The Rattlesnakes They Keep in the Life Sciences Building Remind Me of My Dog

The Rattlesnakes They Keep in the Life Sciences Building Remind Me of My Dog Katie Berta (bio) Keywords Katie, Bertie, Rattlesnakes, animal, poison, danger, life and death the way they lay their chins on a rock to get a minute of rest, the way their eyesget heavily lidded as they stare off out of their tanks—but so do the dead mice (one rat) that litter their cages around noon, their little bodiescurled around some unseen center, their tiny, ratty feet with scales just likethe rattlesnakes'. There they are: mammals. Same team as me. The biggest snakeis an albino so huge his scales, when they lift from his bodyas he curves around a rock or rodent, look like big, dry flakes of oatmeal.I have trouble relating to snakes. This one, if we met him in our yard, would pumpso much poison into my dog's leg, he'd lie down, yelping, curling, like one of the mice prekilledin the tanks, onto his tummy, protecting what's left. I can't thinkof my dog dying in front of me in the yard without wanting to chop this snake to pieceswith a shovel, but when I see him here, bored, he makes me think of a dog sleeping,not dying. I had to stop watching nature shows because of this—not knowing whoto relate to—used to root for the prey not the predator butthe wolf pups die too, if they don't get anything to eat, the lion cubs, the killerwhales. Thinking this way inevitably makes you cry helplessly in the dark,the blue light of the television's vast sea, full of creatures vying for this,this thing you're doing even as you just sit here, washing over you,drowning you. Yes, inevitable is right. I know someone has to die.All of us, in fact. I just wish the dog could live. The rats too, the snake, me.

First false darkling beetle from mid-Cretaceous Burmese amber (Coleoptera: Melandryidae)

Tihelka, E., Huang, D. & Cai, C. 4 October 2019. First false darkling beetle from mid-Cretaceous Burmese amber (Coleoptera: Melandryidae). Alcheringa 44, 169–175. ISSN 0311-5518 The false darkling beetles (Melandryidae) are a small but morphologically diverse and taxonomically problematic family belonging to the polyphagan superfamily Tenebrionoidea. The Mesozoic record of Melandryidae is sparse, with only three described species. A new genus and species, Longicrusa jaracimrmani gen. et sp. nov., is described here from the mid-Cretaceous Burmese amber (ca 99 Ma), representing the oldest false darkling beetle described to date. The modified maxillary palpi of L. jaracimrmani gen. et sp. nov. suggest that the species probably fed on fungi, and its prominent pectinate spurs indicate that the ability to jump had already developed in false darkling beetles by the mid-Cretaceous. A checklist of fossil melandryid beetles is provided.

Library Services and Spaces: Addressing the Needs of a Changing Campus

The OHSU Library has undergone many changes in the last two years to serve its users better. With the opening of the Collaborative Life Sciences Building (CLSB), a joint venture between OHSU, PSU and OSU, there was an opportunity to design a library space from the ground up. With changes in the MD curriculum and changes in library operations, there was a chance to redesign existing library space in the Biomedical Information Communication Center (BICC) to better fit the current and future needs of the OHSU community.

Debrot, Kralendijk, Bonaire, Caribbean Netherlands *Corresponding author: patrick.lyons5@gmail.com ABSTRACT: Alpheid shrimps and gobiid fishes engage in a mutualism in which shrimp construct burrows that are co-habited with gobies and used as refuge from predators by both. Gobies act as sentinels for shrimp. In the western Atlantic, different goby species have been hypothesized to have a facultative (Ctenogobius saepepallens) and obligate (Nes longus) association with the shrimp Alpheus floridanus. I compared various behaviors among these 2 gobies and another goby that occasionally associates with shrimp (Coryphopterus glaucofraenum). The putatively obligate goby had the greatest preference for shrimp burrows versus other shelters, had the greatest partner fidelity, and facilitated more emergence by shrimp by remaining for longer periods at shrimp burrow entrances. These findings provide evidence that in shrimp-goby mutualism, the more specialized and dependent mutualist gobies provide greater services to their shrimp partners.

