Remote sensing (RS) has been widely used to assess the forest health status. Forest fragmentation has been recognized as a threat to the forest as it causes loss of biodiversity. The study of forest fragmentation is important for the conservative approach to forest area. In recent years, the urban forest has witnessed forest fragmentation. The present study focused on the assessment of vegetation cover and forest fragmentation using multi-temporal satellite data (1991, 2001, 2011, and 2021). Landscape Fragmentation Tool v2.0 (LFT v2.0) was used to analyze forest fragmentation in the urban forest of Delhi: Sanjay Van and Southern Ridge by assigning an edge width of 100 m. LFT v2.0 categorizes forest fragmentation into four class categories: patch, perforated, edge, and core classes. It was found that vegetation cover in Sanjay Van has decreased by 1.96%, whereas the area under vegetation covered in the Southern Ridge increased by 4.62% in the last decade. The assessment of forest fragmentation found that patch forests have increased and declined in core forest areas. These changes suggested a high disturbance due to anthropogenic activities leading to the degradation of the forest's health. The finding of the study helps in the identification of sensitive areas which require immediate conservation measures for the reclamation and restoration of degraded forest areas. With proper management, plans, and policies, continuous, intact, and healthy forests can be restored to maintain ecosystem integrity and thereby regulate all ecosystem services efficiently.

Human-caused conversion of natural habitat areas to developed land cover represents a major driver of habitat loss and fragmentation, leading to reorganization of biological communities. Although protected areas and urban greenspaces can preserve natural systems in fragmented landscapes, their efficacy has been stymied by the complexity and scale-dependency underlying biological communities. While migratory bird communities are easy to-study and particularly responsive to anthropogenic habitat alterations, prior studies have documented substantial variation in habitat sensitivity across species and migratory groups.

Background: Currently, traditional blood biomarkers such as neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA) etc. are mostly elevated in the late stage of tumour, and patients have already lost the chance of tumour eradication when the relevant indexes are found to be elevated. Therefore, there is a need for blood biomarkers with higher sensitivity, better specificity, and better accessibility.

These species face significant threats from habitat loss and fragmentation, leading to a decline in biodiversity. To mitigate these threats, the Maxent algorithm was employed to analyze current and future distribution patterns, with a particular focus on the influence of climate variables in predicting potential distribution shifts and assessing extinction risks under the optimistic SSP1-2.

Purpose: This systematic review aimed to identify and compare tools used to evaluate quality of life (QoL) after pelvic radiation for cervical cancer and to describe variations in results within commonly used instruments. This review hypothesized regional preferences in the selection of these tools and an absence of uniformity in their application globally.
Methods And Materials: A comprehensive search of 6 databases was conducted between the inception of each included database and June 14, 2023, focusing on studies evaluating the QoL of patients with cervical cancer during and after radiation.

Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.
