Native plants are the answer…

by

Maybe it’s just me, but it seems to me that there are far too many crepe myrtles (Lagerstroemia sp.) in use for the good of the planet, especially for the good of wildlife in the United States.

The same could be said of other exotic plants, such as Privet or Ligustrum (Ligustrum sp.), Heavenly Bamboo (Nandina domestica),   Chinaberry (Melia azedarach), and others. Even plants native to one area might become invasive if introduced and allowed to spread in another ecoregion.

Best advice, of course, is to plant plants that are native to your ecoregion. And with Climate Change (or Climate Chaos, which seems to be a more accurate description), even plants native to one’s ecoregion might be getting squeezed out or moving further north, or moving higher up, or retreating into ecological niches (if they haven’t been paved over or bulldozed into oblivion).

Texas Lantana (Lantana urticoides)

Take, for instance, Texas Lantana (Lantana urticoides) which can often be found, even in the “big box” stores. However, its cousin Lantana camara which is similar but has different colored flowers and somewhat different leaf texture (I am told) can also be found in those same stores which don’t offer plants grown only in the local region. So it shouldn’t have surprised me when I found several of the L. camara in the greenbelt this past fall, growing right beside what I took to be L. urticoides. And while trying to get photos of a stand of native Solidago sp., (aka Goldenrod), I chanced upon a young Chinaberry (Melia azedarach) sapling. Nearby there are several invasive Chinese pistache (Pistacia chinensis). And that’s just directly behind my house and/or my neighbors’ houses.

This, in a greenbelt that is protected because there is a cavern underneath it within which live one or two endangered species.

The conclusion is the title to this post.

PLANT GRASSES, FLOWERS, SHRUBS AND TREES THAT ARE NATIVE TO THE AREA IN WHICH YOU LIVE. NOTHING ELSE.

If you want a Crepe Myrtle in your yard, then move to Southeast Asia, or wherever it is that they’re from. And take the big-box store nurseries with you. Please. Thank you.

p.s. drove past the construction site where I had taken photos on September 23, 2020, and it appears that most of the native plants have been the subject of “brush clearing.” Don’t know for sure. Didn’t stop and inspect. Would think the Winecups might be in bloom, either now or soon.

More physical therapy, more research & guidelines

by

Perhaps it is because one is in rehabilitation, that one’s interest turns towards rehabilitation and Parkinson’s Disease. Sounds like a reasonable explanation.

This article from 2017 looked at rates of utilization of rehabilitative services, looking at several demographics:  Utilization of rehabilitation therapy services in Parkinson disease in the United States    (This article is on PubMed and is open access).

  The authors. …”found that 75% of Medicare beneficiaries diagnosed with PD did not receive rehabilitative therapies over a 36-month period. While it is not clear what the appropriate utilization rate should be, utilization among patients with PD in the Netherlands and the United Kingdom greatly exceeds what we found in the United States: at least 57% and 54%, respectively., In this study, predictors of higher (but still low) rates of therapy utilization included PD care by a neurologist, Asian or Caucasian race, and geographic location. 

The NICE folks in the UK have a link where one may download their entire set of guidelines for treatment of people with Parkinson’s:

Parkinson’s disease in adults

After looking at their recommendations on DBS, I’m not sure I am in total agreement with them there. But other that, they seem to be solid, aimed at the general practitioner, though, not to the Movement Disorders Specialist (my impression).

This article is not available for open access, but here’s the citation:

Rafferty, M.R., Nettnin, E., Goldman, J.G. et al. Frameworks for Parkinson’s Disease Rehabilitation Addressing When, What, and How. Curr Neurol Neurosci Rep 21, 12 (2021). https://doi.org/10.1007/s11910-021-01096-0

There is moderate to strong evidence supporting physical therapy, occupational therapy, and speech-language pathology soon after diagnosis and in response to functional deficits.

We propose a framework of three pathways for rehabilitation care:

(1) consultative proactive rehabilitation soon after diagnosis for assessment, treatment of early deficits, and promotion meaningful activities;

(2) restorative rehabilitation to promote functional improvements; and

(3) skilled maintenance rehabilitation for long-term monitoring of exercise, meaningful activities, safety, contractures, skin integrity, positioning, swallowing, and communication.   (emphasis added).

I would agree with the overall framework – I have had some postural issues since the beginning (pre-PD), and assessment and promotion of meaningful activities would have been helpful. I did receive some physical. therapy to correct posture, which did so, only to reveal spinal stenosis.  Later on, I had bunionectomies which kept me wheelchair bound or with limited mobility for a year, and restorative rehabilitation was provided and needed. Finally, my own hubris regarding my mobility led to several falls in 2019 and 2020, and are now being addressed with both restorative rehabilitation and skilled maintenance rehabilitation which will hopefully correct the problems and provide the the tools to maintain posture, etc. over the (hopefully) years to come.

