Wildlife Vocalizations: Ana Yoko Meiga

Throughout my journey in biological sciences in Brazil, I have been fortunate to have many incredible mentors who have guided me with their time, patience and belief in my potential— sometimes they believed in me even more than I believed in myself. One piece of advice from a mentor has significantly helped to shape my actions and career trajectory.

After completing my undergraduate studies in biology, I was eager to pursue a master’s program focusing on mammal ecology. However, I faced a series of rejections from every program I applied to, leaving me disheartened. During this challenging period, I volunteered with a researcher studying jaguars (Panthera onca) using camera traps in Carlos Botelho State Park in the state of São Paulo in my hometown in Brazil. One afternoon, as we returned from the field, I told one of my mentors about my frustrations and disappointments.

She listened and then said: “It’s normal to be upset when you don’t achieve something important, but there’s a timeline for being upset. Be careful not to let yourself go beyond that limit.”

This advice motivated me to persist. Instead of feeling sorry for myself, I chose to intensify my dedication, sharpen my focus, and study more for the next round of applications. And it paid off.

This experience taught me the value of persistence. As a Brazilian biologist facing challenges in pursuing a scientific career, I have learned to embrace “good fear” and “good anxiety”—the kind that doesn’t paralyze but pushes you forward, driving you to achieve your goals.

I am currently a PhD candidate at the University of Florida and have had many opportunities to grow in my career. Learning the importance of persistence, even when not confident, has been the key to my success. The support and guidance from mentors, coupled with a persistent spirit, have been instrumental in my journey. The advice from my mentor to manage disappointment and persist has been invaluable.

Raptor collisions increase around the world

Throughout the world, raptors are colliding with obstacles like communication towers, wind turbines and power lines, among others. Researchers conducted a literature review published in the Journal of Raptor Research to find out how raptors are attracted to these structures for perches, nesting sites or hunting habitats. The scientists, who used lots of data from rehabilitation centers and veterinary clinics, found that collision incidents have increased since the 1900s with the increase of human development. Vehicles, wind turbines and windows appeared to be the most problematic, but these structures affected different raptor species in different ways. For example, owls blinded by headlights are more likely to collide with vehicles. Eagles and vultures are more likely to collide with wind turbines.

Wildlife Vocalizations: Hannah Leeper

Growing up in Minnesota, my family spent weekends camping, hunting and fishing. I always knew that I wanted to work with nature and wildlife, but I didn’t have a clear idea of how exactly I would get to do that. I knew I couldn’t make a living from just hunting and fishing, but I wanted those two activities incorporated into my career.

We were camping on one particularly nice fall weekend when we noticed beaver (Castor canadensis) damage along the shoreline of the lake and a huge beaver lodge not far from the fishing dock. My dad showed me how to set Conibear 330 beaver traps, and explained how destructive beavers can be to a lake, especially when they chew up the trees on the shoreline and contaminate the water.

Early the next morning, I hauled a five-gallon bucket filled with rebar, Conibear setting tongs and beaver lure along the shoreline to check the traps we set the night before. To my amazement, there was a beaver inside! I was shocked that our efforts paid off, and we were able to catch the culprit destroying the shoreline.

As I was dragging the heavy beavers out to show off our catch, it clicked that I don’t only have to hunt and fish to have a happy, successful career. Nuisance trapping, conservation and education about the balance of ecosystems are all tied together, and I wanted every aspect of that to become my career. Mostly, I loved being outdoors, and I didn’t want to give that up.

Looking back now, I’ve learned that all animals—even beavers—serve important roles in their ecosystems, and the balance of those ecosystems depends on having those animals around. Since that day when I had the realization that I wanted to work outdoors, I’ve grasped as many opportunities as I can, including more nuisance trapping, visiting bear dens, collaring deer fawns, banding Canada geese (Branta canadensis) and conducting vegetation surveys for lynx (Lynx canadensis). I took technician positions in six different states with seven different agencies.

Every experience has further solidified my career choice, as I am currently pursuing a master’s degree in wildlife science. I wish every young wildlife enthusiast finds their path and pursues their passion for natural resources.

Habitat management helps at-risk butterflies

For a number of at-risk butterflies in the United States, habitat management can play an important role in keeping them from going extinct. Looking at 114 populations of 31 butterfly species in the U.S., including species like the Oregon silverspot (Speyeria zerene hippolyta), Taylor’s checkerspot (Euphydryas editha taylori) and Karner blue (Lycaeides melissa samuelis) butterflies, researchers found that the butterfly populations are declining at a rate of about 8% a year, or a 50% decline in a decade. But they also found that habitat management can slow down or even reverse these declines. Climate change is one of the main reasons for butterfly declines, as it’s causing butterflies to shift the time of their seasonal activities. But habitat management stymied this effect. “The strongest signal we found is that in places where people are actively engaged with ways to manage the habitat, the butterflies are doing the best,” said Cheryl Schultz, a professor of conservation biology at Washington State University and an author of the study published in the Journal of Applied Ecology. “That to me is super exciting because that means that habitat management can make a difference, even in the face of stressors like climate change.”

