nobody is ever cringe because i survived two ecohydrology field trips where i meowed loudly and with severe distress because the driver was SHIT and nobody seemed to really care ? so if i survived that and got an A+ i think you can do anything forever

Please tell me is there any ecological benefit to carp? I will stop hating carp if I can be convinced. I’m just bitter about carp. They’re huge and they don’t even taste good.

Not my first ask💀💀💀. Get off anonymous u coward. I must know who this is.

And I'm no expert, but a quick Google search shows that they're prized for by anglers. Also koi fish are technically carp, and they're awesome af.

As food they should be pretty tasty, maybe u just went to a bad carp place

Here's a peer reviewed article saying carp aren't all bad ecologically. https://www.sciencedirect.com/science/article/abs/pii/S1642359321000677

Basically more nutrients in the water, it's all around neutral. Don't believe the anticarp propaganda

musings of the unfortunately employed

now that im back from my 4 months of internship abroad (not fun) (long story) i have the whole month of august full of work ahead of me with only wednesdays off (is that even legal?)

and the dread of it all is just making me think like. what is it i do want to do. ive always worked in retail as i cant sustain myself on commissions (bad personal planning) and its difficult getting hired anywhere else. im currently studying ecology/ecohydrology but even that is starting to feel like something id hate to do 9 to 5, much like everything else. 16% of autistic adults are employed and now more than ever i understand why. im not made for this way of life, so what am i made for? by god, dude, what do i even want to do?

earlier today my partner suggested (jokingly) i start a crystal shop, since im always surrounding myself with the damn things, and like that i can be among them at all times. and like. fuck, i dont know, maybe? i would love nothing more than to have my own shop of little gems, trinkets, treasures and whatnot, selling online or from a physical store, but i dont even live on my own and neither does my partner. i could hardly fill our parents' houses with inventory for a business i might not even be successful in, let alone the investment it takes to even get those things ethically sourced. it was a pleasant but fleeting fantasy to indulge in and maybe something i can take with me when we move to live on our own.

but in the meantime??? when uni starts back up ill be working sundays, hating every minute of it, dreading the moment i have to get up for it in the morning as soon as its thursday and its all in sight again. i desperately want to do something else, even considering going back to filling my weekends with commissions again, but we all know how that went when i still lived in belgium (not good). anything remote would be a dream... but who even hires remote only on weekends? this will be my third year at the garden center and i know my coworkers well, so putting myself into something new almost doesnt seem worth it, but you know, can't help wishing it could be better.

perhaps after this last year of uni i can find a job that doesnt eat away at my will to live lol. a girl on tiktok was spreading the good word of data processing jobs that can possibly be remote so i may look into that being a thing where i live. or, if i make a solid plan for it this time, venture back into design work with the support of my partner....... or maybe ill pick up a career in jewelry making

for now, unfortunately, epic loss for autism coming 6 day workweeks

全学体験ゼミ「ダムと土砂と海」が実施されました Fieldwork "Dam, Sediment and Sea" was held.

2月25日に全学体験ゼミ「ダムと土砂と海」が開かれ、参加学生が生態水文学研究所の砂出しを体験しました。 On February 25, Fieldwork, "Dams, Sediment, and the Sea," was held, where participating students experienced sand removal at the Ecohydrology Research Institute.

最初に砂出しの説明を受けた後、水を抜いた量水堰内を測量してたまった砂の量を計算しました。 After an initial explanation of the sanding process, they surveyed the drained weir to calculate the amount of sand that had accumulated.

流れてくる水の力を利用して効率的に砂を出せるように、ジョレンや備中といった道具で流れをコントロールする必要があります。技術職員による指導の下、学生たちがひたすら砂を崩しました。 It is necessary to control the flow with tools such as jolens and bittyu so that the sand can be efficiently brought out by the force of the flowing water. Under the guidance of the technical staff, the students worked diligently to break up the sand.

砂出し作業開始直後の様子です。中央部に砂山があります。 This is a view of the sand removal operation just after it started. There is a sand pile in the center.

流れの邪魔になる落ち葉のかたまりやヘドロ層を崩し、砂を寄せて水流が砂山にあたって崩れるように調整していきます。 They break up clumps of fallen leaves and sludge layers that obstruct the flow, and then adjust the sand so that the water flow collapses against the sand pile.

