Tule Shrew
The tule shrewEdward William Nelson & Edward Alphonso Goldman (1909): ''Eleven new mammals from Lower California.'' In: Proceedings of the Biological Society of Washington No. 22:p 23–28. (''Sorex ornatus juncensis'') is a possibly extinct subspecies of the ornate shrew (''Sorex ornatus''). It was confined to the Baja California peninsula in Mexico. Description The holotype, a young adult female, has a total length of 101 mm, a tail length of 41 mm and a hindfood length of 12.5 mm. The condylobasal length of the skull is 16.2 mm, the basal length is 13.9 mm, the breadth of the braincase is 7.5 mm, the palatal length is 7.2 mm, and the interorbital breadth is 3.5 mm. In comparism to the ornate shrew the braincase is higher, narrower and less flattened. The tail is slightly longer and the feet are more dusky. The upperparts and sides are grey or slightly darker. The upperparts are smokey grey with a mixed hazel and vinaceous-buff wash. The ta ...

Proceedings Of The Biological Society Of Washington
In academia and librarianship, conference proceedings is a collection of academic papers published in the context of an academic conference or workshop. Conference proceedings typically contain the contributions made by researchers at the conference. They are the written record of the work that is presented to fellow researchers. In many fields, they are published as supplements to academic journals; in some, they are considered the main dissemination route; in others they may be considered grey literature. They are usually distributed in printed or electronic volumes, either before the conference opens or after it has closed. A less common, broader meaning of proceedings are the acts and happenings of an academic field, a learned society. For example, the title of the ''Acta Crystallographica'' journals is New Latin for "Proceedings in Crystallography"; the ''Proceedings of the National Academy of Sciences of the United States of America'' is the main journal of that academy.

Ornate Shrew
The ornate shrew (''Sorex ornatus'') is a species of mammal in the family Soricidae (shrews). It is endemic to western North America, ranging from Northern California in the United States to Baja California in Mexico. Eight subspecies are known, including the extinct tule shrew (''S. o. juncensis''), known only from four specimens collected in 1905, and the Suisun ornate shrew (''S. o. sinuosus''), a species of conservation concern in California. Through skull morphology research and genetic testing on Ornate shrew populations, it has been shown that there are three main genetic subdivisions: The Southern, Central and Northern. These three genetic subdivisions of Ornate shrew arose from populations of Ornate shrews getting geographically isolated from other populations. Description Ornate shrews are small; they weigh on average . The total length of the animal averages with a hind foot measuring . The tail is relatively short, measuring . The shrew molts, with a change ...

Baja California
Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California (). It has an area of (3.57% of the land mass of Mexico) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur. The state has an estimated population of 3,769,020 as of 2020, significantly higher than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California, to its north. Over 75% of ...
