Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system?
Male stalk-eyed flies form leks where receptive females come visit
Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites.
Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime.
In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders.

In animals, the form of inter-sexual communication is often tied to the environment in which they live and operate. Describe how different forms of communication are linked to the environment in herptiles using three examples from three different taxonomic Orders.
With your knowledge of sexual selection theory, can you formulate a hypothesis that explains why female courtship might have evolved in this species? Is there anything about pipefish biology that might support your hypothesis?

What is the ecology of the grasshopper and how its external anatomy suits its habitat in which it lives?arrow_forwardHow is fecundation done in insects (external or internal)? Is there copulation between insects?arrow_forwardThe species Taenia saginata is a parasitic worm of humans. The parasite's life cycle is as follows: Hermaphroditic adults live in the small intestine cavity of an infected human. The adult worm consists of rings that are produced in the anterior region of the worm, in which there is production of male gametes which fertilize female gametes then these rings (called proglottids) detach from the posterior end of the worm and exit in the external environment through the anus of the infected human. The eggs resulting from fertilization, present in the proglottids, are released and can infect a bovid if they are ingested along with grass. In the bovid, the developing eggs are particularly localized in the muscles of the bovid and turn into a shape called a cysticercus (each egg becomes a cysticercus). 1-Specify which species is the definitive host of the parasitic worm, justifying your answer 2- Specify the type of parasitism of this worm, justifying your answer 3-Specify which is (are) the…arrow_forward
- In the greater ani (Crotophaga major) (Riehl 2011) and the acorn woodpecker (Melanerpes formicivorus) (Koenig et al. 1995), a group of females shares the same nest. However, when some females begin to lay eggs in the communal nest, their eggs are often tossed from the nest by other group members. Use a cost–benefit approach to explain why females whose eggs are destroyed still remain with the group. Do you think the egg-tossing females are really cooperating with the others in their group? Please Do not write from an online sourcearrow_forwardBecause the reproductive success of female Hanuman langurs (Semnopithecus entellus) is almost certainly lowered when a newly installed male kills their young infants, selection should favor countermeasures against infanticidal males. In this light, why might already pregnant females mate with a new male soon after a takeover even though they are not ovulating? What significance do you attach to the discovery that when mares are impregnated by stallions at stables away from their home locations, they will also copulate repeatedly with the males in their home stables upon their return?arrow_forwardThe Cnidarian life-cycle varies from species to species. The species obelia is characterized by exclusively dominant medusa stage exclusively dominant polyp stage alternation between an asexual polyp form and sexual medusa form alternation between an asexual medusa form and sexual polyp formarrow_forward
- Many factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care. [Select] [Select] protogynous hermaphrodite continuous hermaphrodite protoandrous hermaphroditearrow_forwardPlease explain migration and sexual navigation of Asian elephantsarrow_forwardExplain in detail why you would not expect to find a monozygotic twin when studying the offspring of scorpions, knowing that scorpions are protostomes belonging to the phylum Arthropoda.arrow_forward
