Male monarch butterfly spermatophore mass and mating strategies

Male monarch butterflies, Danaus plexippus, produce a spermatophore which can represent approximately 10% of their body mass. Spermatophore mass increased with age in virgin males, and with the time since last mating in non-virgin males. Male monarchs did not delay re-mating until they were able to produce a large spermatophore. Recently mated males were as likely as virgins to copulate with bo...

Species-specific responses to landscape fragmentation: implications for management strategies

Habitat fragmentation affects the integrity of many species, but little is known about species-specific sensitivity to fragmentation. Here, we compared the genetic structure of four freshwater fish species differing in their body size (Leuciscus cephalus; Leuciscus leuciscus; Gobio gobio and Phoxinus phoxinus) between a fragmented and a continuous landscape. We tested if, overall, fragmentation...

Mating patterns and post-mating isolation in three cryptic species of the Engystomops petersi species complex

Determining the extent of reproductive isolation in cryptic species with dynamic geographic ranges can yield important insights into the processes that generate and maintain genetic divergence in the absence of severe geographic barriers. We studied mating patterns, propensity to hybridize in nature and subsequent fertilization rates, as well as survival and development of hybrid F1 offspring f...

Prioritizing and Identifying Strategies to Improve Tehran’s Transport Management in for the Post-Earthquake Crisis Situation

Background and Objectives: Recent earthquakes in Tehran showed that the fear arising from that, immediately caused traffic jam which the most important consequence is delay in relief. The purpose of the present study is to prioritize and identify strategies to improve Tehran's transport management for post-earthquake crisis situations. Method: This is an applied study which has done through de...

Loss of Chloroplast trnLUAA Intron in Two Species of Hedysarum (Fabaceae): Evolutionary Implications

Previous studies have indicated that in all land plants examined to date, the chloroplast gene trnLUAA isinterrupted by a single group I intron ranging from 250 to over 1400 bp. The parasitic Epifagus virginiana haslost, however, the entire gene. We report that the intron is missing from the chloroplast genome of twoarctic species of the legume genus Hedysarum (H. alpinum, H. ...
