Climate change and loss of habitats are two big problems that affect how animals reproduce. These issues change many aspects of animal life, including their bodies, how they act, and how they adapt to their surroundings.
Breeding Seasons Change: When the weather gets warmer or wetter, it can change when animals breed. For example, a bird in Europe called the great tit starts breeding earlier because of warmer springs. Studies show that over the last 50 years, these birds have begun breeding about 9 days earlier than before because of rising temperatures.
Effects on Baby Development: Changes in temperature can also affect how embryos develop, especially in reptiles. Sea turtle eggs are very sensitive to temperature. They need to be kept at about 27 to 32 degrees Celsius to hatch properly. If the temperature goes above 29.5 degrees Celsius, most of the hatchlings will be female.
Food Shortages: Climate change can mess up food chains, making it hard for animals to find food when they need it most. For instance, North American birds like the red-winged blackbird depend on the timing of insect appearances to feed their chicks. If temperatures change and insects don’t appear when expected, many baby birds may not survive.
Worse Living Conditions: When people build cities or farms, it breaks up habitats for many animals. A study in the Midwest USA found that grassland birds, like the prairie chicken, have seen a 90% drop in their numbers because their homes were destroyed. This loss means fewer birds can breed successfully.
More Competition: When habitats are lost, animals compete for the limited food and space that’s left. In cities where native species live, they often have to compete with invasive species. This can disrupt how they breed and reduce the number of offspring.
Fewer Nesting Places: When habitats get broken up, there are fewer safe places for animals to nest, and they face more predators. For example, shorebirds like the piping plover have seen more of their eggs not hatch because their breeding areas are shrinking. Since the 1980s, their populations have dropped by more than 70%.
Overall, climate change and habitat loss seriously hurt how animals reproduce. Changes in breeding times, food shortages, more competition, and fewer safe nesting spots all contribute to this problem. To help protect our animals and nature, we need to create plans that address these issues and work to keep our ecosystems healthy and diverse.
