Statistical models relating peak expiratory flow rates to age, height, and weight in men and women.

An epidemiological survey of 1239 normal subjects without respiratory symptoms was undertaken in an urban locality of New Delhi in 1974. The subjects were divided into males aged under or over 22 and females under or over 17. Various statistical models were calculated to relate peak expiratory flow rate to the age, height, and weight of the subjects in each group. The linear model was simple, c...

Trophic redundancy reduces vulnerability to extinction cascades

Current species extinction rates are at unprecedentedly high levels. While human activities can be the direct cause of some extinctions, it is becoming increasingly clear that species extinctions themselves can be the cause of further extinctions, since species affect each other through the network of ecological interactions among them. There is concern that the simplification of ecosystems, du...

Larger brain size indirectly increases vulnerability to extinction in mammals.

Although previous studies have addressed the question of why large brains evolved, we have limited understanding of potential beneficial or detrimental effects of enlarged brain size in the face of current threats. Using novel phylogenetic path analysis, we evaluated how brain size directly and indirectly, via its effects on life history and ecology, influences vulnerability to extinction acros...

Extinction vulnerability of coral reef fishes

With rapidly increasing rates of contemporary extinction, predicting extinction vulnerability and identifying how multiple stressors drive non-random species loss have become key challenges in ecology. These assessments are crucial for avoiding the loss of key functional groups that sustain ecosystem processes and services. We developed a novel predictive framework of species extinction vulnera...

Plant height and evolutionary games

In plants, investment in height improves access to light, but incurs costs in construction and maintenance of the stem. Because the benefits of plant height depend on which other height strategies are present, competition for light can usefully be framed as a game-theoretic problem. The vertical structure of the world’s vegetation, which is inefficient for plant growth, can then be understood a...
