Answer:

Hypothesized causes for the declines include habitat destruction (the most obvious cause), climate change, pathogens, introduced exotic species, pollution, and increased UV radiation. These agents may act alone or in combination to contribute to the decline of amphibian populations.

Answer:

A few causes for the declines in the Amphibian population include habitat destruction, climate change, introduced exotic species, germs or pathogens, pollution increases, and increased UV radiation. These things may act alone or in combination to contribute to the decline of amphibian populations.

Here are 9 factors that have  impacted the amphibian population

Insects are attracted to lights making them scarcer within the amphibian habitats.

Habitat modification.

Habitat fragmentation.

Pollution and chemical contaminants.

Ozone depletion, ultraviolet radiation and cloud cover.

Disease.

Introduced predators.

Increased noise levels.

Where can you observe environmental changes that are forcing adaptation?
Helen [10]

Answer:

Description

Since its inception, life on earth has had to adapt to changing environmental conditions - this represents a driving force of evolution.

This module examines how organisms detect and respond to changes in their environment, and reviews the different behavioural, physiological and molecular mechanisms underpinning environmental (stress) adaptation.

Understanding these organism-environment interactions forms the very foundations of ecology. Examples are provided from a range of organisms, but a specific focus is given to terrestrial invertebrates (insects) and plants.

The term “environment” covers a broad spectrum of spatial scales, from changes occurring at the cellular level, to large scale geographic differences between major climatic zones (polar, temperate and tropical).

The process of “change”, and adaptation to these changes, will in turn be discussed across a broad spectrum of timescales. These include:

The requirement for rapid adaptation to potentially dramatic shifts in environmental conditions, e.g. when a parasite first enters its host

Longer-term changes and adaptations across seasonal timescales, e.g. hibernation/insect diapause

Adaptation on an evolutionary timescale, e.g. the ‘Red Queen’ hypothesis, across scenarios of past environmental changes, and extending out to current predictive climate change models

The main aims of this module are to provide students with information, guidance, and access to resources, that will allow them to:

Gain an in depth understanding of how organisms respond and adapt to changes in their environment.

Recognize that the term “environment” covers a continuum of spatial scales from molecular environments within cells, to broad-scale geographic environments and climatic zones.

Appreciate that adaptation to environmental change for an individual organism is transient and occurs across a temporal spectrum of seconds to seasons. For species, adaptation is long-term, but not fixed/permanent, and occurs across a timescale of generations.

Interpret the potential impact of climate change on species, communities and ecosystems. Specifically with respect to how the rate of environmental change may limit effective adaptation, and so result in changes in species distribution and abundance patterns

Become effective independent learners, capable of analysing and interpreting the scientific literature to help formulate and express their own ideas

A child has been in the hospital for several days for treatment of severe vomiting related his hiv-positive status. which assess
NeX [460]
No lesions in the mouth and throat
Weight increase of 1 lb over 3 days Correct
Temperature change from 100.2° F to 99.2° F
Capillary refill slowing from 2 seconds to 3 seconds
Weight increase of 1 lb (0.45 kg) over 3 days
Rationale: Vomiting results in fluid volume deficit. The most accurate method of evaluating fluid volume increase (the desired outcome) is weight. A temperature decrease is not reflective of fluid volume increase. Increasing capillary refill time is indicative of a fluid volume decrease, not an increase. The absence of mouth ulcers would allow the child to drink without pain but does not reflect a fluid volume increase.
