Nature’s Biological Early Warning System


Dr Abe V Rotor

 Fresh castings of the earthworm gleam in the early morning.  Watch out if earthworms abandon their burrows and move to higher ground.  A flood is coming!

 Cicada emerges from the soil after a year when its nymphal phase comes to an end, usually at the the onset of the rainy season. The male (uppermost) initiates courting and ultimately mating by singing continuously until a female - or a number of them such as in this photo - are attracted and vie for the lucky Caruso-Valentino in one.

 active during warm nights and the weather is just fine
 Fireflies indicate a pristine environment - clean air and good vegetation


·      1.  When jellyfish come to the surface of the sea there is an earthquake or tsunami coming. It is when the epicenter of an earthquake occurs under the sea that tsunami may  follow. Marine animals as well as land animals can detect minute tremors preceding an earthquake.  Because of this they seek for safe areas usually moving upward shallower waters. (NOTE: Such vibrations are generally imperceptible to humans.  They are monitored by his invention, the Seismograph.)

·       2.   When cockroaches are flying about, there are plenty of fish to catch.  This is not limited to cockroaches.  Other insects do swarm at certain stages or seasons of the year. For example, termites swarm at the onset of the heavy rains (monsoon or habagat); honeybees swarm when the queen bee dies, or when a new queen is produced from an old hive. Gnats or gamu-gamu  swarm when their population shoot up due to freedom from predators. Locusts coalesce and migrate if driven by drought that destroys their source of food. Fish are abundant when there are plenty of insects since insects constitute their main food.

the German cockroach is a quarter in size to its counterpart 
  
·       3.  Sporadic and massive brush fire accompanies dry spell or predicts the coming of the El Niño phenomenon.  Usually it is at the end of the rainy season that grasses like talahib (Saccharum officinarum) and cogon (Imperata cylindrica) reach the end of their life cycle.  In the absence of subsequent rains, these ignite into brush fire, so bad in certain cases that even trees and whole forest burn. Worst scenarios are forest fires as what happen in Australia last 2006, and Indonesia in 2000, the latter sending smoke as far as the Philippines.
    
·       4.  Numerous leafhoppers (Nepothettix spp., Order Homoptera) smashed on the windshield while driving at night on the highway, means there is population buildup of this pest in the area. Leafhoppers attack rice and other crops in their growing and early maturing periods.

·       5.  Ants move into the house for shelter of a coming strong rain or a typhoon. They even carry with them their young and eggs. Oftentimes some of the members of the colony bear wings.  These are soldiers and workers ants which have grown wings in preparation for swarming.

occurs when its population reaches migratory
 level when infestation is heavy.   It is a major
 pest of rice plant.  





 
Leafless kalachuchi (frangipani) is an indicator of extreme dry and hot summer
