Ecosystem processes related to wood decay

Wood decay elements include snags, down wood, root wads, tree stumps, litter, duff, broomed or diseased branches, and partially dead trees, all of which contribute to ecological processes and biodiversity of the forest ecosystem. Down wood can serve as reservoirs for moisture and mycorrhizal fungi beneficial to the health and growth of commercial tree species. Decaying wood, leaf litter, small twigs, and roots contribute nutrients and structure to humus and soil organic matter, and host microbes that play beneficial roles in nitrogen cycles and other processes. Snags and down wood provide nurse functions for tree and shrub species, and can aid in restoration of degraded forest environments. Various elements of wood decay provide habitat for many species of wildlife including invertebrates, amphibians, reptiles, birds, and mammals. Fire can influence the amounts and distributions of wood decay elements and enhance or detract desired ecosystem processes, depending on severity, charring, soil temperature, and other factors. Managing wood decay elements for ecosystem processes entails better understanding decay dynamics, the role of coarse wood in soil, the role of wood decay in carbon cycling and sequestration, and other considerations.

Rangeland exclosures of northeastern Oregon: stories they tell (1936-2004)

Rangeland exclosures installed primarily in the 1960s, but with some from the 1940s, were resampled for changes in plant community structure and composition periodically from 1977 to 2004 on the Malheur, Umatilla, and Wallowa-Whitman National Forests in northeastern Oregon. They allow one to compare vegetation with all-ungulate exclusion (known historically as game exclosures), all-livestock exclusion (known historically as stock exclosures), and with no exclusion (known as open areas). Thirteen upland rangeland exclosures in northeastern Oregon were selected and are presented with plant community trend data and possible causes of changes over time. Key findings are that moderate grazing by native ungulates afforded by the livestock exclosures generally stimulated bunchgrasses to retain dominance and vitality; native bunchgrasses can replace invasive rhizomatous plants given a reduction in disturbance over time; shrubs increased without ungulate use in shrubland communities; and invasive annuals that established following severe disturbances to the grassland community diminished with aggressive competition from perennial bunchgrasses.

Relations of native and exotic species 5 years after clearcutting with and without herbicide and logging debris treatments

To increase timber production and manage other forest resource values, some land managers have undertaken logging debris and vegetation control treatments after forest harvest. We explored the roles of clearcutting on plant community composition and structure at three sites where logging debris was dispersed, piled, or removed and vegetation was annually treated or not treated with herbicides for 5 years. Without vegetation control, a competitive relation was identified between exotic and native ruderal (i.e., disturbance-associated) species. When exotic ruderal cover changed by 4 percent, native ruderal cover changed by 10 percent in the opposite direction. This relation was independent of site, but site was important in determining the overall dominance of ruderals. Five annual vegetation control treatments increased Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growth, but decreased richness and cover of other species at the rate of one species per 10 percent reduction in cover. Debris treatment effects were small and found on only one site.

The impending release of WordPress 3.6 has been pushed back one more week to April 29. At this time, WordPress 3.6 is not yet feature complete (meaning that all intended new features have not been entirely finished), so the decision was made to push the first beta release back two weeks to March 27 and the final release back one week to April 29. This will allow the team time to focus on finalizing the in-progress new features so that they (and the brave folks who enjoy running beta software) can simply focus on testing and bug fixing rather than polishing up partial features.

Many anticipated arts, cultural events delayed or canceled

Summer is going to look a bit different in the Corridor this year as many, long-cherished events are being canceled or postponed. And the organizations that run those events want you to know they aren’t any more happy about it than you are.

The organizers of these events are having to make unprecedented, tough decisions.

“Cancellation is not a good word in our business,” said Chuck Swanson, Building a Legacy executive director of Hancher. “It is something that we really don’t want to do and it takes a lot for us to come to that.

“We live for the live performance and bringing the artists and audiences together. That’s the happiest time for me, so none of these decisions have been easy.”

Hancher has had to cancel numerous upcoming events in the past few months that would have brought to Iowa City in artists from all over the country and the world. It also is holding off announcing its upcoming season — which it typically would be doing at this time of year.

this isn’t something the staff has faced since the floods of 2008 and because they book events so far in advance they are confronting additional challenges.

“You know there’s so much that goes into a show before it happens,” Swanson said. “I just think of all the anticipation, booking the artists, advancing the show, setting ticket prices, advertising and then ticket sales.

“It’s like a farmer who does all this work to get his crops ready and then at the end of the season ends up with nothing to harvest.”

He noted Hancher has been reaching out to its booked performers and, in some cases, have had performers reach out to them to cancel upcoming shows.

The significant time and resources that go into planning large-scale events is the main factor in necessitating cancellation discussions and decisions at many organizations.

“Many logistical items have to be coordinated, from renting shuttles to scheduling volunteers and staff. Initial planning for some events begins as early as 12 to 18 months in advance and proceeds all the way up to the day of the event,” said John Myers, Indian Creek Nature Center executive director.

Citing the center’s annual Maple Syrup Festival, he noted food represents a significant cost and often cannot be saved or reused.

