Summary

 

Their findings suggest that the shrinking of body shape caused by global warming is a universal response to climate change, and revealed similar consistent and unexpected changes in body shape. They hypothesized that as the wing size decreased, the metabolic costs of flight increased, and increasing the wing length represented a compensatory adaptation to sustain migration. A better understanding of the morphological changes caused by climate change is important for predicting the response of living things to global change.

 

Evaluation

 

Over the past four decades, for 52 species of North American migratory birds, their size has decreased, while their wing lengths have increased. Although in our data the natural history, habitat and geographic distribution represented by this species vary, these changes are very consistent. As a result, global warming has changed migratory birds in some ways.

 

Reflection

 

As migratory birds shrink in size, they are less likely to survive, because larger and stronger birds will oppress them, leading to a reduction in their species.So global warming is sometimes not a direct cause of rapid extinction, and small changes can sometimes make animal species disappear faster.

Summary

 

Climate change and biological invasion are two of the world's major environmental challenges. Both may interact, for example, by changing the impact and distribution of invasive alien species. Although invasive species play a key role in damaging the health of bees, the impact of climate change on its severity remains unknown.

 

Evaluation

 

This is a clear case of global warming promoting biological invasion by pest species, and pests have the potential to seriously harm important pollinators worldwide. This has created a need for enhanced and adaptive mitigation and management.

 

Reflection

 

From a biological perspective, climate change has a great impact on living things. As a common insect, bees are often unable to cope with this particular pest, so the reduction in the number of species is also an inevitable trend.
