塔玛亚历山大藻对褶皱臂尾轮虫实验种群动态的影响

采用单个体培养方法研究有毒赤潮藻塔玛亚历山大藻（Alexandrium tamarense）的细胞再悬浮液、细胞破碎液及其与亚心形扁藻（Platymonas subcordiformis）的混合藻液对褶皱臂尾轮虫（Brachionus plicatilis）实验种群动态的影响．结果表明，塔玛亚历山大藻及其细胞破碎液延缓了褶皱臂尾轮虫的生长发育，使轮虫的生殖前期延长，生殖期及寿命缩短，特定年龄出生率降低，产卵量减少，从而导致轮虫生殖力下降，种群增长受阻．其中以塔玛亚历山大藻细胞再悬浮液对轮虫的影响最为显著，rm仅为0．1832d^-1，图1表2参18     

Ventilation rate and copulation in Octopus vulgaris

Typically three events occur when Octopus vulgaris Cuvier mates. The male inserts its hectocotylus into the mantle cavity of the female; the hectocotylus and the bodies of the male and female become quiescent; and the female increases its ventilation rate about 2.5 times, on the average, above its precopulatory base rate. It is hypothesized that the increased ventilation rate of the female provides the stimulus to the male to transfer its spermatophore to the oviduct. Since the insertion of the hectocotylus and the female's increased ventilation rate may be dissociated, it is suggested that copulation be defined as the attachment of the hectocotylus to the oviduct. A conditioned ventilation-rate increase in the female was observed with repeated testing. Observation of arching and pumping movements of the male as well as measurements of its ventilation rate before and during copulation indicate that only a few spermatophores are transferred per copulation.     

The feeding behavior of Beroe ovata

Patches of the neritic ctenophores Beroe ovata and Bolinopsis vitrea were observed on the edge of the Great Bahama Bank in order to determine the interaction between the predator Beroe ovata and its prey Bolinopsis vitrea. Laboratory experiments on Beroe ovata showed that it responds chemokinetically to the presence of its prey; as it swims it collides with other etenophores on which it preys. The unique use of macrocilia as cutting implements aids the predator in removing tissue from its prey, yielding maximum gain from each encounter. By means of direct observations while diving, data on horizontal and vertical patchiness, swimming speeds, abundance, and feeding behavior were collected, and used to assess the impact of populations of the predator on its prey. Together, these two animal populations form an ecological feed-back system which affects other portions of the planktonic community.     

Effect of arsenic species on the growth and arsenic accumulation in <Emphasis Type="Italic">Cucumis sativus</Emphasis>

The effects of arsenic (As) species, such as As(III), As(V) and dimethylarsinic acid (DMA), on the accumulation of As in cucumber (Cucumis sativus), as well as on its growth in a soil mesocosm were evaluated. When Cucumis sativus was cultivated in soils contaminated with 20 and 50 mg/kg of As(III), As(V) or DMA for 40 days, the growth was markedly inhibited by the inorganic As (As(III) and As(V)) rather than the organic As (DMA). Irrespective of the As species, the As concentrations accumulated in Cucumis sativus increased with increasing As concentration in the soil. The As bioaccumulation factors from soil into the tissue of Cucumis sativus were 17.5–35.4, 29.3–42.7 and 17.6–25.7 for As(III), As(V) and DMA, respectively. In addition, the As translocation factors from the roots to shoots were 0.025–0.031, 0.018–0.032 and 0.014–0.026 for As(III), As(V) and DMA, respectively. In conclusion, Cucumis sativus mainly accumulated As in its roots rather than its shoots and easily accumulated inorganic rather than organic As from the soil into its tissue.     

Temporal dynamics of Trichodesmium erythraeum (Cyanophyta) in the National Park "Sistema Arrecifal Veracruzano" in the Gulf of Mexico

Trichodesmium erythraeum Ehrenberg ex Gomont is a microalga worldwide distributed in tropical seas. This filamentous microalga was detected in phytoplankton samples collected in the Protected NaturalArea "Parque Nacional SistemaArrecifal Veracruzano", and because of its ecological importance, its temporal dynamics was studied using net samples (30 microm) collected in one year period. Samples were studied with a light microscope recording the presence, morphological characteristics, life form and relative abundance. Trichodesmium erythraeum occurred as single filaments and was rare in April 2007 and March 2008; as single filaments from May to August and December 2007; as single filaments and small aggregates in September 2007 and January 2008; in aggregates of large size (> 3mm) and high relative abundance in October 2007; and was absence in November 2007 and April 2008. Although the relative abundance of the species was not important comparing with other members of phytoplankton, its occurrence was frequent with a bloom at the beginning of the north winds period. The observed temporal dynamics of this microalga in this coral reef region comes up on the alert in the monitoring red tides programs being implemented in Veracruz coast.     

