Merry Christmas and Happy Hanukkah everyone! For today’s weird and wonderful focus, I have decided to write about a large, hoofed creature: elk! I know, I know, I probably should have written about reindeer, but elk are really cool too, and North Carolina is home to a growing population of them! Also called Wapiti, which is a Shawnee word meaning “white deer”, elk once roamed throughout what is now the continental U.S., including the mountains of Western North Carolina and perhaps even the northwestern piedmont region of the state. During the 1800s elk became extirpated from most of the country east of the Rocky Mountains, mainly due to hunting pressure and habitat loss. Today, the largest populations are out in the western half of the U.S., but there are a few small populations in the eastern half, including the one in Great Smoky Mountain National Park. 

There are a few subspecies of elk: the Rocky Mountain Elk is probably the most widely known, with its pale, cream-colored body (hence the name “Wapiti”) and dark head, neck, and legs. The Roosevelt Elk, named after Theodore Roosevelt, the 26^th President of the United States, is found in the Pacific Northwest; the population in North Carolina is the Manitoban subspecies, Cervus elaphus manitobensis, as the Eastern Elk species, Cervus elaphus canadensis, is extinct. This subspecies has a dark head, neck, and dark legs, with the body ranging in color from deep copper to light tan or beige. While they are sometimes mistaken for white-tailed deer, they are much larger, measuring about five feet high at the shoulder for a full-grown bull elk and weighing around 700 pounds. It surpasses the black bear in size and is the largest mammal in our state.

A bull elk can have harems of up to 60 cows, making this species the most polygamous of all the deer species in North America. Bulls will sound a bugle call to warn competing males to stay away, and to assert their dominance over the cows in their harem. This call begins as a bellow, transitions to a whistle or a noise described as a scream, and ends with a series of grunts; the whistle or scream portion is what carries over long distances. Both bulls and cows will mark their territory by stripping the bark from seedlings, and during the breeding season, bulls will dig wallows. Wallows are depressions in the ground that they make with their hooves and antlers, into which they urinate and defecate to create a strong odor. Bulls will roll in the resulting, stinky mud, which is either a way to attract cows, a way to intimidate other bulls, or may serve both purposes. Either way, I feel confident in listing this species as one of the weird and wonderful animals that call our state home.

There have been a handful of attempts to reintroduce elk into North Carolina: the first attempts, during the first half of the 20^th century, failed. However, the project was initiated again in 2001 by the National Park Service, with 52 individuals of the Manitoban subspecies introduced over a period of two years into the Cataloochee Valley region of the Great Smoky Mountain National Park. Some of the elk wandered outside of the park’s boundaries and established populations in neighboring counties. The NPS is responsible for the elk within the park, and the North Carolina Wildlife Resources Commission manages all of the populations outside of the park’s boundaries. Today it is estimated that around 200 elk are living within the state on national, state, local, and privately held land. So, the next time you take a road trip through Great Smoky Mountain National Park, consider driving along the road through Cataloochee Valley. From your vehicle you may be fortunate enough to see some members of this weird and wonderful species amongst the trees or in the fields. During late September through early October, you may even be able to hear the famous elk bugle call. Alternatively, consider stopping by the North Carolina Zoo: amongst their animal residents, which are over one thousand creatures and counting, is an elk herd. In whatever form you choose to view this impressive species, take some time to appreciate its resilience, beauty, and yes, its dash of weirdness. 

Many gardeners out there are entering their busy season, as fall is the perfect time to install new vegetation in gardens and natural landscapes. Utilizing species native to a particular area and making sure they are the appropriate ecotype of that species is increasing in popularity amongst gardeners. Native plant gardens tend to exhibit large and/or colorful species of flowers, shrubs, and vines, while overlooking some of the less-flashy plants present in our state. One such North Carolina plant is Hexastylis arifolia, otherwise known as the little brown jug. This low-to-the-ground herbaceous perennial is often overlooked on woodland hikes, as the flowers are not particularly eye-catching. Those that notice it may confuse this species with wild ginger, Asarum canadense, which is in the same family, but has deciduous leaves, whereas little brown jug is an evergreen.

Little brown jug has triangular to arrow-shaped leaves that are leathery in texture and release a spicy odor when torn. This species was used as a ginger substitute by early settlers, and local indigenous tribes used extracts and infusions from the leaves and roots to treat respiratory ailments and heart problems. This plant gets its name from its flowers, which are jugs often hidden beneath the leaf litter due to their short stems and rhizomes. These small, urn-shaped flowers grow to be about an inch long, are in bloom from March through May, and can be brown, green-brown, or purple-brown on the outside and a dark purple-brown on the inside. If the flowers are right at ground level, and they are not brightly colored, how is this species pollinated? Well, that is where the weirdness begins!

