Fishing and environmental change during the emergence of social complexity in the Lake Titicaca Basin

José M. Capriles, Katherine M. Moore, Alejandra I. Domic, Christine A. Hastorf, more

Journal of Anthropological Archaeology > 2014 > 34 > Complete > 66-77

The Lake Titicaca Basin is one of the regions in the world where both primary village and state formation occurred in prehistory. Although agriculture has been discussed as the central engine fueling these processes, fish and other aquatic resources were significant but little-understood components of the region’s ancient economy. In this paper, we use zooarchaeological analysis of faunal remains...

The impact of the abrupt 8.2 ka cold event on the Mesolithic population of western Scotland: a Bayesian chronological analysis using ‘activity events’ as a population proxy

Karen Wicks, Steven Mithen, K. Wicks, S. Mithen

Journal of Archaeological Science > 2014 > 45 > Complete > 240-269

The potential impact of the abrupt 8.2 ka cold event on human demography, settlement patterns and culture in Europe and the Near East has emerged as a key theme in current discussion and debate. We test whether this event had an impact on the Mesolithic population of western Scotland, a case study located within the North Atlantic region where the environmental impact of the 8.2 ka event is likely...

Divergent response and adaptation of specific leaf area to environmental change at different spatio‐temporal scales jointly improve plant survival

Zhaogang Liu, Ming Zhao, Hongxiang Zhang, Tingting Ren, more

Global Change Biology > 29 > 4 > 1144 - 1159

Specific leaf area (SLA) is one of the most important plant functional traits. It integrates multiple functions and reflects strategies of plants to obtain resources. How plants employ different strategies (e.g., through SLA) to respond to dynamic environmental conditions remains poorly understood. This study aimed to explore the spatial variation in SLA and its divergent adaptation through the lens...

Three perspectives on the prediction of chemical effects in ecosystems

Anke Schneeweiss, Noël P. D. Juvigny‐Khenafou, Stephen Osakpolor, Andreas Scharmüller, more

Global Change Biology > 29 > 1 > 21 - 40

The increasing production, use and emission of synthetic chemicals into the environment represents a major driver of global change. The large number of synthetic chemicals, limited knowledge on exposure patterns and effects in organisms and their interaction with other global change drivers hamper the prediction of effects in ecosystems. However, recent advances in biomolecular and computational methods...

Empirical test of increasing genetic variation via inter‐population crossing for native plant restoration in variable environments

April M. Goebl, Daniel F. Doak, Nolan C. Kane

Restoration Ecology > 30 > 8 > n/a - n/a

Restoring native plant populations is an essential component of conserving biodiversity, ecological function, and ecosystem services. Restoration using local, ecotypic source materials is largely acknowledged as best practice; however, local populations are not always available or adapted to current or future site conditions. A major challenge in restoration comes from increasingly variable and unpredictable...

Predicting spatio‐temporal population patterns of Borrelia burgdorferi, the Lyme disease pathogen

Tam Tran, Melissa A. Prusinski, Jennifer L. White, Richard C. Falco, more

Journal of Applied Ecology > 59 > 11 > 2779 - 2789

The causative bacterium of Lyme disease, Borrelia burgdorferi, expanded from an undetected human pathogen into the etiologic agent of the most common vector‐borne disease in the United States over the last several decades. Systematic field collections of the tick vector reveal increases in the geographic range and prevalence of B. burgdorferi–infected ticks that coincided with increases in human...

Morphological disparity trends in Devonian trilobites from North Africa

Valentin Bault, Catherine Crônier, Claude Monnet, Javier Álvaro

Palaeontology > 65 > 5 > n/a - n/a

The Devonian was a time of drastic environmental change that shaped the morphology of trilobites. This study aims to investigate their morphological evolution and to show the influence of some abiotic and biotic factors (bathymetry, feeding habits and visual abilities) on their shape. A dataset was compiled to investigate the shape of three structures (cephalon as a whole, central part of the cephalon,...

Gas compressor noise does not influence tree swallow nestling condition or immune response

K. J. MacLeod, L. Naugle, M. C. Brittingham, J. D. Avery

Journal of Zoology > 318 > 1 > 1 - 9

Anthropogenic noise pollution, such as that derived from traffic and industrial machinery, has been identified as an urgent conservation priority as it is often louder and more prevalent than natural acoustic stimuli, and can act as a stressor on wildlife. Research in avian systems has shown that anthropogenic noise can affect physiology and reproductive success of adult birds – but effects on juvenile...

The Effect of Discontinuous and Unpredictable Environmental Change on Management Accounting During Organizational Crisis: A Field Study*

Christie Hayne

Contemporary Accounting Research > 39 > 3 > 1758 - 1796

This study investigates whether and how organizations change their use of management accounting during crisis. The study is important because organizations regularly face significant challenges such as crisis during which the role of management accounting is not well understood. Based on interviews and observation in five private sector organizations and one in the public sector, I find that executives...

Sediment sources and transport dynamics in large, regulated river systems with multiple lakes and reservoirs in the subarctic region of Canada

Masoud Goharrokhi, Gregory K. McCullough, David A. Lobb, Philip N. Owens, more

Hydrological Processes > 36 > 9 > n/a - n/a

The Burntwood River (BR) and Upper Nelson River (UNR) are regulated rivers in the subarctic region of Canada. They merge at Split Lake and then discharge into Hudson Bay via the Lower Nelson River (LNR). The BR water discharge was increased eight‐fold by a cross‐watershed diversion in 1976. The UNR drains the 11^th largest lake in the world, Lake Winnipeg, which itself receives discharge from a large...

