The northern map turtle, also known as a common map turtle, is aquatic. It got its name from the patterned markings on its shell. The markings look like contour lines on a topographical map. Commonly, map turtles have varying sizes.
A male northern map turtle weighs between 150g to 400g, while females weigh between 0.67kg to 2.5kg. Furthermore, a female’s carapace length grows up to 27cm while males stop growing at 16cm.
They like to stay in large bodies of water like ponds, rivers, and lakes. Northern map turtles are endemic to St. Lawrence River drainage basin areas around south Quebec and Ontario to northern Vermont, extending into the Great Lakes. You will also find it in the Susquehanna River system in Pennsylvania, Maryland, and the Delaware River.
Their strong jaws facilitate their flesh-eating nature. They feed on mollusks, insects, and crayfish. Females can easily crack open mollusks and snails because they have stronger jaws and wider heads.
Sadly, IUCN listed northern map turtles as endangered in Kansas, Kentucky, and Maryland.
The Ouachita map turtle is a medium-sized turtle with a rectangular or oval yellow patch behind its eyes. Male turtles grow to 6.5 inches, while female turtles grow to 10.5 inches in length. Their upper shell, also referred to as a carapace, is jagged. It is a mix of olive-green and brown, with yellow lines covering the top of the turtle shell, making it look like waterways on a map.
Their head, neck, and limbs are dark green with thin yellow lines. Ouachita turtles have a black horizontal slit in their bright yellow eyes.
They eat fish, shrimp, insects, and mollusks. They also feed on algae and aquatic plants. However, people use them as pet turtles. Therefore, you will find them in large rivers and lakes when they are not living as human pets. Ouachita map turtles are endemic to Texas, Louisiana, Mississippi, Alabama, Tennessee, Ohio, West Virginia, and Illinois.
False map turtles are aquatic turtles. They are called sawback turtles because of their serrated shell. The colors of their carapace are olive to brown, with yellow marks. However, their bodies can have different shades of color ranging from greyish brown to black, while their eye colors could be brown, yellow, white, or green.
Male turtles are smaller than females. They grow to 5.75 inches, while females grow to 10.75 inches in length. Their diet consists of insects, worms, crayfish, snails, dead fish, and aquatic plants. False map turtles prefer to live in large streams. So, you can find them in various Missouri and Mississippi River systems. They are also in rivers in Southwest Louisiana and East Texas.
False map turtles like to spend time in the sun as basking is very important to map turtles. They are a social group, sharing spaces and protecting each other from predators.
Spring is their mating season. They mate in water; reproduction takes about 80 days after the female turtle lays eggs during summer. The female reproductive organ can lay up to 22 turtle eggs per clutch.
Their very close look-a-likes, the Mississippi map turtle, share similar characteristics without lines on the top of their head.
Wood turtles are 8 inches long. Their shells have a unique design. Each part of their scutes looks like a pyramid. Their shells are brown, while their necks and limbs are color red. They prefer to spend time near water, in the shallow parts. However, you can find them in forests and grasslands.
Like most turtles, they are omnivores. They are endemic to New England, Nova Scotia, northern Indiana, and Minnesota. Wood turtles are active in the daytime in the spring season4, but they hibernate during the winter season. Also, they can move faster than other turtles at up to 0.32 kilometers per hour.
The chicken turtle prefers to live in slow-moving, shallow, or still-water bodies. It is carnivorous, so they eat crayfish, dragonflies, tadpoles, spiders, and carrion. Also, they are semi-aquatic, spending more than half the year on land. They enjoy basking as it helps them regulate their body temperature.
The Chicken turtle species have sexual dimorphism. Female turtles are usually bigger than males, growing up to 10 inches. You can find them in the southeastern parts of the United States. There are three chicken turtle species: western, eastern, and Florida chicken turtles. They don’t have a long lifespan, living up to 25 years.
Global warming results from excess heat-trapping greenhouse gases (GHGs) in the earth's atmosphere. Carbon dioxide is the most abundant GHG and, therefore, is considered the primary driver of rising atmospheric temperatures. GHG emissions are also called carbon emissions.
The daily level of carbon dioxide in the atmosphere exceeded 400 parts per million for the first time in human history in 20136. Despite valiant efforts made so far, the amount of daily carbon dioxide is hovering over 420 ppm.
The changing climate has far-reaching consequences for human society. Unfortunately, the consequences are not fairly distributed. Although developed countries are the major contributors to climate change, the effects are felt more in developing countries.
Climate change impacts our environment, economy, physical well-being, and the fabric of society. The rise in sea level increases flooding incidents in coastal communities. Extreme weather events like hurricanes, forest fires, floods, heat waves, and tropical storms are lasting longer and happening more frequently.
Climate change can also affect air quality by increasing ground-level ozone. Agriculture depends on stable climate conditions; therefore, unprecedented droughts, floods, heatwaves, etc., can result in food insecurity. Furthermore, climate change can influence health-determining factors and gravely endanger human health.
Renewable energy is one of the most talked-about climate solutions. It involves harnessing energy from sources other than fossil fuels, such as wind, solar, biomass, hydro, tidal energy, etc.
Embracing the various types of renewable energy has many benefits for climate adaptation. Although it starts out pricey, it can lower long-term energy costs, which is particularly great for low-income communities.
Also, extreme weather events can destabilize the energy supply grid. Most renewable energy options are off-grid and would keep essential services going.
We cannot adapt to climate change without changing how we use land. Land acquisition so far has been based solely on enriching a few pockets. That results in over-exploitation of natural resources, and many people, especially marginalized communities and indigenous people, get victimized in the process.
As climate change begins to impact the availability of natural resources and the viability of land, conflicts may arise. Strong institutions and robust policies are needed to reduce the risk of conflicts.
We need land for conservation, relocating people, shelters, and other purposes. We must also learn how to share the land more harmoniously with nature and other people.
Food security is the state of having reliable access to a sufficient quantity of affordable, nutritious food. The availability of food for people of any class and state, gender or religion is another element of food security. Similarly, household food security is considered to exist when all the members of a family, at all times, have access to enough food for an active, healthy life.[1] Individuals who are food-secure do not live in hunger or fear of starvation.[2] Food security includes resilience to future disruptions of food supply. Such a disruption could occur due to various risk factors such as droughts and floods, shipping disruptions, fuel shortages, economic instability, and wars.[3] Food insecurity is the opposite of food security: a state where there is only limited or uncertain availability of suitable food.
The Seven-Spotted Ladybug, or Sevenspotted Lady Beetle, originates from Europe and is now a common resident in gardens and parks. Humans have brought ladybugs to various regions to control aphid populations; they feed on aphids while patrolling plant stems and leaves.
These beneficial insects’ red forewings feature three black spots each, with an additional spot straddling the wings' junction, lending to its common and scientific name.
Moreover, Seven-Spotted Ladybugs start as eggs, transform into larvae, morph into pupas, and finally emerge as adult ladybeetles. During winter, they enter a dormant phase, called diapause, and huddle together in large clusters, waiting for spring.
