Cosmopolitan species

mammal species were identified from all study sites (full list in Appendix 1). Swamp Wallaby, Bush rat, and Long-nosed Potoroo triggered most of the images containing terrestrial mammals. Swamp Wallaby, Short-beaked Echidna, Bush Rat and Eastern Grey Kangaroo were widespread over the study area. With the exception of Dusky Antechinus and Long-nosed Bandicoot, detection probabilities were high (0.80 – 0.99) (see Appendix 1 for details). The FD index calculations required at least three species…

water, enough oxygen for the masses, and with a viral pandemic plaguing humanity, it is not a farfetched vision. In our world today, “the walking dead” are not zombies on a mission to terrorize humans; the walking dead are millions of plants species, animal species, and ecosystems that are quite literally:…

of a community of species on the rocky shore of Te Raekaihou Point. The site data was collected from the rocky shore at Te Raekaihou Point, and my chosen species are the Blue-Banded-Periwinkle (Austrolittorina antipodum), and the Brown-Barnacles (Chamaesipho brunnea). The community pattern found in the rocky shore is zonation. Zonation is the division of plants and animals into distinct horizontal bands, or ‘zones’. The data collected shows zonation of the plant and animal species’, where the…

Describe how you would perform a random sampling to estimate the size of the population of your species you chose in the Galapagos. Use some actual numbers in your description. Try to base it on real numbers (this may take some research). What underlying assumptions must be made for this technique to be effective? [ /6 marks] Random sampling is a method used by biologists to estimate the size of a population by collecting data as each organism usually can’t be accounted for separately. By using…

In "First Flower" a group of botanists and paleobotanists reveal how that "abominable mystery" is starting to move towards a solution. NOVA captures images of how they are continuing to inspire new scientific discoveries today. It all begins in northern China, where amidst the country's rich, volcanic conditions for fossil-finding, Professor Sun Ge and his team first unearth the Archaefructus fossil from an ancient lake in a region where dinosaurs once roamed. Sun Ge brings his amazing find to…

of Gonodactylidac and others species which generally their prey on armored animal such as crabs, snails, bivalves and even their species. Size is not an issue to the smasher for example, Gonodactylids stun and crush hard-shield crabs equal to or larger than themselves (Caldwell, 1975). Capabilities of the smashers are also known to kill another member of their species with a single blow. The smasher actually are opposite of the spearers because the smasher species are mobile foragers for…

will differ in what can be suitable for the lizard. 2. There are six abiotic factors that influence where organisms live such as water, light, temperature, pH, salinity, and wind. These factors can affect biomes and the diversity of plant and animal species. Furthermore, water is a key factor in determining where organisms live because, it is essential for survival. For example, in biomes where the water supply is low, plants will be very short or small. Also, there will be a trend in low…

affect genes of a species, which can potentially eliminate animal spread diseases. A gene drive refers to a genetic system that manipulates a gene, guaranteeing all offspring to contain a certain dominant trait. As the trait is dominant it eventually spreads throughout the whole species, allowing them to all contain the manipulated trait. Scientists have designed this in order to eliminate mosquito-transmitted diseases such as malaria and Zika virus, but also to control species invasion. However…

organisms need each other to live. Without interdependence, the whole food web would collapse. Mutualism Mutualism is a symbiotic relationship that is beneficial to both species in the relationship. In some cases, both depend on each other, and need their relationship to survive. In others, both species benefit from the relationship, but do not need it to live. Many mutualistic relationships stand in the world, including multiple in the Chesapeake Bay and other estuaries.…

There are many reasons for collectors to want 20mm toy soldiers to 60mm toy soldiers. If they are building a miniature replica of a famous battle, they would want tiny, historically accurate soldiers for the battle field. Some collectors want to save toy soldiers because the soldiers can be admired and passed down to next generations. Ancient Roman Soldiers Toy Soldiers of San Diego has Ancient Roman Soldiers for those who want 2 1/2 inch tall Roman figures with accurate details. Each package…