“We have had to be mindful of the financial resources available to us and ensure that we wisely manage those to ensure (the center) can emerge from this pandemic as a functioning and healthy organization,” he said.

“None of the decisions to cancel events or how to handle subsequent financial losses are easy and they challenge everyone,” Myers added. “As our whole lives have been upended, it makes even the simplest of decisions harder and that takes an impact on morale.”

He acknowledged staff members aren’t the only ones feeling the strain.

“We have a significant core of volunteers who are no longer able to give their time, which also creates a strain on morale and increases the amount of work that needs to be done when we return,” he pointed out.

Another primary factor is what is allowed and considered safe by the city, state and Iowa Department of Public Health.

“At this point, only allowing groups of 10 or less is a far cry from the thousands or people we usually see at the Iowa Arts Festival,” said Lisa Barnes, executive director of Summer of the Arts in Iowa City, which produces the Iowa Arts Festival.

“The governor has announced that reopening the state will be done in stages, and based on what we’ve found from other events around the country, concerts and large festivals will be the last to open,” he noted.

Summer of the Arts announced just last week that the Iowa Arts Festival would not take place this year, a month in advance of the event.

“We needed to make a decision so that we can move forward with alternative plans,” Barnes said, noting the organization has had questions about the Iowa City Jazz Festival, scheduled for July 3 through 5 and added a decision regarding that festival and July programming will be made by mid-late May.

“We also needed to make the decision far enough out to be able to work with our performers and cancel the agreements,” she said.

On Wednesday, Gov. Kim Reynolds loosened some but not all of the social-distancing restrictions for the remaining 22 counties she had put in place.

Heartbroken

Discussions about the future of these events have been happening for weeks for many organizations, highlighting they are not taken lightly.

Carissa Johnson, executive director of the Cedar Rapids Freedom Festival, said conversations about the future of this year’s event started in mid-March, right around the time the Cedar Rapids SaPaDaPaSo Parade announced its cancellation for 2020.

“We plan year ’round for the two- to three-week festival,” Johnson explained.

“Our planning really ramps up in April and May, and we have many more costs associated with producing the festival the closer we get to the start. In order to protect our time and resources, we elected to cancel before we had more costs and variables to consider.”

As for who is making the final decision, organizations said many stakeholders are involved. Barnes said the decision on the Iowa City Arts Festival, for example, included staff, the board of directors, festival planning committees, the city of Iowa City and Johnson County Public Health, along with input from some of the vendors, artists and performers.

Tapping into experts in those public health field has been key as well.

“We have these assets, people, at the University (of Iowa), that have been really helpful as we make these decisions about canceling and as we prepare to think about reopening,” Hancher’s Swanson said.

The Freedom Festival include staff and board members in discussions, with recommendations from Linn County Public Health and the city of Cedar Rapids, factoring in the health, safety and well-being of the community.

“We are just as heartbroken as the rest of the community, but this decision was to protect our community as much as possible,” Swanson said.

“This community is a family and we will all get through this together and come back stronger next year.”

Myers noted organizations such as the Indian Creek Nature Center are also rely on advice from national associations, such as the American Alliance of Museums, and discussions among the leadership of many local cultural groups.

“For many events, we have also reached out to participants to gather their input and comfort level of attending once we are able to reopen,” Myers said.

The financial effects of having to cancel is stressful for organizations, too.

“Financially, this has been a hard time for the Nature Center to endure,” Myers pointed out. “We’ve had over 100 different programs, events and facility rentals canceled between March 15 and April 30, and our losses are currently over $250,000. As we approach the summer, there are a number of other events we continue to review, including our popular summer camps.”

The Nature Center has postponed a national conference to be held there in September — due to indications of low participation — for peers from around the nation who run not-for-profit and government nature centers.

“We are losing thousands of dollars in vendor fees and sales receipts because we had to cancel,” said Barnes, of Summer of the Arts.

“We have sponsors tied to certain events, like the Iowa Arts Festival, that in some cases want to carry over their support to next year, which impacts our fundraising for this year and next.”

She noted her group already has been made aware of funding that won’t be coming in from some sponsors next year due to the financial impact those organizations are facing as well.

And that can be tough.

“When we cancel, our whole staff is involved — from the box audience and public engagement folks to the technical production team and our front-of-house staff,” Swanson said.

“Our communication is key in talking through it all and then sharing clear messages with our audiences, especially in terms of refunds. But we’ve been encouraged by so many generous friends of Hancher donating their ticket purchase price back to us.”

While disappointment still is thick in the air, organizations don’t plan to abandon their missions and is keeping an eye on serving the public.

“This is a challenging time for everyone, and our board and staff is committed to finding creative and non-traditional solutions to ensure the Freedom Festival’s return,” Johnson said. “The community and our stakeholders have been tremendous supports of the Freedom Festival and we believe they will continue to do so in the future.

“We ask for understanding and patience as we try to navigate this crisis and what we can still provide for our community.”

Freedom Festival buttons will be sold this year as they’ve already been made, and “It’s a way the community can show their support,” Johnson said.

