Since Darwin first wrote on the subject in 1871, sexual selection has been generally accepted as one of the basic facts of biology. The evidence in its fav... AJ BATEMAN - 《Heredity》 被引量: 6807发表: 1948年 An Ecological Model of Female-Bonded Primate Groups A model suggests that fema...
The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled", or held constant, in the control group. A single ...
in this case, fossils. It can take place in the water column even during the life of the organism, in the immediate post-mortem interval when the fossil becomes part of the sediment components on the seafloor, or during burial in the sediment, which – on longer time scales...
Fig. 4: The pyruvate to butyrate operon is maintained over evolutionary time in host-associated bacteria. aCartoon of butyrate biology: the short chain fatty acid is produced by members of the mammalian microbiome and is a key energy source for the host colonocytes. The anaerobic environment of...
The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest ...

Mitogen-activated protein kinases (MAPKs) preserve cell homeostasis by transducing physicochemical fluctuations of the environment into multiple adaptive responses. These responses involve transcriptional rewiring and the regulation of cell cycle transit
As developing tissues grow in size and undergo morphogenetic changes, their material properties may be altered. Such changes result from tension dynamics at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms controlling the ph
(HAT). An enzyme that adds acetyl groups to histones. Many HATs function as co-activators. HISTONE A family of small, highly conserved basic proteins, found in the chromatin of all eukaryotic cells, that associate with DNA to form a nucleosome. CHROMATIN IMMUNOPRECIPITATION (ChIP) ASSAYS ChIP ...
