For the Oranges of Sargodha District: Pakistan, Podcasts and Environmental Policy Work with Living on Earth

Throughout my childhood, oranges had been the quintessential winter fruit in my village in Pakistan. The lure of the brilliant orange, the sweet and seizing taste, etched in my memory of mornings spent under the gentle winter sun, feasting on kinnow, mausami and red blood oranges. 

But the fertile soil we took pride in was plagued by rising water tables and soil concentrations. Though these fluctuations are commonplace, the looming threat of climate change offers no respite. Having grown up watching the back-breaking perseverance of farmers in a country which will incur major losses of arable land, I fear a future in which oranges and our staple crops will become as scarce as they are in dystopian stories.

Washed Away: “Freedom Hill” Explores Flooding Caused by Environmental Racism

Growing up in eastern North Carolina, Resita Cox didn’t understand why her town would flood on a regular basis. She had certainly never heard the term ‘environmental racism’ or ‘racial topography.’ 

It wasn’t until years later, when she was covering a story as a television journalist, that she began to understand the context of why her town, and other towns like it, were at a high risk of flooding and denied the resources to combat it. 

In 2016, she covered flooding that occurred in the wake of Hurricane Matthew in Princeville, North Carolina. She saw the signs that declared the town as the very first in the United States that was chartered by Black Americans. Seeing the lack of urgency to prevent the flooding that was happening here, in such an important landmark for Black History, she began to understand why it was happening in her hometown and others that didn’t have the same historical significance.

Illustrating the Importance of Women in Science

In the library’s McLean Wolf Rare Book Room you’ll find no shortage of works authored by men because, according to conventions of the time, they were best suited to explore the mysteries of the natural world. Some women, however, found ways bend expectations of womanhood to incorporate the study of the natural world into their lives. Many were born into families with the resources to provide them a formal education, of which drawing and appreciation for the natural world were a significant part. Some had access to scientific networks, who married or were related to male naturalists and were expected to support their work. Some were born into artisan families and incorporated their love for nature into their work. In the Academy’s Library and Archives, there are many examples of the important contributions of women.

Updated USDA Plant Hardiness Zone Map Spotlights Changing City

In the coming years, Philadelphia gardeners may try out some new plants and retire old favorites after an updated government map was released this fall. The USDA Plant Hardiness Zone Map gives gardeners a sense of which plants can grow in their region and which aren’t likely to make it through the winter. In this newest update, many Philadelphia residents have moved into a warmer half zone, reflecting changing environmental realities.

Natural history collections, like those at the Academy of Natural Sciences, help us understand these changes.

The Unexpected Diversity of Philadelphia’s Bees

While Philadelphia may not seem like an ideal habitat for wildlife, the city and county actually have a variety of green spaces, such as the John Heinz National Wildlife Refuge at Tinicum, the United States’ first urban wildlife refuge, to support plenty of different plant and animal species — including bees. But how many different kinds of bees call this city home? We reached out to Drexel University student and Academy co-op Liz Otruba to discuss what the bee population at the refuge really looks like.

Studying New Hawk Communities Through Genetics and Collection

Ornithologists carefully and strategically collect samples for the Academy’s collections from all over the world; work that often involves support from conservation organizations and even local community members. Every part of the specimen, big or small, will help tell the story of the bird’s species — its place in the family tree, their particular eating habits and hosted parasites, the health and ecology of their habitat and even changes in the region’s biodiversity over time. 

We reached out to Therese Catanach, PhD, a postdoctoral researcher in Ornithology who primarily studies hawks and their parasitic lice, but also analyzes genetic data for other researchers studying birds, insects and viruses, to learn more about the importance of the collection for genetics and discoveries, especially for hawks.

Highlighting Biodiversity: Freshwater Fishes in Equatorial Guinea

With dense canopies, soaring mountains and bubbling streams, Equatorial Guinea is composed of two wonderfully biodiversity-rich locations — the mainland Río Muni on the west coast of Central Africa and its islands, Bioko and Annobón.  A long chain of volcanoes extends southwest from the mountains in continental Cameroon into the Gulf of Guinea, where it gives rise to the islands of Bioko, Príncipe, São Tomé and Annobón. Bioko is actually much closer to Cameroon than the continental part of Equatorial Guinea.

Bioko has tropical monsoon climate that provides plenty of freshwater to its many streams. These streams are home to two types of fishes: those that live along coastlines and commonly move upriver into freshwater (amphidromous fishes); and those that are restricted to freshwater (continental fishes).

