最近的证据表明，位于墨西哥湾西南部的韦拉克鲁斯珊瑚礁系统内的棕榈龙虾，在1970年代因贾马帕河洪水和马季奇冷水事件而死亡后，可能正在恢复。自这一下降以来，很少有调查记录掌纹夜蛾的状况。该系统中的28个命名生物礁被河流划分为13个北部组和15个南部组。2007至2013年间，我们对24个珊瑚礁进行了调查，以评估海底群落。在北部组调查的11个珊瑚礁中，有7个珊瑚礁和南部组的所有珊瑚礁都有棕榈藻。蜂群通常出现在珊瑚礁的迎风一侧，沿着珊瑚礁边缘或顶部的浅水中。2011年至2013年，我们还记录了北部的两个珊瑚礁(阿涅加达德阿登特罗和维德)和南部的两个珊瑚礁(Periferico和Sargazo)沿带横断面的群落直径和状况。此外，还在里佐(南部)调查了8个永久横断面。共评估了1804个菌落，密度范围为0.02~0.28个/m2(平均(±SD)，菌落直径58±73 cm，每个菌落的活组织比例为89±18%)。母鱼捕食的总患病率为5%，蜗牛的捕食总患病率为2%，火虫的捕食总患病率为1%，患病率为3%。大小频率分布表明，所有地点都具有中到高的产卵潜力，每个地点有15-68%的群体是成熟的，面积超过1 600 cm2。这些健康的和潜在的生殖群体的存在对物种恢复非常重要，特别是因为大加勒比地区的大部分地区仍然几乎没有恢复的迹象。这些珊瑚礁的养护和管理工作至关重要。比奥牧师。特罗普。62(补充)3)：75-84。EPub 2014年9月1日。
Recent evidence shows that Acropora palmata within the Veracruz Reef System, located in the south- western Gulf of Mexico, may be recovering after the die off from the flooding of the Jamapa River and a dra- matic cold water event in the 1970s. Since this decline, few surveys have documented the status of A. palmata. The 28 named reefs in the system are divided into 13 northern and 15 southern groups by the River. Between 2007 and 2013, we surveyed 24 reefs to assess the benthic communities. Seven of the 11 reefs surveyed in the northern group and all in the southern group had A. palmata. Colonies were typically found on the windward side of the reefs in shallow waters along the reef edges or crest. We also recorded colony diameter and condition along belt transects at two reefs in the north (Anegada de Adentro and Verde) and two in the south (Periferico and Sargazo), between 2011 and 2013. In addition, eight permanent transects were surveyed at Rizo (south). A total of 1 804 colonies were assessed; densities ranged from 0.02 to 0.28 colonies/m² (mean (±SD), colony diameter of 58 ± 73cm, and 89 ± 18% live tissue per colony). Total prevalence of predation by damselfish was 5%, by snails 2%, and <1% by fireworms, disease prevalence was <3%. Size frequency distributions indicated that all of the sites had a moderate to high spawning potential, 15-68% of the colonies at each site were mature, measuring over 1 600cm². The presence of these healthy and potentially reproductive colonies is important for species recovery, particularly because much of the greater Caribbean still shows little to no signs of recovery. Conservation and management efforts of these reefs are vital. Rev. Biol. Trop. 62 (Suppl. 3): 75-84. Epub 2014 September 01.
