dataset has more than 600 collaborators and is composed for more than 73,000 records of alien mammals in 26 countries and Caribbean islands. The researchers responsible for this project are Clarissa Alves da Rosa (<a href="mailto:alvesrosa_c@hotmail.com">alvesrosa_c@hotmail.com</a>), Bruno Ribeiro (<a href="mailto:ribeiro.brr@gmail.com">ribeiro.brr@gmail.com</a>), Milton Cezar Ribeiro (<a href="mailto:miltinho.astronauta@gmail.com">miltinho.astronauta@gmail.com</a>) and Mauro Galetti (<a href="mailto:galetti@mac.com">galetti@mac.com</a>).</p>
