Indicator species may provide useful substitute for large scale surveys to monitor biodiversity. Weconducted surveys in the Afro-alpine habitats of the Bale Mountains National Park (BMNP) with theobjective of identifying indicators for the species richness of the raptor guild. Raptors were countedby scan sampling technique from a suitable vintage point. Three classes of 18 sample units groupedaccording to the variability of the moorland ecosystem in the magnitude of process variables importantfor raptor species richness were used in determining the indicator value of species as a function of their abundance concentration and the percentage of species occurrence per sample group. Thisprocedure determined indicator values for all species in the resident raptor community. Comparisonwith randomly expected values demonstrated that only<span> Aquila verreauxii</span>and<span> A. chrysaetos</span>haveindicator values that were significantly larger than the randomly expected values. The species richnessestimated using the abundances of these two species predicted the observed species richness of thewhole community in a linear regression model that explained 66% of the deviance in the data set.Furthermore, the species richness of the community predicted by process variables had correlation of very high significance with that predicted by the indicator species. We have thus identified twoindicator species to a raptor guild of the BMNP and demonstrated that these two species encapsulatedmost of the information regarding the species richness response of the guild to key process variablesin the Afro-alpine moorland ecosystem. Our findings contribute significantly to current and futureefforts of monitoring the biodiversity of the park providing a cheap and quick means of data generation<span>relevant for making management decisions. Hope this helped! :)</span>
The correct option is A.
Horse are herbivores, they eat plants. Large amount of the digestion and absorption of these plant materials occur in the cecum. Horses have enlarged cecum which helps in the digestion process of their food.
The answer is binomial nomenclature , also called binary nomenclature
The Galapagos are considered 'young'because they were created relatively recently in geologic history. The islands are located on the Nazca oceanic plate and were formed by hot spot volcanic activity. As the tectonic plate moves over the hot spot repeated eruptions form islands. The Galapogus islands are thought to be no more than 5 million years old.
Active Transport - requires chemical energy because the process of transport is the movement of biochemicals from areas of lower concentration to higher concentration.
<span>Passive Transport - does not require energy because the process of transport is the movement of biochemicals from areas of higher concentration to lower concentration. </span>
Types of transport:
Active Transport - endocytosis, cell membrane/sodium-potassium pump and exoctyosis
Passive Transport - diffusion, facilitated diffusion, and osmosis.
Types of particles transported:
Active Transport - proteins, ions, large cells, complex sugars
<span>Passive Transport - anything soluble in lipids, small monosaccharides, water, oxygen, carbon dioxide, sex hormone, etc.</span>
