Energy cost and return for hunting in African wild dogs and cheetahs

Nature Communications, 2016
The long-distance hunting behaviour of African wild dogs is thought to be energetically costly. Here, Hubel et al. show that multiple opportunistic short-distance hunts and group feeding make African wild dogs in mixed woodland savannah energetically ...

Vertical extratification of phytophagous and predator mites (Acari) on Caryocar brasiliense (Caryocaraceae) tree canopies

Persian Journal of Acarology, 2021
The distribution of Caryocar brasiliense Camb. (Caryocaraceae) trees is wide in the Brazilian Cerrado biome and its fruits are used by humans for food and as the main income source of many communities.

Behavioural compatibility, not fear, best predicts the looking patterns of chacma baboons

Communications Biology
Animal vigilance is often investigated under a narrow set of scenarios, but this approach may overestimate its contribution to animal lives. A solution may be to sample all looking behaviours and investigate numerous competing hypotheses in a single ...

TREX1, a predator for treating MSI‐H tumors?

Molecular Oncology, EarlyView.
Immunotherapy benefits many patients; yet, some with MSI‐H tumors remain unresponsive despite their high immunogenicity. Xu et al. reveal that TREX1 enables immune evasion by degrading cytosolic DNA and suppressing cGAS–STING–IFN‐I signaling. TREX1 loss restores DNA sensing, increases CD8+ T and NK cell infiltration, and boosts antitumor immunity ...

Size matters: Natural experiments suggest the dear enemy effect is moderated by pack size in African wild dogs

Ecology and Evolution
Remote monitoring of communal marking sites, or latrines, provides a unique opportunity to observe undisturbed scent marking behaviour of African wild dogs (Lycaon pictus).

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Additive opportunistic capture explains group hunting benefits in African wild dogs

Nature Communications, 2016
African wild dogs hunt collaboratively over long distances in grassland plains. Hubel et al. use high-resolution GPS to show that in their remaining habitat of mixed woodland savannah, African wild dogs use multiple opportunistic short-distance hunts ...

Morphometry of the reproductive system of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera, Pentatomidae) when submitted to different temperatures [PDF]

Ciência Rural, 2020
: In order to manipulate the mass rearing of natural enemies, temperature variations can be used. The effects are widely studied for their survival and developmental duration; however, there is little information about their reproductive system in the ...

Predator and prey functional traits: understanding the adaptive machinery driving predator–prey interactions

F1000Research, 2017
Predator–prey relationships are a central component of community dynamics. Classic approaches have tried to understand and predict these relationships in terms of consumptive interactions between predator and prey species, but characterizing the ...
