The Correlation Between Egg Neglect And EDP

Improved Essays
Biologists see that species that have long adult lifespan, tend to be neglect about their offspring. The hypothesis is there is a positive relation between the time of egg neglect and the process of EDP. Not being attentive to offspring is rare in these two ark clades (the Aethiini and the Fraterculini) with the longest EDPs for egg weight. Sadly, the murres (Uria), whose eggs is always taken by predators when it is inattentive by adults. However, there is no correlation between egg neglect and EDP. According to the data, long lifespan is relate to the process of slow development. “In the Aethiini, the average adult survival rate is 87% in the diurnal least auklet (Aethia pusilla), and 86% in diurnal crested auklet (Aethia cristatella)”.

    Are we ready for an America made one quarter of genetically abnormal persons? Yet, this is how America will be, if fertilized eggs are given legal personhood. Fertilized eggs are single celled embryos which are incapable of survival on their own. Granting them legal personhood will be against the interests of humanity. It will invariably politicize the matter, interfere with research that can potentially revolutionize healthcare, deprive men and women of the right to choose the fate of their sex cells, and drive up healthcare costs on a logarithmic scale.…

    . Why does (or doesn’t) the frequency of a physical trait change in a rabbit population in different environments? c. This is an important investigation as understanding how populations are affected by different traits helps to understand why certain species thrive in an a certain an environment and why others don’t. This is an interesting investigation as there are no predators in this investigation, the rabbits are competing for food and that is why they are dying at an alarming rate.…

    It lays 1-3 eggs in it’s nest which is then sat on by the female most of the time until the eggs hatch. It has a better chance of reproducing higher in the mountains, especially when they choose to nest on a native tree called the Ohi. The breeding season is from March through September, and if a pair is together for one year they will most likely stay together for the rest of their life. They will keep their baby for about 7-9 weeks before they let them go. They are very territorial and can attack anything they feel that threatens them.…

    Darwinian Snails: Introduction The flat periwinkle is a small snail that lives on seaweeds growing on rocky shores in New England (McRae 2016). The scientific name of the periwinkle snail is Littorina obtusata. They were first introduced to the Atlantic Coast during the 19th century. These snails are known mainly for a morphological trait, the variation of shell thickness within the population.…

    Thermoregulation and reproduction are energetically costly events that many mammals face. To combat these obstacles, animals have developed the use of seasonally induced torpor and reproductive periods. Both of these events are usually initiated through a predictable environmental factor, primarily photoperiod. These two systems are usually mutually exclusive, but in Sminthopsis macroura, an Australian marsupial that reproduces in the winter, they can overlap since females with torpor being used during pregnancy. This study looked at the impact of reproductive hormones on torpor in the Sminthopsis macroura.…

    Axolotls have learned to adapt and change in order to survive in their habitat. They have learned to catch and consume prey, mate, breathe, and swim just to keep their species going. Axolotls are one of the most interesting and challenged creatures on earth. It is no wonder why they are endangered, and mostly surviving as pets in present day. Axolotls are born into a challenging and unique environment.…

    Wild Steelhead Essay

    Wild steelhead (O. mykiss) populations are in decline across much of their native range. Nevertheless, steelhead remain an important sport fishery and a key management species for state and federal agencies. Steelhead managers are faced with a number of challenges associated with regulations and recovery goals imposed by the Endangered Species Act (ESA), while simultaneously attempting to maintain recreational angling opportunities. Factors affecting recruitment and survival of wild steelhead include hydroelectric dams, land development (e.g., urban sprawl), first nation treaty rights, and modern agricultural practices such as irrigation canals and catchments. Understanding the dynamics of wild and hatchery steelhead populations is fundamental to implementing effective regulations and effectively focusing management efforts to improve and perpetuate the resource.…

    After much cajoling by the male, the female lays her eggs in the nest and the male takes over parental duties, guarding the fertilized eggs and fanning them with his fins to provide them with oxygen. This is essential to the survival of the eggs, without the male the eggs would parish and most like be eaten by other species. Because of climate change, many less males are born and less food is available to them when they're adults. Therefore, much of the eggs will die with the decrease of males being able to protect and nurture the nest.…

    The purpose of this experiment is to determine what causes the trends in the coloration in guppies. The data indicates that the trends in the coloration of the guppies is caused by the number of predators, the placement of the pool, the turbidity level, and that the coloration of guppies is sex-linked. The data shows that there are 5 brightly colored male guppies and 41 drab males in pool one, which is the closest to the main stream. Then in pool four, which is on the top of a waterfall, there are 108 brightly colored male guppies and there are 5 drab colored males. Also, in every single pool, there are no brightly colored female guppies, they are all drab.…

    Social behavior in desert tortoises is not well understood, though evidence suggests the presence of dominance hierarchies \citep{Niblick1994, Bulova1997} which may influence social structure and burrow choice in desert tortoises. In addition to social hierarchies, previous research suggests factors such as sex \citep{Harless2009}, age \citep{Wilson1999}, season \citep{Bulova1994}; and environmental conditions \citep{Duda1999, Franks2011} may influence burrow use in desert tortoises. If conspecific cues and environmental factors exhibit strong influence on burrow use, population stressors impacting these characteristics could alter typical burrow behavior. The two major population threats that have been identified in desert tortoise populations…

    Poeciliidae Evolution

    Comparative methods using maximum likelihood in phylogeny were constructed using RAxML 7.0.4, and different phylogenetic comparative methods were used to test for correlated evolutionary traits in Poeciliidae (Pollux et al., 2014). For one, the comparative method is applied to examine the potential conflict-driven shifts in sexual selection associated with the evolution of post-fertilization of maternal care in Poeciliidae fish family (Pollux et al., 2014). It is thought that maternal care intensifies after post-fertilization, which adds to fetal-maternal conflict (Pollux et al., 2014). This as a result causes a reduced reliance of pre-copulatory cues in males; display less developed, or the absence of, traits that facilitate female mate choice before copulation (Pollux et al., 2014). The matrotrophy index, which is the estimated dry mass of the offspring at birth divided by the dry mass of the egg at fertilization, is a measurement of post-fertilization maternal care (Pollux et al., 2014).…

    If you have ever baby sat or watched a younger sibling, chances are you’ve probably switched on the television, and watched the popular kid’s show Phineas and Ferb, which happens to have a very catchy theme song that is nice to hum to. But if you listen to the lyrics, there is a more sinister, sadder message behind the theme song. For instance, the theme song is about all of the possible adventures Phineas and Ferb can do during summer vacation, and most of them are strange and unheard of, such as finding a dodo bird, because they are extinct. It is sad because children will never actually be able to see a live dodo bird because their extinction was mostly anthropogenic and took place mid-1600s (bbc.com). Now in the 21st century, we, meaning…