Linking bifurcation analysis of Holling–Tanner model with generalist predator to a changing environment

Chuang Xiang, Jicai Huang, Hao Wang

Studies in Applied Mathematics > 149 > 1 > 124 - 163

Bifurcation theory has been highly popular in the analysis of mathematical models. However, stability and bifurcation analyses are only for asymptotic dynamics while applied scientists care more about transient dynamics. In this paper, we first rigorously analyze Holling–Tanner model with generalist predators who have alternative food sources, and then discuss transient dynamics via a changing environment...

Frontiers in quantifying wildlife behavioural responses to chemical pollution

Michael G. Bertram, Jake M. Martin, Erin S. McCallum, Lesley A. Alton, more

Biological Reviews > 97 > 4 > 1346 - 1364

Animal behaviour is remarkably sensitive to disruption by chemical pollution, with widespread implications for ecological and evolutionary processes in contaminated wildlife populations. However, conventional approaches applied to study the impacts of chemical pollutants on wildlife behaviour seldom address the complexity of natural environments in which contamination occurs. The aim of this review...

How thermal challenges change gene regulation in the songbird brain and gonad: Implications for sexual selection in our changing world

Sara E. Lipshutz, Clara R. Howell, Aaron M. Buechlein, Douglas B. Rusch, more

Molecular Ecology > 31 > 13 > 3613 - 3626

In a rapidly warming world, exposure to high temperatures may impact fitness, but the gene regulatory mechanisms that link sublethal heat to sexually selected traits are not well understood, particularly in endothermic animals. Our experiment used zebra finches (Taeniopygia guttata), songbirds that experience extreme temperature fluctuations in their native Australia. We exposed captive males to an...

State‐dependent environmental sensitivity of reproductive success and survival in a shorebird

Jurrian Irsel, Magali Frauendorf, Bruno J. Ens, Martijn Pol, more

Ibis > 164 > 3 > 692 - 710

To understand the consequences of anthropogenic and environmental changes for wildlife populations, it is important to study how individuals differ in their sensitivity to environmental change and whether this depends on individual characteristics. An individual's reproductive performance may provide an integrative, unidimensional proxy of an individual's characteristics. In this study, we define...

Genomic reaction norms inform predictions of plastic and adaptive responses to climate change

Rebekah A. Oomen, Jeffrey A. Hutchings

Journal of Animal Ecology > 91 > 6 > 1073 - 1087

Genomic reaction norms represent the range of gene expression phenotypes (usually mRNA transcript levels) expressed by a genotype along an environmental gradient. Reaction norms derived from common‐garden experiments are powerful approaches for disentangling plastic and adaptive responses to environmental change in natural populations. By treating gene expression as a phenotype in itself, genomic...

Evaluation of Shell Powder Remediation Effect in Cadmium‐Contaminated Soil: A Score Approach Based on Entropy Indexes

Haodong Zhao, Liyu Du, Tingting An, Yan Wu, more

CLEAN – Soil, Air, Water > 50 > 5 > n/a - n/a

A highly effective, economical, and replicable way is imperative to remediate Cadmium (Cd)‐polluted soil. Shell powder is sometimes used to remediate soil contaminated with potentially toxic metals. However, information is limited regarding shell powder assessment. Shell powder is thermally modified at 400, 600, and 800 °C and is added to Cd‐polluted soil for 50 days. The repair effects of shell powder...

Environmental filtering drives assembly of diatom communities over evolutionary time‐scales

Elena Jovanovska, Torsten Hauffe, Björn Stelbrink, Aleksandra Cvetkoska, more

Global Ecology and Biogeography > 31 > 5 > 954 - 967

Aim Ecological communities are structured through the interplay of deterministic assembly processes such as competition and environmental filtering. Whereas the drivers of spatial community structure are frequently studied in extant communities, little is known about the relative importance of assembly processes in response to environmental factors over evolutionary time‐scales. Here, we use an integrative...

Parasite dynamics in North American monarchs predicted by host density and seasonal migratory culling

Ania A. Majewska, Andrew K. Davis, Sonia Altizer, Jacobus C. Roode

Journal of Animal Ecology > 91 > 4 > 780 - 793

Insect–pathogen dynamics can show seasonal and inter‐annual variations that covary with fluctuations in insect abundance and climate. Long‐term analyses are especially needed to track parasite dynamics in migratory insects, in part because their vast habitat ranges and high mobility might dampen local effects of density and climate on infection prevalence. Monarch butterflies Danaus plexippus...

Functional traits explain the consistent resistance of biodiversity to plant invasion under nitrogen enrichment

Shao‐peng Li, Pu Jia, Shu‐ya Fan, Yingtong Wu, more

Ecology Letters > 25 > 4 > 778 - 789

Elton's biotic resistance hypothesis, which posits that diverse communities should be more resistant to biological invasions, has received considerable experimental support. However, it remains unclear whether such a negative diversity–invasibility relationship would persist under anthropogenic environmental change. By using the common ragweed (Ambrosia artemisiifolia) as a model invader, our 4‐year...