Highlighting Biodiversity: Searching for Snails in the Delaware River

Free-flowing for nearly 300 miles across four states — New York, Pennsylvania, Delaware and New Jersey — the massive Delaware River is the lifeblood of the Northeast, providing not only drinking water for over 15 million people, but also critical freshwater habitat for countless aquatic and riparian wildlife species. 

There are over 200 tributary streams and creeks comprising an estimated 14,057 miles of sheer waterway in the Delaware River watershed. Each one of these creeks and streams is connected to the river and nearby land, both through their shared waters as well as with their shared ecosystems. Human actions in one creek can impact another stream; native and invasive species can be carried upstream or down. In other words, the health of the whole system is reliant on the care and understanding of its many parts and players.  

As the watershed lands surrounding this river are still about half forested (with 18% agricultural and 14% developed), benchmarking the diversity found here is crucial to creating a holistic picture of the health of this most important waterway — for the present and for the future.

Highlighting Biodiversity: Familiar Flora in Newfoundland and Labrador

A botanist, a paleontologist, an architect and a retired lawyer planned a science trip to Newfoundland and Labrador. Armed with guidebooks, local floras and “The Shipping News,” the Pulitzer-prize winning novel by E. Annie Proulx, the trip’s botanist and the Academy’s Collection Manager for Botany, Chelsea Smith, PhD, was looking forward to investigating the plants of this Canadian province, as well as escaping the heat of July in Philadelphia.

What she found were the kindest people she’d ever met, surprisingly familiar plant species and — strangely — no moose.

There Is a Fungus Among Us! Killer Fungi in the Flesh at the Academy

Deep in the recesses of the Academy lurk the specimens of a very particular, silent foe — for insects, that is. Cordyceps and Ophiocordyceps are members of a group of parasitic fungi with otherworldly growth traits that have long been the inspiration for science fiction, now popularized across the nation. 

This type of fungus is ubiquitous; it is found all over the world, usually in the forest understories of warm tropical climates. There are thousands of different species of entomopathogenic fungi — species that attack living insects as their hosts. They float around in their spore stage, and most have generally evolved alongside the insects that are available within their environment, creating hosts out of ants, caterpillars and many unsuspecting others.

 Highlighting Biodiversity: Finding Frogs in the New Jersey Pine Barrens

Ron Smith, an instructor with Drexel University’s Department of Biodiversity, Earth and Environmental Science, and his group of volunteer community scientists were lured deep in into the swampy thicket of Wharton State Forest in the New Jersey Pine Barrens on the search for biological treasure. 

Their first clue was the sound of nasal quonking. They tied a yellow bandana high up on a tree branch to mark the location of where they would leave the trail and enter the dense vegetation toward a pond they could not yet see. Stealth was not their style; the noise of a few large human mammals negotiating the undergrowth of inkberry and sweet pepperbush was enough to quiet every creature in the wet woods. And the increasing presence of sphagnum moss on the forest floor had every footfall puddle water around their feet as they squished forward.

Highlighting Biodiversity: Spectacular Birds and the Amazon River

Few places are as evocative of biodiversity as the Amazon Rainforest, a region of South America that occupies just 0.5% of Earth’s terrestrial area yet harbors a disproportionately astounding 10% of known species diversity. Roughly 1,300 bird species call the Amazon Rainforest their home, as do more than 3,000 species of fishes and countless primates, butterflies, orchids, frogs and more.   

In some locations, the Amazon Rainforest is one of the last remaining truly wild places, with only minimal signs of the industrialized world — though this is rapidly changing. How the Amazon accumulated this impressive list of organisms remains one of the great mysteries of modern biology, one that continues to be debated by scientists who work across many disciplines. 

The region also has a major impact on the rest of the planet. By some estimates, the Amazon Rainforest contains as many as 13% of all the individual trees on the planet — making it one of Earth’s most crucial carbon sinks. Its vegetation stores a mind-boggling 120 billion metric tons of carbon in its stems, leaves, trunks and branches — a reduction, however, from what it has historically stored — but still a truly impressive number. Moreover, studies have shown that the Amazon Rainforest creates its own climate, which can then affect those of other regions as far away as the North American Pacific Northwest.

Leave the Leaves for Understory Habitats

Red, orange, yellow, gold, brown – every autumn, the canopies of the Northeast transform into a picturesque glory of color. Once they fall though, our opinions of these very same leaves may quickly change. Are they yard waste, an annoying nuisance to be cleaned up or something quite different and much more important? 

Leaves are actually critically important to the health of your yard. The simplest thing you can do to help support sustainable natural ecosystems in your area is to leave the fallen leaves on the ground during autumn.

