First, we measured the ATP retained byover time when cultured at low (0.1 mM) and control (22.2 mM) concentrations of glucose and obtained the chronological change in ATP concentrations. Then, by comparing these
While the exponential equation is a useful model of population dynamics (i.e., changes in population numbers over time), in the real world we are not swimming in bacteria, or Paramecium, or slime moulds. That is, something happens to stop the growth of organisms, be they cells in t...
gondii infection in dasyurids (65 wild-caught, 103 laboratory reared), using histopathology without confirmatory testing, found the widest dissemination of organisms consistent with T. gondii in two fat-tailed false antechinus (Pseudantechinus macdonnellensis) with leukaemia (Attwood and Woolley, 1973...

Our findings concerning the green sandpiper adds to the growing literature demonstrating how engineering by beavers facilitates a myriad of organisms (Stringer and Gaywood, 2016), sometimes even whole species communities (Nummi and Holopainen, 2014, Romansic et al., 2020). From the point-of-view...
This drives the final resolution of the conflict: the irreversible loss of sexual reproduction and the complete dependence of the host on its symbiont. Conclusions This study shows that dependence among organisms can evolve rapidly due to the resolution of the conflicts between cytoplasmic and nuclear...
o The movements brought populations of certain fishes and marine organisms into contact with one anotherfor the first time.o The movements transferred populations of fishes and other marine animals between the Pacific and Atlantic Oceans.o The movement created conditions that al lowed water to flow ...
Here, we provide strong and clear evidence that seascape imposes major constraints on the demographic and genetic structure of a cetacean, and thus on its dispersal. This finding is of general interest in the context of climate change and habitat fragmentation for marine species, as ecosystems in...
Diversity and determinants of meiotic recombination landscapes. Trends Genet. 35, 359–370 (2019). This review considers the difference between patterns of DSBs and crossover events along the genome across many organisms and discusses the molecular determinants that govern variation in recombination ...
(SNVs/kbp, 0–65) with a different SNP calling approach30. The pN/pS results show that these sedimentary cold seep populations are under purifying selection, suggesting the possibility that these organisms have reached an adaptive optimum in this relatively stable environment, and maintain this by...