最終的に砂山が完全になくなりました。皆さんお疲れさまでした。 Finally, the sand pile is completely gone. Thank you all for your hard work.

ECOLOGICAL IMPACTS OF ECOHYDROLOGICAL INTERVENTION ON THE WETLANDS ALONG THE SOUTHEASTERN SHORE OF LAKE TANA, ETHIOPIA |  Journal of Global Ecology and Environment

Wetlands in the Lake Tana watershed are important for nutrient and sediment retention, biodiversity, and hydrological processes. Although ecohydrological remedies have been presented, there has been little research on the effects of ecohydrology intervention on biological issues. Information on the ecological consequences of an ecohydrology-based intervention method in the wetland environment is critical for boosting biodiversity and improving water quality. The goal of this research was to see how ecohydrological intervention affected macrophytes, phytoplankton, and zooplankton in the wetlands around Lake Tana's coast. Along vegetation and water depth gradients, quantitative features of macrophytes and plankton sampling were undertaken using the transect and quadrat methods. Each fixed sample site has its biological data measured. Phytoplankton, macrophytes, and zooplankton across the sample sites were substantially different (p0.05). Low-disturbed wetlands have more macrophytes, phytoplankton, and zooplankton variety and quantity than moderately and severely disturbed wetlands. The study's overall findings revealed that biological abundance and diversity were linked to the degree of wetlands degradation. As a result, the variables that may contribute to the deterioration of wetland resources within and around the watershed should be prioritised. To protect and avoid future deterioration of wetlands near Lake Tana's coast, immediate ecohydrology-based intervention techniques should be employed.

the latest installment of “what’s he doing with his life this week?” is that i’ve discovered a way to integrate my interest in design and love of physics and coastal ecosystems —

i’m going to try to get my masters in civil and environmental engineering semi concurrently with my architecture masters (“architecture” lol this department is giving me a long leash) so i can do a joint thesis in the physical processes regulating salt marsh migration (sediment transport, fluid flows through vegetated areas, details pending tbh) as it pertains to coastal resilience, restoration, and adaptation of the built environment. and honestly if i can’t i’m going to think pretty seriously about dropping my arch masters all together.

i’m *very* excited because i’ve missed doing MATH frankly and all of my design proposals sound like science projects anyway (which my reviewers tend to point out lol whoops)

i LOVE LOVE LOVE coastal marshes and tidal zones i visit marshes on my weekend for fun.

and basically have been kind of disappointed with architecture and realize i would rather work as an early design environmental consultant than an architectural designer.

(we need more architecture that works with hard science and not just the aesthetic of science!!!)

so i’m meeting with a couple people in the coming weeks and also working on a proposal for a research grant for the NOAA and i’m !!!!!!

it’s finally starting to make sense what tf i’m actually doing in school lol

and the irony is ofc that i never thought i’d go to grad school for physics but realistically at this rate my phd work is going to be in fluid mechanics, ecohydrology, and coastal morphodynamics which is. basically physics of coastal waters. i ***may*** even get a chance to study/work in a WHOI lab which would be . a huge deal.

anyway i’m bubbling over w excitement so wanted to yell into the void

we can design nature-based interventions on our coastlines that increase ecosystem resilience while providing key services to *both* human and non human communities and i plan to be in the business of proving it!!!

published in the Journal of Ecology, scientists explain:    “This pattern has been explained with scale-dependent ecohydrological feedbacks and the reaction-diffusion, or Turing mechanism, used in process-based models that are rooted in physics and pattern-formation theory.”

Vegetation growth in Northern Hemisphere stunted by water constraints in warming climate

Vegetation growth in Northern Hemisphere stunted by water constraints in warming climate

A first-of-its-kind large-scale study of vegetation growth in the Northern Hemisphere over the past 30 years has found that vegetation is becoming increasingly water-limited as global temperatures increase.

The results are significant since vegetation is one of the biggest factors when it comes to controlling water and carbon cycling across Earth, which influences global temperatures. The work by IUPUI and Indiana University Bloomington researchers Wenzhe Jiao, , Qing Chang and Honglang Wang was published in the journal Nature Communications on June 18.