Orchids: The Royal Family of Plants

Orchids are one of the most well-documented flowering plants in history. The earliest recorded European attempt at growing orchids was when Dutch botanist Paul Herma began documenting his cultivation of a North American orchid in 1698. While his attempt was not successful, it opened the door for many European botanists to try their hand at natural and artificial orchid reproduction.   

The first successful artificial orchid reproduction occurred in 1856 with the Calanthe Dominyi. The Calanthe genus has since welcomed many additions to the group such as Calanthe Triplicata and Calanthe Sylvatica. These orchids are best known for being a winter sprouting flower with deep roots.

Confronting the Effects of Coastal Climate Change

Environmental science major Kris Freyland sees the effects of climate change up close. Throughout their co-op this spring and summer, Freyland worked with Beth Watson, PhD, associate professor of biodiversity, earth and environmental science and senior scientist at the Academy of Natural Sciences’ Patrick Center for Environmental Research, to study the impact of saltwater intrusion into coastal forests.

“The forest is dying off, giving rise to ghost forests, and salinity and soil flooding is leading to more bare ground, wetlands or open water,” Watson explained. Ecohydrology, the study of the interactions between water and ecosystems, allows the research team to analyze the way the landscape has changed and predict how it might continue to erode in the future.

Across the setting sun, migrating birds fly high in the sky toward a distant destination. It’s an iconic image we’re all familiar with, heralding the arrival of autumn. Many well-known species of birds migrate night and day between August and November, including hawks, geese, thrushes, warblers and sparrows. As these birds journey through the darkness, however, they often face unexpected, dangerous and unseen challenges — distracting bright lights, invisible glass windows and human-made buildings.

The Future Ghost Forests of New Jersey

Jakes Landing is a centuries-old access point to Dennis Creek in Cape May, New Jersey, where the forest landscape abruptly drops into a tidal saltwater marsh. Close to the marsh, row after row of dead Atlantic white cedars jut out of the ground like spikes. Just beyond those are swaths of statuesque loblolly pines.

The forest is healthy now, but these trees are in danger. Most trees in the Delaware Estuary region that stand close to salt marshes are at risk of death due to sea-level rise.

Coyote and Fox Populations on the Rise?

You may have noticed a common theme at the dinner table: Grandpa has spotted the fox in the yard again or perhaps your aunt has heard of a coyote in the local nature preserve. These discussions usually lead to a general wonder of whether wild canine populations are on the rise, if they are a positive or negative influence on the local environment and what their presence might mean for the neighborhood. 

The Academy wanted to know these answers, too. So, we reached out to Dane Ward, PhD, assistant teaching professor in Drexel’s Biodiversity, Earth and Environmental Science (BEES) department who specializes in urban wildlife ecology, to learn more.

Reading the Leaves

The veins in a leaf do more than store water for the plant; even plant leaves preserved as fossils. They can reveal what environmental conditions were like when and where the plant was growing.

Leaf veins are a passion for Zack Quirk, a National Science Foundation fellow and University of Michigan paleobotany PhD candidate, who’s been using the Academy’s Botany Collection to measure the length of veins in plants. He chose the Academy herbarium because of it wide range of specimens collected from around the world. To collect these plants on his own would be prohibitively expensive and time-consuming.

A Real Shocking Discovery

Academy Ichthyologist Mark Sabaj is one of the co-authors on the descriptions of two new species of electric eel.  

Scientists have discovered a new species of eel that can discharge up to 860 volts of electricity – significantly more than the 650 volts previously recorded by what had been believed to be the only type of eel in existence… until now.

Mark Sabaj, PhD, interim curator of fishes at the Academy of Natural Sciences of Drexel University is well-versed in techniques for catching electric eels both with and without getting shocked. He contributed to a large study of electric eels as a member of a multinational team led by Carlos David de Santana, an ichthyologist at the National Museum of Natural History in Washington, D.C. Sabaj is a co-author on the descriptions of two new species, Electrophorus voltai and Electrophorus varii, published in Nature Communications.

Four Ways to Cut Your Carbon

Looking to reduce your personal carbon emissions? There are some big steps you can take. For example, if you need to travel a long distance, you can choose rail or even sailboat — to follow in Greta Thunberg’s wake — rather than flying. The 16-year-old Swedish climate activist last week completed a transatlantic journey by racing yacht to attend the United Nations summit meeting on global warming this month. Few of us fly every day, and fewer sail. So how can we do our part to reduce CO2 emissions (which contribute to harmful greenhouse gases largely blamed for driving global warming) in our daily life?
