Global diversity of crocodiles (Crocodilia, Reptilia) in freshwater

  title={Global diversity of crocodiles (Crocodilia, Reptilia) in freshwater},
  author={Samuel Martin},
Living crocodilians include the 24 species of alligators, caimans, crocodiles and gharials. These large semi-aquatic ambush predators are ubiquitous in freshwater ecosystems throughout the world’s tropics and warm temperate regions. Extant crocodilian diversity is low, but the group has a rich fossil record in every continental deposit. Most populations suffered from over-hunting and habitat loss during the twentieth century and even though some species remain critically endangered others are… Expand

The ecological importance of crocodylians: towards evidence‐based justification for their conservation
This work argues that the ecological roles and importance of large predators within freshwater ecosystems are poorly understood, constraining the design and implementation of optimal conservation strategies for freshwater ecosystems. Expand
A review of the taxonomy of the living Crocodiles including the description of three new tribes, a new genus, and two new species.
The taxonomy of the living Crocodilians is reviewed and the nomenclature of most living species is updated. Expand
Lower Miocene alligatoroids (Crocodylia) from the Castillo Formation, northwest of Venezuela
Crocodyliform diversity was particularly high during the middle and late Miocene of South America, with up to 12 species recovered from a single geological unit. Nonetheless, the early Miocene fossilExpand
Early Miocene gastropod and ectothermic vertebrate remains from the Lesvos Petrified Forest (Greece)
The present findings represent one of the best-documented Early Miocene gastropod and fish faunas in the Aegean/southern Balkans, thus adding to the knowledge of early Miocene amphibians and reptiles from that region and providing valuable information on the local subtropical ecosystem. Expand
Macro-habitat preferences by the African manatee and crocodiles – ecological and conservation implications
The macro-habitat selection of manatees and two species of crocodiles (West African crocodiles Crocodylus suchus and dwarf crocodile Osteolaemus tetraspis) in the Niger Delta (Nigeria) is explored, testing the hypotheses that (i) manatee may avoid crocodiles in order to minimize risks of predation, and (ii) the two crocodile species do compete.

Morphometrics, ecotoxicology and stable isotope ecology of Nile crocodiles (Crocodylus niloticus) in KwaZulu-Natal, South Africa.
Knowledge of individual body size and sex are necessary data for analyses of animal population demographics and size structure, but little information exists regarding free-ranging Nile crocodileExpand
Paleobiogeographic distribution of Testudinata and neosuchian Crocodyliformes in the Morrison Formation (Upper Jurassic) of North America: Evidence of habitat zonation?
Abstract Nearly 150 occurrences of turtles and neosuchian crocodyliforms in the Upper Jurassic Morrison Formation indicate that, by number of localities and number of specimens, both areExpand
Marine Reptiles
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, which aims to provide real-time information about the phytochemical properties of planktonic strata of the Great Barrier Reef. Expand
Riparian vegetation structure and the hunting behavior of adult estuarine crocodiles
It is found individual crocodiles were actively selecting overhanging vegetation and that the protrusion of trees from the tree line was key to site selection by crocodiles, as well as influencing both the presence and group size of sleeping macaques. Expand
Freshwater Reptile Persistence and Conservation in Cities: Insights from Species Occurrence Records
Reptiles are rarely included in urban freshwater biodiversity monitoring and conservation. We explored the global persistence of freshwater dependent turtles, lizards, crocodilians and snakes inExpand


Rediscovery of relict populations of the Nile crocodile Crocodylus niloticus in south-eastern Mauritania, with observations on their natural history
Abstract In 1998 and 1999, relict populations of the Nile crocodile Crocodylus niloticus were rediscovered in south-eastern Mauritania, 70 years after the last reports of their existence and 6 yearsExpand
Diets of Amazonian Crocodilians
There is an inverse relationship between the number of terrestrial invertebrates eaten and thenumber of fish eaten by different size classes of Caiman crocodilus, suggesting that mutually exclusive foraging modes are used for those prey categories. Expand
Crocodilians in Perspective
The prediction of the 1960s that crocodilians would soon be extinct has happily proven to be unduly pessimistic. The survival and recovery of substantial stocks provides us with the unexpectedExpand
Adaptations of Crocodylus acutus and Alligator for life in saline water
The major adaptations to saline water of hatchling C. acutus are a low intake of sodium, an ability to selectively drink water of lower salinities, and to grow very rapidly to a size much more tolerant of immersion in 35 ppt sea water. Expand
Historical zoogeography of the eusuchian crocodilians: a physiological perspective
It is proposed that Gavialis and Tomistoma, now restricted to fresh waters, may have been derived secondarily from ancestors adapted to salt water, and that anatomical and physiological adaptations to a marine existence have played an important role in eusuchian history. Expand
▪ Abstract A review of crocodylian phylogeny reveals a more complex history than might have been anticipated from a direct reading of the fossil record without consideration of phylogeneticExpand
Crocodiles : status survey and conservation action plan
Aimed at government agencies, management authorities, funding agencies, researchers, non-governemental organisations and other conservation bodies, it provides an updated set of action recommendations for each of the 23 species of crocodilians. Expand
Salinity Relations of Crocodiles in Florida Bay
Field data from Florida Bay tend to confirm that C. acutus hatchlings are intolerant of 35%o (100%) sea water. Expand
Crocodilian diversity in space and time; the role of climate in paleoecology and its implication for understanding K/T extinctions
The survival of such a demonstrably climate-sensitive group strongly suggests that a climatic explanation for the K/T mass extinctions, especially the demise of the dinosaurs, must be reconsidered. Expand
Amphibious behavior of Alligator mississippiensis: roles of a circadian rhythm and light.
Movement between land and water was characterized by a decrease in body temperature, which suggests that it was not simply a proximate heat-seeking response, and a changing response to light is viewed as an adaptation to seasonal changes in heat availability. Expand