AI could help reduce wildlife deaths caused by fencing

Researchers are turning to AI to help wildlife managers find remote fencing that impairs wildlife movement or causes wildlife deaths. Around 1 million kilometers of fencing, largely built to contain livestock, stretches across the western U.S. In recent years, efforts to remove or replace fencing have gained traction as species like elk (Cervus canadensis), deer and pronghorn (Antilocapra americana) are unable to cross them. The problem for many conservation organizations, though, is that the fences are hard to find. To better map the potential wildlife barriers, Wenjing Xu, a postdoctoral researcher at the Senchkenberg Biodiversity and Climate Research Center, and Zhongqi Miao, an applied research scientist with the Microsoft AI for Good Lab, trained a computer to pick out fences from aerial images taken in southwestern Wyoming. The team reported that the system was able to identify about 70% of fences when compared to on-the-ground data. The preliminary research demonstrates how wildlife managers can use this technology across more habitats in the future.

JWM: Borneo turtles do well when logging is done right

Sustainable logging may help boost a vulnerable freshwater turtle’s occupancy in parts of Malaysian Borneo.

“Despite the negative association with logging with the flat-shelled turtles, they seem to be doing quite well,” said Nick Tan, who recently received his PhD from the Leibniz Institute for the Analysis of Biodiversity Change at the Museum Koenig in Bonn, Germany.

The Deramakot Forest Reserve sits in the northeastern part of Malaysian Borneo. Foresters had heavily logged the area in the past, but in the 1980s, they used a more sustainable method called reduced impact logging. This method is stricter about harvest rates and pays attention to other factors, like the direction a tree will fall. It also requires reduced roads and trails to logging areas and a 30-meter buffer around waterways.

Past studies have shown how this logging practice improved habitat for mammals in Borneo, but researchers hadn’t yet looked at its effect on reptiles there.

Tan’s colleague Sami Asad with the Tomorrow University of Applied Science in Germany had collected field data on reptiles from March to July in 2019. He and an assistant walked transects along eight waterways in Deramakot, recording turtle sightings. Some areas they surveyed had been logged a year prior, while others hadn’t been disturbed for 20 years.

The team collected the most data on two species—the Malayan flat-shelled turtle (Notochelys platynota), considered vulnerable by the International Union for Conservation of Nature, and the Malayan soft-shelled turtle (Dogania subplana), which is more common.

Sustainable logging and freshwater turtles

In a study published recently in The Journal of Wildlife Management, Tan and his colleagues analyzed the data Asad collected to see how sustainable logging was affecting these species. The researchers hoped these findings could help them make further recommendations aimed at decreasing the ecological impacts of the practice.

The team ran occupancy models based on the field sightings of these nocturnal reptiles and took into account factors like the lunar phase, rainfall data taken from nearby weather stations, distance to nearby logging roads, forest canopy height and river size.

The results surprised the researchers—flat-shelled turtles were seen more in Deramakot than the usually more common soft-shelled species. The average occupancy for flat-shelled turtles was 80% compared to 50% for Malayan soft-shelled turtles.

Tan said that the fact that both species have occupancy rates higher than 50% is a good sign for the sustainability of this logging practice.

The analysis also revealed the importance of rainfall for flat-shelled turtle detection. They didn’t appear as much when it was raining—possibly as they lay eggs on sandy banks in drier periods.

The vulnerable species was also found more in larger rivers and in areas that were more than 1,000 meters from a logging road. The logging roads might be affecting the water quality, Tan said, by adding sediment to the rivers—Malayan flat-shelled turtles prefer clearer water.

Fewer Malayan soft-shelled turtles

The data wasn’t as robust for Malayan soft-shelled turtles in this area since the researchers didn’t see as many. But the research revealed a weak trend suggesting that the reptiles seem to appear most about a decade after an area has been sustainably logged. They aren’t found as much during the first 10 years, then they seem to appear a lot more in the 11th year. After that, the occurrence seems to drop again. Tan cautioned that this data wasn’t as reliable as the trends they found for flat-shelled turtles.

It also isn’t clear why this might be the case and why the researchers found flat-shelled turtles more than soft-shelled turtles. But Tan said that soft-shelled turtles tend to be more tolerant of humans and development—they are often found in urban areas or university campuses, for example.

Neither the lunar phase nor the canopy height seemed to show any trend on turtle occurrence for either species.

Tan said the take-home message from the research is that both species tend to respond well to sustainable logging practices. The data on vulnerable flat-shelled turtles shows how important it is to keep logging roads away from waterways—these should be carefully managed to reduce the impact.

It’s also important to check the weather before conducting surveys, he said. Their data revealed that rainy weather will likely result in fewer sightings.

In the future, he added that it would be good to compare turtle occupancy in these sustainably logged areas with forests that had been more heavily logged.
