Unleashed dog attacks and injures goats at the Arboretum
September 29, 2016 Arnold Arboretum
Two of four goats leased by the Arnold Arboretum for weed and invasive plant control in its Peters Hill landscape were attacked by an off-leash dog that jumped over their electric fence enclosure Wednesday afternoon. This unfortunate and violent incident illustrates the potential dangers caused by dog owners who allow their animals to roam off-leash at the Arboretum, a violation of city and state law as well as park regulations. The Arboretum requests the public's help in ensuring the safety of all by keeping dogs leashed at all times in the Arboretum landscape. Please report any off-leash pets to Boston Animal Control (617.635.5348) or Boston Police (617.343.5630).

September 25, 2016 Arnold Arboretum
In addition to finding, mapping, and collecting Stewartia, we collected seed from 10 taxa from the Arnold Arboretum’s Campaign for Living Collections. It was literally a fruitful trip, and one characterized by kind collaboration, beautiful forests and landscapes, and venomous snake sightings.

Bumblebee behavior
September 23, 2016 Research News
Some flowers release pollen out of small pores in the anthers. Bumblebees (Bombus impatiens Cresson) coax this pollen out by vibrating their bodies (buzz pollination or sonication). In research published in Apidologie, Callin Switzer and colleagues observed bumblebees in the urban environment of the Arboretum, the rural environment of the Concord Field Station and in the greenhouse. They found that they alter their sonication behavior depending on which plants they visit and the environmental conditions. abstract »
