The Growth and N Retention of Two Annual Desert Plants Varied Under Different Nitrogen Deposition Rates.

Front Plant Sci 2019 26;10:356. Epub 2019 Mar 26.

Key Laboratory of Plant-Soil Interactions of the Ministry of Education, Beijing Key Laboratory of Farmland Soil Pollution Prevention and Remediation, College of Resources and Environmental Sciences, China Agricultural University, Beijing, China.

Nitrogen (N) partitioning between plant and soil pools is closely related to biomass accumulation and allocation, and is of great importance for quantifying the biomass dynamics and N fluxes of ecosystems, especially in low N-availability desert ecosystems. However, partitioning can differ among species even when growing in the same habitat. To better understand the variation of plant biomass allocation and N retention within ephemeral and annual species we studied the responses of (an ephemeral) and (an annual) to N addition, including plant growth, N retention by the plant and soil, and N lost to the environment using N (double-labeled NHNO (5.

Do topography and fruit presence influence occurrence and intensity of crop-raiding by forest elephants (Loxodonta africana cyclotis)?

PLoS One 2019 22;14(3):e0213971. Epub 2019 Mar 22.

TERRA Teaching and Research Centre, Forest Is Life, Gembloux Agro-Bio Tech, University of Liège, Gembloux, Belgium.

Crop damage by forest elephants (Loxodonta africana cyclotis) and the resulting human-elephant conflict are issues of great concern for both the conservation of the species and the protection of rural livelihoods in Central Africa. Addressing these problems requires identifying the factors that facilitate or impede crop-raiding by forest elephants. Yet to date, the environmental or anthropogenic factors that influence the occurrence and intensity of crop-raiding by forest elephants are largely unknown. Read More

A comparative perspective on the evolution of mammalian reactions to dead conspecifics.

Primates 2019 Mar 20. Epub 2019 Mar 20.

Save The Giraffes, San Antonio, TX, USA.

In a variety of mammalian species, mothers and others care for and/or carry deceased newborns, and sometimes other conspecifics. The rationale for such behavior remains elusive. Based upon field observations of olive baboon (Papio anubis), African elephant (Loxodonta africana), and Thornicroft's giraffe (Giraffa camelopardalis) responses to recently dead conspecifics, combined with reports in the literature, a hypothesis is proposed to account for this activity.

War-induced collapse and asymmetric recovery of large-mammal populations in Gorongosa National Park, Mozambique.

PLoS One 2019 13;14(3):e0212864. Epub 2019 Mar 13.

Department of Ecology & Evolutionary Biology, Princeton University, Princeton, NJ, United States of America.

How do large-mammal communities reassemble after being pushed to the brink of extinction? Few data are available to answer this question, as it is rarely possible to document both the decline and recovery of wildlife populations. Here we present the first in-depth quantitative account of war-induced collapse and postwar recovery in a diverse assemblage of large herbivores. In Mozambique's Gorongosa National Park, we assembled data from 15 aerial wildlife counts conducted before (1968-1972) and after (1994-2018) the Mozambican Civil War (1977-1992). Read More

Biol Reprod 2019 Mar 8. Epub 2019 Mar 8.

Center for Species Survival, Smithsonian Conservation Biology Institute, Front Royal, VA.

Many zoo elephants do not cycle normally, and for African elephants, it often is associated with hyperprolactinemia. Dopamine agonists successfully treat hyperprolactinemia-induced ovarian dysfunction in women, but not elephants. The objective of this study was to determine how longitudinal dopamine, serotonin and oxytocin patterns in African elephants are related to ovarian cycle function. Read More

Determinants of elephant foraging behaviour in a coupled human-natural system: Is brown the new green?

J Anim Ecol 2019 Mar 2. Epub 2019 Mar 2.

Department of Fish and Wildlife Sciences, University of Idaho, Moscow, Idaho.

Crop raiding by wildlife poses major threats to both wildlife conservation and human well-being in agroecosystems worldwide. These threats are particularly acute in many parts of Africa, where crop raiders include globally threatened megafauna such as elephants, and where smallholder agriculture is a primary source of human livelihood. One framework for understanding herbivore feeding behaviour, the forage-maturation hypothesis, predicts that herbivores should align their movements with intermediate forage biomass (i. Read More

Front Vet Sci 2019 6;6:18. Epub 2019 Feb 6.

