Feeding ecology of white perch Morone americana larvae, a major component of the ichthyoplankton community in the estuarine turbidity maximum (ETM) region of upper Chesapeake Bay, was evaluated in years of contrasting physical conditions. In 1998, high river flow led to an ETM with high turbidity and pronounced salinity stratification. In 1999, under low river flow conditions, turbidities in th...

Alpheopsis balaeniceps sp. nov. is described based on a single male specimen from Moorea, French Polynesia. The new species is unique within the genus Alpheopsis Coutière, 1896 in possessing balaeniceps-type setae on the fingers of both chelipeds, being especially well developed on the major chela. Within the family Alpheidae, this feature exists only in some species of the distantly related ge...

Copper (Cu) accumulation in shoot and root tissues and low molecular weight organic acids (LMWOA) root exudation have been studied in two metallophytes from Central Chile (Oenothera affinis and Imperata condensata) and two agricultural plants (Lupinus albus and Helianthus annus) growing under hydroponics conditions at increasing Cu levels (0, 0.125, 0.250, 0.5, 1 and 2 mg Cu/L). The plants were...

Three species of the processid shrimp genus Processa Leach, 1815, including two new species, are reported from shallow coastal waters in Okinawa Island, Ryukyu Islands, Japan: P. affinis Hayashi, 1975, P. filipes n. sp. and P. hayashii n. sp. The present specimens of P. affinis represent the rediscovery and range extension of this poorly known species, originally described from Indonesia. Male ...

Performing proteomic studies on non-model organisms with little or no genomic information is still difficult. However, many specific processes and biochemical pathways occur only in species that are poorly characterized at the genomic level. For example, many plants can reproduce both sexually and asexually, the first one allowing the generation of new genotypes and the latter their fixation. T...

BACKGROUND Oldenlandia affinis, commonly called 'kalata-kalata', a versatile plant used locally to treat malaria fever in some parts of sub-Saharan Africa was investigated for anti-plasmodial and anti-inflammatory activities. OBJECTIVE The study was designed to evaluate the antiplasmodial as well as anti-inflammatory activities of whole extract and cyclotide-rich fraction of Oldenlandia affin...

To explore the differences in the swimming ability and environmental adaptive abilities between male and female Gambusia affinis, we assessed the differences in burst swimming speeds (Uburst), critical swimming speeds (Ucrit) and their related fin areas, and consumption of energy substances after starvation at 0 (control group), 15, 30, 45, and 60 days, respectively. The results showed that the...

A laboratory experiment was performed to quantify the fate of diatom phytodetritus and how this is affected by the presence of benthic amphipods. A Baltic Sea spring bloom sedimentation event was simulated by adding 14C-labeled diatoms (Skeletonema costatum) to microcosms with varying densities of the amphipods Monoporeia affinis and Pontoporeia femorata, as well as to microcosms without amphip...

Chromosome numbers of one species Eranthemum (E. macrophyllum Wall. ex Nees) and five Strobilanthes [S. affinis (Griff.) Terao J. R. I. Wood et Benett., S. biocullata Y. F. Deng & Wood, dimorphotricha Hance, heteroclita D. Fang H. Lo pseudocollina K. He Qin] in the family Acanthaceae from China have been reported for first time. The chromosome were determined as 2n=4x=44 E. macrophyllum, 2n=2x=...

BACKGROUND The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. MATERIAL AND METHODS Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection a...
