Meat Ant (Iridomyrmex purpureus)

Also known as the Meat-eater Ant or Gravel ant, the meat ant is a species of rainbow ant (Iridomyrmex spp.) that occurs throughout Australia. Like most ants meat ants live in large underground nests that number around 64,000 individuals. Despite what their common name might suggest meat ants are omnivorous scavengers and will forage diurnally for whatever they can manage. Their common name comes from the fact that they are commonly used to clean carcasses. Interestingly meat ants do not have dedicated soldier and worker casts, instead they exhibit age caste polyethism which means they take on different roles in the colony at different ages. Young ants typically care for eggs and older ants form foraging parties.

Spatangus purpureus

…is a species of spatangid heart urchin that occurs throughout the entire North Sea and is distributed from the North Cape to the Azores and the Mediterranean. S. purpureus typically inhabits bottoms with coarse sand or gravel. From there it spends its live burrowed, collecting detritus that calls near it.

March 1, 2015 - Green Wood-hoopoe or Red-billed Wood-hoopoe (Phoeniculus purpureus)

Requested by: taylorrbranham

These birds are found in parts of Mozambique, Zimbabwe, South Africa, Botswana, and Namibia. They are mostly insectivorous, occasionally also eating some small reptiles, fruits, seeds, and nectar. They are about 17 inches (44 cm) long including their tails and both sexes look similar. Nesting in tree hollows and other cavities, parents are assisted by several non-breeding helper birds. The helpers and the male bring food to the female while she incubates the eggs. Greater and Lesser Honeyguides are sometimes brood parasites of these birds, laying eggs in their nests to be raised by the wood-hoopoes.

Abstract:

Lablab purpureus is an important forage legume in smallholder crop-livestock systems of East and Central Africa. Seed yields of L. purpureus are generally low owing to limited phosphorus levels in most soils. Amendment of soil with phosphorus fertilizers is thus critical in enhancing lablab seed production. The objective of this study was to investigate the effect of varying levels of Phosphorus fertilizers on seed yields and the resulting net benefits associated with each level. The paper examines results from three studies conducted in Uganda (treatments: 0, 15, 30, 40, 60, 80 and 100 kgP205 ha-1), Sudan (treatments: 0, 94 and 188 kg SSP/ha) and Burundi (treatments: 0, 20, 40, 60 and 80 kgDAP/ha). Generally, amendment of soil with P enhanced seed yield by 27, 18.4 and 4% in Uganda, Burundi and Sudan respectively. The highest increments in seed yield of 40, 27 and 5.3% were obtained at 30 kgP2O5, 60 kgDAP and 188 kgSSP Uganda, Burundi and Sudan respectively. Results from dominance analysis indicated that treatments 80 and 100 kgha-1 were dominated and their net benefits were lower than that of the control. In Uganda, marginal analysis showed that the marginal rate of return (MRR) from 0 to 15 and 30 kgP2O5 was 500 and 700% respectively, while moving from 15 to 30 kgP2O5 resulted into a MRR of 274%. The study concluded that the rate of 30kg P205ha-1 was the most economically viable rate for seed production in Uganda.
