Within-season woody plant growth: Patterns, characteristics, and sensitivity to weather variation as an indicator of vegetation response to climate change
Aluminum spring-band dendrometers were used to measure within-season tree growth at three sites (dry, mesic, and wet) in the Big Thicket National Preserve, Texas to determine what affects within-season tree growth and if ...
Seasonal variation of metabolism and thyroid activity in the Mexican ground squirrel Citellus mexicanus
Metabolic measurements in thermal neutrality for the Mexican ground squirrel, Citellus mexicanus, in-dicated a mean summer metabolism of 1.10± .08 cc 02/gm/hr and a mean winter metabolism of .56±.08 cc 02/gm/hr. Animals ...
Grooming, aggression, and genetic relatedness in Parachartergus colobopterus, a neotropical swarm-founding wasp
I examined biting, grooming, and inspection behavior in a pre-emergent colony of Parachartergus colobopterus, a neotropical swarm-founding wasp, to determine whether kin discrimination occurs between adult colony members. ...
