Peer viewed about animals and ecosystem
“Globalization is often associated
with deforestation, but its impacts on forest recovery are less known” (Susanna
B. Hecht). This article
analyzed socioeconomic data, land-use surveys, and satellite imagery to monitor
changes in woody cover in El Salvador from the early 1990s to the present. "Even where rural
population density exceeded 250 people per square kilometer, they documented a
22% increase in the area with more than 30% tree cover, and a 7% increase in
the area with more than 60% tree cover," (Susanna B. Hecht). The results may seem surprising to many conservationists who
most often associate globalization with deforestation and degradation of
old-growth forests. Hecht and Saatchi argue that “the roles of economic and
social trends like globalization and remittances on forest recovery have so far
been overlooked.” Globalization and Forest Resurgence: Changes in Forest

Diarrhea Outbreak during U.S. Military Training in El Salvador (click here)
This article was writing in order to show how animals like flies are affecting people with diseases such as diarrhea it is related to the environment because people are killing frogs and toads that are in charge of keep the environment clean from the excesive number of insects misquotes and zancudos all of this disturbance that are occuring is because we are taking one animal from a place and the balance in habitat have been broken.

Ecosystem of Jocoaitique Morazan
Jocoaitique is a municipality in the department of Morazán, El Salvador. According to the official 2007 census, has a population of 2,877 inhabitants.The municipality covers an area of 51.85 km ² and has a header altitude of 680 meters.
Jocoaitique is surrounding by splendorous mountains it is located in a place where the dry season is pretty much hot and the wet is really windy the larger ecosystem here is located along the Arauter river a place that contribute to many habitats; starting with insects and ending with big mammals such as tigers. It place is considerate a protected area of the municipality and is located at 30 minutes walking from the city. It has nice trails and enormous variety of plants and birds leave there. Aruter river is conciderated one of the most important virgin rivers of all department and country.

Lab 6 Evolution and Adaptations
Explain adaptive
radiation and how the different paper forms made by the “finches” helped or
hurt that particular “finch species”.
Adaptive radiation “is when one species, due to
a sudden change in environment, quickly evolves into many offspring species”.
Adaptive radiation occurs when a species is dislocated to a
different location than it has typically inhabited, and has to adapt quickly or
die out. The location may not have the same ecological set-up as the place that
the species was used to
A classic example of adaptive radiation is Darwin's finches.
“Adaptive radiation was basically discovered by Charles Darwin when he saw the
finches on the Galápagos Islands had the same basic features (hence,
were descendants of a parent species) but had adapted to different
environments”. As individuals from the mother species moved to different areas
of the islands, some of them had the need to smash rocks to get food, so birds
with big, tough beaks were selected for. Others had the need to dig for bugs,
so long, skinny beaks were selected for. The needs of the birds selected for
their traits over generations, giving them different phenotypes.
Phenotypes:
“Phenotypes as relating to what the birds had to eat (hence, what beaks the early birds were selected for because of what they were able to eat)”

Explain how
behavioral adaptations may lead to genetic changes in a population.
“Genetic change is what occurs in a population when natural
selection acts on the genetic variability of the population;
moreover, some mutations may create genetic variation that will lead to
differing characteristics of offspring and hence abet adaptation.”
By this means, the
population adapts genetically to its circumstances. Genetic changes
may result in visible structures, or may adjust physiological
activity in a way that suits the changed habitat. The organism has to be
adapted over time for example at the time that climate change is occurring the
organisms are doing evolution and some are disappeared for this reason they are
creating a new genetic changes one of them is When a habitat changes, the most
common thing to happen is that the resident population moves to another locale
which suits it; this is the typical response of flying insects or oceanic
organisms, who have wide (though not unlimited) opportunity for movement

A species that has a behavioral adaptation that may allow
its predator not to be able to eat it or find it. Explain what this behavioral
adaption is
 |
Figure 1 National Geographic
|
Chimpanzees work together with closely
related kin to protect their territory. Defending territory from rivals
(known as territoriality) is a learnt adaptive behavior performed by several
ecological species.
A species that has a physical
characteristic that allows it to survive in cold weather.

Arctic Land Mammals
It is vital for a mammal, being a ‘warm-blooded’ vertebrate, to keep warm
in order to maintain its body at a constant temperature.

A cricket crawls toward the leaves of a Venus flytrap that can shut
tight, trapping the insect.
An example of mutualism in nature
 |
Figure 4 National Geographic
|
Clownfish and a sea anemone; the sea anemone would protect the
clownfish from predators by using its tentacles to paralyze with discharged
cynoblasts(shocks) and then ingesting them. Clownfish would defend the anemone
from Butterflyfish which eat the anemone.
An
example of mimicry in nature
 |
Figure 5 Dumage
|
Insects are common examples of mimicry. Insects can be so blend with
their surroundings that sometimes we can not recognize them. Some insects
can have the appearance of twigs, leaf, bark, wood and some may simply be the
same color as their habitat.
This insect looks like a dried leaf, and the
shape and color.This is a great camouflageagainst predators who will go next to
him thinking he is the most common leaf.

Orchids. (Orchidaceae); this type of plant can be found in various parts
of the world, in our country can also be viewed Orchid species diversity in
almost any area of the country. This is because most orchids have adapted to
different climates and habitats.
