Coevolution and Functional Effects of Endosymbiotic Rickettsia in Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) Across China

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.

Crescimento de Eucalyptus urophylla em Meio Hidropônico com Diferentes Proporções de Nitrato e Amônio [PDF]

Floresta e Ambiente, 2014
Este estudo teve como objetivo avaliar respostas fisiológicas e crescimento de plantas jovens de Eucalyptus urophylla em meio hidropônico, num delineamento experimental inteiramente casualizado, com cinco proporções de NO3- e NH4+ (0/100, 25/75, 50/50, 75/25 e 100/0) e quatro repetições. As proporções NO3-/NH4+ afetaram o crescimento inicial, alterando

Effects of eucalyptus thinning on soil chemical attributes in an unfertilized silvopastoral system 6 years after thinning

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Tree thinning is a common practice in silvopastoral systems, but there is no standard percentage of thinning used by farmers. Moreover, it is unclear how the percentage of thinning affects soil chemical attributes throughout the soil profile and throughout the transect between eucalyptus lines.

Chrysoporthe cubensis‐Induced Wilting in Eucalypt Mini‐Stumps: In Vitro Fungus and Disease Development

Journal of Phytopathology, Volume 174, Issue 1, January/February 2026.
ABSTRACT Chrysoporthe cubensis was reported to cause wilting that later progressed to dieback and death in eucalypt mini‐stumps. This study aimed to evaluate the influence of various factors on the in vitro development of C. cubensis and to reproduce the wilting symptoms in eucalypt following artificial inoculation. Conidial production by C.
