Blog Post #3: Ongoing Field Observations
Focus of Study:
Continuing my field research project, I remain focused on the sweet chestnut (Castanea sativa) tree situated in my backyard. This tree serves as the focal point of my study, offering insights into the interactions between flora, fauna, and environmental conditions.
Field Journal Observations:
On February 7th, 2024, amid a wintry landscape with lingering snow and varied precipitation, I conducted further observations of the sweet chestnut tree and its surroundings. Here are the noteworthy findings recorded in my field journal:
- Location and Environmental Gradient:
Situated on the slope of a mountain in Vernon, BC (coordinates: 50.2590913,-119.2552557), my backyard spans approximately 30 feet by 45 feet. The chestnut tree stands at the far end, flanked by grass and a sprawling grapevine. The terrain gradually slopes downwards, creating microclimate variations across the yard. - Comparison with Park Chestnut Tree:
In addition to observing the chestnut tree in my backyard, I plan to compare its characteristics and ecological interactions with another chestnut tree located in the expansive park in front of my house. This park, spanning over 2km in width and 1km in length, attracts park-goers and hosts various activities such as baseball games due to the nearby baseball field. - Observation Questions:
- A recurring flock of birds frequently congregates around the chestnut tree, irrespective of the season. I aim to investigate the factors driving this behaviour and explore whether it correlates with specific environmental conditions.
- The chestnut tree emits a distinctive scent, noticeable in its leaves and branches. I intend to monitor the development of this scent over the changing seasons to understand its correlation with environmental cues.
- Deer are common visitors to our yard, but their attraction to specific vegetation features, such as the chestnut tree, remains uncertain. I aim to examine the preferences of deer and their relationship with various elements of the backyard ecosystem.
Hypothesis and Prediction:
Based on these observations, I formulate the following hypothesis and prediction:
Hypothesis: The distribution and behaviour of wildlife, including birds and deer, around the sweet chestnut trees are influenced by microclimate variations, vegetation characteristics, and human activity levels.
Prediction: I anticipate that wildlife activity will vary between the backyard and park settings, with factors such as human presence and recreational activities influencing bird and deer behaviour. Additionally, differences in microclimate and vegetation composition between the two locations may contribute to observed variations in ecological interactions.
Variables:
- Response Variable: Wildlife Activity (Continuous variable)
- Explanatory Variable: Microclimate, Vegetation Characteristics, Human Activity Levels (All continuous variables)
Through systematic observation and analysis, I aim to unravel the ecological dynamics of chestnut tree ecosystems across urban environments, shedding light on the intricate relationships between organisms and their surroundings.
You need more than 2 replicates, I am not clear how you will have a hypothesis about wildlife activity and chestnut trees without multiple replicates in areas with and without chestnut trees.
