The Emerald Ash Borer (EAB) is a wood-boring beetle native to Asia that now infests and kills ash trees (Fraxinus spp.) in North America. Many ecological communities will be dramatically altered by the mortality of ash trees caused by this invasive insect. The EAB recently colonized Point Pelee National Park of Canada in extreme southwestern Ontario, Canada, a site famous for its unusual plant and animal diversity as well as its extraordinary bird migrations. We conducted a census of breeding birds in two ash-rich mature forests at Point Pelee in order to obtain baseline data on the breeding bird communities prior to changes in forest communities that are likely to be caused by the EAB. Here we report the results of the bird census and review possible changes to the breeding bird fauna of Point Pelee that may result from ash tree mortality and the associated disruption of forest communities.

Small Mammal Species

Within-habitat distributions of common rodent species in two temperate-zone small mammal faunas were analyzed by a series of interaction tests to evaluate the hypothesis that the distribution and abundance of these animals is determined by competitive interference for space. In the Rocky Mountains of Alberta, Peromyscus maniculatus and Clethrionomys gapperi were independently distributed and there was no consistent relationship between the densities of the two species over a broad range of habitats. At Point Pelee National Park in Ontario, Peromyscus leucopus and Microtus pennsylvanicus distributions were also independent of one another, and again there was no relationship between the densities of these rodents across habitats. These field tests favour rejection of the hypothesis of competitive interference for space among temperate-zone small mammal species.

Surprising Fact

AbstractTrialeurodes abutiloneus (Haldeman) (Hemiptera: Aleyrodidae) is known to have been present in Canada since 1973. Despite this, the species has until now not been officially recorded; a surprising fact considering the close association of the species with economically important crops. The historic distribution expands from Mexico to southern New York and Michigan in the United States of America. In 2016, all life stages of T. abutiloneus were collected again on soybean (Glycine max (Linnaeus) Merrill; Fabaceae) plants grown in research greenhouses in southwestern Ontario, Canada. Specimens were morphologically and genetically identified to confirm their identity as T. abutiloneus. Thereafter, the barcode sequence for this species was also identified from the barcode of life data system, informing on the prior detection of this species from specimens collected at Point Pelee National Park, Ontario, Canada in 2012 during a barcode of life collection. Although this species is not considered a major pest on crops in Canada, it is related to other common pests within the same genus and can potentially transmit similar plant diseases. We provide the barcode COI sequence for the species, give an overview of the documented host range pertinent to Canada, and provide information concerning its natural enemies.

Toxorhynchites Rutilus

AbstractThe mosquito Toxorhynchites rutilus septentrionalis (Dyar and Knab) is recorded for the first time in Canada. The species was found breeding in a water-filled rot cavity in a tree in the deciduous forest of Point Pelee National Park. The distribution of the species for which this record represents an extension of the range is discussed.
