What economic issues should be considered during conservation?

olchik [2.2K]

Answer:

Hybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations. Understanding the factors that contribute to destructive versus constructive outcomes of hybridization is key to managing conservation concerns. Here, we survey the literature for studies of hybridization and extinction to identify the ecological, evolutionary, and genetic factors that critically affect extinction risk through hybridization. We find that while extinction risk is highly situation dependent, genetic swamping is much more frequent than demographic swamping. In addition, human involvement is associated with increased risk and high reproductive isolation with reduced risk. Although climate change is predicted to increase the risk of hybridization‐induced extinction, we find little empirical support for this prediction. Similarly, theoretical and experimental studies imply that genetic rescue through hybridization may be equally or more probable than demographic swamping, but our literature survey failed to support this claim. We conclude that halting the introduction of hybridization‐prone exotics and restoring mature and diverse habitats that are resistant to hybrid establishment should be management priorities.

Answer the 1. Discuss briefly the causes, and consequences of climate change and how can we respond to the changing climate in t

BARSIC [14]

The causes of the climate change of Ethiopia are rapid deforestation, rapid population growth and agricultural expansions, air pollution etc. The consequences of climate change of Ethiopia are increase in the average temperature and the level of precipitation.

<h3>What is meant by climate change? </h3>

Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present. It results in the unexpected weather patterns and the change in the same making it quite unpredictable. It has been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.

<h3>What are the Causes of Climate Change? </h3>

More than 85 percent of emissions are due to agriculture and deforestation, while the power, transport, industrial and building sectors contribute 3 percent each. Globally, Ethiopia accounts for less than 0.1 percent of emissions, yet it is already experiencing the adverse effects of climate change. The major reasons or the causes of climate change in Ethiopia is rapid deforestation, rapid population growth and agricultural expansions, along with air pollution etc.

<h3>What are the Consequences of Climate Change?</h3>

Climate change is expected to increase heatwaves, droughts, flooding, and sea levels around the world, and also cause important health risks in Ethiopia. Ethiopia is vulnerable to many of the effects of climate change, including increases in average temperature and changes in precipitation.

<h3>Discuss in detail about the population characteristics of Ethiopia? </h3>

According to the 2022 revision of the World Population Prospects, the total population was 120,283,026 in 2021, compared to 18,434,000 in 1950. The proportion of children below the age of 15 in 2010 was 41.5%, 55.8% was between 15 and 65 years of age, while 3.3% was 65 years or older. The average age was 25.1.