It was previously thought that both the Asarum genus and the Hexastylis genus were pollinated by carrion flies and fungus gnats. On the surface, this makes sense: the flowers of both genera are on the ground and are flesh-colored, matching the preferred foods of those groups of insects. However, research performed on wild ginger, Asarum canadense, since the 1980s has gathered evidence supporting the hypothesis that this species is self-pollinating. Fascinating information, you are probably thinking, but wasn’t this article about the little brown jug, and not its distant relative? Subsequent research on the Hexastylis genera has demonstrated that the distance between their anthers and stigmas in each flower is too great for self-pollination on their own. They need a little assistance, namely an insect one.

While wild ginger does not produce an odor, Hexastylis arifolia releases a very faint odor that resembles rotting flesh. Now, I have personally attempted to smell this odor on little brown jugs in the wild, and it is very hard to detect. You must get your nose at the right spot to smell the mild odor of decay. It is now thought that little brown jugs are pollinated by various species of carrion beetles. This group of beetle species spends its time on the forest floor searching for decaying flesh and poop in which to lay eggs; thus, the flowers of little brown jug would be easy to access. As these species excel at following scent trails to rotting refuse, they can easily locate these flowers. It is hypothesized that, once inside of the flower, the beetles move the pollen from the anther to the stigma while they scramble around, assisting the self-pollination process. So next spring, when you are taking a hike through a North Carolina forest, pay attention to the herbaceous plants along the forest floor. Chances are that the little brown jug is among them, waiting for a beetle to come along and pollinate one of their flowers. That, my friends, is one weird and wonderful plant! 

Last week we discussed Executive Order No. 305 and how that would, hopefully, lead to more wetland habitats being protected in North Carolina. The North Carolina Salt Marsh Action Plan, or NCSMAP, was briefly mentioned as a positive step forward in preserving, maintaining, and restoring the salt marshes along our state’s coast. Today we are going to delve into NCSMAP, which was released in May of this year. This action plan was initiated by the North Carolina Coastal Federation, or NCCF, as means of developing a guide for how the state could accomplish the goals set out in the South Atlantic Salt Marsh Initiative (SASMI) Plan, which was published in May of 2023. There are approximately 1 million acres of salt marsh in the South Atlantic region, which extends from North Carolina through Florida. This unique ecosystem provides habitat for over 75% of the species important in the fisheries industry, which in turn supports approximately 39,000 jobs. Salt marshes harbor other wildlife species, and, due to their ability to absorb large volumes of water, provide protection from flooding for the communities, military installations, and infrastructure present along the coast.

Despite the clear benefits to having salt marshes, this particular ecosystem is under threat from both sides. On the one side, they are under threat of being destroyed for development; on the other, they are at risk of dying off due to rising sea levels. While the vegetation within this ecosystem can tolerate inundation for long periods, they do require access to air at some point; salt marsh vegetation that is permanently submerged under the sea cannot survive. Thus, the SASMI Plan proposes adaptive measures that can help save this critical habitat, not only for the wildlife, flood control, and water filtration benefits, but for the benefit of the human populations that have called the area home for centuries. One such community is the Gullah/Geechee Nation, which was officially established in 2000 but has a rich history extending back to the 18th century. Their communities are spread along The Gullah Geechee National Heritage Corridor, which stretches from Jacksonville, North Carolina to Jacksonville, Florida. The Gullah/Geechee people’s ancestors were slaves and freedmen who settled in the region, and in 1861 and 1862 they were able to purchase lots of land, ranging in size from 10 to 40 acres. Unfortunately, it is projected that about 25% of the land in this corridor, throughout all four states, will be flooded/inundated due to the rising sea levels.

The SASMI Plan states that tackling sea level rise is outside of their scope, but what is within their scope is determining methods for salt marsh protection and migration that can be implemented, with state and local needs in mind, to keep these 1 million acres intact. Now wait a minute, you may be thinking, did you just say “salt marsh migration“? Yes! One of the strategies that is being proposed is to ensure that salt marshes can shift inland as sea levels rise. If the conditions are right, salt marsh vegetation will migrate inland, or landward, to escape the rising water levels. For this to work there has to be space available into which the salt marsh can move; the slope cannot be too steep; and there cannot be any physical barriers, such as roads, hardened shorelines, and urban areas. The SASMI Plan stresses that, while there are large areas of low-lying inlands along the whole South Atlantic region where the salt marsh can thrive, the migration must be executed carefully in order to avoid impacts to abutting freshwater and estuarine ecosystems and cultural resources. For North Carolina specifically, lower elevations of the northern coastal region offer more potential marsh migration space than the higher elevations of the southern coastal region.

