Jaw morphology and fighting forces in stag beetles.

The Journal of experimental biology

Goyens J, Dirckx J, Aerts P.
PMID: 27436136
J Exp Biol. 2016 Sep 15;219:2955-2961. doi: 10.1242/jeb.141614. Epub 2016 Jul 19.

The jaws of different species of stag beetles show a large variety of shapes and sizes. The male jaws are used as weapons in fights, and they may exert a very forceful bite in some species. We investigated in...

Archerfish fast-start decisions can take an additional variable into account.

The Journal of experimental biology

Reinel CP, Schuster S.
PMID: 27436137
J Exp Biol. 2016 Sep 15;219:2844-2855. doi: 10.1242/jeb.136812. Epub 2016 Jul 19.

The analysis of saccadic decision-making tasks with two or four alternatives has shown what appears to be a general hallmark of decision-making: adding more alternatives decreases speed and accuracy. In their everyday lives, however, animals often select among many...

Multiple sensory modalities used by squid in successful predator evasion throughout ontogeny.

The Journal of experimental biology

York CA, Bartol IK, Krueger PS.
PMID: 27401756
J Exp Biol. 2016 Sep 15;219:2870-2879. doi: 10.1242/jeb.140780. Epub 2016 Jul 11.

Squid rely on multiple sensory systems for predator detection. In this study we examine the role of two sensory systems, the lateral line analogue and vision, in successful predator evasion throughout ontogeny. Squid Doryteuthis pealeii and Lolliguncula brevis were...

Thyroid hormone influences muscle mechanics in carp (Cyprinus carpio) independently from SERCA activity.

The Journal of experimental biology

James RS, Little AG, Tallis J, Seebacher F.
PMID: 27401758
J Exp Biol. 2016 Sep 15;219:2806-2808. doi: 10.1242/jeb.143529. Epub 2016 Jul 08.

Thyroid hormone is a key regulator of metabolism, and in zebrafish, hypothyroidism decreases sustained and burst swimming performance. These effects are accompanied by decreases in both metabolic scope and the activity of sarco-endoplasmic reticulum ATPase (SERCA) in zebrafish. Our...

Spatial learning in the cuttlefish Sepia officinalis: preference for vertical over horizontal information.

The Journal of experimental biology

Scatà G, Jozet-Alves C, Thomasse C, Josef N, Shashar N.
PMID: 27655826
J Exp Biol. 2016 Sep 15;219:2928-2933. doi: 10.1242/jeb.129080.

The world is three-dimensional; hence, even surface-bound animals need to learn vertical spatial information. Separate encoding of vertical and horizontal spatial information seems to be the common strategy regardless of the locomotory style of animals. However, a difference seems...

A minimal cost micropropagation protocol for Dianthus caryophyllus L.-- a commercially significant venture.

Indian journal of experimental biology

Pant M.
PMID: 27145634
Indian J Exp Biol. 2016 Mar;54(3):203-11.

In tissue culture, high production cost of the products restricts their reach. Though tissue culture is a major strength in floriculture it is marred by pricing issues. Hence, we developed a complete regeneration low cost micropropagation protocol for an...

Evolutionary and acclimation-induced variation in the heat-shock responses of congeneric marine snails (genus Tegula) from different thermal habitats: implications for limits of thermotolerance and biogeography.

The Journal of experimental biology

Tomanek L, Somero GN.
PMID: 10518474
J Exp Biol. 1999;202:2925-2936.

Heat stress sufficient to cause cellular damage triggers the heat-shock response, the enhanced expression of a group of molecular chaperones called heat-shock proteins (hsps). We compared the heat-shock responses of four species of marine snails of the genus Tegula...

Metamorphosis in the summer flounder Paralichthys dentatus: changes in gill mitochondria-rich cells.

The Journal of experimental biology

Schreiber AM, Specker JL.
PMID: 10460734
J Exp Biol. 1999;202:2475-2484.

Salinity tolerance changes during larval development and metamorphosis in the summer flounder (Paralichthys dentatus) and other teleosts. The physiological mechanisms responsible for osmoregulation during these early stages of development are not well understood. This study characterized changes in ultrastructure,...

Leptocephalus energetics: metabolism and excretion.

The Journal of experimental biology

Bishop RE, Torres JJ.
PMID: 10460735
J Exp Biol. 1999;202:2485-2493.

Leptocephali are the unusual transparent larvae that are typical of eels, bonefish, tarpon and ladyfish. Unlike the larvae of all other fishes, leptocephali may remain in the plankton as larvae for several months before metamorphosing into the juvenile form....

Effects of sea water and stanniectomy on branchial Ca(2+) handling and drinking rate in eel (Anguilla anguilla L.).

The Journal of experimental biology

van der Heijden AJ, Verbost PM, Bijvelds MJ, Atsma W, Wendelaar Bonga SE, Flik G.
PMID: 10460737
J Exp Biol. 1999;202:2505-2511.

We examined the effects of seawater adaptation and extirpation of the Stannius corpuscles on branchial Ca(2+) flows, gill plasma membrane Ca(2+) transporters and drinking rate of European eels, Anguilla anguilla. Transepithelial Ca(2+) inflow in the gills increased 2 weeks...

Inhibiting ventilatory evaporation produces an adaptive increase in cutaneous evaporation in mourning doves Zenaida macroura.

The Journal of experimental biology

Hoffman TC, Walsberg GE.
PMID: 10518483
J Exp Biol. 1999;202:3021-3028.

We tested the hypothesis that birds can rapidly change the conductance of water vapor at the skin surface in response to a changing need for evaporative heat loss. Mourning doves (Zenaida macroura) were placed in a two-compartment chamber separating...
