It's all about food: Environmental factors cause species‐specific dispersal
Ecosphere, 2022 Dispersal is a vital component of the life history of nearly all organisms. The ability to disperse determines the distribution and abundance of a species and thus its community dynamic at different sites.

Predators weaken prey intraspecific competition through phenotypic selection
Ecology Letters, 2020 Abstract Predators have a key role shaping competitor dynamics in food webs. Perhaps the most obvious way this occurs is when predators reduce competitor densities. However, consumption could also generate phenotypic selection on prey that determines the strength of competition, thus coupling consumptive and trait‐based effects of ...

The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Observations on the intraspecific variation in tadpole morphology in natural ponds
Acta Herpetologica, 2017 Intraspecific morphological variation of anuran tadpoles occurs in response to several factors. Causes and consequences of this variation have been largely studied hitherto in controlled environments, but data from natural habitats is clearly less ...

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes
The Anatomical Record, EarlyView.Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Predatory Functional Response of Harmonia sedecimnotata to Aphis craccivora
Guangdong nongye kexue【Objective】The study was conducted to clarify the predation capacity of Harmonia sedecimnotata on Aphis craccivora, with a view to providing a theoretical basis for field control of A. craccivora by H. sedecimnotata.【Method】H.

Trade-offs between predation risk and growth benefits in the copepod Eurytemora affinis with contrasting pigmentation. [PDF]
PLoS ONE, 2013 Intraspecific variation in body pigmentation is an ecologically and evolutionary important trait; however, the pigmentation related trade-offs in marine zooplankton are poorly understood.

Predator cues reduce intraspecific trait variability in a marine dinoflagellate [PDF]
BMC Ecology, 2017 Phenotypic plasticity is commonplace and enables an organism to respond to variations in the environment. Plastic responses often modify a suite of traits and can be triggered by both abiotic and biotic changes. Here we analysed the plastic response towards a grazer of two genotypes of the marine dinoflagellate Alexandrium fundyense, evaluated the ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT Synthetic biology has recently proven to be a valuable tool for enhancing agriculture even in the face of environmental and biological stresses. Understanding the challenges that militate synthetic biology will assist in ensuring safe, stable, and scalable crop production.
