Figure 9 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 9. Video sequence of an adult Desmognathus quadramaculatus capturing a cricket under water using jaw prehension. The tongue is raised from the floor of the mouth, but the salamander lunges forward and grasps the prey with the jaws. Note the slight hyobranchial depression in the last frame. Background is 1 cm grid.

Figure 4 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 4. Bar graphs of gape cycle durations and lunge distances of four species of larval plethodontids showing differences. Bars sharing a letter are not significantly different from one other. G. porphyriticus (abbreviated Gp) has a significantly longer gape cycle than D. quadramaculatus (Dq) and P. ruber (Pr). D. quadramaculatus lunges significantly farther than G. porphyriticus and P. ruber. E. wilderae (Ew) is not significantly different from other species either with regard to gape cycle duration or lunge distance. Number of feedings (n) is given for each species.

Figure 11 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 11. Video sequence of an adult Stereochilus marginatus capturing a tubifex worm aquatically using jaw prehension. The salamander lunges forward and grasps the worm with the jaws. Note the substantial buccal expansion in the last frame, the rapid gape cycle compared to Figs 9 and 10, and how the prey does not move toward the salamander as it does in larval prey capture (see Figs 2 and 3). Scale bar = 1 cm.

Figure 6 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 6. Box plots of gape cycle duration for all stages and species. Adults are shown as shaded boxes, and larvae as open boxes. Note the much longer gape cycles of the adults compared to the larvae. S. marginatus adults fall closer to the larvae of other species than to the adults. Adult G. porphyriticus and P. ruber are more variable in gape cycle duration when feeding aquatically than terrestrially. Box edges represent lower and upper quartiles (showing skewness), the length of the box is the interquartile range (showing dispersion), the vertical line is the median (showing location), and the horizontal lines are drawn to the smallest and largest values within 1.5 interquartile ranges of the box edges. Dots indicate the entire range of durations. When only one feeding was recorded, only a vertical line is shown. Abbreviations: Dm = D. marmoratus; Dq = D. quadramaculatus; Ew = E. wilderae; Gp = G. porphyriticus; Pr = P. ruber; Sm = S. marginatus.

Figure 7 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 7. Video sequence of an adult P. ruber capturing a cricket terrestrially using tongue protraction. Note the tongue length and speed of protraction, the free tongue pad, the forward lunge, and the head elevation during tongue retraction and subsequent head dipping. Scale bar = 1 cm.

Figure 15 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 15. Kinematic profiles of aquatic jaw prehension in adult S. marginatus. Note the symmetrical gape profile and the strong hyobranchial depression upon mouth closing, similar to the patterns for suction feeding (see Fig. 5) but with a shallower increase in hyobranchial depression distance. Head movements show the typical pattern of mirroring jaw movements.

Figure 8 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 8. Bar graphs of gape cycle duration and lunge distance for four species of adult plethodontids feeding terrestrially. D. quadramaculatus and G. porphyriticus have significantly longer gape cycle durations than P. ruber, and D. quadramaculatus lunges significantly farther than P. ruber. Bars sharing the same letter are not significantly different from one another. Number of feedings (n) is given for each species.

Figure 2 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 2. High-speed video sequence of a larval D. quadramaculatus capturing a tubifex worm using suction feeding. The salamander depresses the hyobranchial apparatus, expanding the buccal cavity ventrally and sucking the prey from the forceps. The prey moves toward the salamander, while the salamander remains relatively stationary. As in all video sequences presented, time in milliseconds is shown from the onset of mouth opening at zero. Scale bar = 1 cm.

Figure 3 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 3. Video sequence of a larval G. porphyriticus capturing a tubifex worm using suction feeding. The salamander raises the head during mouth opening to direct the gape at the prey, and the buccal cavity is expanded ventrally, reaching maximum expansion as the mouth closes. Background is 5 mm grid.

Data for: Feeding frequency does not interact with BPA exposure to influence metabolism of behaviour in zebrafish (Danio rerio)

Resource limitation can constrain energy (ATP) production, and thereby affect locomotion and behaviour such as exploration of novel environments and boldness. Consequently, ecological processes such as dispersal and interactions within and between species may be influenced by food availability. Energy metabolism, and behaviour are regulated by endocrine signaling, and may therefore be impacted by endocrine disrupting compounds (EDCs) such as bisphenol A (BPA) derived from plastic manufacture and pollution. It is important to determine the impacts of these novel environmental contexts to understand how human activity alters individual physiology and behaviour and thereby populations. Our aim was to determine whether BPA exposure interacts with feeding frequency to alter metabolism and behaviour. In a fully factorial experiment, we show that low feeding frequency reduced zebrafish (Danio rerio) mass, condition, resting metabolic rates, total distance moved and speed in a novel arena, as well as anxiety indicated by the number of times fish returned to a dark shelter. However, feeding frequency did not significantly affect maximal metabolic rates, aerobic scope, swimming performance, latency to leave a shelter, or metabolic enzyme activities (citrate synthase and lactate dehydrogenase). Natural or anthropogenic fluctuation in food resources can therefore impact energetics and movement of animals with repercussions for ecological processes such as dispersal. BPA exposure reduced LDH activity and body mass, but did not interact with feeding frequency. Hence, behaviour of adult fish is relatively insensitive to disruption by BPA. However, alteration of LDH activity by BPA could disrupt lactate metabolism and signalling and together with reduction in body mass could affect size-dependent reproductive output. BPA released by plastic manufacture and pollution can thereby impact conservation and management of natural resources.

