Analysis of external injuries in captive and free-ranging Morelet's crocodiles Crocodylus moreletii was performed in the northern wetlands of Campeche, Mexico. From March to September of 2007, a total of 52 free-ranging and 51 captive Morelet's crocodiles were studied. Captive crocodiles presented significantly more injuries. Sixteen free-ranging crocodiles presented some type of lesion, mostly superficial abrasions. Nineteen captive crocodiles presented lesions, mostly incisions from agonistic interactions. Overall, the injuries with highest prevalence were the incisions. The tail was the most frequently injured body region. Injuries were more common in adults than in other size classes. Conversely, the presence of lesions caused by the parasite Paratrichosoma spp. was greater in crocodiles captured in the coastal channels (mangrove habitat). The information presented here is important to understand some of the effects of individual interactions and to foresee and manage the consequences of conservation and management activities of crocodile populations.
对墨西哥坎佩切北部湿地圈养和野生的莫雷莱鳄(Crocodylus moreletii)的外伤进行了分析。在2007年3月至9月期间,共研究了52只野生和51只圈养的莫雷莱鳄。圈养的鳄鱼出现的损伤明显更多。16只野生鳄鱼出现了某种类型的损伤,大多为浅表擦伤。19只圈养鳄鱼出现了损伤,大多是因争斗相互作用造成的切口。总体而言,发生率最高的损伤是切口。尾巴是最常受伤的身体部位。损伤在成年鳄鱼中比在其他体型类别中更常见。相反,在沿海河道(红树林栖息地)捕获的鳄鱼中,由寄生虫Paratrichosoma spp.引起的损伤更多。此处提供的信息对于理解个体相互作用的一些影响以及预测和管理鳄鱼种群保护与管理活动的后果很重要。
