Item type:Publication, Ревитализација на опожарени шумски екосистеми преку природно обновување(Македонско еколошко друштво, 2013); ; ; Шумските екосистеми се еден од најзначајните столбови на растителниот и животинскиот биодиверзитет, но нивната стабилност и одржливост често пати е загрозувана од различни биотски, антропогени или абиотски фактори. Во одредени случаи настанува и до целосно уништување на одреден шумски екосистем. Во таквите случаи многу чест и многу сериозен причинител се шумските пожари, кои за кусо време опожаруваат големи шумски површини и значително го нарушуваат или целосно уништуваат шумскиот екосистем. Сепак, способноста за природно обновување како карактеристика на шумската дендрофлора е значаен фактор за повторно воспоставување на шумска вегетација на опожарените шумски површини и целосна ревитализација на шумскиот екосистем. Целта на овој труд е да се утврдат основите природни сукцесивни процеси на шумската дрвенеста вегетација кои се појавуваат некоку години по силен шумски пожар од кој целосно е уништен шумскиот екосистем. Со проучувањето на појавата, развитокот, квалитативните и квантитативни карактеристики на единките од природната обнова се добиени податоци за можноста и успешноста на ревитализацијата на опожарениот шумски екосситем. За таа цел извршени се теренски истражувања преку директни мерења и проучувања на природната обнова со методот на пробни површини. Добиените резултати укажуваат на тоа дека опожарената шумска површина постепено се ревитализира, првенствено со пионерски видови од шумската дендрофлора, но за целосна ревитализација на шумскиот екосистем е потребен долг временски период. The forest ecosystems are one of the most important foundations of the biological diversity concerning flora and fauna, but forest’s natural balance and sustainability are often on impact and influence by wide spectra of biotic, anthropogenic or abiotic factors. In specific circumstances, some of the forest ecosystems can be totally destroyed. Namely, the wildfires, in particular forest fires can cause enormous consequences and devastating impact on forest ecosystems; for short period of time forest fires can burn large forest mass and make the forest ecosystem an erasure. Even so, the forest vegetation has a very important and essential ability- the dendrofloral capacity for natural regeneration, both vegetative and by seed, and for a period of time to re-establish and implicitly rehabilitate, i.e. to grew up and become a forest as it once was. The main purpose of this scientific paper is to determine and note the basic natural succession processes of the forest dynamics after forest fire, particularly the natural regeneration of the forest woody species. Thus, determination of the appearance, development, qualitative and quantitative characteristics of the individuals in a natural regeneration process were made and the data base was analyzed to see the possibility and efficiency of the rehabilitation of the burned forest ecosystem. Therefore, field examinations were made using direct measurements and research of the presence of the natural regeneration; the method of the sample plats was used. The results indicate that burned forest area gradually and progressively regenerates, primarily with pioneer species of the forest dendroflora. After all, for complete rehabilitation of the forest ecosystem there is a need of a long period of time; eventually, the forest regenerates slowly, but assuredly. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Abiotic factors impact on soil respiration(Institute of Lowland Forestry and Environment. Novi Sad, Serbia., 2025-12-05); ; Soil respiration describes the process of gas exchange between organisms and their environment. As one of the key processes in ecosystems, soil respiration is linked to ecosystem productivity, soil fertility, and the regional and global carbon cycles. The objective of this study is to investigate the impact of abiotic factors, particularly variations in air temperature and humidity, on the intensity of soil respiration in the dystric cambisols within the Quercetum montanum typicum forest community at the National Park “Fruška Gora” in the Vojvodina Province of Serbia. A total of 32 site visits were conducted in 2014–2017 period to obtain site-specific data on air and soil temperature and humidity, and soil evaporation and respiration. The key findings indicate that the variations in air temperature and humidity significantly impact soil respiration. In most cases, soil respiration positively correlates with soil temperature; however, in some years, a nonlinear response has been observed, which may indicate thermal stress at higher temperatures. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, EXPLOITING THE UNTAPPED POTENTIAL OF FRUIT TREE WILD DIVERSITY FOR SUSTAINABLE AGRICULTURE (FRUITDIV PROJECT)(Faculty of Agricultural Sciences and Food - Skopje, Ss. Cyril and Methodius University in Skopje, 2025-10-08); ; ; The domestication of fruit trees has resulted in a significant genetic bottleneck, limiting the resilience of modern cultivars to abiotic and biotic stresses driven by climate change. Crop Wild Relatives (CWR) of major pome (apple, pear) and stone (cherry, plum, etc.) fruits represent a critical, yet underutilized, reservoir of genetic diversity for traits like disease resistance and drought tolerance. The FRUITDIV project, a 5-year Horizon Europe initiative (2024-2028), aims to systematically monitor, characterize, use, and conserve the diversity of fruit tree CWR to enhance the sustainability and climate resilience of European fruit production. A multidisciplinary consortium of 27 partners from 14 countries employs an integrated approach across six core research work packages. This includes: (1) creating a comprehensive CWR inventory; (2) advanced genotypic and ex-situ phenotypic characterization; (3) developing multi-omics resources for data analysis and sharing; and (4) using these data to strategically introduce CWR alleles into pre-breeding programs. FRUITDIV will generate and make publicly available a suite of resources, including a detailed CWR knowledge base, genomic datasets, phenotyping data on valuable agronomic traits, and novel pre-breeding plant materials. The project will also deliver frameworks for the sustainable conservation and economic valuation of CWR genetic resources. By bridging the gap between conservation and breeding, FRUITDIV will unlock the genetic potential of wild fruit species. The project's outputs are designed to provide breeders and farmers with the tools and genetic material needed to develop robust fruit varieties, ensuring the long-term productivity and sustainability of European agriculture.
