Thanks for changing the title spook
Hope you enjoy JJ and Bishop
I decided to put up the first round, It wont be too difficult
and then depending on how many mites find it ill decide how long it stays open
The first question will also have a bonus part for an extra 2 points
but there will be no penalty if the bonus part of the question is unanswered or answered incorrectly.January: Round 1
1. When startled by predators a springbok will launch into a spectacular display of pronking; Legs stiff, feet close together, head down and back arched with white dorsal crest displayed. It would be much faster for the antelope to simply run away rather than pronking because although the jump can clear 3m they attain hardly any horizontal distance. So why then do they pronk?
And for the bonus part to the question: The signal portrayed by the pronking is interpreted differently by different predators, how would a cheetah and spotted hyena differ in the messages received in terms of their hunting strategiesSpringbok may pronk for a number of reasons, such as when searching for water, after a disturbance and according to some references even before a break in weather . Specifically related to the threat of predation pronking is what is referred to as an honest advertisement of condition. In other words the weaker, older animals cannot pronk as high or as athletically as animals in their prime due to the demands of the activity. The behaviour is performed for two reasons, the first has an alert function in which the rest of the herd is alerted to potential danger and the second is to avoid predation. Thus pronking is a display of fitness. Now in the bonus question the specifics of the anti predator behaviour are more specific. Cheetah and spotted hyaena have very different hunting strategies. the cheetah is a sprinter and will only cover short distances while the spotted hyaena is an endurance predator and will cover many kilometres, tiring out its potential prey. This means that to them the messages they receive from the pronking springbok will be quite different. A cheetah relies on stealth and it's ability to stalk its prey and then run in. If it is detected before it begins the chase and the pronking is initiated the cheetah will usually abandon the hunt as its chances of a surprise attack have been lost. Pronking however sends a very different message to the hyaena, they will not simply give up the chase and in this case the pronking will indicate to them which is the weaker animal and the one they are more likely to be able to catch as well as which will not be able to run for a long time.
2. Along our coast their are three mains types of seaweeds, brown (phaeophyta), green (chlorophyta) and red (rhodophyta). Each one of these groups is characterised by a suite of different types of chlorophyll and/or accessory pigments and due to this can be found at different depths in the tidal areas. List the position in which they would be found from the most shallow (nearer to the surface) to the greatest depths.Here I was looking for, Chlorophyta, Phaeophyta and then Rhodophyta. Chlorophyta contain chlorophyll a and b and thus have the characteristic green colour as in land plants. Brown seaweed or kelp. Next time you are at the coast have a look at the brown seaweed, it will often have black ripples or bumps on it and that is the accessory pigment, fucoxanthin which also gives it the brown colour. Kelp has chlorophyll a and c. Rhodophytes are more specialised and contain blue and red pigments called phycobylins as well as chlorophyll a . Green seaweed is always green and as such must always be near to the surface of the water as it can only photosynthesise with the wavelengths of light at the long end of the spectrum and hence the light that cannot penetrate to great depths. Phaeophytes are not always brown and can be blue which would be the deeper water forms and the same with rhodophytes, they can appear green, purple, red and brown. Basically the deeper you move in the water the less the amount of light that is able to penetrate, so at greater depths only the short waved radiation can reach, such as the violet and blue light which can then be utilised by the brown and mostly the red seaweed to photosynthesise.
The general rule of where they can occur in the water column is correct but they can also be found at the same level and their position may also depend on other factors such as water clarity or turbidity as this directly effects the amount of light that is able to penetrate the water due to scattering of the light. The wave action can also have an effect, an area with turbulent wave action will have a much less pronounced gradient of separation because the light cannot penetrate as well.
3. Rhino's, both black and white deposit their faeces in middens. This attracts a large number of dung beetles of many species. You will be familiar with those you see rolling their balls away from the midden but not all do this as some make their homes underneath the midden to reproduce. There is one animal that frequently digs inside these middens to obtain dung beetle grub. What animal am i talking about? honey badger, or ground hornbill
4.What is the obvious difference in appearance between a male and female mosquito?The proboscis of the male is much more elaborate and has a feathery like appearance while the females is more plain, almost smooth .
5. In the animal kingdom there are often close associations between pollinators and the plants they pollinate. What group is the primary pollinator of Adansonia digitata
?Bats (megachiroptera) are the primary pollinator of the baobab.