The polar vor-Texas of 2021

by

 

 

Or, that was the week that was…

On February 11, went outside and snapped these – oak leaves encased in ice, desert willow branches looking more like Apache plume, Opuntia dripping icicles and a frozen “heart”, icicles  hanging from. a cholla tree cactus, frozen Ashe juniper leaves,, brave little four nerve daisy, and Mexican feather grass icy swirls. 

Those were taken on February 11. And yet, there was more to come. On February 15,  2021,   the Four nerve daisy sticking it out above the accumulation.The berm, completely covered by 6 inches of snow, avng been mowed below 4 inches in January, a Texas persimmon leaf encased in ice, an icy silhouette, and a tangled web of branches. Finally, on the 20t, things  bega to start thawing out.

It’s PT (Physical Therapy) time again

by

I have described myself as “71 going on 17” frequently enough lately to others that isn’t getting funny anymore. But a couple of things have happened that go beyond a palindromic allusion to the soundtrack from “The Sound Of Music.”

On March 27, 2019, I was reaching over a landscape boulder in my yard, trying to put in place a sun shade umbrella stand that would serve as a solar panel stand for a small water feature, when I lost my balance, fell forward, and broke my fall with my left hand. I was actually in physical therapy at the time for rehabilitation following a couple of bunionectomies on the same foot, so after X-rays confirmed there was no fracture, I continued with both rehabs. This past October, 2020, I managed to step off a different landscape boulder in my yard with no apparent damage while falling on my back. Then later in the month, on the 24th and 31st, while out photographing wildflowers in a preserve, I fell backwards stepping off – again, no apparent damage. On the 31st, I attempted to catch up with the group I was with by taking a shortcut, stepping up on a boulder using my walking stick. I almost made it, but teetered and fell backwards. Fortunately there were no apparent fractures. But it did make the symptoms from the 2019 return. Short story long – my Primary Care Provider referred me to rehab, I was assigned to a PT who had seen me before, and she quickly focused in on the worst pain, and then worked on the other, postural habits and problems that continued to cause problems. And noted that when I step up, I tend to lean back, which probably had something to do with my October 31 fall.

All of which is a roundabout way to lead in to this review article: Physiotherapy in Parkinson’s Disease:A Meta-Analysis of Present Treatment Modalities   

Results:

  •  Conventional physiotherapy significantly improved motor symptoms, gait, and quality of life.
  • Resistance training improved gait.
  • Treadmill training improved gait.
  • Strategy training improved balance and gait.
  • Dance, Nordic walking, balance and gait training, and martial arts improved motor symptoms, balance, and gait.
  • Exergaming improved balance and quality of life.
  • Hydrotherapy improved balance.
  • dual task training did not significantly improve any of the outcomes studied.

Some research that might be of interest…

by

My Google Scholar alert feed tossed a couple of items my way  that might be of interest. They are in PDF format, so you can read them online or download them for future reference:

Tricky partners: native plants show stronger interaction preferences than their exotic counterparts.

Citation: Coux, C., I. Donoso, J. M. Tylianakis, D. Garcı´a, D. Martı´nez, D. M. Dehling, and D. B. Stouffer. 2021. Tricky partners: native plants show stronger interaction preferences than their exotic counterparts Ecology 102(2):e03239. 10.1002/ecy.3239

Main takeaway (my interpretation): Increasing presence of exotic plants may put rare native plants at higher risk of extinction.

(Caveat: my browser says the site is not secure. However, I have several security programs that (hopefully) would mitigate. the risks).

That being said, the article is from a group of scientists from New Zealand, Germany and Spain who looked into the interactions that native and exotic plant species had with other plant species.

Exotic species interact with many partners with which they have not coevolved, and it remains unclear whether this systematically influences the strength of neutral processes on interactions, and how these interaction-level differences scale up to entire networks. To fill this gap, we compared interactions between plants and frugivorous birds at nine forest sites in New Zealand varying in the relative abundance and composition of native and exotic species, with independently sampled data on bird and plant abundances from the same sites

The results found that native plants’ interactions with birds were both more positive (preference for) and negative (avoidance of). Their analysis suggests that the blending of species communities through dispersal of exotics into native plant communities might result in an increase of neutral interactions between birds and native plants or exotic plants.

This could make rare species more vulnerable to this loss of selectivity and to greater randomness in the identity of their interaction partner.

So there’s another argument for getting rid of invasives.

Moving right along, here comes

Where Have the Native Grasses Gone: What a LongTerm Repeat Study Can Tell Us about California’s Native Prairie Landscapes

…found that native grass cover decreased dramatically (especially on the valley floor), exotic grass cover fluctuated widely over time, while both native and exotic forb cover increased over time. The findings support the notion that prior grazing management practices may have supported the former stands of Stipa pulchra.

