“…Raxworthy et al 2008), there have been no projections of how climate change will affect the island's freshwater biodiversity. This is despite a growing number of potential threats (Woodward et al 2010) and the ecosystem's high level of vulnerability (Bamford et al 2017;Máiz-Tomé et al 2018). Finally, we did not observe any direct persecution of Madagascar Jacanas during our surveys, although previous reports suggest this is an additional threat to their persistence (BirdLife International 2018).…”

In the biodiversity hotspot of Madagascar (Myers et al. 2000), freshwater wetlands are considered a highly threatened habitat owing to land-use changes, specifically conversion to rice paddies (Benstead et al. 2003; Kull 2012; Bamford et al. 2017). It is predicted that the severe degradation of Madagascar's wetlands will have a catastrophic impact on biodiversity within these ecosystems, and currently there are few areas offering protection for wetland biodiversity (Bamford et al. 2017). As highlighted by the most-thorough assessment of the freshwater biodiversity of Madagascar to date, 43% of the species inhabiting this ecosystem are currently considered threatened (Máiz-Tomé et al. 2018). The Madagascar Jacana Actophilornis albinucha is one of 22 wetland bird species endemic to Madagascar Introduction

“…Three other East African countries, Madagascar, Kenya, and Uganda, contained the third to fifth largest numbers, respectively. Madagascar has nearly half of all their species threatened [20], and the second largest number of endemics in the CARES priority list. Mexico has the second most CARES species, which is no surprise given that it is one of the top five countries with the most threatened species and the one with the most endemics [19].…”

Freshwater fish represent half of all fish species and are the most threatened vertebrate group. Given their considerable passion and knowledge, aquarium hobbyists can play a vital role in their conservation. CARES is made up of many organizations, whose purpose is to encourage aquarium hobbyists to devote tank space to the most endangered and overlooked freshwater fish to ensure their survival. We found the CARES priority list contains nearly six hundred species from twenty families and two dozen extinct-in-the-wild species. The major families were typically those with the largest hobbyist affiliations such as killifish, livebearers, and cichlids, the latter containing half of CARES species. CARES included every IUCN threatened species of Pseudomugilidae and Valenciidae, but only one percent of threatened Characidae, Cobitidae, and Gobiidae species. No Loricariidae in CARES were in the IUCN red list as they have not been scientifically described. Tanzania and Mexico contained the largest amount of species, with the latter containing the most endemics. Many species were classified differently than the IUCN, including a third of extinct-in-the-wild species classified as least concern by the IUCN. This vast disconnect exemplifies the importance of future collaboration and information exchange required between hobbyists, the scientific community, and conservation organizations.
