Figure2. Angle ϕmin for the minimum planetary insolation configuration against the mass of the secondary star m2 for various masses of the primary star m1. We assume a planet on a circular orbit at a distance of 2.37au from the binary barycenter, while the binary stars are evolved on a circular orbit with a semi-major axis of 1au.

Figure 3. Dynamically informed habitable zones for the Kepler-16, Kepler-34, and Kepler-35 systems. Plots in the left column show the different types of habitable zones without the presence of the known giant planets. The right column includes the influence of the known giant planets. Red colored regions correspond to uninhabitable areas, blue, green, yellow, and purple colors denote the PHZ, the EHZ, the AHZ, and unstable areas according to Holman and Wiegert (1999) stability criterion, respectively. Violet colored areas mark regions of dynamical instability caused by the giant planet in the system (Petrovich, 2015 dynamical stability criterion). The vertical black lines denote the classical habitable zone limits, while the horizontal white line in the left column plots marks the current eccentricity of the binary star orbit. In the right column graphs, the white line marks the current eccentricity of the giant planet orbit. Finally, the black dot in the right column plots shows the position of the giant planet in the presented parameter space.

If you're considering planting Thuja Green Giant trees in your yard or garden, it's important to choose the right time of year based on your location. Thuja Green Giants are known for their fast growth rate and hardy nature, making them a popular choice for hedges, privacy screens, and landscaping. But planting at the wrong time can result in stress or damage to the trees, leading to poor growth or even death. In this blog post, we'll provide a table of recommended planting times based on regions and states in the United States, so you can ensure your Thuja Green Giants thrive in your local climate.

Thuja Green Giants, also known as Western Red Cedars, are native to North America and thrive in a wide range of conditions. They can tolerate a variety of soil types, from sandy to clay, and prefer moist, well-draining soil. They are also adaptable to both sun and partial shade. However, they can be sensitive to extreme heat or drought, so it's important to choose the right time to plant them.

Planting times can vary based on your region and state, as well as other factors such as altitude, soil type, and microclimate. The following table provides general guidelines for planting Thuja Green Giants based on your location:

In the Northeast and Midwest, where temperatures can fluctuate greatly between seasons, it's best to plant Thuja Green Giants in the spring or early fall, when the soil is still warm but the weather is cooler. This allows the roots to establish before winter and reduces the risk of stress or damage from extreme heat or cold.

In the Southeast and Southwest, where summers can be hot and dry, it's better to plant in the fall or winter, when temperatures are cooler and there is more moisture in the soil. This reduces the risk of heat stress and allows the roots to establish before the hot season.

It's important to note that these are general guidelines, and your local climate and conditions may require different planting times. Be sure to do research specific to your area and consult with a local gardening expert or nursery before planting.

Hardiness zones are a way to describe the climatic conditions of different regions. They are determined by average minimum temperatures, and are used as a guide to help gardeners choose plants that are well-suited to their area.

In zones 5 and 6, where winters are still cold but shorter, planting in the spring or early fall is recommended, to take advantage of milder temperatures and reduce stress during extreme heat or cold.

It's important to keep in mind that these are general guidelines, and your local conditions may vary. It's always a good idea to consult with a local gardening expert or nursery to get advice specific to your area.

As I watched, a dog trotted off-leash into the planting site and squatted to leave a deposit right in front of us. The owner arrived next, an older woman in an elegant purple jacket holding a utilitarian blue bag. The hues seemed too bright, out of place in the muted, almost black-and-white shades of the morning.

Over two days of work, the crew planted 1,000 individuals from five native species into this site. When they were through, the transition zone was the new home to hopeful clusters of creeping wild rye, western ragweed, marsh baccharis, western goldenrod, and Pacific aster.

A week later, the planting crew was headed for deep Bay muck along two eroding edges of the salt marsh. The sky was cobalt, and still waters glinted with reflected sunlight. An energetic flock of willets foraged along the mudflat.

