For example animals behavior can be group composition, social interactions and focal animals behavioral observations. For example population biology can be life span, birth rate, mortality rate and abundance estimates. Population must be definable because at least two and preferably more animals. Should be made to try to ensure that all animals have an equal probability of being captured during any one sampling. Should be made to try to ensure that all animals have an equal probability of being captured during any one sampling occasion. Better chance to capture the animals with a high probability of bias caprure number of recaptures up and leads to underestimation of population size. Identify an invidual animals is possibly, because we photographing sample of animals at deferent places - > enable movement and migration. It can also provide information on the identity unit in the population. ...read more.


GPS GPS need for accurate time setting on the camera. Before each work a taking a GPS must be clearly recognizable time. After sorting the photos, the timing of the time use camera adjusted for the errors of the difference GPS. Whale - watching ship The ship is required to obtain high-quality photos. We could hardly the photographs from the shore and taking pictures whales at a distance of about 2 km. Ship should be stable, should not be too much sway. Paper, pen Paper and pencil needs to record information on the incidence of species, time of occurrence. Sliu�� then to improve the identification of species on photographs. CRITERIA SELECTION PHOTO Criteria selection are mainly hight quality. When the poor quality are of the wrong kind of recignition, movement atc. When the right quality are possibility of identifying animals. We can provide hight resolution. When the quality resolution are well recognizable characters. Photo can have full frame images of identifity features. Another necessity is that the images were all for a good identification of elements. Other criteria is for flukes straight behing. Flukes should be as straight as you can see in the picture, no shot. For body and dorsal fins can left side and perpendicular to the animal. In the examining the body and the dorsal fi should be shot with left side and perpendicular to the animals (90� angle). The photo is also important to spread the light. ...read more.


WHITE - BEAKED DOLPHINS White - beaked dolphins was observation by 3 encounter (1.9.2009, 2.9.2009 - morning, 3.9.). Encounter 1 IMAGES 16: ENCOUNTER 1 - PHOTOGRAPHED 1.9.2009, 15:10 This is excelent photo. It is hight quality, resolution, good shot dorsal fin. It is good recognizable invidual marks in hill dorsal fin. Encounter 2 IMAGES 17: ENCOUNTER 2 - PHOTOGRAPHED 2.9.2009, 11:04 This is good focus. It isn�t hight quality, resulion. It is good shot dorsal fin. It is possible determination invidual. Encounter 3 IMAGES 18: ENCOUNTER 3 - PHOTOGRAPHED 3.9.2009, 18:35 This is good photo. It is good quality, resolution, good shot dorsal fin. It may better lights and resolution, but it is possible determination. DEDUCTION Methods photo - id uses for biological observations, ecology, population estimates. Resulting photograph grading high quality to low quality and species dependent. Errors can occur in identifying marks. Errors in data collection and analysis. During our observation we see 3 patertns animals - humpback, minke whale and white - beaked dolphins. We take around 900 photo, with which we chose good photo, on dolfin was 33, on humpback whale - fin was 157 and fluke 83, on minke whale was 9. From this photo we chose best photo for each peterns and each day. The best photo on humpback is photo of 2.9.2009 - 15:23. The best photo on minke whale is photo of 27.8. 2009 - 14:46. The best photo on white - beaked dolphins is photo od 1.9.2009 - 15:10. ...read more.

  2. Do patients with chronic low back pain have proprioceptive deficits in their lumbar spine?

    Alternative methods have produced significant results, including O'Sullivan (2003) and Mientjes (1998) which suggests that the method of measuring proprioception has a vital effect on the results. Proprioception is largely based on joint position sense and therefore balance is closely linked, as once the bodies' centre of mass shifts, it must maintain a new position to sustain an upright posture.

    This will benefit the biodiversity and fish stock populations, as well as megafauna, meiofauna and the fish diversity. Argument 1: Biotic Factors Biodiversity Biodiversity is the diversity or variety of ecosystems and natural habitats. In essence, it?s the variety of ways that species interact with each other and their environment (National Wildlife Federation).

    This development came at a time that human population was increasing and the ecosystem was feeling the pinch of this increased population. Man had therefore started adapting to his environment, which included eating some of the food, that they hade not known all their lives.
