Ants dominate vegetation stratum, exploiting resources like extrafloral nectaries (EFNs) and insect honeydew. These interactions are frequent in Brazilian cerrado and are well known, but few studies compare ant fauna and explored resources between plant species. We surveyed two cerrado plants without EFNs, Roupala montana (found on preserved environments of our study area) and Solanum lycocarpum (disturbed ones). Ants were collected and identified, and resources on each plant noted. Ant frequency and richness were higher on R. montana (67%; 35 spp) than S. lycocarpum (52%; 26), the occurrence of the common ant species varied between them, and similarity was low. Resources were explored mainly by Camponotus crassus and consisted of scale insects, aphids, and floral nectaries on R. -
Pathogens and Parasites of the Mussels Mytilus Galloprovincialis and Perna Canaliculus: Assessment of the Threats Faced by New Zealand Aquaculture
Pathogens and Parasites of the Mussels Mytilus galloprovincialis and Perna canaliculus: Assessment of the Threats Faced by New Zealand Aquaculture Cawthron Report No. 1334 December 2007 EXECUTIVE SUMMARY The literature on pathogens and parasites of the mytilid genera Mytilus and Perna was surveyed with particular focus on M. galloprovincialis and P. canaliculus. Likely pathological threats posed to New Zealand mussel aquaculture were identified and recommendations were discussed under the following topics. Epidemiological differences between New Zealand Mytilus and Perna There is a paucity of data for this comparison. Comparability or otherwise would inform predictions as to the threat posed by overseas Mytilus parasites to New Zealand Perna and vice versa. Samples of P. canaliculus and M. galloprovincialis should be surveyed to establish any significant difference in parasite loads or pathology. Invasive dynamics and possible development of pathological threat The greatest potential threat to New Zealand Perna canaliculus aquaculture appears to be posed by parasites introduced by invading Mytilus species. These common ship-borne fouling organisms are a likely source of overseas pathogens, the most important of which are probably Marteilia spp. and disseminated haemic neoplasia. Hybridisation of invasive and local mussels presents a further potential pathology hazard by production of a more susceptible reservoir host thus giving the potential for production of more infected hosts and greater water load of transmission stages. Such an increase in transmission stages might be a cause of concern for Perna canaliculus whose susceptibility is currently unknown. Studies on Marteilia and haemic neoplasia are required to address the following questions: Is Perna canaliculus susceptible to either of these pathogens? What are the current prevalences of these pathogens in local mytilids? What species of mussels are entering New Zealand waters? Do they include Mytilus spp. -

But I think I’d finally come down on the side of a parasite manipulating the behavior of its host – subverting it to the benefit of the parasite in ways that arouse admiration for the subtlety, and horror at the ruthlessness, in equal measure.

(Platyhelminthes: Trematoda) Infection in Frogs from Turkey. Introduction
69 Uludag Univ. J. Fac. Vet. Med. 27 (2008), 1-2: 69-71 First Report of Ribeiroia (Platyhelminthes: Trematoda) Infection in Frogs From Turkey. Şevki Z. CO ŞKUN * Mustafa N. MUZ ** Geli ş Tarihi: 25.02.2009 Kabul Tarihi: 09.03.2009 Abstract: Frog meat is one of the most desired dishes in some famous world restaurants. Turkey exports mil- lions of frogs collected from the nature in each year. Knowledge on the parasitic fauna of the frogs is very li- mited. The frogs (Rana ridibunda Pallas, 1771.) collected from central Anatolia (Ankara province and its vicini- ty) for exporting to EU countries were examined for tissue parasites. At inspection, yellow colored cystic structures with a diameter of 0.40 - 0.55 mm were observed among muscles. Number of the cysts in examined 33 frogs varied from 12 to 61. In the microscopic examination of the cysts, metacercariae of the genus Ribeiroia (Trematoda: Psilostomidae) were identified for the first time in Turkey. In North America, Ribeiroia is known to cause limb deformities in amphibians, and, since the infection has been included in the list of emerging diseases, these observations have evoked concern within the scientific and busi- ness communities. Key Words: Ribeiroia, Frog, Turkey.

The California red-legged frog is listed by the U.S. Fish and Wildlife Service as threatened under the Endangered Species Act. The California red-legged frog is particularly scarce in the Sierra Nevada with fewer than a dozen known populations. The building of ephemeral ponds a little over a mile from a robust California red-legged frog population which occurs on private lands will potentially allow expansion of the population from private lands onto public lands. The ephemeral nature of the pond will allow for California red-legged frog breeding without exposing the eggs and larvae to predatory fish and bullfrogs. These low-maintenance wetlands will also provide habitat for birds, bats, other amphibians, aquatic reptiles, aquatic insects, and drinking water for a variety of wildlife. Returning wetlands to the landscape would have other ecological benefits such as reducing erosion and improving water quality. The wetlands would be built so that most dry in the fall season. This way they would not support bullfrogs or fish, known predators/competitors of California red-legged frog.