Permethrin induced oxidative stress and neurotoxicity on the freshwater beetle Laccophilus minutus

Biomonitoring has become a useful tool in environmental risk assessment of anthropogenic activities releasing disturbing pollutants. Permethrin, used worldwide to control a wide range of pest insects, can threaten aquatic biota, potentially useful as precocious bioindicators in ecotoxicology. This study seeks to assess the acute toxicity permethrin to the freshwater beetle, its availability in water, as well as, its uptake. The acute toxicity of permethrin to non-target species was studied under laboratory conditions to assess its effect, after the exposure 48 h, on the freshwater beetle Laccophilus minitus considering changes in some enzymatic activities; a specific biomarker of neurotoxicity (acetylcholinesterase) and a non-specific biomarker of oxidative stress (superoxide dismutase and catalase). The rates of permethrin in water and insects were determined using gas chromatography. The low measured concentration of the pesticide 0.0013 μg/L didńt modify the SOD and CAT activities in comparison with controls, only the high concentrations (0.023 and 0.18 μg/L) induced a significant increase in the enzyme activity. A similar profile was recorded for the H₂O₂ level. The permethrin treatment induced a drastic depletion of AChE activity. As outcomes, uptake at a low level (<6.8 ± 0.43 ng/g dry weight) showed to be the factor underlying the alterations in the beetles exposed to permethrin. Such findings provide information on the behaviour of permethrin within the environment and its biological target through its neurotoxicity and induction of oxidative stress in a freshwater beetle.     

Release of Cd immobilized by soil constituents and its bioavailability

Release of Cd immobilized by soil constituents (clay, humic acids, bacterial cells) in vitro and under soil conditions and its bioavailability to lettuce were studied. The most resistant to extraction with 0.02 M EDTA in vitro as well as under soil conditions was cadmium immobilized by humic acids during decomposition of contaminated plant residues but Cd‐dead cells when 0.1 M NaNO₃ was the extractant.

Cadmium addition (3 mg kg^‐1) to soil and its form were without effect on plant growth and amount of metal accumulated in roots. Tops of plants grown in soil supplemented with Cd‐resting cells contained significantly less metal then other ones.     

Hydroxyl radical generation and oxidative stress in Carassius auratus exposed to glyphosate and its formulation

Oxidative stress parameters and some antioxidant defense systems in the liver of Carassius auratus exposed to glyphosate and its formulation (Roundup®) have been studied. Fish were exposed to glyphosate and its formulation at concentrations of 0.032, 0.16, 0.8, and 4.0 mg L^?1, all calculated on glyphosate basis, for 11 days. Hydroxyl radical generation as determined by electron spin resonance spectroscopy of its spin-adduct with α-phenyl-t-butyl nitrone increased with the concentration of Roundup®. Superoxide dismutase activities were decreased relative to control by 21%–46% when exposed to glyphosate and 45%–52% when exposed to Roundup®, suggesting that the formulation is more toxic than glyphosate alone. Catalase showed no difference between both groups.     

Modulation of individual behavior and collective decision-making during aggregation site selection by the ant<Emphasis Type="Italic"> Messor barbarus</Emphasis>

Insect societies are often confronted with choices among several options such as food sources of different richness or potential nest sites with different qualities. The mechanisms by which a colony as a whole evaluates these situations and takes the appropriate decision are of crucial importance for its survival. Here we studied how collective decisions arise from individual behaviors when a group of workers of the ant Messor barbarus is given a choice between two aggregation sites. Two hundred ants were introduced into an arena and given a choice between two tubes connected to the arena. The tubes had different physical properties: dry and transparent (termed as dry), humid and transparent (termed as humid), or dry and dark (termed as dark). After 30 min, most ants were found to be aggregated in a humid tube when paired with a dry tube, or in a dark tube when paired with a humid one. When two humid tubes were in competition, ants aggregate more in one of the sites. The choice of ants was consistent throughout experiments. An analysis of individual behaviors shows that the probability of an ant recruiting and the intensity of its trail-laying behavior strongly depend on the quality of the tubes. Our study suggests that the selection of an aggregation site does not require that individual ants directly compare sites, but rather relies on the synergy between amplification processes involving recruitment by chemical trails, and a modulation of the individual resting time in a site as a function of its population.Communicated by L.

Development and application of cross-linked polyethylenimine for trace metal and metalloid removal from mining and industrial wastewaters

Pollution of water bodies by trace metals is an established problem and several studies have been conducted to deal with it. South Africa is amongst those countries whose water systems are most affected as a result of intensive mining activities. This research was dedicated to the development of an insoluble chelating polymer for use as an adsorbent for abstraction of metal ions from mining and industrial wastewaters. Polyethylenimine (PEI), well known for its metal chelating potential, was cross-linked by epichlorohydrin (ECH) in order to convert it into a water-insoluble form for direct use as an adsorbent. The binding affinity of the cross-linked polyethylenimine (CPEI) to heavy metal ions was assessed as well as its ability to be regenerated for re-use. CPEI exhibited good complexation ability to metal ions with high affinity to Cr and most divalent metal ions. The observed order of complexation was: Cr?>?Zn>?Fe?>?Ni?>?Mn?>?Pb. On the other hand, it showed very poor ability to bind oxo-anions such as SeO₃ ^2? and AsO₂ ^? which has been attributed to the unavailability of suitable functional groups to interact with these ions.
