MBC now has 150 accessions of C. micronesica from 24 different populations — the most complete single-species representation of any cycad in MBC’s collection. With native C. micronesica populations declining rapidly, the crucial role of ex situ conservation collections has Cycas micronesica population on Rota, devastated by CAS never been clearer — Montgomery Botanical Center is work- ing directly to prevent extinction of cycad populations. a straight transect. This presented an enormous challenge as Guam has very rugged terrain, abundant limestone cliffs, and areas of scrub forest with virtually impenetrable veg- etation. Moreover, scale had infested the entire island and, in several populations, over 80 percent of standing cycads were dead — finding live plants in the correct transect location was difficult. In some populations, cone produc- tion had ceased entirely and seeds could not be found. In the 17 populations I visited in Guam, I observed only one, single-leaf seedling, likely to soon succumb to scale.

BDepartment of Ophthalmology, University of British Columbia, Vancouver, British Columbia, Canada V6T 1Z4. CCorresponding author. Email: [email protected] Abstract. Neurotoxins contained in the seeds of Cycas micronesica K.D. Hill have been implicated in the Guam neurological disease cluster, amyotrophic lateral sclerosis–parkinsonism dementia complex (ALS–PDC). Some of these neurotoxins remain in the washed cycad seed flour that was historically an important part of the Chamorro diet. Of these, variant steryl glucosides have been identified by us as a possible etiological factor in the disease. In vitro and in vivo animal studies have strongly supported a role for these molecules in some forms of neurodegeneration. As part of a series of studies, we have now determined the concentrations of several steryl glucosides and their sterol precursors as affected by the age of C. micronesica seeds. The concentration of these molecules declined with seed age from 2.0 to 30.5 months. Following log-transformation of both axes, the decline was linear. Similarly, concentration of all but one of the molecules declined with age when samples were restricted to gametophyte tissue. Factors suspected of influencing phenotypic plasticity must be addressed when interpreting plant physiology data. Our results confirm for the first time that tissue age must be documented and reported in cycad seed biochemistry studies to remove ambiguities from results.

Recently, an aggressive pest on cycads, the cycad aulacaspis scale (CAS)— Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)—has spread through human activity and commerce to the point where two species of cycads face imminent extinction in the wild. Given its mission of cycad conservation, we believe the CSG should clearly focus its attention on mitigating the impact of CAS on wild cycad populations and cultivated cycad collections of conservation importance (e.g., Montgomery Botanical Center). The control of CAS in home gardens, commercial nurseries, and city landscapes is outside the scope of this report and is a topic covered in various online resources (see www.montgomerybotanical.org/Pages/CASlinks.htm).

    REQUEST FOR STATEMENTS OF INTEREST N40192-21-2-8003 PROJECT TO BE INITIATED IN FISCAL YEAR 2021 Project Title: CYCAD MONITORING AT ANDERSEN AIR FORCE BASE (AAFB) AND TINIAN MILITARY LEASE AREA (MLA) Responses to this Request for Statements of Interest will be used to identify potential projects to be funded by the Department of the Navy (DoN) in support of monitoring the Cycas micronesica plants currently at Andersen Air Force Base (AAFB), Guam and the Tinian Military Lease Area (MLA). Approximately $219,491 is expected to be available to support this program (contingent upon availability of funds). The Department of Navy’s obligation to pay or reimburse any costs hereunder is subject to the availability of appropriated funds and limited by funds obligated and nothing in this Agreement will be interpreted to require obligations or payments by the Federal Government in violation of the Anti-Deficiency Act, 31 U.S.C. §1341. Thus, funds have not yet been appropriated for this project and there is considerable uncertainty regarding the level of available funding for FY2021. Background Fadang or Micronesian cycad (Cycas micronesica), an endemic plant found on the islands of Guam and Rota, was the dominant plant and the most abundant ‘tree’ in Guam’s forests in 2000. The invasion of the cycad scale Aulacaspis yasumatsui in 2003 and the butterfly Luthrodes pandava (formerly known as Chilades pandava) in 2005 initiated an epidemic mortality of plant populations such that C. micronesica was Red- listed by the IUCN as endangered in 2006 and listed as threatened under the U.S.