… Several trends became apparent when the data from the three periods are viewed together. Both native and exotic forbs increased between each data collection. There were consistently more native forbs than exotic ones and native grasses decreased in cover. Though exotic grasses fluctuated, they always made up a greater amount of cover than their native counterparts. Lastly, cover of bare ground fluctuated and shrubs declined. The Fisher’s Exact test of the increases and decreases of forb and grass cover across quadrats from 1981 to 2015 had a p-value of 0.00012 indicating that we can reject the null hypothesis of independence…

… native bunchgrasses have declined dramatically since the end of the ranching era. Simultaneously, native forbs have increased (at least temporarily), especially on the valley floor. Our findings also suggest that the historical ranching practices in LJV likely supported the excellent stands of Stipa observed in the valley prior to release from grazing. These findings are in agreement with those of previous long-term studies in other parts of California that also found a decline in Stipa cover on lands released from grazing. (emphasis added).

If one were to generalize the conclusions of this study to Texas, where this writer resides, I would say that the presence of large stands of Prickly Pear (Opuntia sp.). and Texas Cedars (Juniperus ashei) as the dominant species in large parts of Central Texas is probably due to past practices of overgrazing, similar to the presence of the native bunchgrasses in California has been attributed to the previous grazing practices in the study cited above.

However, I do not believe that the answer to the problem is to bulldoze the soil away and to cover the land with non-permeable surfaces like buildings and asphalt parking lots.  One can develop land while leaving large portions of native plant species intact, and without replacing them with crappy myrtles and Nandina plants.

postscript:

One of the references used in the article on California grasses was California’s Fading Wildflowers  by Richard A. Minnich. The table of contents and lists of illustrations and tables and preface are available for open access, but the book itself costs a hefty $128.00.  Another reference was Terrestrial Vegetation of California.

Cannabis and Parkinson’s Disease (PD)

by

This article popped up in my email alerts. Although I do not have access to the journal in which it appeared, I thought I would post it anyway, along with several article titles that appeared in the same journal. (If my former employer would grant me access to their technical library, I would be most grateful, and might even forego any patent filing awards that I would be eligible for if I hadn’t retired. I come across at least one new Human-Computer Interface issue that could be solved each week, But I digress). (The actual link to the article was in Medscape News).

Despite high interest (no pun intended(?)) in the use of cannabis as a treatment for Parkinson’s Disease symptoms, this study  finds that actual use remains low (at least in Germany). The article appeared in  Journal of Parkinson’s Disease: Yenilmez, Ferhat et al. ‘Cannabis in Parkinson’s Disease: The Patients’ View’. 1 Jan. 2021 : 309 – 321. 11, no. 1, pp. 309-321, 2021.

Sadly, it is not available as open access, but fortunately the methods and results provide adequate data regarding the study.

Abstract:

Background: Little is known about the patients’ view on treatment with medical cannabis (MC) for Parkinson’s disease (PD). Objective: To assess the PD community’s perception of MC and patients’ experience with MC.Abstract:

Methods: Applying a questionnaire-based survey, we evaluated general knowledge and interest in MC as well as the frequency, modalities, efficacy, and tolerability of application. Questionnaires were distributed nationwide via the membership journal of the German Parkinson Association and locally in our clinic to control for report bias.

Results: Overall, 1.348 questionnaires (1.123 nationwide, 225 local) were analysed. 51% of participants were aware of the legality of MC application, 28% of various routes of administration (ROA) and 9% of the difference between delta9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD).

PD-related cannabis use was reported by 8.4% of patients and associated with younger age, living in large cities and better knowledge about the legal and clinical aspects of MC. Reduction of pain and muscle cramps was reported by more than 40% of cannabis users. Stiffness/akinesia, freezing, tremor, depression, anxiety and restless legs syndrome subjectively improved for more than 20% and overall tolerability was good. Improvement of symptoms was reported by 54% of users applying oral CBD and 68% inhaling THC-containing cannabis. Compared to CBD intake, inhalation of THC was more frequently reported to reduce akinesia and stiffness (50.0% vs. 35.4%; p < 0.05). (emphasis added) Interest in using MC was reported by 65% of non-users.

Conclusion: MC is considered as a therapeutic option by many PD patients. Nevertheless, efficacy and different ROA should further be investigated.

The adjusted odds ratios (ORs) in model 2, which was adjusted for all potential confounders, for hypothyroidism and hyperthyroidism in the PD group were 1.25 (95% confidence interval (CI) 1.01–1.55, p  = 0.044) and 1.37 (95% CI 1.13–1.67, p  = 0.002), respectively.
