Density dependent limiting factors9/4/2023 ![]() ![]() Lying in wait: limiting factors on a low-density ungulate population and the latent traits that can facilitate escape from them. Density-dependent factors include disease, competition, and predation. Latent traits, such as overproduction of calves and migratory behavior, which do not currently enhance fitness, may persist within this population so that individuals with these traits can reap benefits when environmental conditions change. Density-dependent limiting factor - 14528317. It appears that predation on young calves, winter weather, and nutritional constraints may be interacting to limit this population. Productivity was significantly lower in the northern section of the study area where there is less high-quality habitat, suggesting that, even in this low-density population, nutrition could be a limiting factor. Find step-by-step Biology solutions and your answer to the following textbook question: Explain how density-independent limiting factors can affect. Approximately 60% of the calf crop died before 5 months of age. Density-dependent limiting factors lower birth rates or increase death/emigration rates via increased intraspecific competition at higher population. Density Dependent Limiting Factors Lack of rainfall Fires Competition between organisms for food Parasitism Predation Both of these factors do not depend on the size of a population of organisms which is why they are both independent limiting factors. Migratory status did not affect moose survivorship or productivity. Adult annual survival rates were high (∼89%), but may be negatively influenced by winter conditions. Climate temperature is not related to density-dependent factors affecting population growth because density-dependent factor is a limiting factor that. Generalized linear mixed-effects models were used to assess survival. ![]() We instrumented adult male and female moose with radiocollars and used aerial observations to track parturition and subsequent survival of juvenile moose. We evaluated survival of adult and juvenile moose ( Alces alces) in north-central Alaska to determine whether or not the population supported the hypothesis. The low-density equilibrium hypothesis predicts that in low-density opulations, predators regulate their prey and that the population will not escape unless predation pressure is eased. Predation, habitat, hunting, and environmental conditions have all been implicated as regulatory mechanisms in ungulate populations. All of the following are examples of density-dependent limiting factors except A.
