https://lnkd.in/dqV5V89v Very interesting! IMPLICATIONS FOR MANAGEMENT OF INVASIVE PLANTS Biological control #biocontrol of #invasiveplants via introduction of host-specific insects is one of the major approaches against invaders worldwide (Müller-Schärer et al. 2018; Schwarzländer et al. 2018). Invasive plants, such as A. artemisiifolia could trade-off between resistance to insects and tolerance to abiotic stresses, providing new insights into biological control (Müller-Schärer et al. 2014; Sun et al. 2022). Introduction of specialist insects from the native ranges enables invasive plants and their co-evolved enemies to reassociate, likely enhancing plant defense against insects. However, such reassociation may also result in an evolutionary decrease in abiotic stress tolerance and thus likely reduces their competitive ability compared with indigenous species. Together with the direct effects of insect damage on plant growth and reproduction, these accompanying effects on responses to abiotic stresses could enhance the efficacy of biocontrol over time (Xiao et al. 2019). Thus, simultaneously considering responses to both biotic and abiotic stress are necessary when in assessing the long-term effects of classical biological control programs.

Spittlebugs: Nature’s Foam-Producing Pest  Did you know that spittlebugs, tiny insects under the Aphrophridae family, have a significant impact on agriculture and ecosystems? These fascinating creatures are not only major pests of sugarcane and forage grasses but also play a role in C4 photosynthesis and nitrogen fixation.  One of their most interesting features is their foamy covering, which acts as a thermoregulatory mechanism. This unique material has potential applications in biomimetics and biomedical research.While spittlebugs may be considered pests, they are a testament to the incredible diversity and complexity of the natural world. #spittlebugs  #entomology #biomimicry #agriculture

Fungal colany morphs 🍄 Fungal contaminations are the most common types of contamination on growth media. Among the contaminations I have observed, one particular colony stands out due to its distinct morphology. Unlike the others, this colony exhibits a well-defined circular ring-like pattern. Due to the higher nutrient concentration in the medium compared to standard PDA or NA, this fungus forms only hyphae without developing spore-forming structures, making it challenging to identify the species or even classify it to the genus level. #nature #fungi #selflearning #ravie #contamination

Phylogenetic Analysis of Some Wild Birds in Şanlıurfa (Türkiye) Authors: Arif Parmaksız, Adil Uztemur, Cahit Çeçen Abstract: The increase in population worldwide causes an increase in anthropogenic effects such as agriculture and industry, and as a result, the habitat of many naturally living species is changing. Because of this change, species that adapt to the environment survive and those that cannot adapt to the environment either had to migrate in order to survive, or their numbers decreased and their generations were endangered. In Şanlıurfa, both the construction of dams and the increase in agricultural activities significantly affect bird diversity. Therefore, it is important to take precautions by investigating their phylogenetic origins and migration routes. The aim of the present study is to perform phylogenetic analysis using mtDNA COI marker for some wild bird species in Şanlıurfa. Muscle tissue was taken from nine wild bird species, DNA isolation was performed using a commercial kit, and the target gene region was amplified by using PCR method. The genetic structure of the species was determined by sequence analysis of the obtained target PCR products and a phylogenetic tree was drawn. The results were evaluated at haplotype level by comparing with the sequences in the gene bank. It was determined that the haplotypes determined for Tyto alba, Ciconia ciconia, and Elanus caeruleus species were new and not found in other countries.

