Autonomous multi-drone aerial surveys of Antarctic penguin colonies（图）
Autonomous multi-drone aerial surveys Antarctic penguin colonies
2020/11/13
Scientist Mac Schwager at Stanford University, an aeronautics and astronautics researcher, learned that biologists were seeking a better way to image a large penguin colony in Antarctica. Schwage...
The rewards of restraint in the collective regulation of foraging by harvester ant colonies
collective regulation harvester ant colonies
2015/12/10
Collective behaviour, arising from local interactions1
, allows
groups to respond to changing conditions. Long-term studies have
shown that the traits of individual mammals and birds are associated...
Evidence of mud diapirism and coral colonies in the ionian sea (central mediterranean) from high resolution chirp sonar survey
Ionian Sea CHIRP sonar echo character
2015/9/7
A chirp sonar survey in the Ionian Sea investigated the Calabrian margin, the Calabrian accretionary wedge, the Taranto Trench and the Apulian foreland. Shallow tectonics structures have been related ...
Drag coefficients for single coral colonies and related spherical objects
scleractinian corals drag force coral hydrodynamics
2014/4/1
Flows over and through coral canopies and isolated coral colonies are sometimes approximated using
arrays of spheres and cylinders, which may not adequately represent the effects of their complex geo...
Supplementary information for "Selective sweeps in growing microbial colonies"
Supplementary information Selective sweeps growing microbial colonies Populations and Evolution
2012/5/2
This is supplementary information for arXiv:1204.4896, which also appeared in Physical Biology 9, 026008 (2012). Main text abstract: Evolutionary experiments with microbes are a powerful tool to study...
Selective sweeps in growing microbial colonies
Selective sweeps growing microbial colonies Populations and Evolution
2012/5/2
Evolutionary experiments with microbes are a powerful tool to study mutations and natural selection. These experiments, however, are often limited to the well-mixed environments of a test tube or a ch...
Responses to iron limitation in two colonies of Stylophora pistillata exposed to high temperature: Implications for coral bleaching
Stylophora pistillata Responses coral bleaching
2014/4/8
Exposing the coral Stylophora pistillata to seawater depleted in available iron by complexation with the strong
chelator desferrioxamine B reduces the photosynthetic efficiency and alters the pigment...
Experimental and theoretical study of processes of formation and growth of pearlite colonies in eutectoid steels
Experimental theoretical study of processes of formation pearlite colonies
2010/11/25
We describe our optical and electron-microscopy observations of pearlite structures in eutectoid steels which seem to imply that the mechanisms of formation of pearlite colonies in these steels differ...
Metabolism and resources of spherical colonies of Nostoc zetterstedtii
Metabolism resources Nostoc zetterstedtii
2014/4/18
Constraints imposed by the spherical form and gelatinous matrix of centimeter-thick colonies of the
cyanobacterium Nostoc zetterstedtii on its functional properties were tested by examining the scali...
Bioavailability of iron to Trichodesmium colonies in the western subtropical Atlantic Ocean
iron Trichodesmium colonies western subtropical Atlantic Ocean
2014/5/22
Trichodesmium provides new nitrogen (N) to marine surface waters via N2 fixation, a process that requires a substantial amount of iron (Fe). Organic ligands in seawater that bind Fe could either incre...
Photoinhibition in shallow-water colonies of the coral Stylophora pistillata as measured in situ
shallow-water Photoinhibition
2014/5/21
Continuous pulse amplitude–modulated (PAM) fluorescence measurements were performed in situ under natural
irradiances for colonies of the coral Stylophora pistillata growing in shallow (2 m) an...
Effects of photosynthesis on the accumulation of Mn and Fe by Phaeocystis colonies

2014/6/9
The significance of Mn and Fe accumulation by Phaeocystis colonies and its control by photosynthesis were
investigated by performing incubation assays with radiotracers (
