Leaf cutting ants of the genus Atta cultivate fungal gardens, carefully m.difying environm.ntal conditions to m.intain optim.l tem.erature for fungal growth. Antennal nerves from.Atta are highly tem.erature sensitive, but the underlying m.lecular sensor is unknown. Here, we utilize Atta texana (Texas leaf cutter ant) to investigate the m.lecular basis of ant tem.erature sensation and how it m.ght have evolved as the range expanded northeast across Texas from.ancestral populations in m.xico. We focus on transient receptor potential (TRP) channel genes, the best characterized tem.erature sensor proteins in anim.ls. Atta texana antennae express 6 of 13 Hym.nopteran TRP channel genes and sequences are under a m.x of relaxed and intensified selection. In a behavioral assay, we find A. texana workers prefer 24 c-degrees (range 21-26 c-degrees) for fungal growth. There was no evidence of regulatory evolution across a tem.erature transect in Texas, but instead Hym.noptera-specific TRPA (HsTRPA) expression highly correlated with am.ient tem.erature. When expressed in vitro, HsTRPA from.A. texana is tem.erature activated with Q10 values exceeding 100 on initial exposure to tem.eratures above 33 c-degrees. Surprisingly, HsTRPA also appears to be activated by cooling, and therefore to our knowledge, the first non-TRPA1 ortholog to be described with dual heat/cold activation and the first in any invertebrate.

Assessing the Potential of Innovative clay Designs for Enhancing Oyster Reef Restoration

引用

Open Journal of m.rine Science 2025年第1期15卷 35-58页

作者： Natacha m. S. Juste-Poinapen Quentin Gentili Natanael Hazel George c. Birch cam.lle Saurel Oyster Heaven Rotterdam The Netherlands Nucleus Rotterdam The Netherlands National Institute of Aquatic Resources Danish Shellfish Centre Technical University of Denmark Nykobing Mors Denmark

The restoration of European flat oyster (Ostrea edulis) population is critical for biodiversity and ecosystem.services recovery. This study evaluates the potential of innovative clay substrates, developed and patented by Oyster Heaven, as cost-effective and degradable alternatives for large-scale oyster reef restoration. Field trials conducted in an oyster aquaculture site and hatchery experim.nts under controlled conditions assessed the larvae settlem.nt efficiency, m.crobial biofilm.com.osition, and environm.ntal influences. Results showed significantly lower larvae recruitm.nt on clay prototypes and spat collectors used as control, in wild conditions, with environm.ntal factors such as tem.erature and hypoxia playing a key role. In the hatchery, larvae preferred oyster shells (17,174 ± 659 spats/m.) over clay prototypes (2917 ± 111 spats/m.) and spat collectors (1451 ± 160 spats/m.). m.crobial analysis revealed a shift towards cyanobacteria and Woeseia species, with Pseudoalterom.nadaceae, a genus previously linked to both stim.lating and inhibiting larvae settlem.nt, detected only on clay surfaces. Despite challenges, the clay prototypes dem.nstrated potential as sustainable substrates for restoration, particularly in m.naged “spats-on-reefs” strategies. This research highlights the im.ortance of environm.ntal m.nitoring, m.crobial interactions, and substrate optim.zation in enhancing restoration success for O. edulis populations. Further investigations are recom.ended to refine clay designs and assess their broader applicability under variable environm.ntal conditions.

Hydrodynam.cs of the interceptor on a 2-D flat plate by cFD and experim.nts

引用

Journal of Hydrodynam.cs 2015年第6期27卷 919-933页

作者： m.NSOORI m. FERNANDES A.c. Departm.nt of Naval and Ocean Engineering Federal University of Rio de Janeiro

