Why did so much forest convert to dairy? - Whiteboard Friday. Endangered Species Foundation. Thought extinct since 1924, the ancient looking Canterbury knobbled weevil (Hadramphus tuberculatus) was rediscovered in 2004 by Laura Young, inhabiting golden speargrass in Burkes Pass, in the McKenzie country of South Canterbury.
This critically endangered weevil was once reasonably widespread in the Canterbury region (based on specimens collected over the last 120 years), but is now restricted to just one small localised grassland area of a few hectares. Whilst the spiky golden speargrass leaves are thought to provide this large weevil with some protection from introduced predators, the total population numbers less than 100 adults. Encouragingly recent attempts by Lincoln University researchers succeeded in captive rearing Canterbury knobbled weevils. Four adult weevils were introduced into a small enclosure in a glass house, which contained two species of Aciphylla speargrass plants (the preferred diet). ENT 425 – General Entomology. Insects, like all other arthropods, have an open circulatory system which differs in both structure and function from the closed circulatory system found in humans and other vertebrates.
In a closed system, blood is always contained within vessels (arteries, veins, capillaries, or the heart itself). In an open system, blood (usually called hemolymph) spends much of its time flowing freely within body cavities where it makes direct contact with all internal tissues and organs. The circulatory system is responsible for movement of nutrients, salts, hormones, and metabolic wastes throughout the insect’s body.
In addition, it plays several critical roles in defense: it seals off wounds through a clotting reaction, it encapsulates and destroys internal parasites or other invaders, and in some species, it produces (or sequesters) distasteful compounds that provide a degree of protection against predators. The hydraulic (liquid) properties of blood are important as well. Statistics. Number of deceased organ donors in New Zealand Please click below to download a printable PDF version.

Julius Caesar: Historical Background. 102/100 BCE: Gaius Julius Caesar was born (by Caesarean section according to an unlikely legend) of Aurelia and Gaius Julius Caesar, a praetor.
His family had noble, patrician roots, although they were neither rich nor influential in this period. His aunt Julia was the wife of Gaius Marius, leader of the Popular faction. c. 85 BCE: His father died, and a few years later he was betrothed and possibly married to a wealthy young woman, Cossutia. This betrothal/marriage was soon broken off, and at age 18 he married Cornelia, the daughter of a prominent member of the Popular faction; she later bore him his only legitimate child, a daughter, Julia. When the Optimate dictator, Sulla, was in power, he ordered Caesar to divorce her; when Caesar refused, Sulla proscribed him (listed him among those to be executed), and Caesar went into hiding.
North Taranaki - New Zealand Wars. North Taranaki War 1860-61 War broke out in North Taranaki in March 1860.
The issue over which the war commenced was a block of land, called the Pekapeka Block, now for the most part covered by the township of Waitara in North Taranaki. An Issue of Land In 1859, a local Te Atiawa chief, Te Teira offered to sell the Pekapeka Block to the Crown, an offer he had made on a number of earlier occasions.
Many other Maori objected to the sale. The Crown was caught in a bind; but not for long. An Issue of Authority This decision angered Te Atiawa, who were not about to allow the Crown to occupy the disputed Block. When an attempt was later made to survey the Block, Te Atiawa obstructed the surveyors and removed them from the area. Battle at Te Kohia The opening battle then was fought at Te Kohia, said by James Belich to be place where New Zealand’s great civil wars of the 1860s began. Further important engagements were fought at Puketekauere, Mahoetahi, No 3 Redoubt and Te Arei Pa.
Climate change on Tuvalu. The nine islands of Tuvalu are located in the middle of the Pacific.
Funafuti, the main island and capital, is at 1000 km North of Fiji. Tuvalu became, notably thanks to the climate conference in Copenhagen in 2009, the international symbol of the consequences of climate change. Sea-level rise, one of the most known consequences, is a major threat for Tuvalu, considering that this countrys highest point is 4,5 meters over sea-level (whereas most of the land is way below that point). The consequences of climate change will have and already have considerable impacts on these islands. In the National Adaptation Programme of Actions (NAPA), the government of Tuvalu has identified seven main and immediate threats for the livelihoods of Tuvaluans. Coastal: Following the Intergovernmental Panel on Climate Change, sea-level has already risen by 20 centimetres between 1870 and nowadays.
