Effects of mosquitofish (Gambusia affinis) cues on wood frog (Lithobates sylvaticus) tadpole activity

open access: yesActa Herpetologica, 2011
We examined the changes in activity of wood frog (Lithobates sylvaticus) tadpoles exposed to combinations of visual, chemical, and mechanical cues of the invasive mosquitofish (Gambusia affinis).

Perch, Perca fluviatilis show a directional preference for, but do not increase attacks toward, prey in response to water-borne cortisol [PDF]

open access: yesPeerJ, 2017
In freshwater environments, chemosensory cues play an important role in predator-prey interactions. Prey use a variety of chemosensory cues to detect and avoid predators.

Color, Bacteria, and Mosquito Eggs as Ovipositional Attractants for \u3ci\u3eAedes Aegypti\u3c/i\u3e and \u3ci\u3eAedes Albopictus\u3c/i\u3e (Diptera: Culicidae) [PDF]

open access: yes, 2018
Selected bacterial washes, color, and mosquito eggs were comparatively examined as ovipositional attractants for Aedes aegypti and Aedes albopictus. Any evidence of additive activity was noted.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Non‐Consumptive Effects of Cannibalism Elicit a Metabolic Response in Dragonfly Larvae

open access: yesEcology and Evolution
Predator–prey interactions typically involve changes in metabolic rates associated with hunting, foraging, and activation/maintenance of defense mechanisms. Similar response can result from non‐consumptive effects mediated by chemical cues, such as alarm

Hatching Strategies in Monogenean (Platyhelminth) Parasites that Facilitate Host Infection [PDF]

open access: yes, 2011
In parasites, environmental cues may influence hatching of eggs and enhance the success of infections. The two major endoparasitic groups of parasitic platyhelminths, cestodes (tapeworms) and digeneans (flukes), typically have high fecundity, infect more

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

open access: yesFEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]

open access: yes, 2016
How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

The role of the male produced pheromone in the reproduction behaviour of the southern armyworm Pseudaletia separata (Wlk.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology. [PDF]

open access: yes, 1971
Detailed courtship patterns have been described for few species of Lepidoptera. Most of the descriptive work in the literature is fragmentary or lacking in experimental or statistical analysis.
