Wildlife awakening on the nature shores of the St-Lawrence River

In May every year, wildlife is born again in Eastern Canada as temperature rise and days last longer. A stunning array of migrating birds start to land in the broadleaf and mixed forests of Southern Ontario and Southern Quebec. Migrating species coming all the way from Central America follow a green path across USA only to reach the Great Lakes and continuing on along the shores of the St-Lawrence River. Some seen in this compilation are:

– Blue-Headed Vireo
– Golden-Crowned Kinglet
American Goldfinch
Black-Throated Blue Warbler
White-Breasted Nuthatch

Not Tested, Not Protected, Badly Paid: Ukraine’s Medics Speak Out

The Ukrainian government promised that all medical personnel would be tested for COVID-19 once every five days, but doctors have told RFE/RL that has not happened. Medics also said that there were shortages of protective gear and that government promises of increased pay have not been met.

And big health care problems are unfortunately not the only problems in Ukraine.

That’s what my mother always told us in our home, in terms of brutality and so on.”

Members of the Jewish community, including Ukrainian holocaust survivors and US state politicians, protested outside of the Ukrainian and Iranian embassies Sunday morning, to mark Holocaust Remembrance Day.

Assemblyman Dov Hikind, who has been a leading figure in the lobby for deporting former Nazi citizens, warned attendees about “Ukrainians who worked with the Nazis“, saying they were “worse than the Nazis.”

Ukrainian holocaust survivor and president of the Holocaust Survivors Charity, Vladimir Ripa, lit candles during a solemn prayer that was accompanied by rabbinical prayers, and spoke about his brother and parents who were victims of the holocaust.

Ukrainian Jewish groups warn of ‘open anti-semitism’ after police demand list of Jews in organised-crime probe

UKRAINIAN police have been accused of “open anti-semitism” after a high-ranking official demanded a list of all Jews in the western city of Kolomyya as part of investigations into organised crime.

The chilling request was made in February, according to a copy of the document posted on Twitter on Sunday by Ukrainian Jewish Committee director Eduard Dolinsky.

“Please provide us the following information regarding the Orthodox Jewish religious community of Kolomyya, namely: The organisation’s charter; list of members of the Jewish religious community, with indication of data, mobile phones and their places of residence,” the letter stated.

It was signed by Myhaylo Bank, a high-ranking official in Ukraine’s national police force with responsibility for organised crime, who did not explain why officers are interested in the city’s Jewish community.

Spokesman for the Ukrainian Jewish Committee Jacob Zalichker refused to supply the information requested by Mr Bank and said the community would only responded if presented with a court order.

“It’s a total disgrace and open anti-semitism,” Mr Dolinsky told the Jewish Telegraphic Agency.

“It’s especially dangerous when it comes from a law-enforcement agency that we have to fight the very thing it is perpetrating.”

The city of Kolomyya lies around 250 miles south-west of the Ukrainian capital Kiev and has a sizeable Jewish community.

The scourge of anti-semitism is on the rise in Ukraine. Shocking incidents and attacks on Jews led by far-right nationalist groups and politicians were revealed last year in a 23-page document published by the United Jewish Community of Ukraine.

It coincides with a rehabilitation of Nazis, including legislation making it a criminal offence to criticise World War II collaborator Stepan Bandera.

Earlier this year, Kiev city council announced a programme for a year of celebrations of the birthdays of individuals the Communist Party of Ukraine has described as “Nazi killers, thugs, executioners and anti-semites.”

This includes the centenary of the birth of Nazi collaborator and war criminal Vasyl Levkovych, who, as head of the Ukrainian auxiliary police in Dubno, organised anti-semitic pogroms and the murder of 5,000 Jews and thousands of Poles.

Also included in the celebrations is the 115th birthday of notorious anti-semite Ulas Samchuk, a member of the extremist Organisation of Ukrainian Nationalists, who described the murder of the Jews of Kiev, including thousands of children, as “a great day.”

Why Tyrannosaurus rex had long legs


This May 2019 video is called Was the T-Rex really as fierce as its legend says? | T Rex: An Evolutionary Journey.

From the University of Maryland in the USA:

T. rex was a champion walker, highly efficient at lower speeds

Research finds leg length gave giant predatory dinosaurs the advantage of efficiency, not speed as previously thought.

May 13, 2020

Long legs may make good runners, but they’re great for walking, too. Scientists have generally assumed that long-limbed dinosaurs evolved their leggy proportions for speed to catch prey and avoid predators.

But a new study by the University of Maryland’s Thomas Holtz and his colleagues suggests that long legs evolved among the biggest dinosaurs to help them conserve energy and go the distance as they ambled along searching for prey. The study was published in the journal PLOS ONE on May 13, 2020.

“The assumption tends to be that animals with adaptations for running, such as long legs, are adapted for a higher maximum speed, but this paper shows that there’s more to running than top speed,” said Thomas Holtz, principal lecturer in the UMD Department of Geology. “When you’re a bigger animal, those adaptations may also be for endurance and efficiency. It may be about being a marathoner rather than a sprinter.”

Holtz and his colleagues analyzed a variety of metrics like limb proportions, size ratio, body mass and gaits to estimate the top speeds of more than 70 species from a group of dinosaurs called theropods. Theropods ranged in size from less than a half-pound to more than nine tons. They included Tyrannosaurus rex and the many other two-legged predators that dominated the age of dinosaurs for 180 million years. Bipedalism and running speed have often been cited as major contributors to their success.

The study revealed a more nuanced story. According to the new analysis, longer legs were associated with higher top speeds in small and medium-sized dinosaurs, but that didn’t hold true for dinosaurs weighing over 2,200 pounds. Scientists have known that larger body size can limit speed, and the study showed that large dinosaur species with longer legs were no faster than their stubby-limbed brethren. But they moved more efficiently.

By calculating how much energy each dinosaur expended while moving at walking speeds, the researchers found that among the largest dinosaurs, those with longer legs needed less energy to cruise around.

“That’s actually a very beneficial savings, because predators tend to spend a great deal of their time foraging, searching for prey,” Holtz said. “If you are burning less fuel during the foraging part of the day, that’s an energy savings that dinosaurs with shorter leg forms didn’t get.”

These results highlight the often-overlooked impact of body proportions on running ability and the limiting effect of large body size on running speed. Clearly, there are different kinds of runners. This work should broaden the discussion about what it means to be adapted for running.
