An invasive or alien species is an introduced species that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web – for example the purple sea urchin which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter. Since the 20th century, invasive species have become a serious economic, social, and environmental threat.
Bavayia is a genus of lizards in the family Diplodactylidae. Species in the genus Bavayia are also known commonly as New Caledonian geckos or bavayias. The genus is native to the remote New Caledonia and Loyalty Islands. The 41 species are moderately small to medium-sized geckos, and are distinguished from other genera by their tail length and the shape of their digits.

Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to 200 m (660 ft) deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between 510 and 1,268 m.
Scaphiophryne gottlebei, commonly known as the Malagasy rainbow frog, ornate hopper, rainbow burrowing frog, red rain frog or Gottlebe's narrow-mouthed frog, is one of the most highly decorated frogs from Madagascar. The primary threats to this endangered species are habitat loss and capture for the pet trade.
Ecological extinction is "the reduction of a species to such low abundance that, although it is still present in the community, it no longer interacts significantly with other species".
The forest fody is a species of bird in the family Ploceidae. It is endemic to Madagascar.
The Massif de la Hotte is a mountain range in southwestern Haiti, on the Tiburon Peninsula. About 2.5 million years ago, Massif de la Hotte was separated from the Massif de la Selle by a deep, wide sea channel, and formed a separate island. This resulted in a hotbed of endemism in la Hottes bird, plant, and reptile communities. The Massif de la Hotte is subdivided into the Oriental la Hotte in the East, the central la Hotte and the Occidental la Hotte on the Western tip of the Tiburon peninsula. The Occidental la Hotte is relatively remote and is one of the most biologically diverse and significant areas of all of Hispaniola. It also supports some of the last stands of Haiti's dense cloud forest on its peaks.
The golden monkey is a species of Old World monkey found in the Virunga volcanic mountains of Central Africa, including four national parks: Mgahinga, in south-west Uganda; Volcanoes, in north-west Rwanda; and Virunga and Kahuzi-Biéga, in the eastern Democratic Republic of Congo. It is restricted to highland forest, especially near bamboo.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Palleon lolontany is a species of chameleon endemic to Madagascar. It was first described by Raxworthy and Nussbaum in 1995 as Brookesia lolontany. It was since placed in the genus Palleon when that genus was erected in 2013. The International Union for Conservation of Nature (IUCN) rated the species as Near Threatened.
Anthony Hume Whitaker was a New Zealand herpetologist, contributing a 50-year career of fieldwork, pioneering research and species discoveries. His is still the largest collection of reptile and amphibian specimens donated to Museum of New Zealand Te Papa Tongarewa.
Bavayia sauvagii, also known commonly as Sauvage's bavayia and Sauvage's New Caledonian gecko, is a species of lizard in the family Diplodactylidae. The species is endemic to New Caledonia.
Dierogekko is a genus of geckos in the family Diplodactylidae. The genus is endemic to the northwest portion of New Caledonia. They are sometimes known commonly as the striped geckos or the New Caledonian geckos. Dierogekko are small geckos with simple, granular scales and subdued patterning of broad longitudinal stripes or spots. They are similar in overall appearance and habit to closely related geckos in the genera Bavayia and Oedodera, and the type species D. validiclavis was once referred to Bavayia.
Paniegekko is a monotypic genus of geckos in the family Diplodactylidae, containing the species Paniegekko madjo. It is endemic to humid montane forests on Mont Ignambi and Mont Panié in the Panié massif of New Caledonia. It was once considered a species of Bavayia, a similar genus of arboreal geckos. Paniegekko madjo is endangered, owing to predation by introduced rodents and cats combined with habitat degradation by wildfires and introduced pigs and deer. It has not been observed since 1998.
Mining maquis is a type of shrubland biome. It forms on ultramafic rock as a result of forest cover retreat due to repeated wildfires. It is common on New Caledonia.
Bavayia ashleyi is a species of geckos endemic to New Caledonia.
Bavayia astrongatti is a species of geckos endemic to New Caledonia.
Bavayia caillou is a species of geckos endemic to New Caledonia.