Division of Molecular Biology and Human Genetics, Faculty of Medicine and Health Sciences, DST-NRF Centre of Excellence for Biomedical Tuberculosis Research, South African Medical Research Council Centre for TB Research, Stellenbosch University, Cape Town, South Africa.

Tuberculosis (TB) in humans is a global public health concern and the discovery of animal cases of (Mtb) infection and disease, especially in multi-host settings, also has significant implications for public health, veterinary disease control, and conservation endeavors. This paper describes a fatal case of Mtb disease in a free-ranging African elephant () in a high human TB burden region. Necropsy revealed extensive granulomatous pneumonia, from which Mtb was isolated and identified as a member of LAM3/F11 lineage; a common lineage found in humans in South Africa. Read More

Mammoth ivory was the most suitable osseous raw material for the production of Late Pleistocene big game projectile points.

Sci Rep 2019 Feb 19;9(1):2303. Epub 2019 Feb 19.

Friedrich Schiller University Jena, Otto Schott Institute of Materials Research, Löbdergraben 32, D-07743, Jena, Germany.

Late Pleistocene societies throughout the northern hemisphere used mammoth and mastodon ivory not only for art and adornment, but also for tools, in particular projectile points. A comparative analysis of the mechanical properties of tusk dentine from woolly mammoth (Mammuthus primigenius) and African elephant (Loxodonta africana) reveals similar longitudinal stiffness values that are comparable to those of cervid antler compacta. The longitudinal bending strength and work of fracture of proboscidean ivory are very high owing to its substantial collagen content and specific microstructure. Read More

Diversification and speciation in tree frogs from the Maghreb (Hyla meridionalis sensu lato), with description of a new African endemic.

Mol Phylogenet Evol 2019 May 15;134:291-299. Epub 2019 Feb 15.

Institute of Cytology, Russian Academy of Sciences, Saint Petersburg, Russia; Dagestan State University, Makhachkala, Russia.

Comparative molecular studies emphasized a new biogeographic paradigm for the terrestrial fauna of North Africa, one of the last uncharted ecoregions of the Western Palearctic: two independent east-west divisions across the Maghreb. Through a comprehensive phylogeography, we assessed how this model suits the genetic diversification documented for the tree frog Hyla meridionalis sensu lato. Analyses of mtDNA variation and thousands of nuclear loci confirmed the old split (low-Pliocene) between Tunisian and Algerian populations. Read More

Terrestrial mammalian wildlife responses to Unmanned Aerial Systems approaches.

Sci Rep 2019 Feb 14;9(1):2142. Epub 2019 Feb 14.

Structure and Motion Laboratory, Royal Veterinary College, University of London, London, United Kingdom.

Unmanned Aerial Systems (UAS) are increasingly being used recreationally, commercially and for wildlife research, but very few studies have quantified terrestrial mammalian reactions to UAS approaches. We used two Vertical Take-off and Landing (VTOL) UAS to approach seven herbivore species in the Moremi Game Reserve, Botswana, after securing the relevant permissions. We recorded responses to 103 vertical and 120 horizontal approaches, the latter from three altitudes above ground level (AGL). Read More

Explaining different orientations to the 2013 Gezi Park demonstrations in Istanbul, Turkey.

Br J Soc Psychol 2019 Feb 11. Epub 2019 Feb 11.

Department of Psychological Sciences, University of Connecticut, Storrs, Connecticut.

Although a notable minority orient to real-world demonstrations by actively participating, other less involved, safer, orientations are more frequent. Thus, in the context of anti-government demonstrations in Gezi Park/Taksim Square in Istanbul, Turkey, in 2013, we distinguished between the orientations of participating, visiting, and watching. Study 1 (N = 359) and Study 2 (N = 327) confirmed that participating was characterized by greater experience of police violence and feelings of collective empowerment (Drury & Reicher, European Journal of Social Psychology, 35, 2005, 35) than visiting and watching the demonstrations.

African savanna elephants () as an example of a herbivore making movement choices based on nutritional needs.

PeerJ 2019 1;7:e6260. Epub 2019 Feb 1.

Inorganic Geochemistry, Centre for Environmental Geochemistry, British Geological Survey, Nottingham, UK.

