Morphological Abnormalities in Amphibians in Agricultural Habitats: A Case Study of the Common Frog Rana temporaria

From: Copeia | Date: December 20, 2006| Author: Merilà Pekkonen, Minna; ¤ , Juha; Piha, Henna | Copyright information

Recent studies suggest that the incidence of morphological abnormalities has increased in many amphibian populations, often exceeding the estimated background deformity frequency of 0-5%. Many chemical contaminants, including agrochemicals, can cause abnormalities in amphibians, but data on the occurrence of morphological abnormalities in wild amphibian populations in Europe is anecdotal at best. In a largescale study covering 264 ha and 26 farmland breeding populations of the Common frog (Ra...

Morphological Abnormalities of the Mid-Latency Auditory Evoked Responses in Schizophrenia
Clinical EEG and Neuroscience ; Introduction: Morphological abnormalities of the mid-latency auditory evoked responses (MLAERs, P50, N100, P200) have not been thoroughly examined as compared to latency and amplitude changes. Methods: An a priori defined set of morphological criteria was used to classify the morphology and latency
Genetic defects linked to body abnormalities in childhood cancer.(Brief article)
Community Practitioner ; Children with cancer have a higher prevalence of body abnormalities, such as asymmetric lower limbs and curvature of the spine, suggesting that the genetic defect responsible for the abnormality may play a role in the development of cancer, a study has concluded.

Colossal study shows amphibian woes.(Brief Article)
Science News ; For anyone who still doubts that amphibian populations are declining worldwide, Jeff E. Houlahan has a message: Give up. The ecologist at the University of Ottawa worked with an international team to crunch the biggest data set yet assembled for amphibian populations. The team collected information
The ups and downs of frogs.(teaching strategies)
Science Activities ; Scientists have been observing a worldwide decline in amphibian populations. Although some people question whether there is a global decline in amphibian populations or whether we are only witnessing natural fluctuations in populations, most scientists agree that something serious is happening.

Proceedings of the North Dakota Academy of Science ; Bacterial cell shape is defined by an exoskeleton-like structure composed of peptidoglycan (PG). Polymerization and maturation of PG requires certain enzymes called penicillin binding proteins (PBPs). One of these, PBP 3, is recruited to the cell division site by the scaffold-like protein, FtsZ, to