NCSMAP proposes three strategies to protecting the salt marsh ecosystem in the state. Strategy #1 is to preserve what salt marsh areas are already in existence, through conservation and restoration efforts. By minimizing impacts of landward stressors, promoting and advancing their restoration, protection, and conservation, expanding the usage of living shorelines, and facilitating salt marsh research, the salt marsh habitats currently in place will continue and be able to migrate. The second strategy is to facilitate this migration wherever possible through conserving migration corridors and researching and assessing potential areas for migration. In addition, making sure that salt marsh migration is a priority when it comes to infrastructure planning is critical for the survival of the salt marsh. Finally, incorporating crosscutting approaches is the third strategy. This involves more research, pursuing funding, encouraging policy and management adjustments, and, perhaps most importantly, taking the time to communicate, engage with, and educate target communities and audiences. Without public awareness and support, the conservation and protection of the salt marsh ecosystem in North Carolina, and the South Atlantic region as a whole, will not be very effective.

NCSMAP is a great start for protecting salt marsh wetlands in our state, but it is going to take some time before all of these strategies pick up speed. In the meantime, education and community outreach will be the best way to learn about the issues and determine the methods that work for people and nature. Recognizing this, the North Carolina Salt Marsh Steering Committee (SMSC) established a Stakeholder Advisory Panel, consisting of over 100 public and private stakeholders, to provide guidance and feedback on how the actions proposed by SASMI and NCSMAP are doing in our state. By working together, the salt marsh habitats, and all of the natural and cultural resources they contain, can be preserved for years to come.

There are eleven lizard species that call North Carolina home. Well, thirteen, if you include the two introduced species, the Mediterranean gecko and the Texas horned lizard. This month’s weird and wonderful focus is on the Green Anole, Anolis carolinensis. This lizard ranges throughout the coastal plain, piedmont, and foothills of the state and can be green, brown, or green and brown in color. Many lizards found in the brown form have a lighter stripe that runs down their back, and a few individuals may even have a crest or ridgeline along their neck and back. Green anoles can be found on the ground, along fences, on structures, and even in trees, as they have sticky toe pads that help their grip.

Males of this species are highly territorial: when approached by a rival, a male green anole will extend his bright pink dewlap, or throat fan, and bob his head up and down. If that is not enough to frighten away the intruder, a fight may ensue. One male’s territory can be as small as 1 cubic meter, but it can overlap with the home ranges of 2 to 3 females, whom he courts by bobbing his head up and down. The sight of a male performing his head bobbing sets off a domino effect of physiological responses in the female, which eventually leads to her laying an egg, one at a time, throughout the spring and summer months. The eggs are laid in shallow depressions of sand, rotting wood, leaf litter, and other similar substrate; when the baby lizards hatch after 7 weeks, they are only around 2 ½ inches long. As the days shorten towards the end of summer, the reproductive organs of both the males and females become smaller in size. Adults and juveniles feast on small invertebrates, such as crickets, grasshoppers, and flies, but nectar has also been recorded as a source of food.

So…green anoles are like any other lizard in North Carolina? Wrong! Take another look at the first paragraph of this post, where it says, “Many lizards found in the brown form…” and mentioned that they can also come in the color green. Green anoles are weird and wonderful because they can change color from bright green to brown and vice versa! They are the only color-changing lizards that we have in our state. Their physiological color change is due to specialized cells called chromatophores. Chromatophores contain pigments and/or nanostructures that, when rearranged, result in a rapid color change. There are many different kinds of chromatophores: green anoles have melanophores, which contain organelles called melanosomes. Melanosomes exclusively hold melanin, and the ones present in dermal melanophores determine the color. Specifically, the larger an area (aka distribution) of melanosomes means more light is absorbed, resulting in a darker color being produced. Alright, so what triggers a green anole to decide to change from one color to another? That is less understood, though we know that temperature can affect how quickly chromatophores can rearrange their internal nanostructures and pigments. Thus, it has been hypothesized that these lizards change colors to control whether they absorb or reflect heat. It has also been suggested that they change color in response to social behavioral cues from other members of their species. Regardless, we North Carolinians are fortunate that these small jewels of the lizard world grace our state.
