The impact of a fungus-feeding nematode (Aphelenchoides sp.) on decomposition of trembling aspen wood by various wood-decay fungi
(2018)Grazing by fungus feeding invertebrates on fungal mycelium can potentially impact many important ecological processes such as the formation of mycorrhizas and the decomposition of wood and litter. A study was initiated to ... -
The impact of climate change on the phenology of short- and long-distance migratory birds
(2021)Quickly changing temperatures due to climate change are expected to have devastating consequences on the migratory bird populations around the globe. However, surprisingly, several studies have demonstrated that some ... -
The impact of environmental and ecological construction on the sustainable development of cities: a case study of Nanjing, Jiangsu Province, China

The impacts unnatural foods have on hibernation and health in American Black Bears
(2021)As humans encroach more and more into wild spaces, we will continue to see an increase in the negative impacts our lives have on those of the animals we share these spaces with. One of these ways is through our food. In ... -
Implementing a tree pruning cycle into the city of Thunder Bay
(2021)Several cities in Ontario and across Canada were contacted regarding their tree pruning programs. Of the ten from Ontario that responded, seven had a cyclical tree pruning program. Annual budgets ranged from $50,000 up ... -
The importance of container material in stored water quality
(2022)Water is one of the primary resources to sustain human life. The quality of good water and air are important factors to protect human health and the environment. The impact of container material on stored water quality ... -
Increasing diameter growth content of red pine (Pinus Resinosa) through intensive management
(2017)Intensive forest management can only be justified if it increases wood quality or yield sufficiently to compensate for the additional investment. Treatments such as thinning and/or pruning are typically only applied to ... -
