Chapter 29, Problem 2CT
All but one species of large birds native to New Zealand’s tropical forests are now extinct. Numbers of the one surviving species, the kereru (Hemiphaga, novae seelandine), are declining rapidly due to habitat loss, poaching, predation, and interspecies competition that wiped out the other native birds. The keruru is the only remaining dispersal agent for several native tress that produce big seeds and fruits, mainly because it is the only remaining species that can swallow big fruits (left) and expel big seeds whole. One of these trees, the puriri (Vitex lucens), is New Zealand’s most valued hardwood. Explain, in terms of natural selection, what would happen to puriri trees in New Zealand if the kereru becomes extinct.

Create a two-part figure showing the effects of forest fragmentation on the community of small mammals relevant to Lyme disease in eastern forests. Figure A should depict the interaction network of a large forestpatch with higher species diversity. Figure B should illustrate how the interaction network and transmission of Borrelia burgdorferi are different in a small forest fragment with low species diversity than they are in largeforest patches with greater diverisity. Eastern forests are diverse communities in which many species interact with one another. Your figure will be asimplified interaction network showing some of the most important species related to the ecology of Lyme disease. Remember that your goal is to illustrate how increasing fragmentation affects forest mammal communities in a way that increases Lyme disease risk.• Choose from the following species for your figure: black-legged tick, white-footed mouse, raccoon, eastern chipmunk, gray squirrel, white-tailed deer,…

- The large and heavy seeds of the limber pine (Pinus flexilis) lack the wings on seeds characteristic of most pines. The seeds are the primary food source for Clark’s nutcracker which harvests seeds after the cones open. It then caches thousands of seeds each summer and fall in locations far from the original tree to eat later in the year. During years when many cones and seeds are produced, the nutcracker caches 3-5x the number of seeds actually eaten. When they are present, tree squirrels remove the cone before it opens before the seeds are fully developed, and will eat the seeds immediately or cache the cone for later consumption. Question: Scientists were interested to see whether the two seed harvesters would affect seed and cone traits. They compared cone and seed traits in areas that had nutcrackers but tree squirrels were either present or absent. Where squirrels were present, cone mass was larger but there were fewer seeds per cone, and smaller kernels per seed.

Mathematical models based on random dispersal and reproduction have demonstrated that the speed with which such waves move is given by the expression 2Dr, where r is the reproductive rate of individuals and D is a parameter quantifying dispersal. Calculate the derivative of the wave speed with respect to the reproductive rate r and explain its meaning.arrow_forward

In its native SE Asia, annual and perennial populations can be found. Annual populations typically grow in aquatic habitats that dry out seasonally, while perennials typically grow in more permanent aquatic habitats.

An experiment was conducted where annual and perennial seeds were grown together in a permanent aquatic habitat and demographic data on survival and fecundity were collected.

They pose an added threat to many native bee species already at risk of declining numbers or even extinction due to increasing urbanization. A research conducted in Australia has very recently published in the Biological Journal of the Linnean Society. According to the study, a competition between the native bees and the introduced European honeybee is particularly intense in residential gardens dominated by non-native flowers (the native bees have co- evolved to forage on) and occurred when the bees shared the same flower preferences. European honeybees, being very abundant, and effective foragers, with the ability to exploit a wide range of flowers, can outcompete native bees for nectar and pollen resources. In this condition, what would you suggest rescuing the native bees as a biotechnologist? Justify your reasoning.arrow_forwardMutualism often involves co-evolution of mutualists.
