Mammals that cope with harsh environmental conditions by hibernating show seasonal variation in body mass, as fat reserves are accumulated during summer and depleted during winter. Hence, pre-hibernation mass is often considered a key phenotypic trait in hibernating species that can be an indicator

Native species are threatened by the introduction of non-native and invasive organisms.

To the Editor.— The response to my painting, Pitkin County , on the cover of the Sept 23 issue was a pleasant surprise. The many inquiries and compliments I received from physicians who saw the cover are both encouraging and rewarding. I thank the staff ofThe Journalfor its fine presentation of my p

The abundance of insect herbivores, such as aphids, is mediated by interactions with

Dispersal is integral to the ecology and evolution of communities. Dispersal affects bacterial communities by impacting bacterial composition and diversity in many environments. One such environment is floral organs. Flowers are nutrient-rich environments for diverse and abundant microbes. Floral mi

Age effects on maximum running speed (MRS) in yellow-bellied marmots (Marmota flaviventris) were examined to see whether this performance trait varied with age. Individuals were trapped in Tomahawk livetraps, then released and encouraged to run to burrows by yelling and chasing over varying distance

Abstract Potatoes were planted 17 May at the Research Farm of the Red River Valley Potato Growers Association. Plots were four rows wide, 60 ft long, with 38 in rows and 12 in between plants. Plots were separated on all sides by 6.3 ft of cultivated soil. The experiment had a complete randomized plo

Identifying forces that affect population dynamics can allow us to better understand the

Diptera play a critical role in alpine and subalpine ecosytems, though they are little studied in terms of what guides their timing and abundance. In order to reveal what cues dipteran timing this study was conducted for 24 years, using a Malaise trap to capture the insects, dipteran distributions w
