About this Dataset

Thermal Tolerance Of Atta Cephalotes

Thermal Tolerance of Atta cephalotes

Temperature and Physiology Across Rain Shadow Sites

About this dataset

This dataset contains data collected from three distinct locations in Costa Rica that experience different temperature regimens due to the impacts of rain shadows. We are specifically interested in the upper thermal tolerances of workers of the leaf-cutting ant species Atta cephalotes and how they respond to a range of temperatures. The included measurements comprise head widths and corresponding CTmax temperatures, as well as day-to-day temperature readings gathered from ibuttons that were distributed at each site. Our dataset offers insight into not only how these workers adapt to changing climates but also how other species may be affected by gradual climate change. Using this information, we can explore new strategies for conserving species and mitigating issues related to global climate change

How to use the dataset

This dataset contains data on the upper thermal tolerances of Atta cephalotes workers in response to temperature extremes in Costa Rica. It helps researchers analyze the effects of different temperature regimens on ant physiology.

To use this dataset effectively, one should first understand its columns and variables. A comprehensive list of these is provided above. As a general guide, Year and Site are used to identify each observation; Log_CTmax and CTmax indicate the maximum critical thermal maximum for each worker; ibutton_Min, ibutton_Max, and ibutton_Avg measure the minimum, maximum, and average temperatures from an ibutton; and various columns such as “BC_MAT” measure climate-related conditions such as annual mean temperature or precipitation seasonality at each site.

To start using this dataset, select a specific “Year” or “Site” in which you would like to further study ant physiology at different temperature regimens. Then narrow down your selection by looking at variables such as “Night Warming Tolerance” or “Mean Warming Tolerance” which specify how ants respond to warming events with respect to their environment (e.g., annual mean temperature). Lastly, compare these responses with those found in columns measuring day-to-day temperatures (e.g., AvgTemp) or head widths (e.g., Log CTmax) for further comparison between teams living under particular conditions where thermal limits could be broken due to climate change events resulting from anthropogenic activities..

Once you have selected appropriate criteria for your analysis – year/site/thermal tolerance measures -- navigate through different pages within our Kaggle platform by clicking on tabs that are related to your research question: Download Data tab includes information relating directly to physiological measurements within Atta workers over time To Summarize tab provides summary statistics associated with differences between sites To Historic Graphs tab visualizes temporal patterns across various levels of physiological measurements Choose a section that best answers your research questions!

Research Ideas

Studying the influence of elevation and climate variables in predicting thermal tolerances at different sites by using regression modeling techniques to identify how different climate variables predict CTmax in Atta cephalotes workers across the studied sites.

Analyzing ibutton temperatures at different transects throughout a site to assess average daily weather patterns in order to understand how these contribute to local species variation within a geographic area as it relates to their physiology and behavior