Data from: Neuropeptide signalling shapes feeding and reproductive behaviours in male C. elegans

Sexual dimorphism occurs where different sexes of the same species display differences in characteristics not limited to reproduction. For the nematode Caenorhabditis elegans, in which the complete neuroanatomy has been solved for both hermaphrodites and males, sexually dimorphic features have been observed both in terms of the number of neurons and in synaptic connectivity. In addition, male behaviours, such as food-leaving to prioritise searching for mates, have been attributed to neuropeptides released from sex-shared or sex-specific neurons. This dataset compiles the results obtained in our investigation of how LURY-1 neuropeptides regulate feeding and mating behaviours in C. elegans. These contain confocal micrographs and z-stacks of fluorescence reporter imaging used to demonstrate the expression pattern of lury-1 and npr-22, including micrographs used for cell identification of lury-1 expressing neurons in the male worm. Other behavioural data from mating efficiency assays, pharyngeal pumping assays and food leaving assays are also shown. These include male turning behaviour examined through video recordings of male mating; the videos are also included as part of this dataset. In this study ("Neuropeptide signalling shapes feeding and reproductive behaviours in male C. elegans"), our findings indicate sex-specific roles of this peptide in feeding and reproduction in C. elegans. This provides further insight into neuromodulatory control of sexually dimorphic behaviours.

Sexually antagonistic coevolution of the male nuptial gift and female feeding behaviour in decorated crickets

The evolution of nuptial gifts has traditionally been considered a harmonious affair, providing benefits to both mating partners. There is growing evidence, however, that receiving a nuptial gift can be actively detrimental to the female. In decorated crickets (Gryllodes sigillatus), males produce a gelatinous spermatophylax that enhances sperm transfer but provides little nutritional benefit and hinders female post-copulatory mate choice. Here, we examine the sexually antagonistic coevolution of the spermatophylax and the female feeding response to this gift in G. sigillatus maintained in experimental populations with either a male-biased or female-biased adult sex ratio. After 25 generations, males evolving in male-biased populations produced heavier spermatophylaxes with a more manipulative combination of free amino acids than those evolving in female-biased populations. Moreover, when the spermatophylax originated from the same selection regime, females evolving in male-biased populations always had shorter feeding durations than those evolving in female-biased populations indicating the evolution of greater resistance. Across populations, female feeding duration increased with the mass and manipulative combination of free amino acids in the spermatophylax suggesting sexually antagonistic coevolution. Collectively, our work demonstrates a key role for interlocus sexual conflict and sexually antagonistic coevolution in the mating system of G. sigillatus.

Pigs feeding behaviours from two different farms, including behaviours during a tail biting event

These data are linked to the article from Ollagnier et al, 2021 (https://doi.org/10.1101/2021.05.11.443554) Data desription This data set comprises the feeding behaviours of two herds of grower-finisher pigs weighing between 25 and 100 kilograms. One data set originates from a testing boar station in Sweden and contains data collected from October 2004 to July 2007. The data set comes from a previous retrospective study that Wallenbeck and Keeling published in 2013. The second data set contains data from the experimental pig farm of Agroscope and comprises recordings from November 2018 to April 2020. As tail docking is prohibited in Sweden and in Switzerland, the data are from pigs with intact tails. The Swedish data set includes data from 42 pens (21 TB and 21 CTL ) of boars (purebred Yorkshire, Landrace or Hampshire) recorded 70 days before and after the TB date. Boars were housed in groups of 7 to 14 animals per pen. Each pen measured 15.7 m2 and had a slatted floor and plain resting area. All pigs had ad libitum access to the pelleted feed, which was optimised according to the Swedish nutrition norms for fattening pigs [25]. Water was provided ad libitum and straw was offered daily. The Swiss data set consisted of 23 pens (six TB and 17 CTL) of females and castrated male pigs (Swiss Large White), recorded 100 days before and after the TB date. Twenty pens (18 m2) contained 11 to 15 pigs each and were equipped with two automatic feeders; three pens (78 m2) were equipped with eight automatic feeders for 31 to 55 pigs each. All pens had straw in racks and sawdust on the floor. Water was available ad libitum through nipple drinkers. The pelleted finisher diet was formulated to have 20% lower dietary crude protein and essential amino acids compared to a standard diet formulated according to the Swiss feeding recommendations for pigs. Data structure: Three observations were considered to describe the feeding behaviours of pigs.  DFV: Number of visits to the feeder (from 0:00 to 23:59:59 that date), unit=n,  DFC: Total feed consumption (from 0:00 to 23:59:59 that date), unit=g StdFC: Daily standard deviation of the feed consumption at each visit, unit=g The data set also contains the following information: Farm: origin of the feeding behavior data (Swiss or Swedish farm) ID: unique identification of the pig date: date at which the feeding behavior is recorded, numerical format. TBSTART: date at which the tail biting event started in tail biting pens. An arbitrary date has been taken for control pens, numerical format. PenID: unique identification of the pen. PenType: control (K) or tail biting (TB). A pen was assigned to the TB category if at least one pig had to be treated for tail damages.
