  • Plants currently restricted to south-facing slopes and warm springs (to some extent analogues of future warmer habitats and hot spots of biodiversity) north of their main distribution areas are likely to provide an "inoculum" for rapid colonization of surrounding habitats when climate becomes warmer, although they themselves are likely to be displaced from their current niches by less diverse shrub – thicket communities.

  • The researchers took an inoculum from the hypersaline, alkaline Mono lake and grew it in serial dilutions so that the medium contained progressively increasing amounts of arsenic (As) substituting for phosphorus (P).

  • Viability of inoculum is even more difficult to monitor and maintain which is why we leave this enterprise to those set up to do the job well.

    6: Soil health and plant nutrition

  • Replanting the same species in the same soil year round will serve to increase inoculum for that crop.
