求翻译以下几句英语，动物福利方面的论文里的。

Elevations in DOA values above this baseline were almost entirely the result of thermal stress (95%) and were concentrated in specific vehicle locations.
高于该底线的死亡率增高几乎全部是由于高温压迫所致（95%）且集中在车辆的特定位置。
Nijdam et al. (2006) reported that 89.4% of dead birds (DOA) exhibited macroscopic pathological lesions. Infectious disease states were the main cause of lesions (64.9%) followed by heart and circulation disorders (42.4%) and trauma (25%).
Nijdam et al. 【可能是人名或刊物】2006年报道称，89.4%的死亡鸟类（送达前死亡）显示有明显的病理损伤。传染病是造成损伤的主因（64.9%），其次是心脏和循环系统紊乱（42.4%）及外部创伤（25%）。
However, conditions of transport, especially thermal conditions, were not discussed in detail. Birds affected by any of these pathologies may be more susceptible to thermal stress and thus may succumb when exposed to thermal conditions that would not adversely affect healthy birds.
然而，运输条件，尤其是温度条件，并未详细论述。鸟类受任何这些病理的影响而死亡的情况也许比受温度压迫影响（因接触高温条件）而死亡的情况更容易让人接受，因为高温条件对健康鸟类并无不利影响。
Thus, it may be assumed that levels of mortality or DOA vary widely depending upon many factors including season, geographical location, journey length, size of bird, stocking density, health status, vehicle design and slaughterhouse design and practice.
因此，可以假定，因多种因素导致的死亡率大不相同，包括季节、地理位置、运输距离、鸟类大小、装载密度、健康状况、车辆设计以及屠宰室设计与操作等。

希望对你有所帮助。
