Morphological Variation Of Pumpkinseed (Lepomis Gibbosus) With Emphasis On Allometry, Fati̇h Mangit, Mustafa Korkmaz, Sedat Vahdet Yerli̇ Jan 2018

Morphological Variation Of Pumpkinseed (Lepomis Gibbosus) With Emphasis On Allometry, Fati̇h Mangit, Mustafa Korkmaz, Sedat Vahdet Yerli̇

Turkish Journal of Zoology

Pumpkinseed(Lepomis gibbosus)is an exotic fish species widely distributed in Europe and it has expanded its distribution area in Turkey since its first report in 1982. It is well known that invasive species like L. gibbosus adapt to introduced habitats relatively well. In order to evaluate morphological variation within this invasive species, sampling was carried out in June 2012 and May 2013 in the Aegean and Thrace regions, respectively. Body-form variability in sampled populations of L. gibbosus was investigated using landmark-based geometric morphometrics. L. gibbosus showed significant geographic- and habitat-based differences with and without allometric standardization. However, outcomes of these results …

Distribution And Diversity Of Earthworm (Annelida, Clitellata)Populations Across Four Land Use Types In Northern Cameroon, Michel Mathurin Kamdem, Patricks Voua Otomo, Albert Ngakou, Nicolas Njintang Yanou Jan 2018

Distribution And Diversity Of Earthworm (Annelida, Clitellata)Populations Across Four Land Use Types In Northern Cameroon, Michel Mathurin Kamdem, Patricks Voua Otomo, Albert Ngakou, Nicolas Njintang Yanou

Turkish Journal of Zoology

Earthworms are present in all types of soil. Changes in land use influence populations of earthworms. However, information on the dynamics of earthworm populations in northern Cameroon is not available. This paper highlights the research carried out on the abundance, biomass, and diversity of earthworm populations throughout four types of land use in northern Cameroon. Earthworms were sampled throughout the rainy season in three regions, across pastures, woody savannahs, grass savannahs, and fields, using formaldehyde and hand sorting. Earthworms of the woody savannah and pasture have a high mean density (63 and 45 individuals/m2, respectively) and biomass (25.2 and 22 …

Lichens In The Nests Of European Starling Sturnus Vulgaris Serve A Mate Attraction Rather Than Insecticidal Function, Lucia Mariel Ibañez, Renato Andres García, Vanina Dafne Fiorini, Diego Montalti Jan 2018

Lichens In The Nests Of European Starling Sturnus Vulgaris Serve A Mate Attraction Rather Than Insecticidal Function, Lucia Mariel Ibañez, Renato Andres García, Vanina Dafne Fiorini, Diego Montalti

Turkish Journal of Zoology

The European starling Sturnus vulgaris is a hole-nesting bird in which the male builds a voluminous nest using a wide variety of materials such as twigs, grass, leaves, feathers, and lichens. The function of lichens in starling nests has not been assessed until now and we hypothesize that this material is related to a mate attraction function or is used to protect nestlings from parasites due to the presence of secondary compounds with insecticidal effects with the lichens. We aimed to identify the lichen species and frequency of lichen use in European starling nests, and to determine if the presence …

Dogs Aren’T Jealous – They Are Just Asking For Accurate Information, Karen L. Overall Jan 2018

Dogs Aren’T Jealous – They Are Just Asking For Accurate Information, Karen L. Overall

Animal Sentience

Awake fMRI offers us a unique opportunity to view and understand how dogs see the world and use the information in it. Given the limitations of behavioral assays and the small sample sizes inherent in these studies, labeling of patterns of canine behaviors using pop psychology terms may actually interfere with our understanding of canine brains and obscure for us a more parsimonious but exciting interpretation of canine behavior. We should use this window into how dogs think wisely.

