Study: Bumble bees lacking high-quality habitat have higher pathogen loads

Bumble bees found in low-quality landscapes—characterized by a relative lack of spring flowers and quality nesting habitat—had higher levels of disease pathogens, as did bumble bees in areas with higher numbers of managed ...
