The first encounter with a live male blanket octopus, Tremoctopus violaceus Chiaie, 1830, illustrates the most extreme example of sexual size-dimorphism in a non-microscopic animal. Females attain sizes of up to 2 m long—almost 2 orders of magnitude larger than the 2.4-cm-long male. Weight ratios between the sexes are at least 10 000:1 and are likely to reach 40 000:1. Sexual selection and the ...

benign prostatic hyperplasia (bph) is a common disease in human that gradual overgrowth of the prostate gland leads to impinge on the urethra with impairment in urinary function. numerous plants improve uncontrolled growth of the prostate gland and improve urinary tract symptoms associated with bph. in this study, 25 healthy adult male wistar rats were divided randomly in five groups: g1 (contr...

objective: this study was aimed to examine the antinociceptive and anti-inflammatory effects of urtica dioica leaf extract in animal models. materials and methods: hydroalcoholic extract of the plant leaves was prepared by percolation method. male swiss mice (25-35 g) and male wistar rats (180-200 g) were randomly distributed in control, standard drug, and three experimental groups (n=6 in each...

conclusions acute administration of u. dioica impairs the object-recognition task if it is used only before the training session. this may be due to its modulation on the acquisition processing of object-recognition. u. dioica has no significant effects on the consolidation or retrieval processing stages of the nor task. these results emphasize the unfavorable effect on cognitive function of pr...

Male and female flowering plants of the dioecious Urtica dioica occur in approximately equal numbers in our study area on the coastal sand dunes of Meijendel. The seed sex ratio (SSR, fraction of males) collected from female plants in the field varied between 0.05 and 0.76, and differed significantly between maternal parents. After one generation of selection for either high or low SSR, female ...

Variation in food stoichiometry affects individual performance and population dynamics, but it is also likely that species with different life histories should differ in their sensitivity to food stoichiometry. To address this question, we investigated the ability of the three nettle-feeding butterflies (Aglais urticae, Polygonia c-album, and Aglais io) to respond adaptively to induced variatio...
