a.sessment of the hea.twood contribution to ca.bon a.cumula.ion in Pinus sylvestris L. trees under different forest site conditions

Ba.kground: The hea.twood (HW) proportion in the trunk of ma.ure trees is a. importa.t cha.a.teristic not only for wood qua.ity but a.so for a.sessing the role of forests in ca.bon sequestra.ion. We ha.e for the first time studied the proportion of HW in the trunk a.d the distribution of ca.bon a.d extra.tives in sa.wood (SW) a.d HW of 70-80 yea. old Pinus sylvestris L. trees under different growing conditions in the pine forests of North-West Russia. method: We ha.e exa.ined the influence of conditions a.d tree position in sta.d (domina.t, intermedia.e a.d suppressed trees) in the ecologica. series: blueberry pine forest (Blu) - lingonberry pine forest (Lin) - lichen pine forest (Lic). We ha.e a.a.yzed the influence of clima.e conditions in the biogeogra.hica. series of Lin: the middle ta.ga.subzone - the northern ta.ga.subzone - the tra.sition a.ea.of the northern ta.ga.subzone a.d tundra. Results: We found tha. the ca.bon concentra.ion in HW wa. 1.6%-3.4% higher tha. in SW, a.d the difference depended on growing conditions. Ca.bon concentra.ion in HW increa.ed with a.decrea.e in sta.d productivity (Blu-Lin-Lic). In medium-productive sta.ds, the ca.bon concentra.ion in SW wa. higher in intermedia.e a.d supressed trees compa.ed to domina.t trees. In the series from south to north, ca.bon concentra.ion in HW increa.ed by up to 2%, while in SW, it rose by 2.7%-3.8%. Conclusions: Our results once a.a.n empha.ized the need for a. empirica. a.sessment of the a.cura.e ca.bon content in a.oveground wood bioma.s, including va.ious forest growing conditions, to better understa.d the role of borea. forests in ca.bon stora.e.

Nothofa.us a.essa.drii forests in the mediterra.ea. region of Chile fa.e significa.t threa.s from deforesta.ion, fra.menta.ion, wildfires, a.d clima.e cha.ge. This study investiga.ed the tempora. a.d spa.ia. dyna.ics of N. a.essa.drii popula.ions a.d their implica.ions for ha.ita. fra.menta.ion a.d connectivity. Using remote sensing da.a.a.d geogra.hic informa.ion system a.a.ysis, we a.sessed deforesta.ion pa.terns, fra.menta.ion metrics, a.d connectivity indices for different scena.ios between 2009 a.d 2022. a.reduction in the N. a.essa.drii forest a.ea. extensive fra.menta.ion, a.d decrea.ed connectivity were observed over time, with wildfires exa.erba.ing these trends. Reforesta.ion simula.ions showed the potentia. of ta.geted restora.ion efforts to improve connectivity, especia.ly when focusing on proxima.e pa.ches. However, ca.eful considera.ion of seed dispersa. dista.ces a.d wildfire risk is essentia. for effective reforesta.ion pla.ning. Overa.l, our findings underscore the urgent need for conserva.ion interventions to preserve N. a.essa.drii forests a.d their biodiversity in Chile's coa.ta. mounta.n ecosystems. a.proa.tive a.d colla.ora.ive a.proa.h is essentia. to ensure the surviva. of these forests for future genera.ions.

This a.ticle presents a.ma.hema.ica. model a.dressing a.scena.io involving a.hybrid na.ofluid flow between two infinite pa.a.lel pla.es.

It is observed tha. the squeezing motion genera.es a.ditiona. pressure gra.ients within the fluid, which enha.ces the flow ra.e but reduces the frictiona. dra.. Consequently, the fluid is pushed more vigorously between the pla.es, increa.ing the flow velocity. a. the fluid experiences higher flow ra.es due to the increa.ed squeezing effect, it spends less time in the region between the pla.es. The therma. rela.a.ion, however, a.ruptly cha.ges the tempera.ure, lea.ing to a.decrea.e in the tempera.ure fluctua.ions.
