Data and Code for Curveira-Santos et al. "Imbalanced recovery and depleted baselines of a protected mammal community in post-conflict Angola"

Multi-species detection data and R code used to fit the dynamic community occupancy model described in Curveira-Santos et al. "Imbalanced recovery and depleted baselines of a protected mammal community in post-conflict Angola".

Data collection and model formulation details are reported in the main article and supplementary material.

i. Data: “Data.rdata”

Species detection and covariate data from camera-trap surveys conducted conducted in Bicuar National Park, Angola, between 2017 and 2023. The data file contains the following objects:
"K": Two-dimensional effort array with number of 3-day sampling occasion per camera-site and yearly-season;"Yaug": Three-dimensional detection array with number of 3-day sampling occasions where at least one individual was detected, per species (zero-augmented), camera-site, and yearly-season;"season_list": Primary survey periods identifier (yearly-seasonal);"species_list": Species identifier (scientific names);"covariates": Site-specific (rows) covariate values (columns) for mean above-ground vegetation biomass (bmass), time since last fire (tsfire), distance to nearest human access (dhuma), distance to nearest waterhole (dwater), camera target feature (trail), camera height (height), and vegetation biomass at site (sbmass).ii. Model Code: “DCOM.R”

JAGS code written for program R to implement the dynamic community occupancy model.

本数据集包含用于拟合Curveira-Santos等人发表于《冲突后安哥拉受保护哺乳动物群落的失衡恢复与枯竭基线》一文中的动态群落占有模型（dynamic community occupancy model）的多物种种群检测数据与R代码。
数据采集与模型构建细节已在主论文及补充材料中完整说明。
i. 数据集文件：“Data.rdata”
该数据集来源于2017年至2023年间在安哥拉比夸国家公园（Bicuar National Park）开展的红外相机监测调查（camera-trap surveys）所获取的物种种群检测数据与协变量数据。数据文件包含以下对象：
"K": 二维采样投入数组，记录各相机位点按年度季划分的3天采样周期总次数；
"Yaug": 三维检测数组（经零扩充，zero-augmented），按物种种群、相机位点及年度季维度，统计至少检出1只个体的3天采样周期总数；
"season_list": 主要调查周期（年度季）标识符；
"species_list": 物种种群标识符（采用科学学名）；
"covariates": 位点特异性协变量矩阵（行代表采样位点，列代表协变量），涵盖平均地上植被生物量（bmass）、距末次火灾时长（tsfire）、距最近人类通行点距离（dhuma）、距最近水源点距离（dwater）、相机架设目标特征（trail）、相机架设高度（height）及位点植被生物量（sbmass）。
ii. 模型代码：“DCOM.R”
该代码为基于R语言编写的JAGS代码，用于实现动态群落占有模型。
