Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for a deeper understanding of the effects of natural processes and human behaviour/activities on environment and the anthropogenic impact of economic development on ecosystems.</p> https://www.lmaleidykla.lt/ojs/index.php/biologija/article/view/6743 2026-01-14T09:55:38+02:00 Lietuvos mokslų akademija ojs@lmaleidyba.lt

<p>Upon the&nbsp;first discovery, this publication provides the&nbsp;results of the&nbsp;examination and documentation of the&nbsp;female genitalia of Dvidulopsis Stonis &amp; Diškus, an endemic Neotropical genus previously known only from male specimens. It also describes Stigmella mariusi Stonis &amp; Diškus, sp.&nbsp;nov., a&nbsp;previously overlooked Acalypha-feeding species of Nepticulidae from the&nbsp;western premontane Amazon.</p>

<p>This study evaluated four landraces of local dill (Anethum graveolens) from Ardabil, Moghan, Mashhad, and Kerman, with the&nbsp;objective of assessing genetic and phytochemical variabilities. Plants were cultivated under field conditions on loamy soil and harvested at full flowering, the&nbsp;stage associated with maximum production of essential oil. Essential oils were extracted from leaves and flowers using low-temperature oven drying (40°C) and assessed via gas chromatography-mass spectrometry for measuring major constituents, including carvone, limonene, α-phellandrene, myristicin, dill ether, and dillapiole. Genotype × trait biplot analysis explained 82% of the&nbsp;total variation, and positive associations were observed between myristicin and dill ether, as well as between α-terpinene and α-pinene, while negative correlations were found between these compounds and α-terpinolene, dibutyl phthalate, and other minor constituents. Trait discrimination and representativeness analyses identified β-pinene and sabinene as the&nbsp;most informative for differentiating genotypes, followed by 1-terpineol, 5-hydroxymethylfurfural, and 5-epi-neointermedeol. Although highly abundant, such traits as essential oil, carvone, and limonene exhibited low discriminative potential. Among genotypes, Moghan displayed the&nbsp;highest essential oil, D-carvone, and l-limonene content, consistent with a&nbsp;seed-type chemotype dominated by carvone and limonene. Ardabil was rich in myristicin, dill ether, and α-phellandrene, representing a&nbsp;herb-type chemotype. Mashhad emerged as the&nbsp;most favourable genotype overall, combining desirable essential oil yield with moderate stability, while Kerman exhibited a&nbsp;high and stable dillapiole content, making it suitable for applications requiring consistent essential oil quality.</p>
