Abstract:

This study surveyed the prevalence of chlamydial infection among farms in the mid-northeastern provincial cluster of Thailand by PCR and phylogenetic analyses of the sequences. Samples from 94 crocodiles were collected from 17 farms in five provinces together with farm management data. Chlamydiaceae was found in 48.94% of the samples (46/94). Of the 17 pooled samples analyzed using 16S rRNA sequencing, four samples exhibited 99.3 to 99.5% nucleotide identity with Chlamydia psittaci, three samples exhibited 99.1 to 99.3% nucleotide identity with C. crocodili, and one sample exhibited similarity

Abstract:

Crocodiles, gharials and alligators (order Crocodilia), are aquatic reptiles that live in the tropics of Asia, America, Africa, and Australia. Asian countries such as India, Indonesia, Malaysia, and tropics of Australia are the stronghold of the family Crocodylidae. Among all 23 crocodile species, nine species occur in Asia and its surroundings, including the only member of Gavialidae and Alligatoridae family. They are “mugger” or “Crocodylus palustris,” “saltwater crocodile” or “Crocodylus porosus,” “Philippine crocodile” or “Crocodylus mindorensis,” “New Guinea crocodile” or “Crocodylus nova

We provide the results on the first systematic effort to study cave-dwelling crocodiles in central Belize. For nearly three decades, managers at Runaway Creek Nature Reserve have frequently observed crocodile tracks and trackways in caves, while subterranean observations of crocodiles were less frequent. We surveyed five caves previously identified as crocodile habitat by wading (up to waist deep) and kayaking; we also deployed trail cameras in five of six flooded caves. Crocodiles were directly observed in two caves and trail camera footage was captured of a crocodile exiting a third cave. Gi

Abstract:

Throughout Africa, feelings towards crocodiles vary according to the danger or fear experienced by communities living alongside them. Crocodile conservation programmes must therefore be based on reliable assessments of cultural attitudes towards these reptiles. In this study, we interviewed a random sample of 300 persons in six states in southern Nigeria to determine their perception of crocodiles. Our results revealed that most respondents were very familiar with crocodiles, with animals being regularly sighted but only in small numbers. Most interviewees were aware of just two crocodile type

We investigated the status of crocodiles in the U Minh Thuong Nature Reserve by conducting field surveys and interviewing local people.

Siamese Crocodiles (<em>Crocodylus siamensis</em>) are critically endangered, with populations in only four countries, including Thailand.

Farming and ranching crocodiles has of late attracted much entrepreneural attention in Africa especially in the SADCC region of Southern Africa where crocodiles still occur in abundance. There are two main reasons for this sudden interest. 1) Crocodile farming and ranching is rewarding in both economic and commercial terms; and 2) the economic value of crocodiles provides a good argument in support of sustainable conservation of the crocodile.

Congenital defects have been described in almost every vertebrate group. In crocodiles, teratology alterations have been described in captive animals (pets, zoos, farms) such as Crocodylus niloticus or Gavialis gangeticus. The present study aimed to characterize congenital malformations of C. acutus from a farm in Lomas de Matunilla, Ballestas, Bolívar, Colombia. A total of 550 unhatched eggs were examined after embryo death. A total of 61 embryos pre

Abstract:

In contrast to other anthropogenic activities, little is known about impact of road construction on reptile’s distribution in urban areas. Therefore, the present study aimed at quantifying impact of road construction on C. suchus distribution. It was conducted from February 2016 to May 2018, in the urban Park Bangr-weoogo. C. suchus populations were counted day by used binoculars pairs and night by spotlight. The different observations were carried on foot. Every time, we observed crocodile, we visually estimate its size class. When we couldn’t appreciate the size of an individual, it was just

Saltwater crocodile (Crocodylus porosus) is the largest and longest crocodilian species in the world. The increasing human activities along river have been caused habitat degradation in watersheds. On the other hand, the crocodile population may have increased after decades of protection. Rivers that are habitat for crocodiles and have increased human occupancy have led to increase conflicts with crocodiles. This increasing cases requires the management authorities to immediately issue policies based on scientific data. Population data and habitat characteristics of saltwater crocodiles in the

Abstract:

Secretory phospholipase A2, an enzyme that exhibits substantial immunological activity, was measured in the serum of three species of diverse West African crocodiles. Incubation of different volumes of crocodile serum with bacteria labeled with a fluorescent fatty acid in thesn-2 position of membrane lipids resulted in a volume-dependent liberation of fluorescent probe. Serum from the Nile crocodile (Crocodylus niloticus) exhibited slightly higher activity than that of the slender-snouted crocodile (Mecistops cataphractus) and the African dwarf crocodile (Osteolaemus tetraspis).

In West Africa, crocodiles may constitute the main predators for manatees apart from humans. Here, we explore 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), testing the hypotheses that (i) manatees may avoid crocodiles in order to minimize risks of predation, and (ii) the two crocodile species do compete.

Saltwater crocodiles (Crocodylus porosus) are potentially dangerous to humans, yet they have major cultural value to many people in Timor-Leste. Recent increases in attack risk are influencing traditional attitudes, threatening culls of remaining wild crocodile populations. To understand patterns that may assist mitigation, we compiled attack records for the period of April 2007 to April 2014, using the CrocBITE online database. Recorded attacks (n=45) showed a high fatality rate (82.2%), the majority (77.8%) being recorded since 2010. The highest proportion of attacks (46.7%) occurred in sout

Epibiosis is a form of symbiosis where one organism resides on the surface of another. To understand this relationship, the present study examines the ecological and evolutionary context of it, as well as the behavioral and physiological mechanisms that facilitate it. Furthermore, the present study evaluates the implications and challenges for conservation of this relationship. To achieve these objectives, a

Populations of Siamese crocodiles (Crocodylus siamensis) have severely declined because of hunting and habitat fragmentation, necessitating a reintroduction plan involving commercial captive-bred populations. However, hybridization between Siamese and saltwater crocodiles (C. porosus) has occurred in captivity. Siamese crocodiles commonly have post-occipital scutes (P.O.) with 4–6 scales, but 2–6 P.O. scales were found in captives on Thai farms. Here, the genetic diversity and population structure of Siamese crocodiles with large P.O. variations and saltwater crocodiles were analyzed using mit

Beginning with the textual and visual traditions linking the crocodile with Africa and the Middle East, I read sixteenth- and seventeenth-century travel narratives categorizing American reptiles as “crocodiles” rather than “alligators,” as attempts to mitigate the disruptive strangeness of the Americas.

The analysis shows that the crocodile folklore of the Philippines is strongly connected to that of the indigenous people in Borneo.
