Is your garden bee-friendly? – City gardens promote bee parasites

Parasites are threatening pollinator populations worldwide, raising concerns for the future of our food security. How we manage our gardens in cities could impact parasite transmission among pollinators, especially bees. Researchers found that bee parasites decrease when we plant plenty of flowers to promote diverse pollinators. We also reduce parasites when we refrain from mulching our gardens, as mulch covers nests for ground-nesting bees. As spring approaches, will your garden be friendlier to bees or their parasites?

For birds, drab is in fashion in our cities

Color has the power to affect our feelings and emotions. For many animals, color signals status or condition. Factors such as food quality, stress, and pollution can cause changes in animal coloration. The color of the background can also have significant effects on how animals perceive color. Cities introduce drab, grey buildings and pavement, pollutants, and reduced plant complexity. A recent study shows that city birds produce darker, duller feathers with less complex patterns.

From Food Waste to Roadways: Using Compost to Improve Soil Conditions and Tree Success Along Highways

Planting trees along highway roadsides is a good way to increase tree coverage in cities, but getting trees to grow here and maintaining these plantings over time can be difficult. Reducing soil compaction and adding organic material, such as compost, can improve roadside soils and support tree growth in these areas. A 5-year study in Ontario recently found that loosening up the soil and mixing in 10-25% food waste compost relative to soil can help improve tree growth along roadsides, possibly reducing the need to follow up and maintain these trees over time.

Life in the City – Humans alter city habitats for plants and animals

Cites are ecosystems, just like a forest, desert, and prairie are ecosystems. As human populations grow and move to urban areas, cities expand into other ecosystems. Plants and animals must adjust to the rapid changes that result. Humans are the biggest threat to organisms, but why are cities challenging environments for plants and animals? Let’s learn more about one of the largest and growing ecosystems on land… cities!

It’s Complicated: Plant-pollinator relationships differ from urban to rural areas

Flowers and the butterflies they attract are beautiful additions to any yard, but your garden is serving a greater purpose. Pollinators – including butterflies, moths, bees, and wasps – depend on plants for survival and are essential for plant reproduction. Plant-pollinator relationships are especially important for agriculture and our food supply. Cities pose many challenges for both plants and their pollinators which could strain their relationship. Find out how cities put pressure on plant-pollinator relationships and what you can do to help!

Begging birds: behavioral responses to human feeding in China

Bird feeding is a popular activity enjoyed around the globe. However, we don’t really understand how bird feeding can impact the behavior of birds. A new study from China took on this question by studying black-headed gulls. Read on to find out how food provisionings affected the behaviors of these birds
