Our Living Breathing Home, Earth ( a quick 20 year peek)

In 1997 NASA began a continuous “view” of Earth, the entire earth.

The amazing animation from NASA (below) shows, in a few minutes, the last twenty years of Earth’s plant life.  The ebb and flow of the seasons, the breathing in and breathing out, and the changes from year to year.

The living earth (NASA 1997-2017)
Our living Earth (NASA 1997-2017)

White represents snow cover (a good indicator for following the winter season  ) , brown to dark green on land represents low to large presence of vegetation (that light green on land is generally the growth spurt of new plants and the dying back of seasonal plants), and in the ocean purple to dark blue indicate low levels of phytoplankton with the brighter shades from green to yellow indicating high levels of phytoplankton.

In 1997 NASA launched SeaWIFS (the Sea viewing Wide Field-of-view Sensor), which has allowed scientists to record and study, more comprehensively, life on Earth to gather information across all of Earth.

Obviously! …the kind of information/data generated from this type of scientific technology can make a big difference in helping us to monitor and understand life on Earth (and potential life on other planets), climactic events, and longer term impacts.

Coyote In Snow – Preparing for Winter…

This morning we woke up to an early snow and an early visitor…

Coyotes eat most everything they can find… from deer and rabbits to berries and tasty late season treats… apples…

Coyote’s are really adaptable canids (members of the dog family = Canidae); they are omnivores (= eat both plants and animals, like berries and rodents) that over time have adapted from living primarily in prairies and brushy areas to also living in cities, forests, and even along ocean shores.

Coyotes were originally found in central western North America (in yellow). As habitat was altered by human use and wolf populations (and other predators) were reduced, coyote populations expanded and now include almost all of North America and Central America.

Coyotes were first called “jackal”, “Spanish fox”, “prairie wolf”, and “brush”or “little wolf”.  The name “coyote” comes from the Nahuatl name coyōtl; the 1st published use of “coyote” was in Clavijero’s “Historia de Mexico” (1780).

Genetic analysis shows that the relatedness of coyotes, or other canids, is not as simple as once thought.

 

 

 

Coyote facts:

  • Scientific name: Canis latrans .(translates to barking dog)
  • Collective Noun: Pack!
  • Identification:
      • Physical: 3′-4.5′ long (nose to tip tail), 20-45 lbs, similar coloring to a German Shepherd dog. Longer and narrower muzzle than most dogs. Wolves can look a LOT like coyotes from a distance, especially when young, but adult wolves have a much broader muzzle and larger nose pad.
      • Voice: barks, howls, yips, woofs, and growls (will insert audio soon!).
      •                      
      • Scat: varies a LOT! Usually 3″-4″ long and ~1″ diameter. Scat from meat tends to be very dark and smooth, from plant matter variable and crumbly.
  • Range: Almost all of North and Central America historical range western and central North America
  • Habitat: fairly ubiquitous (= almost everywhere on land is possible)
  • Food: Omnivore (eats plant and animals), commonly hunting at night.
  • Natural Lifespan (wild): usually about 4-5 years, but up to 14 years.
  • Breeding/Behavior: Sometimes mate for life, sometimes by year. Breeding takes place from early February through late March and pups are born from April through May. Pups stay in the den the first few weeks. Feeding growing pups can be very demanding, making this time of the year harder on coyote/human interactions;
    • coyotes are very protective of den sites and pups.
    • where coyotes are removed (hunted or trapped) the female coyotes will produce more pups per litter.
  • Taxonomy (see image above): additional info.

Tapanuli Orangutan, Pongo tapanuliensis, the Rarest Great Ape

A study published today (Nov. 2, 2017) in the journal Current Biology (“Morphometric, Behavioral, and Genomic Evidence for a New Orangutan Species“), lists the Tapanuli Orangutan  (Pongo tapanuliensis) as the rarest great ape on Earth, with population estimates lower than 800 individuals (for more info on the the rarest ape/primate species see Rarest Primates). The great apes are all found in the family Hominidae, and include: orangutans, gorillas, chimpanzees, and humans.

Found in the upland forest regions of the island of Sumatra, the Tapanuli orangutan was previously thought to be within the same species as the Sumatran orangutan. Scientists used genetic analysis to confirm the morphometric information ( = analysis of form [shape and size]) to distinguish the Tapanuli from the Sumatran orangutan. Morphologically identifying features included a generally smaller skull, teeth shape, and facial shapes. Interestingly the males long roar call (audio) has a longer duration and higher maximum frequency than the Sumatran or the Bornean orangutan. A bit more obvious to the casual observer, the Tapanuli orangutan has a body build more similar to the Sumatran (linear), but coloring more similar to the Bornean (but even more cinnamon-y). The Tapanuli is also frizzier than both other species, and the female is bearded.

 

Current (as of today) classification for the great apes, Hominidae (only currently extant [ = living] species included), and all but 3 are considered critically endangered and 2 of the remaining 3 are considered endangered:

  • Family Hominidae
  • Subfamily Ponginae
    • Tribe Pongini
      • Genus Pongo
        • Bornean orangutanPongo pygmaeus
        • Sumatran orangutanPongo abelii
        • Tapanuli orangutanPongo tapanuliensis
  • Subfamily Homininae
    • Tribe Gorillini
      • Genus Gorilla
        • Western gorillaGorilla gorilla
        • Eastern gorillaGorilla beringei
    • Tribe Hominini
      • Subtribe Panina
        • Genus Pan
          • Chimpanzee (common chimpanzee), Pan troglodytes
          • Bonobo (pygmy chimpanzee), Pan paniscus
      • Subtribe Hominina
        • Genus Homo
          • Human, Homo sapiens (modern human is designated Homo sapiens sapiens)
