GRAPH­ING THE GUANO

Re­searchers from Queen’s Univer­sity, the Univer­sity of Ot­tawa and Me­mo­rial Univer­sity of New­found­land used a novel method­ol­ogy to bet­ter un­der­stand how pop­u­la­tions of Leach’s storm-pe­trels (Ocean­odroma

leu­corhoa) have changed over the cen­turies on a small is­land off New­found­land. In a new pa­per, the team de­scribes delv­ing into lake sed­i­ments to track 1,700 years of fe­cal mat­ter. Their method may of­fer other re­searchers a way to get long-term data on bird pop­u­la­tions.

WOLVER­INES VS. ODDBALLS

“Od­dball” is the nick­name of a mys­te­ri­ous new par­a­sitic worm (Trichinell­a chan­chalen­sis) that seems to be re­lated to a de­cline in north­ern Cana­dian wolver­ine pop­u­la­tions. Re­searchers at the Univer­sity of Saskatchew­an have noted that the worm’s range is lim­ited to the ar­eas in which wolver­ines are de­clin­ing. They are search­ing for the link.