“Without water, living things struggle to survive, including plants,” said Lixin Wang, senior author of the study and an associate professor of earth sciences at the School of Science at IUPUI. His ecohydrology group led the study. “Changes in vegetation response to water availability can result in significant shifts of climate-carbon interaction.”

Honglang Wang is an assistant professor of statistics at the School of Science at IUPUI. Wenzhe Jiao, the first author, and Qing Chang are Ph.D. students at IUPUI and IU Bloomington, respectively.

This multidisciplinary research between the School of Science at IUPUI, the O’Neill School of Public and Environmental Affairs at IU Bloomington and two other universities began three years ago to determine vegetation constraints on a global scale. Until now, it was largely unknown, despite the growing interest in predicting global and regional trends in vegetation growth in response to climate change.

“Global temperature and the concentration of atmospheric CO2, or carbon dioxide, have been increasing,” Lixin Wang said. These changes are expected to cause increased atmospheric water demand, more frequent extreme hot days, and drought events. All these factors indicate that vegetation growth may have suffered more and more water stress under a warming climate.

“However, quantifying the changes in vegetation constraints at large spatial and temporal scales is challenging,” he said.

To overcome this obstacle, the researchers used satellite remote sensing data and meteorology data covering large spatial scales from 1982 to 2015.

“We developed our own metrics to indicate water constraints and then examined the changes in the metrics,” Jiao said. “The study is quite computationally extensive since we examined the relationship between vegetation growth and water deficit at each grid cell over the whole extratropical Northern Hemisphere — 604,800 data points each year — over more than 30 years.”

The data analysis provided strong evidence of a widespread, significant increase in water vegetation constraint in the Northern Hemisphere over the studied period. Some regions, like the Great Plains in the United States, were comparatively worse than others.

Until recently, elevated carbon in the atmosphere increased plant growth, which has the benefit of removing more carbon from the atmosphere. However, this study reveals a cause for concern.

“Increasing water constraints on vegetation productivity may drive a shift from a period of increasing land carbon sink strength to a period in which climate change is reducing land carbon sink strength,” Lixin Wang said.

In other words, the warming climate is increasing water constraints, reversing the earlier trend of stronger vegetation carbon uptake.

“Our research shows that increasing water constraints will likely limit continuous vegetation growth, thus slowing down the removal of CO2 from the atmosphere by plants,” Jiao said.

“The results emphasize the need for actions that could slow down CO2 emissions,” Lixin Wang said. “Without that, water constraints impacting plant growth — and the weakening of vegetation’s ability to removal of CO2 from the atmosphere — are unlikely to slow.”

As the world warms, a new study is helping scientists understand how cone-bearing trees like pines and junipers may respond to drought.

The research addresses a classic question in the field: When conditions are dry for long periods of time, do trees survive by growing new roots to tap water sources, or by relying on established roots that already go deep?

The answer, at least for some cone-bearing trees, known as conifers, may be the latter, says Scott Mackay, Ph.D., professor of geography in the University at Buffalo College of Arts and Sciences. Mackay is an expert in ecohydrology and how trees take up water.

In the new study, he led a team that used computational modeling to investigate how pines and junipers access water sources during prolonged dry spells.

In simulations, trees of both species survived a five-year drought when they entered the dry period with deep roots already reaching into fractured bedrock, where water can be found. These modeled trees also used water in ways that matched well with observations of real trees that successfully weathered drought conditions at the Los Alamos Survival-Mortality (SUMO) experiment site in New Mexico....

Hiya! My name is E Schwartz and I’m the one running this blog! This summer, I am participating in the Urban Water Innovation Network’s Undergraduate Research Program (UWIN-URP).

1.    What university do you attend and what is your major? Do you have any minors, concentrations, and/or clubs affiliated?

I attend the SUNY College of Environmental Science and Forestry (SUNY ESF) in Syracuse, New York. I’m earning my bachelor’s in Environmental Resources Engineering, with two corresponding minors in Mathematics and Water Resources. I am also the President of SUNY ESF’s Chapter of Engineers Without Borders, the Vice President of the Environmental Resources Engineering Club, and the Community Outreach Chair for the Student Environmental Education Coalition.

2.    Who are you project mentors and what are their affiliated universities?

My project mentors are Dr. Shirley Papuga and Dr. Kyotaek Hwang. Both are affiliated with Wayne State University in Detroit, Michigan.

