At first order, extremes in temperature constrain microbial diversity in chemosynthetic hot springs10,11.
We use a mixture of mathematical models and known allometric relationships to examine whether host and parasite life histories constrain the diversity of parasite species that can coexist in the population of any host species.
Thus, the bulge of the EPLP 11-mer has been postulated to constrain TCR diversity.
The endophyte manipulation trials, involving endophyte removal from E+ seeds by heat treatment, as well as inoculated E- seedlings, also allowed us to examine whether partner specificity or compatibility constrain the diversity of established endophyte symbiosis.
Interspecific hybridization can either promote or constrain biological diversity.
Interestingly, a recent comparative analysis across 34 host species also demonstrated non-random clustering of RV reservoirs on the carnivore phylogeny, highlighting the potential for host phylogeny to constrain the diversity of RV reservoirs [ 18 ].
Biophysical properties of neurons become increasingly diverse over development, but mechanisms underlying and constraining this diversity are not fully understood.
However, we found temperature was an important factor in constraining bacterial diversity and composition (Fig. 2b; Additional file 1: Figure S1), though only a minor variation was directly explained by temperature (Table 2; Fig. 4).
We find that a pattern of local extinction and recolonization constrains total diversity and group differentiation and attenuates the rate of cumulative change per transmission event.
This could lead to a genetic mismatch between the fungus and the host, thus destabilizing the symbiosis and constraining the diversity of successful genotype-genotype combinations of the vertically transmitted endophytes and the host grasses.