Evidence For Extra-Gastric Expression Of The Proton Pump H+/K+ -Atpase In The Gills And Kidney Of The Teleost Oreochromis Niloticus, Ebtesam Barnawi Jan 2018

Evidence For Extra-Gastric Expression Of The Proton Pump H+/K+ -Atpase In The Gills And Kidney Of The Teleost Oreochromis Niloticus, Ebtesam Barnawi

Theses and Dissertations (Comprehensive)

It is well known that stomach acid secretion by oxynticopeptic cells of the gastric mucosa is accomplished by the H+/ K+-ATPase (HKA), which is comprised of the HKα1 (gene: atp4a) and HKβ (gene: atp4b) subunits. However, the role of the HKA in extra-gastric organs such as the gill and kidney is less clear especially in fishes. This pump may contribute to active ion and/or acid-base regulation either through direct ion transport or through secondary transport proteins against unfavorable concentration gradients via the energy derived from ATP hydrolysis. In the present work I have demonstrated …

Gill Structure & Function In Parasitic And Non-Parasitic Lampreys: The Effects Of Metamorphosis And Freshwater-Seawater Transfer, Julia Sunga Jan 2018

Gill Structure & Function In Parasitic And Non-Parasitic Lampreys: The Effects Of Metamorphosis And Freshwater-Seawater Transfer, Julia Sunga

Theses and Dissertations (Comprehensive)

Lamprey (Petromyzontiformes) are a phylogenetically ancient group of jawless fishes that begin their lives as filter-feeding larvae (ammocoetes) before undergoing a complex metamorphosis into juvenile lamprey that involves major changes to their internal and external body plan. Some parasitic species, such as the sea lamprey (Petromyzon marinus), migrate to sea following metamorphosis, where they use their oral discs and rasping tongue to attach to and ingest vast quantities of blood from fishes. Thus, sea lamprey have to counter the simultaneous challenges of hyposmoregulation in sea water and the generation of large quantities of ammonia due to the …

Can They Suffer?, Todd K. Shackelford Jan 2018

Can They Suffer?, Todd K. Shackelford

Animal Sentience

We should treat sentient nonhuman animals as worthy of moral consideration, not because we share an evolutionary history with them, but because they can suffer. As Chapman & Huffman (2018) argue, humans are not uniquely disconnected from other species. We should minimize the suffering we inflict on sentient beings — whether human or nonhuman — not because they, too, are tool-makers or have sophisticated communication systems, but because they, too, can suffer, and suffering is bad.

Two Fallacies In Comparisons Between Humans And Non-Humans, Don Ross Jan 2018

Two Fallacies In Comparisons Between Humans And Non-Humans, Don Ross

Animal Sentience

The hypothesis that humans are superior to non-humans by virtue of higher cognitive powers is often supported by two recurrent fallacies: (1) that any competence shown by humans but not by our closest living relatives (apes) must be unique to humans; and (2) that grades of intelligence can be inferred from behavior without regard to motivational structures.

Anthropocentrism As Cognitive Dissonance In Animal Research?, Ellen Furlong, Zachary Silver, Jack Furlong Jan 2018

Anthropocentrism As Cognitive Dissonance In Animal Research?, Ellen Furlong, Zachary Silver, Jack Furlong

Animal Sentience

Harmon-Jones et al. (2017) make a thought-provoking suggestion in their commentary on Zentall (2016): Overlooked biases among researchers on animal cognition might lead them to discount the traces of higher-order cognition in animals they study. We find the suggestion both philosophically important and worth further reflection for animal scientists. Harmon-Jones et al. point to two “cognitive dissonance” biases involving the clash between the common human resistance to viewing ourselves as animals/meat-eaters and how these biases might lead to discounting possible advanced cognitive performances in the animals studied. We show how these biases might appear in cognitive research generally and argue …

Forest Type Influences Population Densities Of Nocturnal Lemurs In Manompana, Northeastern Madagascar, Alex Miller, Harriet R. Mills, Tantely Ralantoharijaona, Nicole A. Volasoa, Chantal Misandeau, Lounès Chikhi, Roberta Bencini, Jordi Salmona Jan 2018

Forest Type Influences Population Densities Of Nocturnal Lemurs In Manompana, Northeastern Madagascar, Alex Miller, Harriet R. Mills, Tantely Ralantoharijaona, Nicole A. Volasoa, Chantal Misandeau, Lounès Chikhi, Roberta Bencini, Jordi Salmona

