Improving estimation of woody aboveground biomass in drylands by accounting for disturbances and spatial heterogeneity

Liana Kindermann, Magnus Dobler, Daniela Niedeggen & Anja Linstädter
Existing methodologies for estimating woody aboveground biomass and carbon stored therein have been developed for forests but are not tailored to the vast dryland ecosystems where vegetation is heterogenous and highly disturbed. Still, those methods are widely applied with questionable results and possible problematic implications, not only for biomass quantification but also for disturbance ecology, biodiversity research, and ecosystem service assessments. We hereby propose a new methodology especially designed to encompass small, disturbed, and irregular...

Microfluidic EPG Recordings Show Striking Pharyngeal Pumping Phenotype in a C. elegans Alzheimer's Disease Model

Janis C Weeks, Kristen J Robinson, Benedicta Wanjeri, Philip F Copenhaver & William M Roberts
Strain CL4176 accumulates human amyloid-β1-42 in body wall muscles after animals are shifted from 15 to 25 oC, causing paralysis (Link et al. 2003). We temperature-shifted worms at early L4 and quantified pharyngeal pumping at 48 h using a microfluidic electropharyngeogram (EPG) recording platform (Lockery et al. 2012; Weeks et al. 2016). Recordings were made in M9 buffer with 10 mM serotonin and analyzed by automated pump-recognition software. At 48 h, control CL802 worms showed...

Mutations in KCNQ potassium channels cause pharyngeal pumping defects in C. elegans

Yoanne Clovis, Alexis Webb, Carl Turner & Bill Roberts
Pumps were stimulated with 10mM 5HT in M9 recorded as electropharyngeograms (EPGs) for 2 minutes in a NemaMetrix ScreenChip, and analyzed using NemAnalysis software (NemaMetrix). The null mutant strains kqt-1(aw3) and kqt-3 (aw1) were kindly donated by Dr. Aguan Wei (Wei et al., 2002) A) Pump frequency in kqt-1(aw3) animals was significantly lower than in N2s, while kqt-3(aw1) worms showed an increase in pump frequency (*p<0.05; ***p<0.01; 1-tailed Mann-Whitney U-test; n = 21-23 worms in...

Early sex reversal during embryonic development in the Nile tilapia

Carole Rougeot, Samane Y. Kanfitine, Christian Prignon, Vincent Gennotte & Charles Mélard
The aim of this work was to study the effect of hormonal sex-reversal treatment during embryonic development of Nile tilapia. XX and XY embryos were incubated in 17 α-methyltestosterone or in 17α-ethynylestradiol during embryonic development. Mean survival rates of embryos 5 days post-hatching ranged from 13.1% to 63.9%. XY embryos incubated in E2 displayed a significant proportion of females (from 50.6 to 79.0%) and XX embryos incubated in MT a significant proportion of males (from...

Motility characteristics of spermatozoa in cod (Gadus morhua) and hake (Merluccius merluccius)

Jacky Cosson, Anne-Laure Groison, Marc Suquet & Christian Fauvel
As in many marine fish, motility is triggered by osmotic pressure (OP) in cod and hake spermatozoa and motility ranges several minutes with a high velocity (above 50 μm/s) period restricted to 100 s. A decrease in the flagellar beat frequency (BF) is partly responsible of this briefness. Detailed observations of the flagella during the motility period showed: 1) sea water provokes OP damages (blebs) which impair the correct wave propagation 2) waves become restricted...

Gene bashing of ceh-6 locus identifies genomic regions important for ceh-6 rectal cell expression and rescue of its mutant lethality

Arnaud Ahier, Shashi Kumar Suman & Sophie Jarriault
Loss of the activity of certain genes, such as ceh-6, can lead to lethality at early developmental stages, precluding the study of their function later on during development. Indeed, it was reported that more than 80% of ceh-6(mg60) animals died during embryogenesis exhibiting various phenotypes, including an abnormal rectal area and absent excretory canal cell (Bürglin and Ruvkun 2001). mg60 is a 1.4kb deletion allele that removes ceh-6 second exon and is believed to cause...

Review of Giuris (Teleostei: Eleotridae) from Indo-Pacific islands, with description of three new species

Philippe Keith & Marion I. Mennesson
Giuris species from the Indo-Pacific area are reviewed. Eight species are recognized including three new species. These are described using genetic and morphomeristic approaches. The species differ by a high percentage of divergence in partial COI gene (495 bp) and by several characters including the number of pectoral fin rays, the number of scales in transverse forward series, the number of scales around the eye, the interorbital length, and the body depth at first dorsal...

Reevaluation of the Perciformes from the Late Cretaceous Marília Formation of Brazil and its confirmation as a Siluriformes

Paulo M. Brito, François J. Meunier & Yuri M. Alves
A fossil spine, originally described as belonging to Perciformes from the Late Cretaceous Marília Formation, Bauru Basin, Southeastern Brazil, is here restudied based on paleohistology. In addition to the overall morphology of the spine, our histological results point to the presence of pseudolamellar bone with embedded star-shaped osteocytes. These results confirm the recent redescription of this specimen as a Siluriformes, and confirm the absence, so far, of Percomorpha in freshwater deposits from the Cretaceous of...

Seasonal-related homologous regulation of goldfish liver Estrogen receptor subtypes

Erik R. Nelson & Hamid R. Habibi
Treatment with estrogen was found to increase expression of estrogen receptor subtypes (ERα, ERβ1 or ERβ2) in the liver of goldfish during regressed gonadal stage. Here, we test the hypothesis that homologous ER regulation may occur in a seasonal-dependant manner. To make seasonal comparison, we investigated homologous regulation of the ERs expression in the livers of goldfish at mid-late stage of gonadal recrudescence. The results demonstrate that homologous regulation of the ER subtypes are different...
