What is the Puffinus sp. life cycle? 


Best insight from top research papers

The life cycle of Puffinus sp. involves annual migration between breeding islands and the north Pacific and Arctic Oceans. Breeding occurs in the warmer region, coinciding with the swarming of euphausian plankton. Gametogenesis begins in the northern hemisphere, and males possess bunched spermatozoa upon arrival at the breeding islands. Nest-burrows are renovated, and a pre-laying exodus occurs before fertilization takes place ashore. Incubation is shared between males and females, with alternating periods of fat deposition and utilization. Only one egg is laid per year, and breeding does not begin until the birds are six years old. Both parents feed the young but desert them while they are still in the burrows. Migration north occurs while abundant food remains, and the cessation of parental responsibility may stimulate contra-nuptial migration. The post-nuptial journey covers approximately 5,500 miles within about a month. The post-nuptial moult is divided into two phases, with the moult of wings and tail delayed until the sedentary phase in northern waters .

Describes the life cycle of Fusarium oxysporum f. sp. fragarie?7 answersThe life cycle of Fusarium oxysporum f. sp. fragariae, the pathogen responsible for Fusarium wilt in strawberries, is complex and involves several stages that enable it to survive and spread under various conditions. Initially, the pathogen resides in the soil or on infected plant debris, where it can remain dormant for extended periods until favorable conditions arise or a susceptible host is present. The pathogen infects the strawberry plant through the roots, exploiting wounds or natural openings to enter the vascular system, where it establishes and proliferates, leading to the blockage of water and nutrient transport within the plant. F. oxysporum f. sp. fragariae produces microconidia and macroconidia that play crucial roles in its reproduction and spread. Microconidia are primarily involved in the infection process, facilitating the colonization of new host plants, while macroconidia contribute to the pathogen's dispersal through water, soil, and possibly by human activities such as the movement of infected plants or soil. The pathogen can also spread through stolons from infected mother plants to daughter plants, a process that can occur without visible symptoms, making early detection challenging. Horizontal chromosome transfer (HCT) has been identified as a mechanism contributing to the pathogen's virulence and adaptability. This process allows F. oxysporum f. sp. fragariae to acquire genes that enhance its pathogenicity, enabling it to overcome host resistance mechanisms. The emergence of new races, such as race 2 in California, which can infect previously resistant strawberry cultivars, underscores the pathogen's ability to evolve and adapt to overcome genetic resistance in host plants. In summary, the life cycle of Fusarium oxysporum f. sp. fragariae involves soil or plant debris as a reservoir, infection through the roots, proliferation within the vascular system, and spread via conidia and stolons, with HCT playing a role in its evolution and adaptability.

What are the stages of the life cycle of Sitophilus granarius?5 answersThe life cycle of Sitophilus granarius consists of several stages. The eggs and larvae of S. granarius are unable to develop into adults following doses of gamma irradiation ranging from 30 to 500 Gy. Pupae, on the other hand, can develop into adults even after exposure to doses of 10 to 70 Gy. The immuno-osmophoretic technique has been used to detect the immature stages of S. granarius in wheat kernels, specifically larvae and pupae. In terms of protein fractions, the largest number of allergenic potential fractions was found in pupae, while the smallest amount was found in larvae. Carbohydrate, lipid, and protein levels were studied in the developmental stages of S. granarius, and it was found that the total amounts of carbohydrates and lipids increased with biomass growth up to the prepupal stage and then declined, while protein contents increased up to the prepupal stage, declined slightly in pupae, and increased again in adults.
What is the life cycle of a hookworm?3 answersThe life cycle of a hookworm involves several stages. The adult hookworms, which are about 1 cm long, reside in the small intestine of their host and feed on blood proteins. The eggs produced by the female hookworms are passed in the feces of the host. In optimal conditions, the eggs develop into rhabditiform larvae within 2-3 days. These larvae then molt twice and become infectious larvae. The infectious larvae climb up grass and form a cluster, known as a "larval tree". When a host comes into contact with the larvae, they penetrate the skin and migrate through the bloodstream to the lungs. From the lungs, they move up the trachea and are eventually swallowed, reaching the small intestine where they mature into adult worms. The larvae detect host components during their migration, initiating a signaling cascade that leads to their development and maturation.

How does genetic diversity contribute to the development of immunity in social insects?
5 answers
Genetic diversity plays a crucial role in shaping immunity in social insects. Studies on various species like termites and honey bees highlight different aspects of this relationship. While termites can enhance group diversity through colony merging, which may not necessarily improve immunity against pathogens, honey bees exhibit social immunity through behaviors like hygienic behavior, influenced by genes associated with neuronal development and sensory perception. In honey bees, genetic diversity resulting from the queen's mating numbers correlates with reduced disease intensity due to decreased variability in immune responses. However, in honey bees, the immune response does not seem to be directly influenced by genetic diversity, suggesting other mechanisms may underlie the positive effects of genetic diversity on pathogen resistance. Overall, genetic diversity in social insects appears to impact immunity through various mechanisms, including social behaviors and immune response variability.

Stimulatory effect of larvae presence on egg production of workers in ants?
5 answers
The presence of larvae in ant colonies can have a complex impact on the egg production of workers. Studies on various ant species like Cerapachys biroi, Aphaenogaster senilis, Pachycondyla villosa, Novomessor cockerelli, and Monomorium pharaonisreveal that larvae presence can influence worker behavior and egg production. In some cases, workers respond to larvae by increasing foraging activity and inhibiting ovarian activation, especially in smaller colonies. Workers may also regulate larval development, favoring worker caste over queen caste, and even engage in policing behaviors to control the development of larvae into queens. Additionally, the presence of larvae can negatively impact the number of worker-produced eggs, either through direct cannibalism or by affecting the rate of egg-laying when larvae are present. Larvae can also delay worker egg-laying, suggesting a regulatory mechanism for worker reproduction in ant colonies.
How many sexes are there?
5 answers
In nature, the number of sexes in organisms varies. While most diploid organisms have two sexes, such as male and female, some species exhibit multi-sex systems, with the frequency of sexual reproduction playing a crucial role in determining the number of sexes. Interestingly, certain organisms like ciliates and fungi have three or more sexes due to their unique mating mechanisms involving the exchange of genetic material. However, a constrained optimization model based on communication theory suggests that the two-sex reproduction scheme is optimal in nature, balancing reproductive diversity with the costs of time and energy for reproductive success. This highlights the diversity in sexual systems across different organisms, with the two-sex model being the most efficient solution in many cases.
