Recent studies suggest that the developmental toxicity associated with childhood lead poisoning may be attributable to interactions of Pb(II) proteins containing thiol-rich structural zinc-binding sites. Here, we report detailed in such sites, providing critical insights into mechanism by which alters activity these proteins. X-ray absorption spectroscopy bound peptides reveals binds a three-coordinate Pb(II)-S3 mode, while Zn(II) is known bind four-coordinate mode This coordination...
Abstract Long-distance terrestrial migrations are imperiled globally. We determined both round-trip migration distances (straight-line measurements between migratory end points) and total annual movement (sum of the successive relocations over a year) for suite large mammals that had potential long-distance movements to test which species displayed longest both. found caribou likely do exhibit on planet, but, course year, gray wolves move most. Our results were consistent with trophic-level...
The origin of Borneo's elephants is controversial. Two competing hypotheses argue that they are either indigenous, tracing back to the Pleistocene, or were introduced, descending from imported in 16th–18th centuries. Taxonomically, have been classified as a unique subspecies placed under Indian Sumatran subspecies. If shown be indigenous population, this would extend natural species range Asian elephant by 1300 km, and therefore Borneo much greater conservation importance than if feral...
Here, we report that lead−thiolate charge-transfer bands (250−400 nm) can be used to monitor lead binding cysteine-rich sites in proteins and the application of this technique determine thermodynamics a series structural zinc-binding domains. These studies reveal Pb2+ binds tightly domains with dissociation constants range from KdPb = 10-9 10-14 M, depending on number cysteine residues metal-binding site. Competition experiments Zn2+ two striking conclusions: first, metals rapidly...
Many salmon populations in both the Pacific and Atlantic Oceans have experienced sharply decreasing returns high ocean mortality past two decades, with some facing extirpation if current marine survival trends continue. Our inability to monitor movements of fish or directly measure their precludes experimental tests theories concerning factors regulating populations, thus limits scientific advance many aspects fisheries management conservation. Here we report a large-scale synthesis movement...
The jumbo or Humboldt squid, Dosidicus gigas , is an important fisheries resource and a significant participant in regional ecologies as both predator prey. It the largest species oceanic squid family Ommastrephidae has known potential fecundity of any cephalopod, yet little understood about its reproductive biology. We report first discovery naturally deposited egg mass well spawning eggs captivity. was found warm water (25–27°C) at depth 16 m far larger than masses previously reported....
Animal telemetry is the science of elucidating movements and behavior animals in relation to their environment or habitat. Here, we focus on aquatic species (marine mammals, sharks, fish, sea birds turtles) so are concerned with animal as they move through above world's oceans, coastal rivers, estuaries great lakes. devices ("tags") yield detailed data regarding responses coupled ocean–atmosphere physical which moving. has matured describe a developing US Telemetry Network (ATN) observing...
Abstract The forage maturation hypothesis (FMH) states that energy intake for ungulates is maximised when biomass at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest resource selection should vary across ungulate species. By combining GPS relocations with remotely sensed data on characteristics surface water, we quantified the effect of body size system in determining movements 30 populations hindgut fermenters (equids) ruminants biomes....
Abstract Studying nomadic animal movement across species and ecosystems is essential for better understanding variability in nomadism. In arid environments, unpredictable changes water forage resources are known drivers of movements. Water vary temporally but often spatially stationary, whereas foraging both variable. These differences may lead to different types movements: forage‐ vs. water‐driven Our study investigates these two nomadism relation resource gradients from mesic steppe xeric...
Abstract Most large herbivores in arid landscapes need to drink which constrains their movements and makes them vulnerable disturbance. Asiatic wild ass or khulan ( Equus hemionus ) were widespread abundant throughout the of Central Asia Mongolia, but have undergone dramatic population declines range constrictions; denying access water is believed played a major role. Mongolia’s South Gobi Region now houses world largest remaining population, undergoing rapid land use changes. Khulan poorly...
Zinc binding to the two Cys(4) sites present in DNA-binding domain (DBD) of nuclear hormone receptor proteins is required for proper folding and protein activity. By utilizing Co(2+) as a spectroscopic probe, we have characterized metal-binding properties structural zinc-binding found DBD human estrogen alpha (hERalpha-DBD) rat glucocorticoid (GR-DBD). The affinity was determined relative zinc finger consensus peptide, CP-1. Using known dissociation constant from CP-1, constants cobalt...
The Mongolian Gobi-Eastern Steppe Ecosystem is one of the largest remaining natural drylands and home to a unique assemblage migratory ungulates. Connectivity integrity this ecosystem are at risk if increasing human activities not carefully planned regulated. Gobi part supports population Asiatic wild ass (Equus hemionus; locally called "khulan"). Individual khulan roam over areas thousands square kilometers scale their movements among described for terrestrial mammals, making them...

Abstract Internally implanted acoustic tags represent a potentially valuable approach to assessing the seasonal migration and distribution patterns of Pacific herring Clupea palasii .

Relatively low mortality (4%) tag shedding (4%), as well growth similar observed control fish after 135 d, indicate...
ABSTRACT The Census of Marine Life was a 10‐year, international research effort to explore poorly known ocean habitats and conduct large‐scale experimentation with new technology. goal 2010 in its mission statement describe what did live the oceans, does will ocean. Many findings techniques from census may prove valuable making transition, which many governments have publicly endorsed, single‐species fisheries management more holistic ecosystem management. researchers sampled continental...
Research and conservation of wide-ranging wild equids in most cases necessitate capture handling individuals. For free-roaming Mongolian khulan (Equus hemionus hemionus), also known as the khulan, involves a strenuous, high-speed chase, physiologic responses have yet to be elucidated. We analyzed sequential arterial blood gas (ABG) samples proxy for respiratory metabolic status during capture-related anesthesia. recorded precise chase induction times monitored vital parameters ABG from...
