The transition from germinating seeds to emerging seedlings is one of the most vulnerable plant life cycle stages. Heteromorphic diaspores (seed and fruit dispersal units) are an adaptive bet-hedging strategy to cope with spatiotemporally variable en

Publikováno v: Avian Research, Vol 11, Iss 1, Pp 1-10 (2020)

Abstract Background The allocation of resources between offspring size and number is a central question of life-history theory. Although several studies have tested the existence of this trade-off, few studies have investigated how environmental vari

Suppression of Seedling Survival and Recruitment of the Invasive Tree Prosopis juliflora in Saudi Arabia through Its Own Leaf Litter: Greenhouse and Field Assessments

Autor: Ahmed M. Abbas, Maryam M. Alomran, Nada K. Alharbi, Stephen J. Novak

Publikováno v: Plants, Vol 12, Iss 4, p 959 (2023)

Many studies have focused on how leaf litter depth affects seed germination and seedling growth because the seedling stage is the most vulnerable portion of a plant’s life cycle. Invasive plants with the most severe ecological consequences are thos

Germination of Seeds from Flowers along a Continuum of Long to Short Styles in the Cold Desert Perennial Herb Ixiolirion songaricum

Autor: Juanjuan Lu, Haiyan Yi, Dunyan Tan, Carol C. Baskin, Jerry M. Baskin

Publikováno v: Plants, Vol 11, Iss 11, p 1452 (2022)

We compared seed set, mass, and dormancy/germination of seeds from flowers at three points on the style-length continuum [long (LS), intermediate (IS), and short (SS) styles] in Ixiolirion songaricum. The effects of open and hand pollination (self an

Bacillus subtilis Nucleoid-Associated Protein YlxR Is Involved in Bimodal Expression of the Fructoselysine Utilization Operon (frlBONMD-yurJ) Promoter

Autor: Mitsuo Ogura, Kazutoshi Shindo, Yu Kanesaki

Publikováno v: Frontiers in Microbiology, Vol 11 (2020)

Bacteria must survive harsh environmental fluctuations at times and have evolved several strategies. “Collective” behaviors have been identified due to recent progress in single-cell analysis. Since most bacteria exist as single cells, bacterial

Aphids Facing Their Parasitoids: A First Look at How Chemical Signals May Make Higher Densities of the Pea Aphid Acyrthosiphon pisum Less Attractive to the Parasitoid Aphidius ervi

Autor: Mohannad Ismail, Penelope Zanolli, Frédéric Muratori, Thierry Hance

Publikováno v: Insects, Vol 12, Iss 10, p 878 (2021)

Herbivore-induced plant volatiles constitute the first indicators of insect host presence, and these can affect the foraging behavior of their natural enemies. The density of insect hosts may affect the nature and concentration of these plant-induced
