The purpose of this resource is to observe budburst on selected trees at a Land Cover or Phenology Site. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, food availability, seasonality, photoperiod (day length), and other environmental factors. (less)

Students are presented with a graph of atmospheric becomes CO² values from Mauna Loa Observatory, and are asked to explore the data by creating a trend line using the linear equation, and then use the equation to predict future becomes CO² levels. Students are asked to describe qualitatively what they have determined mathematically, and suggest reasons for the patterns they observe in the data. A clue to the reason for the data patterning can be deduced by students by following up this activity with the resource, Seasonal Vegetation Changes. The data graph and a student worksheet is included with this activity. This is an activity from Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site. (less)

Climate Change and Bark Beetles of the Western United States and Canada: Direct and Indirect Effects

Climate Change and Bark Beetles of the Western United States and Canada: Direct and Indirect Effects

Climatic changes are predicted to significantly affect the frequency and severity of ... (more)

Climatic changes are predicted to significantly affect the frequency and severity of disturbances that shape forest ecosystems. We provide a synthesis of climate change effects on native bark beetles, important mortality agents of conifers in western North America. Because of differences in temperature-dependent life-history strategies, including cold-induced mortality and developmental timing, responses to warming will differ among and within bark beetle species. The success of bark beetle populations will also be influenced indirectly by the effects of climate on community associates and host-tree vigor, although little information is available to quantify these relationships. We used available population models and climate forecasts to explore the responses of two eruptive bark beetle species. Based on projected warming, increases in thermal regimes conducive to population success are predicted for Dendroctonus rufipennis (Kirby) and Dendroctonus ponderosae Hopkins, although there is considerable spatial and temporal variability. These predictions from population models suggest a movement of temperature suitability to higher latitudes and elevations and identify regions with a high potential for bark beetle outbreaks and associated tree mortality in the coming century.

In this TIEE dataset, students address the question of how global global temperatures change during the 21st century, and how these changes vary geographically, seasonally, and depending upon future human activities. Students consider how to detect trends in large data sets against a background of variation. They use output from global climate models to examine projected climate change during the 21st century under a range of greenhouse gas emissions scenarios. (less)

The purpose of this resource is to observe seasonal migration patterns, feeding habits, and nesting behavior of Ruby-throated Hummingbirds (Archilochus colubris) in North and Central America. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, food availability, seasonality, photoperiod (day length), and other environmental factors. (less)

PLANT BIOLOGY: Flower Arranging in Arabidopsis

Access to the article is free, however registration and sign-in are required. The flowering of plants in response to changes in day length and temperature is controlled by three intricate signaling pathways. In this Perspective, Devlin and Kay examine new research (Samach et al.) that shows how signals from the three pathways converge on the promoters of several key genes to bring about flowering in the model plant Arabidopsis.
