Leptonycteris Yerbabuenae
The lesser long-nosed bat (''Leptonycteris yerbabuenae'') is a medium-sized bat found in Central and North America. It is sometimes known as Sanborn's long-nosed bat or the Mexican long-nosed bat, though the latter name is better avoided since it is also used for the entire genus '' Leptonycteris'' and for one of the other species in it, the greater long-nosed bat (''L. nivalis''). Originally described as a subspecies of the greater long-nosed bat, it was later considered a subspecies of the southern long-nosed bat, before being confirmed as a distinct species. Enthusiasts for the bats often refer to them simply as leptos because they are the best known members of the genus ''Leptonycteris''. The scientific name is derived from the type locality, near Yerbabuena in Guerrero, Mexico. Description Lesser long-nosed bats are relatively small bats, with a total length as adults of around , and weighing between , depending on the time of year. Males and females are similar in size, ...

Bernardo Villa Ramírez
Bernardo Villa Ramírez (May 4, 1911 – November 21, 2006) was a Mexican mammalogist. He published five books and over 100 articles: primarily on the biology of bats and rodents, but also on marine mammals. Born in Teloloapan, Guerrero, Villa Ramírez studied in Guerrero and then Mexico City, returning to his hometown to build a school and become a rural school teacher. He later attended the National Autonomous University of Mexico (UNAM), receiving a master's degree in 1944, then received a second master's from the University of Kansas in 1947. He returned to UNAM as a researcher, professor, and doctoral student, completing his dissertation on the bats of Mexico in 1966. His resulting book, ''Los murcielagos de Mexico'', became a standard reference for Mexican bat researchers. His memberships and service in scientific societies included an honorary life member of the American Society of Mammalogists The American Society of Mammalogists (ASM) was founded in 1919. Its primary pur ...

Semi-arid
A semi-arid climate, semi-desert climate, or steppe climate is a aridity, dry climate sub-type. It is located on regions that receive precipitation below Evapotranspiration#Potential evapotranspiration, potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to ...

Honduras
Honduras, officially the Republic of Honduras, is a country in Central America.

Its Capital city, capital and largest city is Tegucigalpa. Honduras was home to several important Mesoamerican cultures, most notably the Maya civilization, Maya, before Spanish colonization of the Americas, Spanish colonization in the sixteenth century. The Spanish introduced Catholic Church, Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability, and remains one of the poorest countries in the Western Hemisphere. In 1960, the northern part o ...

C3 Carbon Fixation
carbon fixation is the most common of three metabolic pathways for carbon fixation in photosynthesis, the other two being and CAM. This process converts carbon dioxide and ribulose bisphosphate (RuBP, a 5-carbon sugar) into two molecules of 3-phosphoglycerate through the following reaction: :CO2 + H2O + RuBP → (2) 3-phosphoglycerate This reaction was first discovered by Melvin Calvin, Andrew Benson and James Bassham in 1950. C3 carbon fixation occurs in all plants as the first step of the Calvin–Benson cycle. (In and CAM plants, carbon dioxide is drawn out of malate and into this reaction rather than directly from the air.) Plants that survive solely on fixation ( plants) tend to thrive in areas where sunlight intensity is moderate, temperatures are moderate, carbon dioxide concentrations are around 200 ppm or higher, and groundwater is plentiful. The plants, originating during Mesozoic and Paleozoic eras, predate the plants and still represent approximatel ...

Agave
''Agave'' (; ; ) is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large Rosette (botany), rosettes of strong, fleshy leaves. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette semelparity, flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Along with plants from the closely related genera ''Yucca'', ''Hesperoyucca'', and ''Hesperaloe,'' various ''Agave'' species are popular ornamental plants in hot, dry climates, as they require very little supplemental water to survive. Most ''Agave'' species grow very slowly. Some ''Agave'' species are known by the common name "century plant". is a Spanish word that refers to all of the large-leafed pla ...

Cacti
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of '' Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...
