Based on the results obtained, the study aims to propose strategic directions for enhancing innovation activities in the sector. To fulfill this objective, the analysis relies on data collected through a survey conducted between 2023 and 2024, involving a representative sample of 107 agri-food enterprises.The cause-effect relationship between innovation barriers and unrealized potential profit was estimated using the ridge regression method. The results indicate that high innovation costs and limited internal financial resources have a substantial impact on enterprise performance. A moderate influence is associated with factors such as the shortage of qualified personnel, difficulties in securing external funding, export restrictions, sales prohibitions related to the accumulation of state reserves, and obstacles in forming partnerships for innovation-related initiatives. Conversely, barriers such as weak market demand for innovative products, limited access to innovation-related information, and low employee motivation to engage in innovation activities were found to have minimal impact. The findings of the research served as a basis for proposing measures to reduce the influence of innovation barriers, differentiated according to their nature: endogenous and exogenous. 2025-01-01T00:00:00Z https://repository.utm.md/handle/5014/36291 Epipactis leptochila (Godfery) Godfery (Orchidaceae) - specie nouă pentru flora Republicii Moldova SFECLĂ, Victor; SFECLĂ, Irina; GHENDOV, Veaceslav Studiile privind răspândirea și condițiile ecologice ale cenozelor de plante rare sunt necesare în dezvoltarea principiilor pentru protejarea acestora. Actualmente este cunoscut arealul pentru majoritatea speciilor rare din flora Europei de Est. Totodată, pentru multe dintre acestea sunt necesare studii aprofundate privind corologia, atât la nivel regional, cât și local. În această lucrare este raportată și descrisă o specie nouă, nerelatată anterior pentru flora vasculară a Republicii Moldova, și anume Epipactis leptochila (Godfery) Godfery. În cadrul rezervației peisagistice „Dobrușa” este răspândită la altitudini de 240-280 m, în arborete de amestec în care predomină stejarul pedunculat, frasinul și carpenul. Cercetările au vizat evidențierea caracterelor morfologice distinctive și particularitățile corologice, habitatul, ecologia, perioada de înflorire și efectivul populațiilor de E. leptochila. Datorită distribuției limitate, se sugerează necesitatea includerii speciei E. leptochila în cea de-a IV-a ediție a Cărții Roșii a Republicii Moldova atribuindu-i-se categoria de raritate - Critic periclitată (CR). 2023-01-01T00:00:00Z https://repository.utm.md/handle/5014/36290 Natural Variability Dominates Precipitation Variability over the Past 800 Years in Eastern Europe ROIBU, Cătălin-Constantin; NAGAVCIUC, Viorica; PALAGHIANU, Ciprian; MURSA, Andrei; ANDRIESCU, Cosmin-Mihai; COTOS, Mihai-Gabriel; ȘTIRBU, Marian-Ionuț; WAZNY, Tomasz; SFECLĂ, Victor; IONITA, Monica Tree ring chronologies are frequently used to gain invaluable insights into past climate variability. In this study, we developed a unique 804-yr oak ring width chronology network from eastern Europe to reconstruct annual hydroclimate variability with a particular focus on the 12 July month standardized precipitation index (SPI). The SPI reconstruction captures pronounced interannual-to-multidecadal fluctuations in moisture availability, revealing sequences of persistent droughts and pluvials. These reconstructed hydroclimatic extremes align with documented historical episodes of agricultural failure, famine, and population displacement, underscoring the SPI’s potential for identifying long-term climate–society linkages. Here, we show that the hydroclimate in the eastern part of Europe has largely remained stationary from 1221 to 2019, despite exhibiting substantial variability across interannual-to-multidecadal time scales. Wet years correspond to negative geopotential height anomalies over eastern Europe, promoting cyclonic flow and rainfall, while dry years align with persistent high pressure systems that suppress precipitation and shift storm tracks northward. These circulation anomalies cooccur with coherent Atlantic sea surface temperature (SST) patterns, warm subtropical and tropical anomalies during wet years, and cold anomalies during dry years, highlighting the coupled role of blocking and ocean variability in shaping multiyear droughts and floods across eastern Europe. Comparison with bias-corrected regional climate simulations suggests little change in mean annual hydroclimate through the twenty-first century, but a broadening range of possible outcomes increases risks of persistent extremes. Our study combines tree-ring reconstructions with documentary archives to place recent and future hydroclimatic extremes in a long-term context, offering critical insights for water management, agriculture, and forestry. 2026-01-01T00:00:00Z https://repository.utm.md/handle/5014/36289 Floristic notes from Bessarabia No. 241-276 PINZARU, Pavel; SFECLĂ, Victor; CANTEMIR, Valentina The paper presents new growing stations for 36 species of rare vascular plants from the spontaneous flora of the Republic of Moldova, highlighted as the result of the new floristic investigations carried out from the spring to the summer of the current year. The species Valerianella eriocarpa Desv. was recorded for the first time in the local flora, the presence of 7 rare species, little known previously, was confirmed and they were proposed to be included in the List of protected species and in The Red Book of the Republic of Moldova, 4th edition: Carex pseudocyperus L., C. strigosa Huds., C. vesicaria L., Epipactis leptochila (Godfery) Godfery, Fraxinus coriariifolia Scheele, Linum catharticum L. Senecio macrophyllus M.Bieb., and for the species Klasea bulgarica (Acht. & Stoj.) Holub, indicated only for one station in Batır commune, Cimislia district, from where it disappeared, another station was registered in the same locality.; În lucrare sunt prezentate noi stațiuni de creștere pentru 36 specii de plante vasculare rare din flora spontana a Republicii Moldova, evidențiate ca rezultat al noilor investigații floristice din primavara – vara anului curent. Specia Valerianella eriocarpa Desv. este ˆınregistrata prima data în flora locala, a fost confirmată prezența a 7 specii rare, puțin cunoscute anterior și se propun a fi incluse în Lista speciilor ocrotite și în Cartea Roșie a Republicii Moldova, ediția a 4-a: Carex pseudocyperus L., C. strigosa Huds., C. vesicaria L., Epipactis leptochila (Godfery) Godfery, Fraxinus coriariifolia Scheele, Linum catharticum L. Senecio macrophyllus M.Bieb., iar pentru specia Klasea bulgarica (Acht. & Stoj.) Holub, indicata numai pentru o singură stațiune din comuna ˘ Batîr, raionul Cimișlia, de unde a disparut, a fost înregistrată o altă stațiune în aceeași localitate. 2024-01-01T00:00:00Z
