Nonlinear behaviour of pulsating white dwarfs [PDF]

open access: yes, 1999
Bibliography : p. 199-207.Using a phenomenological approach, I have investigated the nonlinear properties of the pulsations of two white dwarfs, namely DA G29-38 and DB GD358. The data at my disposal comprised numerous single- and multi-sites time series

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

open access: yesOikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Using 3.4 μm Variability toward White Dwarfs as a Signpost of Remnant Planetary Systems

open access: yesThe Astrophysical Journal
Roughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their double-peaked emission at the near-infrared calcium triplet.

Cool versus ultracool white dwarfs [PDF]

open access: yes, 2005
A preliminary BVRIJHK analysis of the white dwarfs SSSPM J2231-7514 and SSSPM J2231-7515 is presented. Although both stars were reported to have T eff < 4000 K, the analysis here indicates T eff ≈ 4250 K for both SSSPM J2231-7514 and SSSPM J2231-7515 ...

Exploring consumer preferences for wild meat and other animal proteins in Gamba, Gabon: Implications for conservation and management of natural resources alongside extractive industry

open access: yesPeople and Nature, EarlyView.
Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Sources of Strength for School‐Based Suicide Prevention: Key Implementation Strategies Based on School Professional Perspectives

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT As concerns for rising rates of youth suicide and suicidal thoughts and behaviors continue to grow, there is a need to prioritize school‐based suicide prevention programs. Despite evidence documenting the effectiveness of school‐based prevention programs for reducing suicide‐related risk in adolescents, schools face numerous barriers to ...

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

From wild to tamed: Reimagining novel crops through omics and local plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.
