DESCRIPTION:Join us for this seminar by Oliver Meacock (Sheffield) as par
 t of the Maths in the Life Sciences seminar series (and the online North
  West Seminar Series in Mathematical Biology and Data Sciences in collab
 oration with Liverpool Universities). \n\nTitle: Growth accelerations br
 idge the mechanistic and ecosystem scales in microbiomes\n\nAbstract: Mi
 crobiomes are ecosystems in miniature. Ecological interactions between m
 icrobial populations are generally mediated through their shared chemica
 l environment\, for example via competition for shared nutrients or exch
 ange of secreted metabolites. Understanding how these mechanistic proces
 ses shape the ecological properties of communities is a fundamental prob
 lem that remains largely unresolved. I will present new results that pro
 vide a general link between the mechanistic and ecosystem perspectives b
 y assuming that growth accelerations\, rather than rates\, are the quant
 itative basis of ecosystem dynamics. The resulting equations reveal the 
 common origins of temporal\, spatial and environmental dependencies of i
 nteraction strengths\, resolve how strong mutualisms can remain stable\,
  and show how to achieve pairwise additivity of interactions without res
 orting to higher order terms. I will also discuss the implications for o
 ur interpretation of the parameters of the generalised Lotka-Volterra eq
 uation\, which display counterintuitive trends as mechanistic processes 
 (such as metabolite secretion rates) are varied. These findings resolve 
 the long-standing challenge of connecting niche theory to coexistence th
 eory\, with implications for a broad range of ecological and evolutionar
 y questions.\n\nThe talk will be also be streamed via Teams\, please con
