More or less, compared to what? The general idea is that after a mass extinction there is less biological diversity than before it. It may take millions of years to recover the lost diversity once again.

What is the role of conservation to preserve the genetic diversity of plants and animals?

To avoid the bottleneck effect, where there's a "funneling" of the amount of genetic diversity available in a species. Less diversity means less plasticity and could mean less means to adapt and evolve.


What did nativism and decrease in unskilled jobs affect?

Nativism and a decrease in unskilled jobs will lead to less diversity. With less diversity and fewer jobs, fewer businesses will be willing to come to the area.


Stabilizing selection results in more or less genetic diversity?

Stabilizing selection typically results in less genetic diversity because it selects against extreme phenotypes, narrowing the range of traits present in a population. This leads to the preservation of intermediate phenotypes that are favored by the selective pressures, reducing overall genetic variation.


Is it better to make my own Diversity Training Videos, or buy a set that has already been made?

Making your own diversity training videos can be very expensive and you will most likely miss some points that diversity experts would not. A good set of diversity training videos can be had for less than $50.

What animals and plants became extinct during the Jurassic era?

First, please forgive me the correction, but the Jurassic was not an era, but a geologic period of the Mesozoic era.The Early Jurassic suffered a major extinction in the Triassic- Jurassic boundary.Many archosaur species went extinct, as well as most of amphibia (except small size specimen). In the sea, all conodonts disappeared from fossil register.Although dinosaurs, pterosaurs and ichthyosaurs were already present during the Triassic, this extintion gave the way to the reptilian gigantism of the Jurassic and the Cretaceous periods, along with bony fish gigantism, such as the largest know fish, the Leedsichthys.The Jurassic was not a very peaceful period; besides the above major extintion, there were, at least, two other less serious - but nevertheles significative - extintions.The supercontinent Pangea, the last supercontinent in the geologic history of our planet, began to broke apart, with intense vulcanism and earthquakes.Earthquakes, even with magnitude 9 or above in the Richter scale, were not as dangerous as today, because there were no buildings, and they could cause regional landslides or, in the worst scenario, non-global topographic alterations.So, during the Toarcian stage extintion, the sea fauna was hit more severely than the terrestrial fauna, with the total extintion of Ammonites, a long living cephalopod since the Devonian.The Tithonian extintion was less severe, but the Atlantic ocean was beeing formed with the tectonic plates mouvement and vulcanism, and the waters of the new ocean became anoxic, with the loss of marine biodversity.About the flora in the Jurassic, it was dominated by conifers and, in a less extend, the gymnosperms. So, about the flora, no severe extintion occured.Coralline algae, very important to coral reefs ecology, appeared for the first time.Ferns, of course, kept abundant but the advent of flowers had to wait for the Cretaceous...

Why is the value of a - 1 less than the value of a?

The - before the 1 represents it is less, so the -1 will always be less than a, since the - is before the one, and so that means the 1 is less than a.


What are the differences between sexual and asexual reproduction in terms of genetic diversity and offspring variation?

In sexual reproduction, offspring inherit genetic material from two parents, leading to greater genetic diversity and variation among offspring. In asexual reproduction, offspring are genetically identical to the parent, resulting in less genetic diversity and variation.