Research outputs 2014 to 2021

Forest loss, fragmentation, and anthropization threaten the survival of forest species all over the world. Shifting agriculture is one of these threatening processes in Madagascar. However, when its cycle is halted and the land is left to regenerate, the resulting growth of secondary forest may provide a viable habitat for folivorous and omnivorous lemur species. We aimed to identify the response of nocturnal lemurs to different successional stages of regenerating secondary, degraded mature, and mature forest across a mosaic-type landscape. We surveyed four nocturnal lemur species (Avahi laniger, Microcebus cf. simmonsi, Allocebus trichotis, and Daubentonia madagascariensis) in four forest types …

Fish Consciousness, David Gamez Jan 2018

Fish Consciousness, David Gamez

Animal Sentience

Woodruff makes two arguments to support his claim that ray-finned fish are conscious: (1) Fish neuroanatomy has similarities with the structures in the human brain that support consciousness. (2) The complexity and flexibility of fish behaviour suggest that they are conscious. This commentary will argue that neither the neuroanatomical nor the behavioural argument can provide conclusive evidence for consciousness in fish. We should suspend judgement until we have discovered mathematical theories of consciousness that can reliably map between states of consciousness and states of the physical world.

Fish Sentience Denial: Muddying The Waters, Lynne U. Sneddon, Javier Lopez-Luna, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Amanda D. Currie, Donald M. Broom, Culum Brown Jan 2018

Fish Sentience Denial: Muddying The Waters, Lynne U. Sneddon, Javier Lopez-Luna, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Amanda D. Currie, Donald M. Broom, Culum Brown

Animal Sentience

Recent empirical studies have reported evidence that many aquatic species, including fish, cephalopods and crustaceans, have the capacity for nociception and pain, and that their welfare should be taken into consideration. Some sceptics, rejecting the precautionary principle, have denied that any study demonstrates pain or other aspects of sentience in fish. This target article discusses some of the scientific shortcomings of these critiques through a detailed analysis of a study exploring nociception and analgesia in larval zebrafish.

Defining Pain And Painful Sentience In Animals, Edgar T. Walters Jan 2018

Defining Pain And Painful Sentience In Animals, Edgar T. Walters

Animal Sentience

Sentience is essential to most definitions of pain, including a detailed definition invoked by Sneddon et al. to argue that adult and perhaps larval fish feel pain. Because proving painful sentience in non-human animals is not feasible, multiple lines of indirect evidence are needed to implicate pain. This commentary examines the list of 17 criteria used by Sneddon et al. to conclude that fish have conscious pain. The criteria include tests of nociceptive, motivational, and cognitive properties useful for revealing pain-like states that can be understood biologically and be related evolutionarily to human pain. However, additional research is needed to …

Nocifensive Behavior As Evidence For Sentient Pain In Fish, Marissol Leite Da Silva, Caio Maximino, Diógenes Henrique Siqueira-Silva Jan 2018

Nocifensive Behavior As Evidence For Sentient Pain In Fish, Marissol Leite Da Silva, Caio Maximino, Diógenes Henrique Siqueira-Silva

Animal Sentience

Fish nocifensive behavior can be studied and understood similarly to the way pain is studied and understood in more advanced vertebrates. Nocifensive behavior is a behavioral and physiological response to a noxious stimulus that leads to the fish avoiding it in the future. This behavioral flexibility is an important criterion for inferring pain sentience in fish. Modulation of the nocifensive behavior by anxiety, fear, or stress has already been demonstrated in zebrafish. The affective experiences of fish will not be identical to those of human beings, clearly. Empirical research will need to ascertain how similar they are.

Fish Are Smart And Feel Pain: What About Joy?, Becca Franks, Jeff Sebo, Alexandra Horowitz Jan 2018

Fish Are Smart And Feel Pain: What About Joy?, Becca Franks, Jeff Sebo, Alexandra Horowitz

Animal Sentience

Sneddon et al. rightly point out that the evidence of fish pain is now so strong and comprehensive that arguments against it have become increasingly difficult to defend in balanced academic discourse. But sentience involves more than just pain. Recent research indicates that fish have an impressive range of cognitive capacities, including the capacity for pleasure, in the form of play and other behaviors likely to involve positively valenced experience. Having made the case for pain, research can now focus on other aspects of fish sentience. Doing so will not only provide a more complete picture of the mental lives …

