Question: What do Serbian Hound and St. John's water dog have in common?

 Little is known of the types that went into its genetic makeup, although it was probably a random-bred mix of old English, Irish and Portuguese working dogs.  The number of St. John's water dogs started declining by the start of the 20th century. The St. John's water dog, also known as the St. John’s dog or the lesser Newfoundland, was a landrace (a dog bred for a purpose, not pedigree or appearance) of domestic dog from Newfoundland.  By the early 1980s, the variety was extinct. <SEP>  It is red or tan with a black saddle, neck and cranium and red or tan face.  Its head is flat and sloping, its muzzle pointed, with drop ears of the usual scent hound type.  The Serbian Hound stands 17 to 21 inches (44–56 cm) in height and weighs about 44 pounds (20 kg). The Serbian Hound (Serbian: Српски гонич / "Srpski gonič" ), previously known as the Balkan Hound (Балкански гонич / "Balkanski gonič"), is a pack hunting dog breed used in Serbia.  It is smooth-coated and coarse-haired.  Described as pleasant natured and obedient, the breed is thought to descend from dogs left in the Balkan region by the Phoenicians in ancient times. <SEP> A Dry Forest are defined as a community of trees of different species that coexist in the same environment.  These trees can grow nearby forming a canopy above.  Dry forests lack an abundance of moisture, yet, there is an adequate amount of moisture to sustain the growth of the forest.  Although dry forest tends to grow at an intermediate height compared to moist forest.  Dry forest receives 850-1100mm of precipitation per year.  High quantities of sea salt from the ocean decreases the height of the trees.  Dry forest also consisted of layers of canopies, specifically two canopy layers that commonly found at an elevation below 300 meters.  There is limited dead dry wood for termites to consume, this correlates with low density of termites in dry forests.  The characteristics and development of Virgin Islands Dry Forest are contributed by a unique wind pattern that is usually strong.  Dry Forest usually thrive in environments that have plenty sunshine, steep slopes, on soil that are challenged by thin rocky layers that poorly absorbs water.  Within the three islands in the United States Virgin Islands, St. John has maintained a higher percentage of dry forest cover competing with St. Thomas at 43.1%; St. Croix has limited dry forest cover (9.22%).  St. John and St. Thomas topography has significant steep hills and slopes compared to St. Croix.  St. John is the most protected of the three islands, and as such it has the largest extensive tropical dry forests in the U.S. Virgin Islands.  The island contains 650 native plants, 5,000 or more terrestrial insects, over 180 species of birds, of which 90% are native, and six native mammal bat species.  One of the most common trees in the “native dry forest garden” is the amarat.  They are acacias, (casha bush) but do not have thorns likes most other varieties. <SEP> The Serbian Tricolour Hound ("srpski trobojni gonič" or "trobojac") is a breed of dog of the hound type.  Formerly called the Yugoslavian Tricolour Hound, the name was changed for clarity after the breakup of SFR Yugoslavia in 1991.  The breed was first exhibited at shows in 1950.  At one time it was considered a variation of the Serbian Hound, but was recognised by the Fédération Cynologique Internationale as a separate breed in 1961.