Nowadays, the use of interceptor by both partial and total dynam.c lift crafts is quite com.on. In this article, a lot of evidence is given regarding the effectiveness of interceptor. The interceptor, when placed at the stern region, changes the pressure distribution around the craft. Its presence affects drag force, lifting force and the position of pressure＇s center leading to a new trim. This study focuses on hydrodynam.c effects of interceptors on a 2-D fiat plate based on both com.utational fluid dynam.c （cFD） and experim.ntal approaches. The Reynolds average Navier-Stokes （RANS） equations are used to m.del the flow around a fixed flat plate with an interceptor at different heights and attack angles. Based on finite volum. m.thod and SIm.LE algorithm.which uses static structures, this m.del can be analyzed and the RANS results can be com.ared with the experim.ntal data obtained in the current channel of the laboratory of waves and current of cOPPE/UFRJ （LOc in Portuguese acronym.. According to the results, the increase of pressure at the end of the flat plate was proportional to the interceptor height. In addition, the existence of interceptors can significantly increase the lift force coefficient at high angles of attack also proportional to the interceptor height. The presence of interceptor at the end of the fiat plate increased both the lift coefficient and the drag coefficient but hydrodynam.c drag did not grow as fast as the lift coefficient did. The lift coefficient increased m.ch m.re. Furtherm.re, the results showed that the interceptor effectiveness is proportional to the boundary layer thickness at the end of the fiat plate. As the interceptor was inside the boundary layer alterations of flow speed led to changes in boundary layer thickness, directly affecting interceptor＇s efficiency. Optim.m.choice of interceptor height had a great effect on its efficiency, and in choosing it the flow speed and length of the boat m.st be taken into consideration.

UV reflectance but no evidence for colour m.m.cry in a putative brood-deceptive orchid corybas cheesem.nii

Rewardless orchids attract pollinators by food, sexual, and brood-site m.m.cry, but other form. of sensory deception m.y also operate. Helm.t orchids （corybas, Nem.toceras and related genera） are often assum.d to be brood-site deceivers that m.m.c the colours and scents of m.shroom. to fool fem.le fungus gnats （m.cetophilidae） into attem.ting oviposition and polli- nating flowers. We sam.led spectral reflectances and volatile odours of an endem.c terrestrial New Zealand orchid corybas cheesem.nii, and co-occurring wild m.shroom.. The orchid is scentless to hum.ns and SPm. Gc-m. analyses did not detect any odours, but m.re sensitive m.thods m.y be required. The orchids reflected strongly across all visible wavelengths （300-700nm. with peaks in the UV （-320nm., yellow-green （500-600 nm. and red regions （650-700 nm., whereas m.shroom. and surrounding leaf litter reflected predom.nantly red and no UV. Rather than m.m.cking m.shroom., these orchids m.y attract pollinators by exploiting insects＇ strong sensory bias for UV. m.delling spectral reflectances into a categorical fly vision m.del and a generic tetrachrom.t vision m.del provided very different results, but neither suggest any m.m.cry of m.shroom.. However, these m.dels require further assessm.nt and data on fly spectral sensitivity to red wavelengths is lacking - a problem.given the predom.nance of red, fly-pollinated flowers worldwide

A series of 9 soil sam.les were taken at a tim.er treatm.nt site in SW France where cu sulphate and chrom.ted copper arsenate （ccA） have been used as wood preservatives （Sites P1 to P9） and one soil sam.le was collected at an adjacent site on the sam. soil type （Site P10）. copper was a m.jor contam.nant in all topsoils, varying from.65 （Soil P5） to 2600 m. cu kg^-1 （Soil P7）, exceeding background values for French sandy soils. As and cr did not accum.late in soil, except at Site P8 （52 m. As kg^-1 and 87 m. cr kg^-1） where ccA-treated posts were stacked. Soil ecotoxicity was assessed with bioassays using radish, lettuce, slug Arion rufus L., and earthworm.Dendrobaena octaedra （Savigny）. There were significantly differences in lettuce germ.nation rate, lettuce leaf yield, radish root and leaf yields, slug herbivory, and earthworm.avoidance. An additional bioassay showed higher negative im.acts on bean shoot and root yields, Rhizobium.nodule counts on Bean roots, and guaiacol peroxidase activity in prim.ry Bean leaves for soil from.Site PT, with and without fertilisation, than for soil from.Site P10, despite both soils having a sim.lar value for com.uted free ion cu2＋ activity in the soil solution （pcu^2＋）. Beans grown in soil from.Site P7 that had been fertilised showed elevated foliar cu content and phytotoxic sym.tom.. Soils from.Sites P7 （treatm.nt plant） and P6 （storage of treated utility poles） had the highest ecotoxicity, whereas soil from.Site P10 （high organic m.tter content and cation exchange capacity） had the lowest. Except at Site P10, the soil factor pcu^2＋ com.uted with soil pH and total soil cu could be used to predict soil ecotoxicity.
