Took this quiz again after #ees028 in the spring. I’ve improved about .1 Earths since May, still have a long way to go! #ees152

[Dave Jha @jha_dave]

I took this quiz a few weeks ago after we mentioned it in class, but I wanted to share it so that I can look back and hopefully make this number go down #ecologicalfootprint #ees028

Although our days in the forest are behind us, here are photos from once we first entered in summer and when we left in winter. Quite the difference! #ees152

Found an interesting research article about the commonness of rarity in plant species. It’s pretty interesting, especially in the correlations of climate change/human impact on these species. #ees152 https://t.co/YeOGbyzcTC

Drilling into the cores of Oaks to determine the age of the tree #ees152

An unorthodox way of using drones to learn more about population genetics! #ees152

[Journal of Ecology @JEcology]

Can we tell much about the genetics of a population just by looking at a landscape? New research suggests that we can!

@benjaminblonder explains how remote sensing can be used to measure population genetics in aspen trees

Look at all these invertebrates we collected from the river last week! #ees152

Exam 2 review sheet for #ees152 is now posted.

Sampling macroinvertebrates in the Lehigh Canal and the Monocacy Creek. We also accidentally caught a fish! 🎣 #ees152

[Dave Jha @jha_dave]

Beautiful day in the Experimental forest as we put some of the concepts we learned about population ecology into work. #ees152

[Dave Jha @jha_dave]

Profiling NJ Island Beach State Park. Amazing how species have adapted to the rigorous conditions, and how the variability of species will change in just a few meters #ees152

[LehighEcology @LehighEcology]

State of the Lehigh Experimental Forest. 2013-2019. It is a strange time to be a forest on South Mountain. #ees152

[Dave Jha @jha_dave]

@lennylaw @LehighEcology @PlantSnap I have not, didn’t know that they existed. going to give those apps a try and see how close it comes to old fashion observation

[Dave Jha @jha_dave]

When identifying trees, examining leaves can be a great aid to figure out the species of a tree. We found that some trees are high above the ground and identifying leaves can be tricky. Our smartphones we carry have amazing cameras, and we decided to use them! #ees152

[LehighEcology @LehighEcology]

Assessing the forest. #ees152

My uncle, the director of the Global Health Institute at Harvard, spoke about #ClimateChange from a health lens today in front of the Ways and Means Committee of Congress. He spoke to how policies can change in our country. #ees028 https://t.co/Dz37eaCeLF

Some more interesting stats I got:

[Sam Sausville @SSausville]

Like and/or retweet if you are taking EES 152 with @LehighEcology next semester as well. Looking forward to seeing familiar faces there #ees028

The United Kingdom can cut emissions to nearly zero by 2050. I think this is a great example of 'we’ll believe it when we see it' :) #ees028

From the National Geographic: Using studies of tree rings going back centuries, scientists have uncovered clear evidence that the rise of human-generated greenhouse gases was having an effect on global drought conditions as early as 1900. #ees028
