An Enhanced Energy Efficiency Routing for WSN based on Elephant Herding and Swarm Optimization Approaches

TESEA, Transactions on Energy Systems and Engineering Applications
Energy utilization and inadequacy of sensor nodes are considered major drawbacks in wireless sensor networks (WSNs). This is because the sensor nodes use the battery for recharging energy.

Temporal Responses to Warming: Do Wild Herbivores Trade Off Heat, Predators, and Humans?

Integrative Zoology, EarlyView.
We untangled how summer temperature, predators, and humans influenced behavioral responses in two deer species. Both reduced their daily activity level in response to warming, yet only roe deer increased nocturnality to avoid heat. Conversely, fallow deer traded off heat avoidance with predator avoidance.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

Integrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

A Stochastic Approach to the Power Requirements of the Electric Vehicle Charging Infrastructure: The Case of Spain

Energies
Battery electric vehicles represent a technological pathway for reducing carbon emissions in personal road transport. However, for the widespread adoption of this type of vehicle, the user experience should be similar to that of combustion engine ...

Home ranges, feeding sites, and daily movement behavior of the highly threatened Livingstone's fruit bat revealed through GPS tracking

Conservation Science and Practice, EarlyView.
Livingstone's fruit bat GPS tracks during day‐ and nighttime on Anjouan, Comoros, identifying likely feeding sites. Abstract The highly threatened Livingstone's fruit bat, Pteropus livingstonii, is endemic to only two islands of the Union of the Comoros, a country with some of the highest deforestation rates worldwide.

Do camera light traps for moths provide similar data as conventional funnel light traps?

Insect Conservation and Diversity, EarlyView.
We recorded moths using a traditional collection method (funnel light traps, FLTs) and compared them with records made using automated camera light traps (CLTs). In direct comparison, the recorded moth species richness was similar, but the CLTs were able to leverage their advantages over longer periods of time and recorded more species.

Location of fueling stations and routing of zero‐emission well‐boats in the Norwegian aquaculture industry

International Transactions in Operational Research, EarlyView.
Abstract We study the problem of locating hydrogen fueling stations for zero‐emission aquaculture vessels in Norway and model the problem as a location‐routing problem, considering both the location of hydrogen fueling stations and the routing of aquaculture vessels.

An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

International Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...

A matheuristic for the traveling salesman problem with positional consistency constraints

International Transactions in Operational Research, EarlyView.
Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.
