Root‐Inspired Microneedle Patch With Interlocked Rigid‐Soft Architecture for High Tissue‐Adaptiveness

Advanced Science, EarlyView.
A root‐inspired microneedle array patch uses lattice‐based mechanical interlocking to unite rigid microneedles with a flexible substrate. The interlocked rigid–soft architecture improves interfacial bonding, supports stable adhesion on curved and wet tissues under dynamic motion, and provides a versatile platform for robust biointerfacing and future ...

Contrasting aerial moose population estimation methods and evaluating sightability in west‐central Alberta, Canada

Wildlife Society Bulletin, 2014
Population assessment is a primary component of ungulate management, but managers are continuously under pressure to reduce survey cost. Another concern in aerial surveys is accounting for undetected animals (i.e., visibility bias).

Status Review of Guinayangan Quezon Mangrove Forest: An Assessment of Species Diversity and Habitat Analysis [PDF]

E3S Web of Conferences
This study was conducted to determine the status of the Mangrove Walk located in Brgy. Calimpak, Guinayangan, Quezon. Three main procedures were undertaken: species identification; habitat analysis using percent crown cover, regeneration per m², and ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Surveying abundance and stand type associations of Formica aquilonia and F. lugubris (Hymenoptera: Formicidae) nest mounds over an extensive area: Trialing a novel method

European Journal of Entomology, 2012
Red wood ants are ecologically important members of woodland communities, and some species are of conservation concern. They occur commonly only in certain habitats in Britain, but there is limited knowledge of their numbers and distribution.

Prey selection and food habits of the Tiger Panthera tigris (Mammalia: Carnivora: Felidae) in Kalakkad-Mundanthurai Tiger Reserve, southern Western Ghats, India

Journal of Threatened Taxa, 2020
The Endangered Tiger Panthera tigris is the largest felid, distributed over 1.1 million km2 globally.  Conservation of Tigers largely depends on the preservation of its natural prey base and habitats.

Hemiparasitic Castilleja presence is correlated with increased plant biodiversity across montane plant communities

American Journal of Botany, EarlyView.
Abstract Premise Root hemiparasites form haustoria in belowground roots of hosts to extract nutrients and water from the surrounding hosts. Through parasitic symbiosis, these plants disproportionately affect plant communities relative to their abundance by reducing host size, altering nutrient flow, and eventually increasing local biodiversity.

Line-transect data may not produce reliable estimates of interannual sex-ratio and age structure variation in West African savannah ungulates

Tropical Zoology, 2020
Adult sex ratios and age structures are important wildlife population parameters, but they have been poorly investigated in ungulate species in West African savannahs.

Complications and Clinical Outcomes Following Modified Endoscopic Denker's With Pyriform Aperture Preservation: A Prospective Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The modified endoscopic Denker's (MED) approach provides access to all maxillary sinus (MS) walls for resection of various MS and retromaxillary pathologies, but the anteromedial maxilla has historically been resected. This study determined complication rates and outcomes following MED with pyriform aperture (PA) preservation ...

Regional gas exchange evaluation during ex vivo lung perfusion in a swine model of localized lung dysfunction

Animal Models and Experimental Medicine, EarlyView.
Abstract Background Ex vivo lung perfusion (EVLP) allows the evaluation of lungs that do not meet standard transplantation criteria. Current procedures do not permit the identification of regional functional deficits. We investigated the feasibility of assessing lobar gas exchange during EVLP in a swine model.
