Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Three‐Dimensional Architecture of Ectopic Epithelium and Vasculature in Ovarian Endometriosis Revealed by Tissue‐Clearing Imaging

Cell Proliferation, EarlyView.
Our study employed a modified tissue‐clearing method combined with deep imaging for 3D reconstruction of ovarian endometriosis (OEM) lesions, revealing its morphological polymorphism at tissue and cellular levels. Besides, vessels preferentially clustered around the ectopic epithelium, with their distribution pattern strongly linked to the location of ...

Balancing risk and opportunity: Nasute termite responses to predator and competitor chemical cues

Ecological Entomology, EarlyView.
Nasutitermes corniger discriminates between heterospecific chemical cues during foraging, showing non‐random resource selection based on predator and competitor information. Predator chemical cues consistently reduce food resource selection, indicating avoidance driven by perceived predation risk rather than direct encounters.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Park‐and‐multi‐loop with autonomous delivery robots in last‐mile logistics

International Transactions in Operational Research, EarlyView.
Abstract This paper deals with the park‐and‐multi‐loop routing problem, in the context of last‐mile logistics, in which a fleet of traditional vehicles equipped with several autonomous delivery robots leaves from a depot to service a set of customer requests.

Automatic MGA trajectory planning with a modified ant colony optimization algorithm

, 2009
This paper assesses the problem of designing multiple gravity assist (MGA) trajectories, including the sequence of planetary encounters. The problem is treated as planning and scheduling of events, such that the original mixed combinatorial-continuous ...

Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity

Journal of Applied Entomology, EarlyView.
ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...