Barnes agreed and noted the Iowa Arts Festival committee is working on ways to support the performers, artists and vendors they had scheduled by trying to develop some virtual opportunities for engagement.

While the show, or events, might not go on, organizers said they very much want to remain connected to their audiences and attendees.

“I want to make sure everybody knows we care about them and that we’re trying to find ways to stay connected because I think we’re all in this together and the arts are one of the best ways for people to get through difficult times,” Swanson said.

Myers agreed.

“Indian Creek Nature Center will be ready to welcome guests and visitors back to our events as soon as we are able to do so safely,” he said.

“In the meantime, we hope everyone finds peace in nature by taking a hike or bike ride, having a picnic or just enjoying time outside.”

Weak-strong uniqueness for an elastic plate interacting with the Navier Stokes equation. (arXiv:2003.04049v2 [math.AP] UPDATED)

We show weak-strong uniqueness and stability results for the motion of a two or three dimensional fluid governed by the Navier-Stokes equation interacting with a flexible, elastic plate of Koiter type. The plate is situated at the top of the fluid and as such determines the variable part of a time changing domain (that is hence a part of the solution) containing the fluid. The uniqueness result is a consequence of a stability estimate where the difference of two solutions is estimated by the distance of the initial values and outer forces. For that we introduce a methodology that overcomes the problem that the two (variable in time) domains of the fluid velocities and pressures are not the same. The estimate holds under the assumption that one of the two weak solutions possesses some additional higher regularity. The additional regularity is exclusively requested for the velocity of one of the solutions resembling the celebrated Ladyzhenskaya-Prodi-Serrin conditions in the framework of variable domains.

On $p$-groups with automorphism groups related to the exceptional Chevalley groups. (arXiv:1810.08365v3 [math.GR] UPDATED)

Let $hat G$ be the finite simply connected version of an exceptional Chevalley group, and let $V$ be a nontrivial irreducible module, of minimal dimension, for $hat G$ over its field of definition. We explore the overgroup structure of $hat G$ in $mathrm{GL}(V)$, and the submodule structure of the exterior square (and sometimes the third Lie power) of $V$. When $hat G$ is defined over a field of odd prime order $p$, this allows us to construct the smallest (with respect to certain properties) $p$-groups $P$ such that the group induced by $mathrm{Aut}(P)$ on $P/Phi(P)$ is either $hat G$ or its normaliser in $mathrm{GL}(V)$.

Groups up to congruence relation and from categorical groups to c-crossed modules. (arXiv:2005.03601v1 [math.CT])

We introduce a notion of c-group, which is a group up to congruence relation and consider the corresponding category. Extensions, actions and crossed modules (c-crossed modules) are defined in this category and the semi-direct product is constructed. We prove that each categorical group gives rise to c-groups and to a c-crossed module, which is a connected, special and strict c-crossed module in the sense defined by us. The results obtained here will be applied in the proof of an equivalence of the categories of categorical groups and connected, special and strict c-crossed modules.

Filtered expansions in general relativity II. (arXiv:2005.03390v1 [math-ph])

This is the second of two papers in which we construct formal power series solutions in external parameters to the vacuum Einstein equations, implementing one bounce for the Belinskii-Khalatnikov-Lifshitz (BKL) proposal for spatially inhomogeneous spacetimes. Here we show that spatially inhomogeneous perturbations of spatially homogeneous elements are unobstructed. A spectral sequence for a filtered complex, and a homological contraction based on gauge-fixing, are used to do this.

A Note on Cores and Quasi Relative Interiors in Partially Finite Convex Programming. (arXiv:2005.03265v1 [math.FA])

The problem of minimizing an entropy functional subject to linear constraints is a useful example of partially finite convex programming. In the 1990s, Borwein and Lewis provided broad and easy-to-verify conditions that guarantee strong duality for such problems. Their approach is to construct a function in the quasi-relative interior of the relevant infinite-dimensional set, which assures the existence of a point in the core of the relevant finite-dimensional set. We revisit this problem, and provide an alternative proof by directly appealing to the definition of the core, rather than by relying on any properties of the quasi-relative interior. Our approach admits a minor relaxation of the linear independence requirements in Borwein and Lewis' framework, which allows us to work with certain piecewise-defined moment functions precluded by their conditions. We provide such a computed example that illustrates how this relaxation may be used to tame observed Gibbs phenomenon when the underlying data is discontinuous. The relaxation illustrates the understanding we may gain by tackling partially-finite problems from both the finite-dimensional and infinite-dimensional sides. The comparison of these two approaches is informative, as both proofs are constructive.

Non-relativity of K"ahler manifold and complex space forms. (arXiv:2005.03208v1 [math.CV])

We study the non-relativity for two real analytic K"ahler manifolds and complex space forms of three types. The first one is a K"ahler manifold whose polarization of local K"ahler potential is a Nash function in a local coordinate. The second one is the Hartogs domain equpped with two canonical metrics whose polarizations of the K"ahler potentials are the diastatic functions.
