Background: True date palms (Phoenix dactylifera L.) are impressive trees and have served as an indispensable source of food for mankind in tropical and subtropical countries for centuries. The aim of this study is to differentiate date palm tree varieties by analysing leaflet cross sections with technical/optical methods and artificial neural networks (ANN).
Results: Fluorescence microscopy images of leaflet cross sections have been taken from a set of five date palm tree cultivars (Hewlat al Jouf, Khlas, Nabot Soltan, Shishi, Um Raheem). After features extraction from images, the obtained data have been fed in a multilayer perceptron ANN with backpropagation learning algorithm.
Conclusions: Overall, an accurate result in prediction and differentiation of date palm tree cultivars was achieved with average prediction in tenfold cross-validation is 89.1% and reached 100% in one of the best ANN.

CRISPR ribonucleoprotein (RNP)-mediated genome editing offers a transgene-free platform for precise genetic modification in diverse herbaceous and tree species, including rice, wheat, apple, poplar, oil palm, rubber tree and grapevine. However, its application in woody plants faces distinct challenges, notably inefficient delivery and regeneration difficulties, particularly in species such as bamboo. While some of these issues also occur in herbaceous plants, they are often significantly more complex in woody species due to factors such as intricate cell wall architecture, widespread recalcitrant genotypes and inherent limitations of current delivery platforms.

This study was conducted during the 2024 growing season at the Palm Research Station in Al-Zafaraniya, Baghdad, Iraq. A total of 54 uniform date palm trees (Khastawi and Khadhrawi cultivars), approximately 15 years old and planted at 10-m spacing, were selected for experimental treatments. The objective was to evaluate the effects of three concentrations of nano NPK fertilizer (0, 2, and 4 g·L), applied in six foliar doses, and three concentrations of potassium silicate (0, 2, and 4 mL·L), applied in four foliar doses, as well as their interaction, on date yield, and fruit quality.

To investigate the phylogenetic relationship between two species of squirrels, the hoary-bellied Himalayan squirrel Callosciurus pygerythrus and five-striped palm squirrel Funambulus pennantii, at the population level to assist conservation and management, we analysed partial mitochondrial cytochrome b gene sequences (1140 base pairs). The hoary-bellied Himalayan squirrels were collected from the Chittagong University campus and the Hazarikhil Wildlife Sanctuary, Chattogram, and the five-striped palm squirrels were collected from the Rajshahi Zoo area of Bangladesh. Blood samples were collected from anaesthetized squirrels by expert veterinarians, drawing blood from femoral veins in accordance with proper protocols and permission from respective authorities for the PCR (polymerase chain reaction) study.

The greater noctule () is a threatened tree-roosting bat species with a fragmented distribution, possibly due to limited roosting habitat. Deforestation, tree disease and climate change are reducing forest and roost availability. Effective conservation action and forest management require detailed knowledge of the bats' roosting behaviour and requirements, which is lacking for this species, particularly in southern European forests.
