"In 2011, botanists from The Field Museum, together with colleagues from all over the world and local Fijians, spent several weeks looking for Bryophytes in Fiji. Join them in their expedition and learn what this fascinating group of early land plants can tell us."
Eve Emshwiller's insight:
Field Museum botanists Matt von Konrat, Thorsten Lumbsch, and others study the bryophytes and lichens of Fiji.
Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to two millennia. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. At multi-decadal to centennial scales, temperature variability shows distinctly different regional patterns, with more similarity within each hemisphere than between them. There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between ad 1580 and 1880, punctuated in some regions by warm decades during the eighteenth century. The transition to these colder conditions occurred earlier in the Arctic, Europe and Asia than in North America or the Southern Hemisphere regions. Recent warming reversed the long-term cooling; during the period ad 1971–2000, the area-weighted average reconstructed temperature was higher than any other time in nearly 1,400 years.

Beekeepers and researchers nationally are reporting growing evidence that a powerful new class of pesticides may be killing off bumblebees. Now, research points toward another potential cause: metal pollution from aluminum and nickel.
A mismatch between the departure schedules of songbirds and higher spring temperatures at their breeding sites means they are arriving 'late' for the advanced spring and likely missing out on peak food they need to be productive breeders.
Aerial insectivores, like purple martins and other swallows, are experiencing strong population declines, particularly species migrating longer distances and populations breeding further north. Scientists have shown in a European species that declines may be due to an inability to advance arrival schedules to match a warming climate. This study provides the first direct evidence of a discrepancy between higher spring temperatures at breeding sites and departure schedules of individual songbirds..... http://www.sciencedaily.com/releases/2013/06/130603135525.htm
Big ecosystem changes viewed through the lens of tiny carnivorous plants Science Daily (press release) The water-filled pool within a pitcher plant, it turns out, is a tiny ecosystem whose inner workings are similar to those of a full-scale water...

"What do a pond or a lake and a carnivorous pitcher plant have in common?" Use of pitcher plants to study tipping points, such as those from climate change.
Here's a good rule, which I learned from a copyright lawyer, "The golden rule: Just because it’s on the internet doesn’t give your permission to reuse it."
With that in mind, are you doing enough to teach your students about the appropriate appropriation of images? Of course, you teach them how to find and cite articles, but what messages do you give them about crediting image souces?
Talk to your students about the importance of crediting the work of others. Written class work or talks that are shared only in the classroom should cite all image sources. Work that is to be published, whether in a journal or online, needs a more formal approach, which often includes getting permission from the copyright holder.
Here are a couple of tips about sourcing images for publication that I shared at a science communication workshop.
If you want to reuse an image from an image database, be sure to adhere to their requests – some want you to write for permission, others do not. I always include a credit and a link to the source – it’s polite, and gives credit where credit is due.
A few that are good sources of (usually) free images, with attribution:
Images from scientific journals are copyright protected. You can often use them for educational purposes without paying a fee, but you must obtain permission first. Look for the Rights and Permissions link, usually on the abstract page of an article, but sometimes on the general journal information pages. Many journals use the Copyright Clearance Center service to manage their permissions - you have to register. Some journals cover all their content by a Creative Commons license and do not require a copyright clearance center request (but do require attribution). Notably, JBC and the PLOS and BMC journals are covered by creative commons licenses.
I wasn't taught about the electronic sharing of images when I was a student, because we didn't have the internet (as we know it) when I was a student, but our students live in in a more complex world - don't send them out unprepared!