The highly conserved KEOPS/EKC complex is essential for a universal tRNA modification, t6A

The highly conserved Kinase, Endopeptidase and Other Proteins of small Size (KEOPS)/Endopeptidase-like and Kinase associated to transcribed Chromatin (EKC) protein complex has been implicated in transcription, telomere maintenance and chromosome segregation, but its exact function remains unknown. The complex consists of five proteins, Kinase-Associated Endopeptidase (Kae1), a highly conserved protein present in bacteria, archaea and eukaryotes, a kinase (Bud32) and three additional small polypeptides. We showed that the complex is required for a universal tRNA modification, threonyl carbamoyl adenosine (t6A), found in all tRNAs that pair with ANN codons in mRNA. We also showed that the bacterial ortholog of Kae1, YgjD, is required for t6A modification of Escherichia coli tRNAs. The ATPase activity of Kae1 and the kinase activity of Bud32 are required for the modification. The yeast protein Sua5 has been reported previously to be required for t6A synthesis. Using yeast extracts, we established an in vitro system for the synthesis of t6A that requires Sua5, Kae1, threonine, bicarbonate and ATP. It remains to be determined whether all reported defects of KEOPS/EKC mutants can be attributed to the lack of t6A, or whether the complex has multiple functions.

Large-scale manipulations reveal that top-down and bottom-up controls interact to alter habitat utilization by saltmarsh fauna

Fleeger1, Linda A. Deegan2 1202 Life Sciences Building, Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana 70803, USA 2The Ecosystems Center, Marine Biological Laboratory, 7 MBL Street, Woods Hole, Massachusetts 02543, USA *Email: djohn46@lsu.edu ABSTRACT: We used ecosystem-wide predator removal and nutrient enrichment to examine top-down and bottom-up forces on saltmarsh fauna. We reduced the killifish Fundulus heteroclitus by ~60%, which elicited significant increases (2 to 4×) in hydrobiid snails Hydrobia spp., suggesting top-down control. The talitrid amphipod Uhlorchestia spartinophila was the most abundant species of epifauna in the creek-bank Spartina alterniflora habitat. Our elevated water column nutrients (~70 µmol l–1, ~10× background) and predator reduction treatments alone both yielded non-significant increases in amphipod abundance, suggesting weak top-down and bottom-up control over this species. However, treatments interacted antagonistically in this habitat such that amphipod abundances were lower than would be expected by an additive response to both treatments. We found corresponding amphipod abundance increases in the adjoining creek-wall habitat, suggesting that amphipods move under the influence of our treatments from the marsh edge onto the creek wall, possibly as a result of an increased incidence of a parasitic (i.e. trematode Levinseniella sp.) infection. Coincident to increased amphipods on creek walls, semipalmated sandpipers Calidris pusilla, amphipod predators, increasingly foraged in creek channels in combined treatments (~30× higher than controls based on unreplicated creek systems). Our results suggest that top-down and bottom-up effects may at times be difficult to detect in small, single-factor studies because of inter-habitat movements of target species and redundant predation. Because the effects of stressors may not be limited to one part of the landscape even for small, motile fauna, landscape-level studies may generally be needed to capture responses to anthropogenic activities.

Potassium channels play an important role in the regulation of vascular smooth muscle tone and, thus, contribute to the regulation of blood pressure, blood flow, and microvascular exchange.1 These channels importantly participate in the determination of vascular smooth muscle cell (VSMC) membrane potential,1,2 which, in turn, controls Ca2+ influx through voltage-gated Ca2+ channels1,2 and has been implicated in the control of Ca2+ release and Ca2+ sensitivity of VSMCs.1 VSMCs express a diverse array of K+ channels that contribute to the regulation of VSMC function,1 including ≥1 type of vascular ATP-sensitive K+ (KATP) channels.2,3 KATP channels consist of a tetramer of α-pore–forming subunits from the KIR6.X family of inwardly rectifying K+ channels, along with complimentary sulfonylurea receptor (SUR) subunits that are members of the ATP-binding cassette family of proteins.2 The SUR subunits are essential for normal trafficking of KATP channels, modulate channel function, and are the binding sites for sulfonylurea antagonists of these channels, such as glibenclamide.2 Vascular smooth muscle KATP channels appear to be composed of KIR6.1 and SUR2B subunits,2 although some VSMCs may also express KATP channels composed of KIR6.2/SUR2B.3 As originally described, KATP channels open during hypoxia or ischemic conditions when cellular ATP levels fall, decreasing cell excitability and protecting energy-limited cells.2 However, both in vitro and in vivo studies suggest that VSMC KATP channels may be open under resting conditions and contribute to the regulation of VSMC membrane potential and vascular tone.1,2 Importantly, the activity of KATP channels can be modulated by a number of physiologically relevant vasoactive substances and conditions. As their name implies, KATP channels may be activated by decreases in intracellular …
