adapt to changing conditions

: appropriately respond to dynamic contexts.

creatures are constantly adjusting, trying to reach a steady comfortable relationship with their environment. to do so, an organism must be intimately aware of and adapt as needed to ever-changing conditions in their locale. some changes are significant enough to warrant a shift in behavior. in an organism does not respond to those shifts, an individual will not survive, and if this occurs on a species-wide scale, the species itself will not survive natural selection. adaptation is a long-term alteration in strategy based on the degree on change in context. 

to do so life...
maintain integrity through self-renewal
: persist by constantly adding energy and matter to heal and improve the system

systems tend to move towards disarray unless energy is added to the system. this is also true for living organisms; necessary functions would falter without a strategy to continuously add energy and material to the system. to avoid this, living systems actively turnover the parts of the system. from molecules up, systems are continuously disassembled and remade with this proactive approach to maintenance. thus, a system can guarantee a level of performance instead of waiting for a part to fail and then replacing it. self-renewal is also a way to incorporate changes within a system. if changes are programmed into the continuous turnover of the parts and pieces, the whole system can be shifted, to the point of adaptation, without gaps in overall functionality.

life continues to regenerate even the "good" parts, allowing them renew to new conditions.

greater long-tailed bat
choeroniscus periosus


genus: panthera
family: felidae 
order: carnivora
class: mammalia
phylum: chordata
kingdom: animalia 


the greater long-tailed bat is found in colombia and ecuador. like all bats, its wings are thinner than those of birds so they can maneuver quickly and more accurately. the skin on their wing membranes has more elasticity and so can stretch much more than other mammals. their wings are more delicate, so can rip easily. however, the tissue if the bat`s membrane is able to regrow, such that small tears can heal quickly. 

compensar business center


          architect: motta y rodriguez 
          environmental consultant: arch. & bioclimatic
          location: bogota, colombia

  
  

the compensar businees center restores the accumulated thermal inertia to the environment through the ceiling. this process self-renews the air in the building. 
embody resilience through variation, redundancy and decentralization
: maintain function following disturbance by incorporating a variety of duplicate forms, processes, or systems that are not located exclusively together

resilience is the capacity of a system to maintain function following a disturbance. in short, is is the ability to recover after adversity. the capacity for resiliency, from bodily organs to ecosystems, often depends on the interconnectedness and functional diversity of multiple systems. when on system fails or does poorly, others can step in to compensate, either briefly or long term. as the nature of the disturbance is unpredictalbe, variation in strategies allows for some to endure while others may be lost; dedundancy permits the remaining to continue, despite losing some; and decentralization ensures that independent of where the disturbance falls, not all will be subject to its impacts.

variety - what kind of disturbance
redundancy - how dramatic the disturbance
decentralization - where the disturbance

atlantic banded octupus
octopus zonatus


genus: octupus
family: octopodidae
order: octopoda
class: cephalopoda
phylum: mollusca
kingdom: animalia 


the octopus primary defense is to hide, either to not be seen at all or not be detected as an octopus. they have a secondary defense, for once they have been seen by predators, been the most common a fast escape. if they can`t, their third option are the use of ink sacs, camouflage or autotomising limbs. 

octopuses also have three hearts: two branchial hearts that pump blood through each of the two gills, and a third one that pumps blood through the whole body. they have a complex nervous system, only part of which is located in its brain. two-thirds of its neurons are found in the nerve cords of its arms, which have limited functional autonomy. 

incorporate diversity
: include multiple forms, processes, or systems to meet a functional need

diversity is also a method b which new opportunities are found and explored. given a pool of traits that are all slightly different though genetic diversity, population trends shift towards those individuals with traits more suited to the environment at that specific time. systems are nos predictable, but even commonplace occurrences in a system are better handled with options. without even taking into consideration unforeseen events or adversaries that challenge survival, and individual often manages challenges more efficiently when it can respond by choosing among several available options, be they genetic or just diversity in strategies and behaviors. 

the more diversity you have, better is your ability to adapt to the diversity around you.

blue land crab
cardiosoma guanhumi


genus: cardiosoma
family: gecarcinidae
order: decapoda
class: malacostraca
phylum: arthropoda
kingdom: animalia 


the blue land crabs have multisensory control (visual system, canal organs of the statocysts and leg proprioceptors) of eye movements to increases the range of velocities to which they can respond and bring the control system into the range where visual feedback can provide accurate compensation for body turns. the presence of all three senses can act directly on the gain of the visual system, increasing it by a factor of up to five, so that it`s closed-loop gain approaches unity. multisensory control produces good compensation for body turns and provides effective compensation under a variety of conditions, such as a featureless environments and low light intensities, where visual mechanisms acting alone might have been insufficient. because they are most active at night, such multimodal control might be particularly significant for detection of predatos. 

they involve three different sensory systems to simplify the complex visual imput that they receirce to that the images that reach the eye can ve more readily interpreted. this input comprises both stationary and moving objects of different sizes and in different parts of the visual field, all influenced by the crab`s own movements which involve rotation as well as translation.

manizales pavilion


                       architect: simon velez
                       location: manizales, colombia



the pavilion built by simon velez and marcelo villegas was built  to prove that the structure, which has a poured concrete roof and a concrete terrace, could be engineered to withstand extreme weights and tensions. two pavilions were built. The first one was built in manizales to prove that this large structure could be built to the exacting building code of the german government. after several tests including stress and weight deformation, it was concluded that this method of building exceeded the standards required in germany.  the most notable achievements of bamboo structures like the ones pictured below is the ability to endure earthquakes.

bamboo is a renewable resource and when used with other materials such as concrete, rebar and other woods, can bear the required loads and sometimes surpasses them. years ago it was thought as the bamboo as a "material of the poor", architect simon velez has dedicated years to study and harness this material.
