ABSTRACT The implementation of spatial protection measures is currently a priority in batoid species' conservation strategies, but their spatial ecology remains largely unknown. We provide some preliminary insights into the movement patterns of the white skate (Rostroraja alba), a batoid classified as Critically Endangered in European waters. Three individuals (two females: one mature, one immature; and one immature male) were monitored with acoustic telemetry in a marine protected area (Portugal). The mature female remained present in the study area throughout the whole monitoring period (20 months). Residency analyses revealed this specimen spent more than 70% of the time within this coastal marine park. The immature female and the immature male were only detected during three and four months, respectively. Whether the uncovered movement patterns are common within the population remains unclear, but the present study provides useful information to better plan future research on the movement ecology of a rather unstudied species.

对与海洋保护区相关的区域极度濒危冰鞋（Rostroraja alba）的空间生态学和运动模式的初步见解

摘要 空间保护措施的实施是目前蝙蝠类物种保护策略的优先事项，但它们的空间生态仍然很大程度上未知。我们对白鳐（Rostroraja alba）的运动模式提供了一些初步见解，这是一种在欧洲水域被列为极度濒危物种的蝙蝠。在海洋保护区（葡萄牙）使用声学遥测技术监测了三只个体（两只雌性：一只成熟，一只未成熟；一只未成熟雄性）。在整个监测期间（20 个月），成年雌性一直存在于研究区域。居住地分析显示，这个标本有超过 70% 的时间在这个沿海海洋公园内度过。未成熟的雌性和未成熟的雄性分别仅在三个月和四个月内被检测到。