3.    What are you currently researching? How does it relate to ecology, hydrology, and/or environmental justice?

This summer, I will be researching the connections between green infrastructure, urban water flow, and carbon dioxide concentrations. My project mainly focuses on using eddy covariance towers and image analysis to track the greenness of urban canopies. However, the whole lab’s study will illustrate whether or not green infrastructure has an impact on improving air quality and reducing environmental injustices. This research topic greatly shows the impact that cities have on climate change, resource sustainability, and socioeconomic status.  

4.    What has been your favorite piece of literature that you’ve reviewed for your research?

My favorite piece of literature that I’ve reviewed so far is entitled ‘Global Change and the Ecology of Cities,’ written by Nancy B. Grimm and others. This source did a phenomenal job of addressing the connections between environmental justice and ecohydrology, which allowed for me to further understand the severity of environmental racism. 

5.    What has been your favorite part of the UWIN-URP program to date?

The best part of the UWIN-URP program has been getting to know my fellow undergraduates within the program. Everyone is incredibly sincere and compassionate towards the environment – I truly feel like I’ve joined a phenomenal community.  

6.    What is the value you see in undergraduate research? What is one thing you would recommend to somebody starting research for the first time that you wish you had known?

One of the things I’ve loved about my undergraduate research opportunity is the amount of career options that have opened up for me. Prior to this summer, I had never considered graduate school or long-term research. Now, I’ve really enjoyed it and am looking into graduate schools! If you’re starting research for the first time, keep your mind and options open. Research is significantly more transdisciplinary that I had ever conceived, which allows me to pursue all of my interests in one context.

7.    What type of career are you hoping for after you graduate?

I’m still not quite sure, to be honest! I’ve considered enrolling with the Peace Corps because I’m quite passionate about humanitarian engineering. I’m also considering pursing a master’s and doctorate related to ecohydrology and ecological conservation, with the intentions of continuing research. There’s also the possibility of me going to law school, as I’ve always had an interest in the environmental legal system.

8.    What do you like to do for fun apart from your research?

When I’m not conducting my research, I love to listen to vinyl records or make Spotify playlists. I grew up playing four brass instruments and I still play two of them today – French horn and mellophone for Syracuse University’s Wind Ensemble and Marching Band, respectively. I also love watching adult animation and playing Dungeons and Dragons on rainy days, while hiking and petting dogs on sunny ones!

In forests, abundant trees are good and fire is bad, right? Actually, the reverse can be true — especially in some regions of California’s Sierra Nevada Mountains. That conclusion comes from a new study.

Trees don’t use all the water they absorb. They release some into the air through tiny pores in their leaves. The process is known as evapotranspiration. It’s a big word for how plants shed excess moisture as water vapor. Scientists can measure this released vapor. In forests, they sometimes put sensors on tall towers to get closer to the leaves.

Jim Roche works for the U.S. National Park Service in California at Yosemite (Yo-SEM-ih-tee) National Park. As a hydrologist, he measures the movement of water (in its many forms) on or near Earth’s surface. He is interested in how fires affect water in forests.

Roche and two of his colleagues worked in two river basins in California. A river basin is all the land that supplies water to a stream or river. The scientists compared how fires decreased greenery — a measure of forest cover — in the basins of the Kings and the American rivers from 1990 to 2008. They used satellite images to monitor greenery there from the skies. Next, they calculated water-vapor release in the past based on modern data. Then they compared the water-vapor release from burned and unburned patches of forest during each of the 18 study years.

Evapotranspiration is measured as a depth, in millimeters. That depth is how deep the released moisture — if it were all liquid water — would have covered an area of land. Fires that reduced green cover by 40 to 50 percent saved the forest some 153 to 218 millimeters (6 to 8.6 inches) of water per hectare (almost 2.5 acres) of land, the team found. In burned areas of the American River basin, that added up to roughly 77 billion liters (17 billion gallons) of water per year not being lost to the air.

Without people to suppress them, wildfires usually occur in parts of this forest every 20 years or so. If the entire 5,310 square kilometer (2,050 square mile) American River basin had been allowed to go through that natural cycle, the water savings per year increases to roughly 773 billion liters (170 billion gallons).

“It’s not a one-time gift — that’s every year,” Roche says. The team published its findings April 6 in Ecohydrology.
