Abstract Large carnivores, including the grey wolf ( Canis lupus ), play an important role in carbon cycle through modifying behaviour and population of wild herbivores. carnivores have been eradicated from much their former range are now absent UK, contributing to increased herbivore populations, which can prevent natural regeneration trees woodland. A reintroduction wolves UK could reduce deer populations associated browsing tree saplings, but potential impacts on woodland expansion sequestration not assessed. Here we estimate impact a Scottish Highlands red native colonisation sequestration. We use Markov predator–prey model that would lead 167 ± 23 wolves, sufficient below 4 km −2 , threshold at assume be sufficiently suppressed enable trees.

ABSTRACT Human activities have caused significant changes in animal abundance, interactions, movement and diversity at multiple scales. Growing empirical evidence reveals the myriad ways that these can alter control animals exert over biogeochemical cycling. Yet a theoretical framework to coherently integrate predict when how controls cycling (i.e., zoogeochemistry) change is currently lacking. We present such general provides guidance on linking mathematical models of species interaction (network theory) organisms non‐living materials (meta‐ecosystem account for biotic abiotic feedback by which illustrate apply develop predictive specific ecosystem contexts using case study primary producer–herbivore bipartite trait network boreal forest ecosystem. further discuss key priorities enhancing model development, data–model integration application.
