Stable isotope mixing models demonstrate the role of an invasive plant in wetland songbird food webs. [PDF]

Appl Plant Sci, 2022
Abstract Premise Invasive plants in wetlands are often ecosystem engineers, mediating changes in ecosystem functions like trophic support. We documented the impacts of Lepidium latifolium, an invasive plant, on the food web of omnivorous birds (Suisun song sparrows, Melospiza melodia maxillaris) in a tidal wetland of northern California, USA.

Two dominant forms of multisite similarity decline - Their origins and interpretation. [PDF]

Ecol Evol, 2023
Comparison of diversity patterns for the two dominant forms of multisite similarity decline (a) decline in similarity (b) species accumulation. Abstract The number of species shared by two or more sites is a fundamental measure of spatial variation in species composition.

Advancements in Coronary Bifurcation Stenting Techniques: Insights From Computational and Bench Testing Studies. [PDF]

Int J Numer Method Biomed Eng
This review article examines computational and bench testing approaches in coronary bifurcation stenting, focusing on procedural strategies, stent design, and patient‐specific factors. Key findings highlight the potential of computational methods, such as finite element analysis and computational fluid dynamics, to assess stent performance, optimize ...

Differences in mucilage properties and stomatal sensitivity of locally adapted Zea mays in relation with precipitation seasonality and vapour pressure deficit regime of their native environment

Plant Direct, Volume 7, Issue 8, August 2023., 2023
Abstract With ongoing climate change and the increase in extreme weather events, especially droughts, the challenge of maintaining food security is becoming ever greater. Locally adapted landraces of crops represent a valuable source of adaptation to stressful environments.

C−S Cross‐Coupling Reactions Catalyzed by Well‐Defined Copper and Nickel Complexes

European Journal of Organic Chemistry, Volume 2022, Issue 31, August 19, 2022., 2022
The use of well‐defined organometallic copper and nickel complexes in the formation of C−S bonds by C−S cross coupling reactions is described. They have the advantage over those based on precious metals such as Pd, of being two of the most abundant metals in the earth's crust and thus, are much cheaper.

Physiology as a tool for at‐risk animal recovery planning: An analysis of Canadian recovery strategies with global recommendations

Conservation Science and Practice, Volume 4, Issue 6, June 2022., 2022
Abstract Many government organizations use recovery planning to synthesize threats, propose management strategies, and determine recovery criteria for threatened wildlife. Little is known about the extent to which physiological knowledge has been used in recovery planning, despite its potential to offer key biological information that could aid in ...

Predation risk can modify the foraging behaviour of frugivorous carnivores: Implications of rewilding apex predators for plant–animal mutualisms

Journal of Animal Ecology, Volume 91, Issue 5, Page 1024-1035, May 2022., 2022
Red fox (Vulpes vulpes) foraging placidly on Iberian pear fruits (Pyrus bourgaeana) in one fruit depot created for the field experiment of this study outside Iberian lynx (Lynx pardinus) ranges. Abstract Apex predators play key roles in food webs and their recovery can trigger trophic cascades in some ecosystems.

Note sur l'"Angleton grass" Dichanthium aristatum (Poir.) Hubb

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1967
Les effets du sulfate d'ammonium sur la production de fourrage vert, de matière sèche et de foin de l'herbe d'Angleton sont étudiés. Les résultats de l'expérience permettent de conclure que: a) il augmente la production de fourrage vert et de matière ...