Across a stretch of Bay on the Richmond Rod and Gun Club pier, Hammond and a crew from a nationwide restoration company called SOLitude Lake Management moved trays of Pacific cordgrass from pickup trucks onto an airboat. A bystander who looked like a hunter asked Hammond what they were up to, and they got talking.

Last night, we ran into a phenomenon that is found primarily in deep-sea invertebrates (animals without backbones). That is the phenomenon of gigantism in the deep sea, when animals grow much larger than their shallow water relatives.

Sometimes in images from deep-sea cameras, you see pictures of giant sea spiders, giant amphipods, giant jellyfish, an occasional giant squid etc., far bigger than the average size that we are used to seeing. Last night it was our turn, and we brought up a giant deep-sea shrimp (image on left), far larger than the size that we are used to seeing (image on right).

However, with a large size comes the drawback of needing more food, and while there are fewer predators below 1,000 meters, there are also fewer prey. So, while your size (and spines, for most of the crustaceans) may prevent predators from going after you so you will not get eaten, you run the risk of starving to death because you cannot find enough food to feed your growing body. That is why the deep sea is not filled with huge shrimp, giant squid are few and far between, and jellyfish the size of cars have only rarely been seen.

Mainland Ecuador, on the other hand, has about 20,000 species. The discrepancy between species number on the Islands and the mainland highlights the fact that the Galapagos Islands are separated from the continent by a hostile saltwater barrier reducing the potential for arrival and, once a plant has arrived, establishment is difficult due to the harsh environment. It is worthy of note that more than 30% of native plant species found in Galapagos are endemic (not found anywhere else on earth).

With the establishment of the Galapagos National Park and the Charles Darwin Foundation in 1959, a systematic review of the status of the tortoise populations began. Only 11 of the 14 originally named populations remained and most of these were endangered if not already on the brink of extinction. The only thing saving several of the populations was the longevity of tortoises, keeping some old adults alive until conservation efforts could save their species.

The taxonomy of giant tortoises has changed over the decades since they were first named. Today the different populations are considered separate species of the genus Chelonoidis. There are currently 15 species. Giant tortoises were native to each of the big islands (Espaola, Fernandina, Floreana, Pinta, Pinzn, San Cristbal, Santa Cruz, Santa Fe and Santiago) as well as the five major volcanoes on Isabela Island (Wolf, Darwin, Alcedo, Sierra Negra and Cerro Azul). Two species have been identified from Santa Cruz. Tortoises are now extinct on Fernandina (due to volcanism), Floreana, Santa Fe and Pinta (due to exploitation). Pinta Island had a single known tortoise, Lonesome George, who lived until June of 2012 at the Tortoise Center on Santa Cruz where he spent the final 40 years of his life. A taxidermy specimen of Lonesome George is now on display at the Tortoise Center.

Galapagos tortoises are herbivorous, feeding primarily on cactus pads, grasses, and native fruit. They drink large quantities of water when available, which they can store in their bladders for long periods of time.

Tortoises breed primarily during the hot season (January to May), though tortoises can be seen mating any month of the year. During the cool season (June to November), female tortoises migrate to nesting zones (generally in more arid areas) to lay their eggs. A female can lay from 1-4 nests over a nesting season (June to December). She digs the hole with her hind feet, then lets the eggs drop down into the nest, and finally covers it again with her hind feet. She never sees what she is doing. The number of eggs ranges from 2-7 for saddle-backed tortoises to sometimes more than 20-25 eggs for domed tortoises. The eggs incubate from 110 to 175 days (incubation periods depend on the month the nest was laid, with eggs laid early in the cool season requiring longer incubation periods than eggs laid at the end of the cool season when the majority of their incubation will occur at the start of the hot season). After hatching, the young hatchlings remain in the nest for a few weeks before emerging out a small hole adjacent to the nest cap. The sex of a tortoise is determined by the temperature of incubation, with females developing at slightly hotter temperatures.
