Climax species, also called late seral, late-successional, K-selected or equilibrium species, are plant species that will remain essentially unchanged in terms of species composition for as long as a site remains undisturbed.
 They are the most shade-tolerant species of tree to establish in the process of forest succession.
 The seedlings of climax species can grow in the shade of the parent trees, ensuring their dominance indefinitely.
 A disturbance, such as fire, may kill the climax species, allowing pioneer or earlier successional species to re-establish for a time.
 They are the opposite of pioneer species, also known as ruderal, fugitive, opportunistic or R-selected species, in the sense that climax species are good competitors but poor colonizers, whereas pioneer species are good colonizers but poor competitors.
 Climax species dominate the climax community, when the pace of succession slows down, the result of ecological homeostasis, which features maximum permitted biodiversity, given the prevailing ecological conditions.
 Their reproductive strategies and other adaptive characteristics can be considered more sophisticated than those of opportunistic species.
 Through negative feedback, they adapt themselves to specific environmental conditions.
 Climax species are mostly found in forests.
 Climax species, closely controlled by carrying capacity, follow K strategies, wherein species produce fewer numbers of potential offspring, but invest more heavily in securing the reproductive success of each one to the micro-environmental conditions of its specific ecological niche.
 Climax species might be iteroparous, energy consumption efficient and nutrient cycling.
Gray langurs or Hanuman langurs, the most widespread langurs of the Indian Subcontinent, are a group of Old World monkeys constituting the entirety of the genus Semnopithecus (from Ancient Greek σεμνός "semnós", “revered, august, holy”, and πίθηκος "píthēkos", “ape, monkey”).
 All taxa have traditionally been placed in the single species "Semnopithecus entellus".
 In 2001, it was recommended that several distinctive former subspecies should be given species status, so that seven species are recognized.
 A taxonomic classification with fewer species has also been proposed.
 Genetic evidence suggests that the Nilgiri langur and purple-faced langur, which usually are placed in the genus "Trachypithecus", actually belong in "Semnopithecus".
Peninsula Lake is a lake in Alberta, Canada.
 The lake is located 160 km southeast of the city of Edmonton.
 The salinity of Peninsula Lake causes characteristics such as temperature, nutrient concentrations and plant and animal communities to contrast with those from freshwater lakes.
 The lake is contains high levels of sulphate, sodium and bicarbonate/carbonate concentrations which, are produced by saline groundwater in the region.
 In winter, the temperature of water under the ice drops to 0°C, extremely low, even for Alberta lakes.
 Although the lake contains high mineral levels, plant growth is sparse.
 A few planktonic invertebrates are exceptionally abundant, but there are fewer species than in freshwater lakes.
 There are no fish living in the lake.
Cambaridae is the largest of the three families of freshwater crayfish, with over 400 species.
 Most of the species in the family are native to North America east of the Great Divide (south to Guatemala and including the island Cuba), such as the invasive species "Procambarus clarkii" and "Orconectes rusticus".
 Fewer species, all in the genus "Cambaroides", live in eastern Asia.
Rossioglossum grande (tiger orchid) is an epiphytic species of orchid native to the area from Chiapas to Costa Rica.
 The plant may grow four to eight flowers, each may reach up to 13 inches in diameter.
 The flowers are a glossy bright golden yellow with brown barring.
 Larger pedals are yellow with the lower half red-brown.
 The lip is white and sometimes flecked with red-brown.
 The pseudobulbs carry a gray-green color to them, and grow from 4 to 10 cm, each with two leaves.
 It prefers hot, wet summers and cool, dry winters.
 It mainly flowers in the winter.
Bruckenthalia is a genus of plants consisting of only one species, Bruckenthalia spiculifolia (spike heath) an evergreen shrub native to southeastern Europe and Asia Minor.
 It is a dwarf and heath-like plant to 10 in high.
 Suitable for rock gardens and borders.
 Leaves are dark green.
 The flowers in terminal clusters of rose-pink, bell-shaped appear in early summer.
The native flora of Chile is characterized by a higher degree of endemism and relatively fewer species compared to the flora of other countries of South America.
 A classification of this flora necessitates its division into at least three general zones: the desert provinces
Rossioglossum is a genus of flowering plants from the orchid family, Orchidaceae.
 It has 9 currently recognized species (as of May 2014), all native to Mexico, Central America, and northern and western South America.
The Sylvioidea are a clade of passerine birds, one of at least three major clades within the Passerida along with the Muscicapoidea and Passeroidea.
 It contains about 1300 species including the Old World warblers, Old World babblers, swallows, larks, bulbuls, and perhaps the tits.
 Members of the clade are found worldwide, but fewer species are present in the Americas.
This is a list of the native wild mammal species recorded in Central America.
 Central America is usually defined as the southernmost extension of North America; however, from a biological standpoint it is useful to view it as a separate region of the Americas.
 Central America is distinct from the remainder of North America in being a tropical region, part of the Neotropic ecozone, whose flora and fauna display a strong South American influence.
 The rest of North America is mostly subtropical or temperate, belongs to the Nearctic ecozone, and has many fewer species of South American origin.