  • Elemental Profiles in Cycas Micronesica Stems
    plants Article Elemental Profiles in Cycas micronesica Stems Thomas E. Marler College of Natural and Applied Sciences, University of Guam, UOG Station, Mangilao, Guam 96923, USA; [email protected]; Tel.: +1-671-735-2100 Received: 24 August 2018; Accepted: 30 October 2018; Published: 1 November 2018 Abstract: Essential nutrients and metals have been quantified in stems of many tree species to understand the role of stems as storage and source organs. Little is known about stored stem resources of cycad tree species. Cycas micronesica tissue was collected from apical and basal axial regions of stems; and pith, vascular, and cortex tissues were separated into three radial regions. Leaves were also sampled to provide a comparison to stems. Minerals and metals were quantified in all tissues. Minerals and metals varied greatly among the six stem sections. Phosphorus varied more among the three radial sections than the other macronutrients, and zinc and nickel varied more than the other micronutrients. Stem carbon was less than and stem calcium was greater than expected, based on what is currently known tree stem concentrations in the literature. Elemental concentrations were generally greater than those previously reported for coniferous gymnosperm trees. Moreover, the stem concentrations were high in relation to leaf concentrations, when compared to published angiosperm and conifer data. The results indicated that the addition of more cycad species to the literature will improve our understanding of gymnosperm versus angiosperm stem nutrient relations, and that the non-woody cycad stem contains copious essential plant nutrients that can be mobilized and deployed to sinks when needed.

ORCID: https://orcid.org/0000-0002-2515-6509 * Corresponding author: [email protected] Significance Statement Knowledge of how thermal tolerances are distributed across major clades and biogeographic regions is important for understanding biome formation and climate change responses. However, most research has concentrated on animals, and we lack equivalent knowledge for other organisms. Here we compile global data on heat and cold tolerances of plants, showing that many, but not all, broad-scale patterns known from animals are also true for plants. Importantly, failing to account simultaneously for influences of local environments, and evolutionary and biogeographic histories, can mislead conclusions about underlying drivers. Our study unravels how and why plant cold and heat tolerances vary globally, and highlights that all plants, particularly at mid-to-high latitudes and in their non-hardened state, are vulnerable to ongoing climate change. Abstract Thermal macrophysiology is an established research field that has led to well-described patterns in the global structuring of climate adaptation and risk. However, since it was developed primarily in animals we lack information on how general these patterns are across organisms. This is alarming if we are to understand how thermal tolerances are distributed globally, improve predictions of climate change, and mitigate effects.

Marler 1,* 1 College of Natural and Applied Sciences, University of Guam, Mangilao, GU 96923, USA; [email protected] (B.E.D.); [email protected] (L.S.Y.) 2 School of Biological Sciences, University of Utah, Salt Lake City, UT 84112, USA; [email protected] * Correspondence: [email protected] Received: 7 November 2020; Accepted: 7 December 2020; Published: 16 December 2020 Simple Summary: Effective conservation of endangered plant species requires identifying their greatest threats to formulate management protocols. Invasive species are a result of global change and are a major threat to biodiversity. We used the island cycad Cycas micronesica K.D. Hill as a model that represents the global issues of conservation science and invasion biology. In Guam, several non-native insect invasions began in 2003 and have combined to threaten the island population of this cycad species. In this article, we summarize the history of reported invasions and the reported non-native insect herbivores that have recently increased the threat status. We also discuss the interactions among herbivores that threaten the sustainability of C. micronesica on the island of Guam. Abstract: Invasions of non-native species can threaten native biodiversity, and island ecosystems are ideal for studying these phenomena. In this article, first, we report on the invasive species that combine to threaten the island cycad Cycas micronesica by reviewing the history of previously reported invasions and providing an update of recent invasions.
