Repetitive concussive brain injury (CBI) is associated with cognitive alterations and increased risk of neurodegenerative disease.To evaluate the temporal window during which concussed remains vulnerable to a second concussion, anesthetized mice were subjected either sham or single repetitive CBI (either 3, 5, 7 days apart) using clinically relevant model CBI. Cognitive, vestibular, sensorimotor function (balance coordination) evaluated, postmortem histological analyses performed detect...
Abstract Free‐living male song sparrows experience three annually repeating life history stages associated with differential expression of sex steroid‐dependent reproductive and aggressive behavior. In the breeding stage, they display behavior have elevated circulating testosterone levels. During molt, males show little or no aggression behavior, basal levels testosterone. non‐breeding high order to understand more fully neural regulation seasonal birds were collected during all stages,...

Abstract Traumatic brain injury (TBI) causes selective hippocampal cell death, which is believed to be associated with cognitive impairment observed both in clinical and experimental settings. Although neurotrophin administration has been tested as a strategy prevent death following TBI, the potential neuroprotective role of neurotrophin‐4/5 (NT‐4/5) TBI remains unknown. We hypothesized that NT‐4/5 would offer neuroprotection for selectively vulnerable neurons TBI. Measurements rats...

Understanding the interactions of an organism and its environment is essential for us to integrate ultimate proximate causation on a global scale. Organism–environment interaction includes all organisms including animals, plants, non-eukaryotes, etc. because them are responsive environmental change those that human-induced. A mechanistic approach important understand why some can cope with others cannot. Here, we present three examples environments ("the poles") changing rapidly how avian...
ABSTRACT Establishment of nonnative fishes has contributed to the decline native worldwide. Efficacy mechanical removal in large streams been difficult ascertain, and responses by after is equivocal. We summarize results efforts on San Juan River, New Mexico, Colorado, Utah, suppress Channel Catfish Common Carp densities through via electrofishing. assessed spatial temporal trends abundant relation fishes. declined river-wide but only decreased upper reaches.

This forum article is the product of interdisciplinary discussion at a conference on climate histories held in Cambridge, United Kingdom, early 2011, with specific aim building network around issue communicating cultural knowledge environmental change. The lead articles, by Kirsten Hastrup as an anthropologist and Simon Schaffer historian science, highlight role agents proxies. These are followed five commentaries, which engage articles through new ethnographic material, set shorter...
The efficacy of topiramate, a novel therapeutic agent approved for the treatment seizure disorders, was evaluated in model traumatic brain injury (TBI). Adult male rats were anesthetized (sodium pentobarbital, 60 mg/kg, i.p.), subjected to lateral fluid percussion (n = 60) or sham 47) and randomized receive either topiramate vehicle at 30 min (30 8, 20 32 h postinjury p.o.). In Study A, memory using Morris water maze 48 postinjury, after which tissue regional cerebral edema. B, animals motor...
Abstract Animals inhabiting urban areas must simultaneously cope with the unique challenges presented by this novel habitat type while exploiting distinctive opportunities it offers. The costs and benefits of living are often assumed to be consistent across time, but may in fact vary depending on features influencing them. Here we examine glucocorticoid levels body condition song sparrows ( Melospiza melodia) resident at rural sites over four consecutive years determine whether these traits,...
Molecular mechanisms governing the anterograde trafficking of nascent G protein-coupled receptors (GPCRs) are poorly understood. Here, we have studied regulation cell surface transport α2-adrenergic (α2-ARs) by GGA3 (Golgi-localized, γ-adaptin ear domain homology, ADP ribosylation factor-binding protein 3), a multidomain clathrin adaptor that sorts cargo proteins at trans-Golgi network (TGN) to endosome/lysosome pathway. By using an inducible system, demonstrated knockdown significantly...

Abstract Human transformation of aquatic systems and the introduction nonnative species increasingly threaten persistence imperiled freshwater fishes. In response, large‐scale mechanical removal fishes has been implemented throughout parts Colorado River basin to aid recovery endangered fishes, but effects these efforts can be difficult quantify. Fisheries population models for predicting outcomes harvest regulations have widely used prevent overfishing commercial game stocks. Here, we...
In an effort to understand the complexity of genomic responses within selectively vulnerable regions after experimental brain injury, we examined whether single apoptotic neurons from both CA3 and dentate differed those in uninjured brain. The mRNA individual active caspase 3(+)/terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling [TUNEL(–)] 3(+)/TUNEL(+) pyramidal granule brain-injured mice were amplified compared with nonlabeled brains. Gene analysis revealed...
Stable isotope ecology has made great strides in quantifying energy transfer through food webs. However, trophic inferences gleaned from field-collected data can be limited when isotopic turnover and discrimination factors (Δ 13 C or Δ 15 N) are unknown. We quantified using an diet switch the endangered Colorado pikeminnow (Ptychocheilus lucius). The estimated half-life for δ was 62 days a 33% increase mass N averaged 133 52% mass. Growth metabolic processes both contributed to rates of...
Dehydroepiandrosterone ( DHEA ) is a testosterone/oestrogen precursor and known modulator of vertebrate aggression. Male song sparrows Melospiza melodia morphna show high aggression during breeding nonbreeding life‐history stages when circulating levels are high, low molt low. We previously showed that androgen receptor aromatase mRNA expression higher and/or in brain regions associated with reproductive aggressive behaviour, although the potential role mediating these seasonal changes...

Research across a range of biological subdisciplines and scales, ranging from molecular to ecosystemic, provides ample evidence that living systems generally exhibit both degree resistance disruption an ability recover following disturbance. Not only do mechanisms robustness resilience exist between systems, but those ubiquitous scalable commonalities in pattern function. Mechanisms such as redundancy, plasticity, interconnectivity, coordination subunits appear be crucial internal players...
