Complex dynamics in coevolution models with ratio-dependent functional response

open access: yes, 2009
We explore the complex dynamical behavior of two simple predator-prey models of biological coevolution that on the ecological level account for interspecific and intraspecific competition, as well as adaptive foraging behavior.

Exercise Interventions in Children, Adolescents and Young Adults With Paediatric Bone Tumours—A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Bone tumours present significant challenges for affected patients, as multimodal therapy often leads to prolonged physical limitations. This is particularly critical during childhood and adolescence, as it can negatively impact physiological development and psychosocial resilience.

Dynamical Complexity in Some Ecological Models: Effects of Toxin Production by Phytoplankton

open access: yesNonlinear Analysis, 2007
We investigate dynamical complexities in two types of chaotic tri-trophic aquatic food-chain model systems representing a real situation in the marine environment.

Effects of globa l warming on insect natural enemies

open access: yes浙江大学学报. 农业与生命科学版, 2022
With climate change, global temperatures are expected to rise, posing a pervasive and growing threat to biodiversity and ecosystem stability. As ectotherms, insects are completely dependent on environmental temperature to grow, develop, and regulate ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The Issue Isn’t Which Model of Consumer Interference Is Right, but Which One Is Least Wrong

open access: yesFrontiers in Ecology and Evolution, 2022
Empirical observations and an analogy with the history of ballistics illuminate the ongoing debate about the default choice for types of functional responses, based on consumer interference.

Generalized Functional Additive Mixed Models

open access: yes, 2016
We propose a comprehensive framework for additive regression models for non-Gaussian functional responses, allowing for multiple (partially) nested or crossed functional random effects with flexible correlation structures for, e.g., spatial, temporal, or

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Different adaptation strategies of two citrus scion/rootstock combinations in response to drought stress [PDF]

open access: yes, 2017
Scion/rootstock interaction is important for plant development and for breeding programs. In this context, polyploid rootstocks presented several advantages, mainly in relation to biotic and abiotic stresses.
