Fewer Rainy Days and Earlier Springs Linked in Northern Climates

Mar 30, 2022

By Pam Knox

A recent article from the National Science Foundation describes the result of a study on when new leaves appear on plants in spring by scientists at Ohio State University and published in Nature Climate Change. The study shows that while warmer temperatures are the primary cause of earlier leaf occurrence, the number of days of rain (not the amount of precipitation) also makes a difference, and as the number of rainy days per year has been decreasing in many areas north of 30 degrees latitude, this is also affecting how early the leaves come out. The researchers calculated that a decline in rainfall frequency will lead to spring arriving an additional one to two days earlier each decade through 2100. What would cause this? The researchers think that fewer rainy days means fewer cloudy days, too, and that more sunlight reaching the plants in spring stimulates them to produce leaves earlier in the year.

Video: Post-Weaning E. coli Control - Dr. Rodrigo Paiva

In this episode of The Swine it Podcast Show Canada, Dr. Rodrigo Paiva, DVM and PhD candidate at Iowa State University, explains how post weaning colibacillosis has changed in recent years and why pathogenic Escherichia coli has become more important in swine production. He discusses virulence factors, diagnosis, whole genome sequencing, biosecurity, and practical strategies to reduce disease risk while improving herd health. Listen now on all major platforms!

"Pathogenic E. coli now behaves like a robust, well-equipped truck carrying multiple tools for post-weaning disease."

Meet the guest: Dr. Rodrigo Paiva / rodrigo-paiva-09364355 is a veterinarian and PhD candidate at Iowa State University specializing in swine health, veterinary epidemiology, and post weaning colibacillosis. After several years working in commercial swine production in Brazil, his research has focused on understanding pathogenic Escherichia coli and improving disease prevention in modern production systems.