Characterizing species similarity is crucial for generalizing and transferring knowledge effectively. *A rigorous comparison between species should consider different aspects, such as physiological characteristics, morphology, metabolism, ecology, and behaviour, giving special importance to criteria that can be assessed objectively. *𝐼𝑛 𝑡ℎ𝑖𝑠 𝑠𝑡𝑢𝑑𝑦, 𝑡ℎ𝑒 𝑟𝑒𝑙𝑎𝑡𝑖𝑜𝑛𝑠ℎ𝑖𝑝 𝑜𝑓 𝑠𝑖𝑚𝑖𝑙𝑎𝑟𝑖𝑡𝑦 𝑏𝑒𝑡𝑤𝑒𝑒𝑛 𝑐𝑜𝑚𝑚𝑒𝑟𝑐𝑖𝑎𝑙 𝑠𝑝𝑒𝑐𝑖𝑒𝑠 (𝐴𝑡𝑙𝑎𝑛𝑡𝑖𝑐 𝑠𝑎𝑙𝑚𝑜𝑛 (𝑆𝑎𝑙𝑚𝑜 𝑠𝑎𝑙𝑎𝑟), 𝑔𝑖𝑙𝑡ℎ𝑒𝑎𝑑 𝑠𝑒𝑎𝑏𝑟𝑒𝑎𝑚 (𝑆𝑝𝑎𝑟𝑢𝑠 𝑎𝑢𝑟𝑎𝑡𝑎), 𝐸𝑢𝑟𝑜𝑝𝑒𝑎𝑛 𝑠𝑒𝑎𝑏𝑎𝑠𝑠 (𝐷𝑖𝑐𝑒𝑛𝑡𝑟𝑎𝑟𝑐ℎ𝑢𝑠 𝑙𝑎𝑏𝑟𝑎𝑥), 𝑁𝑖𝑙𝑒 𝑡𝑖𝑙𝑎𝑝𝑖𝑎 (𝑂𝑟𝑒𝑜𝑐ℎ𝑟𝑜𝑚𝑖𝑠 𝑛𝑖𝑙𝑜𝑡𝑖𝑐𝑢𝑠), 𝑟𝑎𝑖𝑛𝑏𝑜𝑤 𝑡𝑟𝑜𝑢𝑡 (𝑂𝑛𝑐𝑜𝑟ℎ𝑦𝑛𝑐ℎ𝑢𝑠 𝑚𝑦𝑘𝑖𝑠𝑠), 𝑡𝑢𝑟𝑏𝑜𝑡 (𝑆𝑐𝑜𝑝ℎ𝑡ℎ𝑎𝑙𝑚𝑢𝑠 𝑚𝑎𝑥𝑖𝑚𝑢𝑠) 𝑎𝑛𝑑 𝑆𝑒𝑛𝑒𝑔𝑎𝑙𝑒𝑠𝑒 𝑠𝑜𝑙𝑒 (𝑆𝑜𝑙𝑒𝑎 𝑠𝑒𝑛𝑒𝑔𝑎𝑙𝑒𝑛𝑠𝑖𝑠) 𝑖𝑛 𝑡𝑒𝑟𝑚𝑠 𝑜𝑓 𝑝𝑎𝑟𝑎𝑚𝑒𝑡𝑒𝑟𝑠 𝑎𝑛𝑑 𝑝𝑟𝑒𝑑𝑖𝑐𝑡𝑖𝑜𝑛𝑠 𝑜𝑓 𝑏𝑜𝑑𝑦 𝑐𝑜𝑚𝑝𝑜𝑠𝑖𝑡𝑖𝑜𝑛 𝑎𝑛𝑑 𝑔𝑟𝑜𝑤𝑡ℎ 𝑚𝑜𝑑𝑒𝑙𝑠 𝑤𝑎𝑠 𝑒𝑣𝑎𝑙𝑢𝑎𝑡𝑒𝑑. *Different models (e.g., isometric and allometric, in the case of body composition models) and calibration methods (e.g., least squares, Huber loss regression and quantile regression) were used. *Species were compared based on the distance between model parametrizations and between predictions. Results suggest that the similarities within salmonid species are strong. Despite having some differences in growth, European seabass and gilthead seabream also show similarities, especially in the early life stages. *Results also suggest the metabolic body weight exponents for energy and protein are likely to be species-specific, ranging from 0.60 to 0.90, which agrees with previous studies that challenge the theory of universal metabolic allometry. This study provides important insights about body composition and growth patterns of different species. *Finally, this research methodology can have a wide range of practical application for both aquaculture and fisheries industries by supporting more accurate data quality control, model calibration, synthetic data generation, and assessment of species similarity for effective resource management. https://lnkd.in/gTn6dQc7 #Fisheries #Aquaculture #Fish_nutrition #Regression_analysis #Metabolic_allometry #Energy_protein_flux_model
