Decadal-scale pollen records link land use and plant diversity change across European lowlands over seven millennia
Abstract Understanding the long-term drivers of biodiversity change requires datasets that expand the timescale of ecological observations. Using lake sediments as natural archives, we reconstruct plant diversity change at high temporal resolution across the Swiss Plateau, a key region for European land use history.
Shocking foods with gluten surprise unsuspecting customers
Gluten can be hidden in the strangest places. Sennarey Garven found out gluten is actually hidden in the adhesive of envelopes. Photo by Eric Allan. Each day we interact and come in contact with things which are not safe for some people. Did you lick the seal on the last envelope you sent out? This isn’t safe for someone who is gluten-free. Other things like soy sauce and some shampoos have the same ingredients that pose a health hazard to others.
Impact of injuries on post-secondary athletes
Athletics come with a risk of injury and strain on the body. Alex Doerksen shows his bodily commitment to volleyball during a practice on Feb 11. Photo by Eric Allan. Eyes foggy, time shifts and spins, you don’t know where you are or what day it is. You look up and see your team on one knee with grimaces on their faces. Confusion floods your mind. Suddenly, you look beside you and see a volleyball trainer asking you how many fingers they’re holding up. It dawns on you, I have a concussion.
New futuristic videogame brings community together
Arc Radiers’ community success after the first month of its release. Infographic by Eric Allan. A new extraction shooter is dominating the new multi-player game category. After its release on Oct. 30 Arc Raiders has taken its studio, Embark, to a whole new level of recognition. According to polygon.com, this exciting video game has been nominated for one of six, best multi-player games of the year.
Kodiaks men’s volleyball looks to continue legacy
Tristan Iwanczuk(l) covers Ben Dyck(r) during a scrimmage in preparation for a game against Concordia Thunder earlier this semester. Photo by Eric Allan. The Lethbridge Polytechnic volleyball season has arrived with new challenges of new leaders and fresh faces. Kodiaks men’s volleyball is facing a growth hurdle with a young team. During the off- season, the Kodiaks attained six first-year athletes. Ben Dyck, third-year left side hitter, says being a younger team does come with added complexity.

Fast-slow traits predict competition network structure and its response to resources and enemies
INTRODUCTION Global changes are dramatically altering ecological communities (Brooker, 2006). These changes can occur through shifts in plant performance (Ahmad et al., 2010) and alterations in plant–plant interactions (Matías et al., 2018; van Dyke et al., 2022).
Towards mechanistic integration of the causes and consequences of biodiversity
Highlights Understanding the links between causes and consequences of biodiversity is key to achieving conservation of both biodiversity and its functions, yet previous studies have mostly studied them independently.

Diversity-functioning relationships across hierarchies of biological organization
Spatial selection effects Studies of BEF effects in heterogeneous landscapes have revealed landscape-scale patterns that underpin system-level functioning. For example, the productivity of diverse plant communities might, at the local scale, be dominated by a few species (a selection effect [SE], Box 1). These SE might be driven by different species in different communities found in a larger landscape, reflecting different environmental conditions.
Fast-slow traits predict competition network structure and its response to resources and enemies.
Abstract Plants interact in complex networks but how their structure depends on resources, natural enemies and species resource-use strategy remains poorly understood. Here, we quantified competition networks among 18 plants varying in fast-slow strategy, by testing how increased nutrient availability and reduced foliar pathogens affected intra- and inter-specific interactions.
Climate, host and geography shape insect and fungal communities of trees - Scientific Reports
|
Abstract Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries.

The supply of multiple ecosystem services requires biodiversity across spatial scales - Nature Ecology & Evolution
|
Abstract The impact of local biodiversity loss on ecosystem functioning is well established, but the role of larger-scale biodiversity dynamics in the delivery of ecosystem services remains poorly understood. Here we address this gap using a comprehensive dataset describing the supply of 16 cultural, regulating and provisioning ecosystem services in 150 European agricultural grassland plots, and detailed multi-scale data on land use and plant diversity.

Towards the development of general rules describing landscape heterogeneity‐multifunctionality relationships
1.Rapid growth of the world's human population has increased pressure on landscapes to deliver high levels of multiple ecosystem services, including food and fibre production, carbon storage, biodiversity conservation and recreation. However, we currently lack general principles describing how to achieve this landscape multifunctionality. 2.We combine theoretical simulations and empirical data on 14 ecosystem services measured across 150 grasslands in three German regions.
What It Looked Like To Eat At McDonald's In The 1950s, Before All The Food Was Gross
Yes, McDonald's is still great as a guilty pleasure or a quick meal. It has restaurants in 119 countries around the world, but here in America it is almost unanimously considered to be... well... pretty gross. Here we look all the way back to 1948, when McDonald's was a revolutionary new dining experience and there was no such thing as Fast Food. Think about that when you're waiting for your order.
These Images From The Hubble Space Telescope Are Not Only Breathtaking, They Solved Some Of Life's Greatest Mysteries
The Hubble Telescope expanded our understanding of the fact that the universe is expanding at an ever-increasing rate. It also has one heck of a camera. And to celebrate the 25th anniversary of Hubble's launch into low-earth orbit, TASCHEN has published Expanding Universe, an extraordinary new photography book of Hubble's most mesmerizing and mind-altering photography. These are some of the most important images ever taken so soak them up in all their extraterrestrial glory.
This Gun Heiress Built A Crazy Victorian Mansion Where She Could Talk To Ghosts
When it was first completed in 1884, the house of Sarah Winchester, heir to the Winchester rifle fortune, was one of the largest in the United States and a modern marvel. It was also insane, with stairs and doors leading to nowhere, windows opening onto walls and a seance room where Ms. Winchester would consult with spirits about what to build next. And some say it's haunted by the spirits of those killed by the Winchester rifle, as well as Winchester herself after her death in 1922.
16 Rare Photos Of Marilyn Monroe As You Haven't Seen Her Before
A private collection of rare photographs of starlet Marilyn Monroe were recently sold at Heritage Auctions in Dallas, Texas. Carefree shots of the often troubled model and actress, primarily taken by Bert Stern during his Last Sitting session in 1962 just weeks before her death, sold for a grand total of $137,519 and included a range of images—from early, wide-eyed shots of Norma Jeane in 1945 to raw, sensual photos that capture her beauty and sometimes her sadness.
