Developing an understanding of American elderberry (Sambucus nigra subsp. canadensis (L.) Bolli) to support breeding efforts

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Elderberries (Sambucus spp.) have been valued as food and medicine around the world for millennia. Elderberry products are experiencing an increase in demand as ongoing research substantiates their putative health benefits. European elderberries (Sambucus nigra subsp. nigra) are an established industry in Europe and are often imported into the

POSITIVE AND NEGATIVE SUPERHUMPS OF THE DWARF NOVA MN DRA

open access: yesOdessa Astronomical Publications, 2010
We present the result of O–C analysis of the dwarf nova MN Dra. It is based on the multi-site photometric observations that were made over 77 nights in August – November, 2009. The total exposure was 433 hours.

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

NON-THERMAL EMISSION FROM CATACLYSMIC VARIABLES: IMPLICATIONS ON ASTROPARTICLE PHYSICS

open access: yesActa Polytechnica, 2013
We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation. It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, polars, and classical novae ...

Deriving an X-ray luminosity function of dwarf novae based on parallax measurements [PDF]

open access: yes, 2010
We have derived an X-ray luminosity function using parallax-based distance measurements of a set of 12 dwarf novae, consisting of Suzaku, XMM–Newton and ASCA observations.

Conservation challenges and opportunities for native apple (Malus) species in Canada

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Outburst Properties of V1504 Cyg and V344 Lyr

open access: yesActa Polytechnica CTU Proceedings, 2015
I begin by reviewing dwarf novae and the disk instability theory, and then present an overview of three ideas for producing superoutbursts in the SU UMa stars − the thermal tidal instability, irradiation-induced secondary mass overflow, and the plain ...

Exploring the complexities of cooperative breeding: insights from African wild dog packs

open access: yesJournal of Zoology, Volume 328, Issue 1, Page 16-29, January 2026.
Across 14 years of monitoring African wild dog packs in Savé Valley Conservancy, Zimbabwe, we found that younger and larger packs were significantly more likely to produce multiple litters, with second‐born pups showing higher survival. Pup survival also increased with pack size, rainfall, and alpha female age, highlighting the adaptive benefits of ...

Novae: An Important Source of Lithium in the Galaxy

open access: yesThe Astrophysical Journal
The source of the Galactic lithium (Li) has long been a puzzle. With the discovery of Li in novae, extensive research has been conducted. However, there still exists a significant disparity between the observed abundance of Li in novae and the existing ...

Data mining for dwarf novae in SDSS, GALEX and astrometric catalogues [PDF]

open access: yes, 2009
By cross-matching blue objects from the Sloan Digital Sky Survey with Galaxy Evolution Explorer and the astrometric catalogues USNO-B1.0, GSC2.3 and CMC14, 64 new dwarf nova candidates with one or more observed outbursts have been identified. 14 of these