Background: The increasing human population and global intensification of agriculture have had a major impact on the world's natural ecosystems and caused devastating effects on populations of mega-herbivores such as the African savanna elephants, through habitat reduction and fragmentation and increased human-animal conflict. Animals with vast home ranges are forced into increasingly smaller geographical areas, often restricted by fencing or encroaching anthropogenic activities, resulting in huge pressures on these areas to meet the animals' resource needs. This can present a nutritional challenge and cause animals to adapt their movement patterns to meet their dietary needs for specific minerals, potentially causing human-animal conflict. Read More

Arcuate foramen: "Anatomical variation shape or adaptation legacy?"

Surg Radiol Anat 2019 Jan 17. Epub 2019 Jan 17.

Department of Neurosurgery, Bretonneau University Hospital, Tonnellé Boulevard 2, Tours, France.

Purpose: The groove of the vertebral artery on the posterior arch of the atlas (sulcus arteriae vertebralis) may become a complete or partial osseous foramen: the arcuate foramen. The presence of a complete or partial arcuate foramen is a rare anatomical variant described in a minority of patients and it seems to be associated with vertigo, vertebro-basilar insufficiency, posterior circulation strokes, and musculoskeletal pain. As the number and morphology of cervical vertebrae is highly preserved, we questioned about its significance from an evolutionary point of view. Read More

Faculty of Agriculture and Environmental Science Bindura University of Science Education Bindura Zimbabwe.

The ways in which spines and thorns on plants affect browsing behavior and instantaneous intake rate (IIR) have been investigated for several medium and large ungulates, with most authors concluding that spines either affect the ability to obtain a full bite, or prevent the removal of twig material. We investigated how a very small ruminant, the blue duiker (; mass 5 kg), altered its feeding strategy when confronted with intact or despined branches of three species of woody plant that differed in leaf and spine size, density, and arrangement, viz. and .

Farmers' preferred tree species and their potential carbon stocks in southern Burkina Faso: Implications for biocarbon initiatives.

PLoS One 2018 18;13(12):e0199488. Epub 2018 Dec 18.

Université du Faso (UFA), Ouagadougou, Burkina Faso.

The success of terrestrial carbon sequestration projects for rural development in sub-Saharan Africa lies in the (i) involvement of local populations in the selection of woody species, which represent the biological assets they use to meet their daily needs, and (ii) information about the potential of these species to store carbon. Although the latter is a key prerequisite, there is very little information available. To help fill this gap, the present study was undertaken in four pilot villages (Kou, Dao, Vrassan and Cassou) in Ziro Province, south-central Burkina Faso. Read More

Keeping us all whole: Acknowledging the agency of African American breast cancer survivors and their systems of social support.

Support Care Cancer 2018 Nov 23. Epub 2018 Nov 23.

Walden University, Minneapolis, MN, USA.

While all cancer patients face a bewildering array of treatments, side effects, and emotions, several researchers have shown that African American women with breast cancer experience greater stress and burdens because of unmet supportive needs associated with psychological distress, financial distress, and lower physical/functional well-being. Social support has been shown to improve health outcomes for African American breast cancer patients. The purpose of this paper is to understand the meaning of social support among African American women diagnosed with breast cancer. Read More

Human Exposure to Novel Bartonella Species from Contact with Fruit Bats.

Emerg Infect Dis 2018 12;24(12):2317-2323

Twice a year in southwestern Nigeria, during a traditional bat festival, community participants enter designated caves to capture bats, which are then consumed for food or traded. We investigated the presence of Bartonella species in Egyptian fruit bats (Rousettus aegyptiacus) and bat flies (Eucampsipoda africana) from these caves and assessed whether Bartonella infections had occurred in persons from the surrounding communities. Our results indicate that these bats and flies harbor Bartonella strains, which multilocus sequence typing indicated probably represent a novel Bartonella species, proposed as Bartonella rousetti.

Nat Commun 2018 10 2;9(1):3865. Epub 2018 Oct 2.

Laboratory of Artificial & Natural Evolution (LANE), Department of Genetics & Evolution, University of Geneva, Geneva, 1211, Switzerland.

An intricate network of crevices adorns the skin surface of the African bush elephant, Loxodonta africana. These micrometre-wide channels enhance the effectiveness of thermal regulation (by water retention) as well as protection against parasites and intense solar radiation (by mud adherence). While the adaptive value of these structures is well established, their morphological characterisation and generative mechanism are unknown. Read More
