Georgia conservationists are putting hunters on high alert about the possibility of a deadly deer disease crossing the state border after the discovery of a case in north Florida.
The Georgia Wildlife Resources Division will carry out an emergency response once the state has its first detected case of Chronic Wasting Disease. It can take as long as two years before an infected white-tailed deer shows zombie-like symptoms of listlessness, droopy head, severe weight loss, repetitive walking and drooling.
In June, a road-killed doe found 38 miles from Georgia’s southwest border made Florida the 31st state to report a confirmed case of a condition that has no treatment or vaccine and always results in…

New research reveals how climate change can disrupt the evolutionary process and ecological balance. The study on apple maggot flies shows that warmer temperatures predicted for the future can affect these species differently, potentially halting speciation, and creating potential chaos in the ecological timing of insect communities.
New research delves into the potential repercussions of global warming on ecosystems, and how it could derail the development of newspecies.
Across the globe, new species constantly emerge as separate groups of organisms branch off and evolve in divergent paths. But what occurs when climate change becomes a variable in this complex equation?

Marine life booms with a spate of new species every 36 million years, and tectonic heaving is the indirect reason, new research has found.
A deep analysis of the fossil and geological record reveals a changing sea level that occurs in response to a 36-million-year cycle of tectonic movement.
This, a team led by geologist Slah Boulila of Sorbonne University in France has found, disrupts several ecosystems, causing many species to struggle – and new ones to blossom to fill the new ecological niches that emerge.
“In terms of tectonics, the 36-million-year cycle marks alterations between faster and slower seafloor spreading, leading to cyclical depth changes in ocean basins and in the tectonic transfer of water into the deep Earth,” says geoscientist Dietmar Müller of the University of Sydney.
“These in turn have led to fluctuations in the flooding and drying up of continents, with periods of extensive shallow seas fostering biodiversity.”
A close look at the fossil record shows that biodiversity is not a nice, even constant. Instead, it fluctuates dramatically on scales of tens of millions of years, punctuated by extinction events and the rise of new species.
What hasn’t been clear is what drives these changes; whether each event is unique unto itself, or whether there’s an underlying mechanism that links them.
The research by Boulila and team was a painstaking analysis of multiple geological datasets from the past 250 million years, combined with computational simulations and modeling using tectonic visualization software called GPlates.
Earth’s crust is never still. It consists of separate tectonic plates that are constantly moving and being recycled. Places where the tectonic plates meet beneath the ocean are known as subduction zones; there, water is sucked deep under the mantle, to be spewed out later via volcanic activity.
In their data and simulations, the researchers found a cycle of 36 million years in the diversity of marine life… and this coincided with a cycle found in tectonic, sea-level, and large-scale rock layer data over the same time period.
These findings, they say, constitute compelling evidence that the sea level changes triggered by Earth’s tectonic cycles play a key role in biodiversity cycles and shaping ecosystems.
“This research challenges previous ideas about why species have changed over long periods,” Müller says.
“The cycles are 36 million years long because of regular patterns in how tectonic plates are recycled into the convecting mantle, the mobile part of the deep Earth, similar to hot, thick soup in a pot, that moves slowly.”
There are other triggers throughout Earth’s history that can drive biodiversity. For example, the team also found evidence of a biodiversity cycle of 62 million years.
This could have been driven by changes in carbon dioxide levels, but it needs to be investigated further, the researchers say.
A manatee was found stranded on a beach in Volusia County, Florida, on Wednesday, July 5. Bodycam footage released by the Volusia County Sheriff’s Office shows the team effort by at least 12 volunteers to hoist the manatee off the sand.
VOLUSIA COUNTY, Fla. – A beached manatee in Florida is recovering after life-saving help from a large group of rescuers.
On Wednesday, deputies with the Volusia County Sheriff’s Office joined the Florida Fish and Wildlife Conservation Commission, Volusia County Beaches and members of the County of Volusia Marine Mammal Stranding Team to help carry the stranded manatee off the beach in Ponce Inlet.

The sheriff’s office released bodycam footage showing at least a dozen people using a stretcher to lift the manatee into a vehicle. Nearby beachgoers watched rescuers successfully transport the animal into a vehicle, where it was eventually taken to the Sea World Rehabilitation Center.
Authorities remind residents and visitors not to approach or touch a stranded animal. Instead, you should report them to the Florida Fish and Wildlife.

Marine mammal strandings are common along the Florida coast, according to the Volusia County Marine Mammal Stranding Team. It occurs when live animals beach themselves or dead animals wash up on the shore.
Many of the reasons why live animals beach themselves are unknown.
Florida manatees and bottlenose dolphins are the most common animals that are found stranded in Volusia County.
Adolphin and its calf have been rescued from the Louisiana pond they were trapped in for nearly two years.
The two animals were stuck in the pond system near Grand Isle in the Pelican State.
Audubon Coastal Wildlife Network (CWN) and partners in the Southeast Region Marine Mammal Stranding Network managed to rescue the stranded mammals on June 17, CWN said on a Facebook post.
The dolphins became stuck due to a storm surge and flooding caused by Hurricane Ida, which battered Louisiana in August 2021.
The CWN had been aware of the pair for some time, monitoring them for over a year.
The Grand Isle is a town on a narrow barrier island in the Gulf of Mexico. Although there are some species of dolphin that can survive in freshwater, these particular dolphins need saltwater in order to survive. Luckily, this pond system has enough salinity, as well as food supplies and tidal flow. This meant the dolphins were able to survive for the past two years.
However, there is not any pathway to the Gulf of Mexico, into their natural habitat.
The rescue team was made up of NOAA Fisheries Service in partnership with Audubon Coastal Wildlife Network (CWN), National Marine Mammal Foundation, SeaWorld Orlando, The Institute for Marine Mammal Studies, Dauphin Island Sea Lab, and South Carolina Aquarium.
A video of the rescue showed teams easing the dolphins onto a mat, floating within the pond.
Rescuers can then be seen transporting the dolphins in a boat towards the open ocean. They gently kept the dolphins wet using sponges.
Dolphins need to be kept wet at all times, or they run the risk of becoming dehydrated. Even though they cannot breathe underwater, they still need to be wet in order to live.
At the end of the video, rescuers can be seen releasing the dolphins into the wild.
It is not uncommon for wildlife to become displaced during a hurricane.
Storm surges happen when atmospheric pressure causes sea levels to rise during a severe storm.
Marine wildlife are often at the mercy of these surges when storms occur.
Marine mammals and sea turtles are at particular risk.
“It is common for storm surge and increased coastal flooding associated with hurricanes to cause marine mammals and sea turtles to strand on land or be washed into inland waterways where they are not typically observed, such as lakes, ponds, and canals,” the CWN said in a Facebook post. “Animals may be found in these areas for weeks to months following the hurricane, requiring rescue by trained and authorized responders to return them to their natural habitat.”

