Impact of the Belding's ground squirrel, Spermophilus beldingi, on alfalfa production in northeastern California [PDF]

open access: yes, 1984
The Belding ground squirrel (Spermophilus beldingi) is found in rangeland, pasture, and various agronomic crops. However, its impact on agricultural production has been measured only rarely, e.g., by Grinnell and Dixon (1918) and Sauer (1976, 1977).

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Alfalfa Weevil Control In Alfalfa, 1995 [PDF]

open access: yesArthropod Management Tests, 1996
Abstract Experimental plots measuring 25 ft X 25 ft were established in a 2-yrold field of alfalfa ‘Pioneer 5333’ alfalfa in the vegetative state located in Ithaca, N.Y. Soils were silt loam. Five treatments and one untreated check were replicated 4 times in a RCB design.

Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.
