Initial Recovery of the Herbaceous Layer of a Temperate Deciduous Forest After 30 Years of Nitrogen Amendments: Implications for the Success of the Clean Air Act

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...

Interspecies evolutionary divergence in Liriodendron, evidence from the nucleotide variations of LcDHN-like gene

open access: yesBMC Evolutionary Biology, 2018
Background Liriodendron is a genus of Magnoliaceae, which consists of two relict species, Liriodendron chinense and L. tulipifera. Although the morphologies are highly similar, the two species exhibit different adaptive capacity.

True and False Foodplants of \u3ci\u3eCallosamia Promethea\u3c/i\u3e (Lepidoptera: Saturniidae) in Southern Michigan [PDF]

open access: yes, 2017
A survey in 1980 of the associations of over 400 cocoons of Callosamia promethea Drury in vegetation along and adjacent to southern Michigan roadsides gave evidence for seven species of true larval foodplants (not including two others known in the area ...

New Reports of Exotic and Native Ambrosia and Bark Beetle Species (Coleoptera: Curculionidae: Scolytinae) From Ohio [PDF]

open access: yes, 2018
In a 2007 survey of ambrosia and bark beetles (Coleoptera: Curculionidae: Scolytinae) along a transect in northeastern Ohio, we collected six exotic and three native species not previously reported from the state.

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2933-2945, June 2026.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Absence of Behavioral Induction in Oviposition Preference of \u3ci\u3ePapilio Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2017
This study addressed the possible behaviora induction effects of previous exposure to several specific host plants on subsequent host preference hierarchy and specificity (i.e ..

Structure and sequence evolution in the pennycress (Thlaspi arvense) pangenome

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2723-2741, June 2026.
Summary Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biodiversity. Harnessing this variation for agriculture hinges on our ability to detect, quantify, catalog, and deploy genetic diversity. Here, we explore seven

Antifungal Effects of Volatile Organic Compounds Produced by Rahnella aquatilis JZ-GX1 Against Colletotrichum gloeosporioides in Liriodendron chinense × tulipifera

open access: yesFrontiers in Microbiology, 2020
The use of volatile organic compounds (VOCs) produced by microorganisms for the biological control of plant diseases has attracted much attention in recent years.

Classification and Protection Status of Remnant Natural Plant Communities in Arkansas [PDF]

open access: yes, 1981
A classification and inventory of Arkansas\u27s remaining tracts of relatively undisturbed vegetation was initiated in 1979. Based on extensive literature surveys and field work, the classification includes five physiognomic classes, 17 cover classes ...

Dendrológiai kertek a 19. századi magyarországi kertépítészetben = Dendrological gardens in 19th century garden architecture in Hungary [PDF]

open access: yes, 2014
Disszertációm elsődleges célja, hogy összegyűjtsem azokat a még létező és már nem létező magyar tájképi kerteket, amelyek növényalkalmazásában és kerti térkompozíciójának kialakításában a különböző egzóta fafajok jelentős szerepet játszottak.
