Dr. Tchernov's findings support an evolutionary theory called the "naked coral hypothesis," explaining why corals are absent from the geologic record for millions of years and several species rebound when conditions improve.
Alpha-lipoic acid (ALA) has been shown to be protective against acute mercury poisoning in several mammalian species when it is given soon after exposure.
Both wt and pacCc colony growth resulted in an alkalinization of the PDA medium, as has been observed previously for several Trichoderma species, when secondary nitrogen is available [ 36, 47].
We completed laboratory assays to estimate the direct contact toxicity of these insecticides to several natural enemy species when applied at field rates (Table 2).
From a physiological point of view, GAs play a stimulatory role in fruit development, as shown by the ability to induce parthenocarpy in several species [ 34] when applied in post-bloom phase and/or early development.
Gas films on leaves have been observed in field situations for several terrestrial wetland species when submerged in lakes, ponds, river edges and rice fields on floodplains: rice (Setter et al. 1987); P. australis, cover of New Phytologist, Volume 177(4); Spartina anglica (Winkel et al. 2011); and own observations (A. Winkel, T. D. Colmer and O. Pedersen).
In 2003, researchers started to make sense out of this variation when they reported that several species make loud clicks when far from a target, but reduce the loudness of their clicks as they approach (Au and Benoit-Bird, 2003).
In several species so far studied, when the nestlings are about three-quarters grown, the parents begin a new cycle, building a new nest nearby and laying eggs.
The polymerase chain reaction (PCR) detection technique is useful for identification of small numbers of species; however, when several species need to be identified, the PCR matrix is difficult to handle.
