Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]

open access: yes, 2007
We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

Distributed House-Hunting in Ant Colonies

open access: yes, 2015
We introduce the study of the ant colony house-hunting problem from a distributed computing perspective. When an ant colony's nest becomes unsuitable due to size constraints or damage, the colony must relocate to a new nest.

Observations on the Interrelationships among Ants, Aphids, and Aphid Predators [PDF]

open access: yes, 2017
Excerpt: The literature concerning the interactions of these insect groups is as interesting as it is extensive. It has generally been accepted that the relationship between ants and aphids has been one of mutualism in which ants derive all or a large ...

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Larger Seeds are Dispersed Farther: the Long-Distance Seed Disperser ant Aphaenogaster famelica Prefers Larger Seeds

open access: yesSociobiology, 2015
Seed dispersal by ants (myrmecochory) is an important life phase in flowering herbs of temperate deciduous forests, and long dispersal is basically preferable in terms of plant fitness.

Army ants algorithm for rare event sampling of delocalized nonadiabatic transitions by trajectory surface hopping and the estimation of sampling errors by the bootstrap method [PDF]

open access: yes, 2004
The most widely used algorithm for Monte Carlo sampling of electronic transitions in trajectory surface hopping (TSH) calculations is the so-called anteater algorithm, which is inefficient for sampling low-probability nonadiabatic events.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Various chemical strategies to deceive ants in three Arhopala species (lepidoptera: Lycaenidae) exploiting Macaranga myrmecophytes. [PDF]

open access: yesPLoS ONE, 2015
Macaranga myrmecophytes (ant-plants) are generally well protected from herbivore attacks by their symbiotic ants (plant-ants). However, larvae of Arhopala (Lepidoptera: Lycaenidae) species survive and develop on specific Macaranga ant-plant species ...

Alkaptonuuriast põhjustatud aordiklapi kitsenemus, südame pärgarteri haigus, teisene osteoartroos ja nende kirurgiline ravi [PDF]

open access: yes, 2013
Alkaptonuuria on haruldane, progresseeruv ja pöördumatu geneetiline ainevahetushaigus. Klassikalise kliinilise triaadina esinevad selle korral homogentisiinhappe eritus uriiniga, sidekoe (eriti kõhrkoe) pigmentatsioon ning degeneratiivne liigesepõletik ...