People across the globe observe July 11 asWorld Population Day– designated by the United Nations to focus attention on the urgency and importance of population issues, including their relations to the environment and human development.
Over the past 12 months, the world saw two significant population milestones. First, in November 2022, the global population officially hiteight billionpeople. Second, in April this year,India surpassed Chinato become the world’s most populous country, according to UN estimates.
Two new reports were recently published with information on additional sporadic avian influenza (bird flu) human cases and outbreaks in wild birds, poultry, and other animals such as cats.
On June 30, 2023, the European Centre for Disease Prevention and Control (ECDC) confirmed Poland’s Chief Veterinary Officer of Poland announced that about 20 samples from domestic cats from different cities have tested positive for A(H5N1) influenza virus.
The director of the National Veterinary Institute in Puławy, Poland, stated that “they have detected two mutations that indicate that the A(H5N1) virus is evolving to multiply more easily in mammals.”
The ECDC stated several uncertainties regarding the source of infection, the potential of feline-to-feline and feline-human transmission of the particular A(H5N1) influenza virus strain, and the severity of the disease.
Poland’s authorities advise pet cat owners to prevent contact of their cats with other animals or objects from outside the homes and enhance hygiene measures.
And the statement also mentions the need to isolate any suspected cases from other pets due to potential shedding from the gastrointestinal tract.
Furthermore, there are too many uncertainties at this stage to properly assess the risk to the general public. And no human cases have been reported related to this event in Poland.
Separately, the U.S. Centers for Disease Control and Prevention (CDC) published an updated Technical Report on June 30, 2023.
The CDC confirmed it is actively working on the domestic situation with current clade 2.3.4.4b HPAI A(H5N1) viruses associated with infections in wild birds and poultry outbreaks, including conducting surveillance among people with relevant exposures.
And we are preparing for the possibility that these HPAI A(H5N1) viruses gain the ability for increased transmissibility to people.
The CDC continued to say despite the panzootic nature of highly pathogenic avian influenza (HPAI) A(H5N1) viruses in wild birds and poultry, only a small number of sporadic human cases of A(H5N1) have been identified since 2022.
Nearly all reported human cases since 2022 were associated with recent poultry exposures, and no instances of mammal-to-human or human-to-human transmission of the HPAI A(H5N1) virus have been identified.

U.S. egg production numbers are on the rise, signaling a rebuild after bird flu decimated commercial flocks last year and sent prices skyrocketing.
A total of 9.37 billion eggs were produced in May, up 4% from last year, according to the U.S. Department of Agriculture. Egg production levels were down as much as 6% earlier this year, but started to show signs of improvement in April.
Highly pathogenic avian influenza, a contagious disease often fatal to birds, has affected 325 U.S. commercial poultry flocks over the past year, but only seven cases have been reported since March. No cases were reported in the past 30 days.

HPAI, often spread by migratory birds, affected more than 58 million commercial and wild birds in the past year, the country’s worst outbreak on record, according to USDA data. As cases spread, supplies tightened and prices soared, especially for eggs.
U.S. egg inventories were down 29% in December compared to the start of 2022. More than 43 million egg-laying hens died from disease or depopulation efforts last year. Wholesale egg prices surged 267% on increased holiday demand. They have since decreased as flocks are rebuilt and farmers adopt biosecurity measures as HPAI preventative.
After last year’s outbreak, Brian Earnest, lead economist, animal protein at CoBank, said he anticipated HPAI to be a year-round issue in 2023 with a lingering expectation that it would be back in full force, but “that does not seem to be the case.”
Instead, the rate of infection among domestic commercial poultry flocks has significantly weakened, according to USDA data. No U.S. cases have been reported among egg-laying birds since December.
“It appears that maybe commercial flocks are growing some immunity to it,” Earnest said.
CEDAR CITY — Utah Division of Wildlife Resources conservation officers are seeking the public’s help after a buck deer was recently illegally shot and killed in southern Utah.
DWR officers received a tip on June 16 from an individual who discovered the dead deer while fishing at the Kanab Creek area of the East Fork of the Sevier River in Kane County. Upon further investigation, officers discovered that the buck deer had been shot behind the left shoulder. Investigators believe a small caliber firearm was used.Officers believe the deer may have been shot south of where it was found, due to the high flow and fast moving water in the river at the time. Due to the lack of decomposition of the carcass, investigators estimate the deer had been shot within the previous week of it being found, sometime between June 10–16.
