Using the PUMA System [PDF]

, 1985
This document describes the operation of the Lisp Machine interface to the Unimation Puma 600 Robot Arm. The interface is evolved from a system described in an earlier paper, and much is the same.

Abundance, trends, and challenges facing mountain goats throughout their North American distribution

Wildlife Society Bulletin, EarlyView.
Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

El jabalí europeo (Sus scrofa): Un invasor biológico como presa reciente del puma (Puma concolor) en el sur de Chile The European wild boar (Sus scrofa): A biological invader as a recent prey of the American puma (Puma concolor) in southern Chile

Revista Chilena de Historia Natural, 2012
Se estudió la dieta del puma (Puma concolor)en los anos 1988 y 2004 en los faldeos de los volcanes Mocho y Choshuenco, pluviselva valdiviana, sur de Chile, a través de la identificación de ítemes-presas en sus heces y la búsqueda en terreno de carcasas ...

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Human hunters are no substitute for vanishing apex predators

Journal of Animal Ecology, EarlyView.
Our study reveals that human hunters fail to replicate the collective and individual ecological functions of natural apex predators in sustaining biodiversity and promoting stable spatial patterns. These insights are vital for rethinking predator conservation and wildlife management in human‐dominated landscapes.

How Does SNAP Access Prior to Pregnancy Affect Maternal and Infant Health Outcomes?

The Milbank Quarterly, EarlyView.
Policy Points Reimposing work requirements for the Supplemental Nutrition Assistance Program—by removing temporary, location‐based waivers—causes a decline in food assistance participation among childless women. This loss of nutritional support prior to pregnancy is linked to tangible, negative health outcomes for their infants.

Rent control, rent overcharge, and racial disparity

Real Estate Economics, EarlyView.
Abstract Rent control policies have gained renewed legislative momentum in the United States, but are rent‐regulated landlords adhering to these policies? Answering this question is critical to understanding the policy's impact. Using a unique panel data set from the New York City Housing and Vacancy Survey (NYCHVS), we investigate noncompliance with ...
