Competitive E?ects of Vertical Integration with Downstream Oligopsony and Oligopoly [PDF]

open access: yes, 2009
We analyze the competitive e?ects of backward vertical integration by a partially vertically integrated ?rm that competes with non-integrated ?rms both upstream and downstream.

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

open access: yesNew Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.

Quasi-integration in less-than-truckload trucking [PDF]

open access: yes
This work studies the organization of less-than-truckload trucking from a contractual point of view. We show that the huge number of owner-operators working in the industry hides a much less fragmented reality.

Restored wetlands: interplay between environmental variables, aboveground and belowground plant traits, and carbon cycling

open access: yesNew Phytologist, Volume 252, Issue 1, Page 131-144, October 2026.
Assessing relationships between environmental conditions, aboveground and belowground plant traits, and carbon cycling in restored wetlands (grazed and ungrazed), compared to a baseline in near‐natural wetlands in Denmark, revealed that ecosystem functions can be restored, even in cases where plant biodiversity has not recovered.

Strategic vertical integration without foreclosure [PDF]

open access: yes
We determine the endogenous degree of vertical integration in a model of successive oligopoly that captures both efficiency gains and strategic effects.

Mutual antagonism between auxin and diacylglycerol acyltransferase 2 regulates high‐temperature‐induced hypocotyl elongation

open access: yesNew Phytologist, Volume 252, Issue 1, Page 222-240, October 2026.
Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...

Estructura y composición florística de la vegetación secundaria en tres regiones de la sierra norte de Chiapas, México

open access: yesPolibotánica, 2015
El estado de Chiapas presenta una severa deforestación de los diferentes tipos de selvas, en la actualidad sólo quedan fragmentos de la vegetación original y con diferentes grados de sucesión, por lo que se planteó el objetivo de conocer la estructura y ...

Differential responses of fungal guilds to climatic effects mediated by changes in dominant vegetation

open access: yesNew Phytologist, Volume 252, Issue 2, Page 861-874, October 2026.
Sampling design and locations in Europe from the southernmost to the northernmost location: Taygetos (Greece), Manchoya (Spain), Cvrsnica (BIH), Comborsier (France), Krn (Slovenia), Dachstein (Austria), Malá Fatra (Slovakia), Jondal (Norway). Summary Climate is a major driver of fungal species distributions and community composition, yet disentangling ...

Selection shapes the evolution of genome size in a globally invasive plant

open access: yesNew Phytologist, Volume 252, Issue 2, Page 875-891, October 2026.
Abundance, genomic distribution and structural characteristics of transposable elements (TEs) and ribosomal RNA (rRNA) genes across the common ragweed (Ambrosia artemisiifolia L.) reference genome. Summary Biological invasions provide powerful natural experiments for understanding how genome architecture responds to novel climatic environments ...
