Bacteria and archaea have very different ecology compared to plants. One similarity, though, is that much discussion of their ecological strategies has invoked concepts such as oligotrophy or stress tolerance. For plants, so-called ‘trait ecology’—strategy description reframed along measurable trait dimensions—has made global syntheses possible. Among widely measured trait dimensions for bacteria and archaea three main axes are evident. Maximum growth rate in association with rRNA operon copy number expresses a rate-yield trade-off that is analogous to the acquisitive–conservative spectrum in plants, though underpinned by different trade-offs. Genome size in association with signal transduction expresses versatility. Cell size has influence on diffusive uptake and on relative wall costs. These trait dimensions, and potentially others, offer promise for interpreting ecology. At the same time, there are very substantial differences from plant trait ecology. Traits and their underpinning trade-offs are different. Also, bacteria and archaea use a variety of different substrates. Bacterial strategies can be viewed both through the facet of substrate-use pathways, and also through the facet of quantitative traits such as maximum growth rate. Preliminary evidence shows the quantitative traits vary widely within substrate-use pathways. This indicates they convey information complementary to substrate use.

与维管植物相比,细菌和古细菌的性状维度

与植物相比,细菌和古细菌的生态学非常不同。不过,一个相似之处在于,对它们的生态策略的大量讨论都引用了诸如寡营养或压力耐受性等概念。对于植物而言,所谓的“性状生态学”——根据可测量的性状维度重新构建的策略描述——使全球综合成为可能。在广泛测量的细菌和古细菌性状维度中,三个主轴是显而易见的。与 rRNA 操纵子拷贝数相关的最大增长率表达了类似于植物获得性 - 保守谱的速率 - 产量权衡,尽管以不同的权衡为基础。与信号转导相关的基因组大小表达了多功能性。细胞大小对扩散吸收和相对壁成本有影响。这些特征维度,以及可能的其他维度,提供解释生态学的承诺。同时,与植物性状生态学也有非常实质性的差异。特征及其基础权衡是不同的。此外,细菌和古细菌使用各种不同的底物。细菌策略既可以通过底物使用途径的方面,也可以通过数量性状(如最大增长率)的方面来查看。初步证据表明,底物使用途径中的数量性状差异很大。这表明它们传达了与底物使用互补的信息。细菌策略既可以通过底物使用途径的方面,也可以通过数量性状(如最大增长率)的方面来查看。初步证据表明,底物使用途径中的数量性状差异很大。这表明它们传达了与底物使用互补的信息。细菌策略既可以通过底物使用途径的方面,也可以通过数量性状(如最大增长率)的方面来查看。初步证据表明,底物使用途径中的数量性状差异很大。这表明它们传达了与底物使用互补的信息。
