do you guys even fuckign know about th e pygmy spotted skunk Spilogale pygmaea the smallest fucking carnivore native to mexico as well as one fo the smallest carnivores worldwide ENDEMIC TO COASTAL SOUTHERN MEXICO

Pygmy spotted skunk - Wikipedia

you arent ready for how small it is

finally found the endangered endemic species of the protected nature monument hadce (= serpentinites) u želivky - the minuartia smejkalii !! respectively, my mom noticed this small plant with tiny white flowers growing on the stone. i took two low quality photos of it, the light was poor and i took it primarily so i can post it on inaturalist. im no botanist, but this made me very happy.

Sometimes you'll see a species listed as "endemic" to a certain area. That means that it lives in that place and nowhere else! Some species are "microendemic", meaning they live in only one tiny area. This species, Polianthes zapopanensis, isn't quite a microendemic, but it's pretty close - it only lives in a small area of Jalisco, Mexico, near Guadalajara (and its namesake, Zapopan). It was just described in 2011! Even in well-populated areas, there are more interesting plants to find.

One thing that blows my mind about endemism descriptions right now refers to specific sub quadrant groups of potentially interacting populations. 

Gamodeme, or deme, refers to a local breeding population or mating group within a species, where random mating (panmictism) occurs and is now used mostly for this specific type of phenomena. 

Where as other literature keeps separate usage for the term “population.”

“Being a local interbreeding group of individuals sharing a common gene pool”- Dabzansky, 1935 in Rieger. Which was also supported again by population ecologists in 1976 by literature under ‘Green and Michaelis. 

^this concept of “population” is now how the vast majority of population ecologists seem to quantify the word outside of statistics where it is a large assemblage of specific individuals from the taxon of interest becoming the sample group. Which is a much looser term that could be quantified of large and small amounts of space simultaneously.

Lake Mainit is honored with plentiful assets in both upland and lake ecosystems and is one of the Key Biodiversity Areas (KBA) in the Philippines. A field survey of amphibians and reptiles was conducted in the four municipalities comprising Agusan del Norte portion of Lake Mainit Watershed to determine the species richness, endemicity and conservation status. The methods used were a combination of field observation, reconnaissance survey, pitfall trap method and opportunistic collection. The study found out that 17 species belonging to 13 families, with a total of 69 individuals in the four sampling areas. Polypedates leucomystax recorded the most common species and highest number of individuals followed by Platymantis corrugatus. Highest species diversity index was recorded from Santiago with H’= 1.5. Philippine endemic species were H. pustulatus, P. corrugatus, N. samarensi, M. stejnegeri, H. granducola, P. mindanensis, and S. fasciatus while the two recorded vulnerable species were H. pustulatus and M. Stejnegeri, along these lines, the event of these two species qualifies the area to be protected. In this manner, the low species richness in Lake Mainit watershed could probably go to be archived if the place is completely assessed. Conservation action is still essential to protect and conserve biodiversity in the entire areas.