Limits Of Neuroscience, Paul Morris Jan 2018

Limits Of Neuroscience, Paul Morris

Animal Sentience

Examining the relationship between jealous behaviour and the amygdala may be quite informative about the function of the amygdala, but the amygdala may be less helpful in informing us about jealous behaviour. Claims about the potential practical relevance of the results also require that the magnitude of the effects inform the relevant discussion. The dogs used in the study probably share some very important personality characteristics; this too limits the practical implications of Cook et al.’s findings for dogs in general. It is nevertheless a testament to the skill of the experimenters, and the amazing bond between dogs and humans, …

Defining Denial And Sentient Seafood, Jennifer Jacquet Jan 2018

Defining Denial And Sentient Seafood, Jennifer Jacquet

Animal Sentience

Sneddon et al. address the scientists who reject the empirical evidence on fish sentience, calling them “sceptics” and their work “denial”. This is the first article to frame the question of fish sentience in these terms, and it provides an obvious opening for social science and humanities research in the science of fish sentience. It is also worth asking what practical changes in the lives of fish might arise from the mounting evidence of their sentience. I suggest that the relationship between sentience and our sense of moral obligation is not as clear as we often assume.

Human And Nonhuman Animals: Equals In Uniqueness, Uta Maria Juergens Jan 2018

Human And Nonhuman Animals: Equals In Uniqueness, Uta Maria Juergens

Animal Sentience

Chapman & Huffman attack the idea that humans are unique and therefore superior to nonhuman beings. They call on humankind to use their “intellect to change [their] actions.” I am in full accord with their line of thought, which differentiates uniqueness from superiority and enjoins humans to take responsible action. I suggest, however, that humans are unique with regard to cognitive fluidity. The same conclusions can be reached via another argument based on human uniqueness.

Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson Jan 2018

Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson

Animal Sentience

Chapman & Huffman (2018) argue that we should not consider humans as unique or superior to other animals when we have the chance to explore the diversity of the traits of other species. This is a valid and progressive point in our approach to research, but I suggest that an anthropocentric approach can have animal welfare benefits when it helps us perceive other species – especially distantly related ones such as crustaceans – in a human light.

How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo Jan 2018

How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo

Animal Sentience

Chapman & Huffman (C & H) might be taken to argue as follows: Humans may treat animals however they want only if humans are superior to animals. But humans are not superior to animals. Therefore, humans may not treat animals however they want. Whatever its merit, this is not C & H’s actual argument. Their point, instead, is that humans often mistreat animals because they tend to perceive them as inferior. A remedy for animal mistreatment would then be acknowledging the deep similarities between us and animals. But is C & H’s suggested remedy likely to be effective to foster …

Insulting Words: "They Are Animals!", Carolyn A. Ristau Jan 2018

Insulting Words: "They Are Animals!", Carolyn A. Ristau

Animal Sentience

As Chapman & Huffman state, creating divisive human categories has rationalized atrocities committed against the “other.” Labeling neighboring warring villagers as “animals” is considered a despicable insult. Yet contemporary scientific views of many animals grant them thinking and conscious faculties, and the capacity for impressive achievements, many unattainable by humans. Robots, too, can accomplish many similar feats. But the essential reason we must protect animals is not because of their admirable abilities, but their capacity for consciousness, for suffering. Robots are not conscious. Participants in the human-animal debate should not complain about changing criteria for determining human uniqueness. New and …

Is Superiority A Necessary Aspect Of Cruelty?, William H. Edmondson Jan 2018

Is Superiority A Necessary Aspect Of Cruelty?, William H. Edmondson

Animal Sentience

Chapman & Huffman argue that humans inflict cruelty without apparent concern because of their categorization of the victims as inferior. The supposed inferiority of non-human animals can be argued against on the basis of documentation and analysis of behaviour. Humans continue to inflict cruelty on their own and other species. It is not obvious that a sense of superiority is a necessary aspect of cruel behaviour. Nor is it obvious that further enlightenment regarding the cognitive status of non-humans will diminish cruelty.
