DESCRIPTION:Speakers: \nGroup Work 1\n**Acoustic monitoring**\nAnimals use
  sounds in different behavioral context\, including communication\, echolo
 cation\, sexual display and territoriality. Over the last decade\, the use
  of the natural sounds has emerged as an increasingly important and widely
 -used tool for studying wildlife and habitats. Among the current uses of a
 coustic monitoring are the study of species and populations\, animal behav
 ior\, the acoustic communities and biodiversity. Based on acoustic records
  obtained in nature\, we will attempt to examine how the frequency spectru
 m varies throughout 24 hours of recording\, taking into account the differ
 ent zoological groups involved in an acoustic community in Western Cuba. I
 n addition\, we are going to examine the dynamics of a chorus of a Cuban e
 ndemic frog\, analyzing how their spectral and temporal patterns are distr
 ibuted during the peak of nocturnal activity of the species. To complete t
 his task\, students will receive a theoretical part on bioacoustics and ec
 oacoustics topics\, while the practical component includes from obtaining 
 recordings in the field to the processing and analysis of sounds using spe
 cialized software and programming exercises.\n*Roberto ALONSO (University 
 of Havana\, Cuba) Luís Felipe TOLEDO (UNICAMP\, Brazil)*\n\nGroup Work 2\
 n**Quantifying air-travelling biofluids**\nWe will visualise and quantify 
 the motion of model medical fluids resembling nasal sprays\, as they move 
 through free space and inside a 3D-printed model of a human nasal cavity. 
 The idea is to quantify how different administration methods are able to r
 each target regions within the nasal cavity. In addition to experiments\, 
 computer simulations will help understand the process and study experiment
 al configurations unavailable in practice.\n*Daniela MARTINEZ-ORTIZ\, Laza

 oup Work 3\n**Quantifying microbial ecosystems I**\nGenerally speaking\, t
 his experiment will measure the formation and dynamics of redox gradients 
 in natural microbial ecosystems as they relax to steady state. This group 
 will focus on the measurements of the diverse timescales over which microb
 ial metabolism at depth is coupled to temporal variations at the surface\,
  for example the day night cycle. This group will build a device to contin
 uously record these dynamics\, using harmless microbial species. \n*Alex P
 ETROFF(Clark University\, USA)*\n\nGroup Work 4\n**Quantifying microbial e
 cosystems II**\nGenerally speaking\, this experiment will measure the form
 ation and dynamics of redox gradients in natural microbial ecosystems as t
 hey relax to steady state. This group will focus on the motion of the cons
 tituent microbes. The participants will use microscopy to visualize the mo
 tion microbes as they form fronts that stabilize redox gradients. This gro
 up will additionally seek to enrich bacteria that are capable of navigatin
 g these gradients.\n*Alex PETROFF(Clark University\, USA)*\n\nGroup Work 5
 \n**Ecology and coexistence in a chemostat**\nIn this experiment\, the stu
 dents will grow two E. coli strains with obligate mutualistic interactions
  in a chemostat. The coexistence of the two strains will be manipulated by
  changing experimental conditions (dilution rate and medium composition).\

  experiment**\nThis module will engage students with measuring mutation ra
 tes in expanding yeast populations.         This is the classic "Luria-Del
 bruck" experiment which is also a pioneering historical example of interdi
 sciplinary collaboration in quantitative biology. We will introduce the ma
 thematical framework and population dynamics models needed to approach the
  problem\, along with relevant results from the literature. Students will 
 have the opportunity to perform the experiment themselves using yeast\, me
 asuring the rate of emergence of resistance mutations and testing scenario
 s of induced versus spontaneous phenotypic transitions. This will involve 
 growing cells in multi-well plates\, applying a stress such as phages or d
 rugs\, and quantifying the fraction and abundance of surviving colonies. B
 y using stochastic models and model-selection strategies\, students will b
 e asked to answer key questions and compare different resistance targets. 
 Overall\, this module provides students with a hands-on understanding of m
 utation rates and population dynamics.\n*Giorgio TALLARICO (IFOM\, Italy)
