众所周知，温度对尸体的腐烂有很大的影响。然而，相对较少的埋藏学研究调查的季节性分解的影响。在这里，我们建议使用的Koppen-Geiger气候分类系统，并描述了分解的猪（猪）尸体在夏季和冬季附近的林肯，内布拉斯加州，美国。分解进行了评分，并gravesoil化学（总碳，总氮，茚三酮活性氮，铵，硝酸盐和土壤pH值）进行了评估。夏季总的尸体分解是冬季的3至7倍。gravesoil化学最初发生的显着变化后，约320累积度天，无论季节。此外，显著（p
It is well known that temperature significantly affects corpse decomposition. Yet relatively few taphonomy studies investigate the effects of seasonality on decomposition. Here, we propose the use of the Koppen-Geiger climate classification system and describe the decomposition of swine (Sus scrofa domesticus) carcasses during the summer and winter near Lincoln, Nebraska, USA. Decomposition was scored, and gravesoil chemistry (total carbon, total nitrogen, ninhydrin-reactive nitrogen, ammonium, nitrate, and soil pH) was assessed. Gross carcass decomposition in summer was three to seven times greater than in winter. Initial significant changes in gravesoil chemistry occurred following approximately 320 accumulated degree days, regardless of season. Furthermore, significant (p
