Digging in sand crabs: coordination of joints in individual legs.
Sand crabs use their multi-jointed legs to dig into sand. Combined movement and electromyogram (EMG) analyses showed that the pattern of intra-leg coordination in the legs of two sand crabs of different families (Blepharipoda occidentalis and Emerita analoga) is similar in legs 2 and 3, but very different in leg 4. For example, the sequence of proximal joint movements in legs 2 and 3 is elevati...
متن کاملNematodes Infect, But Do Not Manipulate Digging By, Sand Crabs, Lepidopa benedicti
We examined sand crabs (Lepidopa benedicti) for endoparasites, and found the only parasite consistently infecting the studied population were small nematodes. Because many nematodes have complex life cycles involving multiple hosts, often strongly manipulating their hosts, we hypothesized that nematodes alter the behavior of their sand crab hosts. We predicted that more heavily infected crabs w...
متن کاملFunctional autonomy of distant-acting human enhancers.
Many human genes are associated with dispersed arrays of transcriptional enhancers that regulate their expression in time and space. Studies in invertebrate model systems have suggested that these elements could function as discrete and independent regulatory units, but the in vivo combinatorial properties of vertebrate enhancers remain poorly understood. To explore the modularity and regulator...
متن کاملRadioiodine-treatment (RIT) of functional thyroidal autonomy.
Since 1942, therapy with radioiodine (RIT) has gained a major role in the treatment of benign thyroid disorders, notably hyperthyroidism caused by Graves' disease or toxic multinodular goitre (thyroid autonomy). In iodine deficient areas thyroid autonomy accounts for 40-50% of all cases with hyperthyroidism. RIT has become a cost-effective first-line procedure in autonomy-patients with latent o...
متن کاملSignificance of digging behavior to mortality of red imported fire ant workers, Solenopsis invicta, in fipronil-treated sand.
The effect of fipronil-treated sand on digging behavior and mortality of red imported fire ant, Solenopsis invicta Buren, workers was examined in the laboratory. No-choice digging bioassays where fipronil-treated sand was the only available digging substrate were conducted on two colonies at fipronil concentrations of 0.00, 0.05, 0.10, 0.50, 1.00, 1.50, and 2.00 ppm. Workers dug into the fipron...
