An In-Class Role-Playing Activity to Foster Discussion and Deeper Understanding of Biodiversity and Ecological Webs [PDF]

, 2013
In a general sense, biodiversity is an intuitively simple concept, referring to the variety of Earth’s organisms. Ecologists, however, conceptualize biodiversity in a more nuanced, multidimensional way to reflect the enormous diversity of species, niches,

Qualitative geographical variation in interspecific interactions

Ecography, 2004
We explore geographical variation in the density relationship between potential competitor forest bird groups, resident Parus spp. and migrant Fringilla spp., across Europe using published bird census results.

Profiling Localized Immunomodulation and Drug Biodistribution within a Subcutaneous Vascularized Niche for Cell Transplantation

Advanced Science, EarlyView.
We studied how five common immunosuppressants behave when delivered directly to a transplant site instead of systemically. Using a vascularized implant for islet transplantation, we show that local delivery protects grafts, limits drug spread to the rest of the body, and produces distinct immune signatures.

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

Advanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

Interspecies Haptic Sociality: An Observation of Grooming Between Two Mongoose Species

Ecology and Evolution
Meerkats (Suricata suricatta) and yellow mongooses (Cynictis penicillata) share many behavioural characteristics and are known to, on rare occasions, live in close association through displayed cooperative vigilance and shared burrow use.

Interactions between species introduce spurious associations in microbiome studies

, 2018
Microbiota contribute to many dimensions of host phenotype, including disease. To link specific microbes to specific phenotypes, microbiome-wide association studies compare microbial abundances between two groups of samples.

Intrinsic competition and its effects on the survival and development of three species of endoparasitoid wasps [PDF]

, 2009
In natural systems, pre-adult stages of some insect herbivores are known to be attacked by several species of parasitoids. Under certain conditions, hosts may be simultaneously parasitized by more than one parasitoid species (= multiparasitism), even ...

Plant Genetic Engineering: Technological Pathways, Application Scenarios, and Future Directions

Advanced Science, EarlyView.
This review maps the fast‐evolving landscape of plant genetic engineering, linking enabling platforms with trait‐focused applications in architecture optimization, stress resilience, yield improvement, and quality enhancement. It highlights how genome editing, transgenic strategies, and emerging multi‐gene approaches reshape breeding pipelines, while ...

Predation risk reduces a female preference for heterospecific males in the green swordtail [PDF]

, 2016
The presence of a predator can result in the alteration, loss or reversal of a mating preference. Under predation risk, females often change their initial preference for conspicuous males, favouring less flashy males to reduce the risk of being detected ...

Development‐based In Vivo Bioreactor Strategy for Challenging Senescent Bone Reconstruction

Advanced Science, EarlyView.
We present a development‐based in vivo bioreactor strategy to generate rejuvenated bone grafts (vBR‐Bone) within aged hosts. By enclosing vBR‐Bone fragments within an asymmetric biomimetic periosteum, segmental femoral defects in aged mice were successfully repaired within 6 weeks. Mechanistically, the multifactors of vBR‐Bone reconstitute a remodeling
