摘要。
长期的鸟类环志计划提供了鸟类种群的人口统计学比率的知识，但我们目前缺乏物种丰富的热带生态系统中大多数鸟类种群的人口统计学比率的信息。在热带地区，条带划分通常是在长时间或不规则的采样情况下进行的，这使得难以选择适当的捕获-标记-再捕获（CMR）模型。在这里，我们解决了共同的挑战，收集和分析数据，以估计生存率的居民新热带鸟类使用20年的环志工作在墨西哥作为一个案例研究。我们应用Cormack-Jolly-Seber和Barker模型来估计物种的表观生存和重捕概率，并提供了足够的生存分析数据。我们能够分析136个总物种的6个常驻物种;表观生存概率范围从0.30到0.77，和夺回概率从0.11到0.52。对于以连续、不均匀或不规则间隔收集现有数据的监测程序，我们建议应用Barker模型，因为它在使用可用条带数据方面更有效，并且不经常违反CMR假设。我们建议监测计划持续10年以上，并为初级和次级采样时机以及蚊帐数量、潜在蚊帐配置和空间尺度范围提供额外的协议建议。这些基线建议可能会促进我们对热带生态系统中鸟类存活率的了解，这对于在不断变化的环境条件下管理热带鸟类种群至关重要。
ABSTRACT.
Long-term bird-banding programs provide knowledge of the demographic rates of avian populations, but we currently lack information on demographic rates of most bird populations in species-rich tropical ecosystems. Banding in tropical regions is typically conducted with protracted or irregular sampling occasions that make the choice of the proper capture—mark—recapture (CMR) model difficult. Here, we address common challenges related to collecting and analyzing data to estimate survival rates of resident Neotropical birds using 20 years of banding efforts in Mexico as a case study. We applied Cormack-Jolly-Seber and Barker models to estimate apparent survival and recapture probabilities of species with sufficient data for survival analyses. We were able to analyze 6 resident species of 136 total species; apparent survival probabilities ranged from 0.30 to 0.77, and recapture probabilities from 0.11 to 0.52. For monitoring programs with existing data collected at continuous, uneven, or irregular intervals, we recommend the application of the Barker model over other models because it was more efficient in the use of available banding data and less often violated CMR assumptions. We recommend that monitoring programs last >10 years and provide additional protocol suggestions for primary and secondary sampling occasions, as well as the number of nets, potential net configurations, and the extent of the spatial scale. These baseline recommendations are likely to foster an increase in our knowledge of avian survival rates in tropical ecosystems, which is imperative for managing tropical bird populations under changing environmental conditions.
