Astatotilapia species (Teleostei, Cichlidae) from Malawi, Mozambique and Tanzania, excluding the basin of Lake Victoria.

George Turner, Benjamin P Ngatunga, Martin J Genner

Published: 2021-04-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

The haplochromine cichlid fauna of the rivers and smaller lakes of Tanzania and SE Africa are of key importance in understanding the origins and inter-relationships of the great lake cichlid radiations of Malawi, Tanganyika and Victoria. Prior to formal taxonomic investigations, here we present the results of investigations of the type specimens, identification of type localities and superficial [...]

Supporting actionable science for environmental policy: Advice for funding agencies from decision makers

Elizabeth A Nyboer, Vivian Nguyen, Nathan Young, et al.

Published: 2021-04-02
Subjects: Environmental Policy, Environmental Studies, Life Sciences, Public Affairs, Public Policy and Public Administration, Social and Behavioral Sciences

Successful incorporation of scientific knowledge into environmental policy and decisions is a significant challenge. Although studies on how to bridge the knowledge-action gap have grown rapidly over the last decade, few have investigated the roles, responsibilities, and opportunities for funding bodies to meet this challenge. In this study we present a set of criteria gleaned from interviews [...]

Applying the FEW nexus concept at the local scale

Henry P. Huntington, Jennifer Schmidt, Philip A. Loring, et al.

Published: 2021-04-02
Subjects: Civil and Environmental Engineering, Engineering, Environmental Studies, Social and Behavioral Sciences

The food-energy-water (FEW) nexus describes interactions among domains that yield gains or tradeoffs when analyzed together rather than independently. In a project about renewable energy in rural Alaska communities, we applied this concept to examine the implications for sustainability and resilience. The FEW nexus provided a useful framework for identifying the cross-domain benefits of renewable [...]

Contrasting climate velocity impacts in warm and cool locations show that effects of marine warming are worse in already warmer temperate waters

Philina English, Eric J. Ward, Christopher N. Rooper, et al.

Published: 2021-04-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Population Biology, Terrestrial and Aquatic Ecology

Species responses to climate change are often measured at broad spatiotemporal scales, which can miss fine-scale changes that are relevant to conservation and fisheries management. We develop a scale-able geostatistical approach to assess how juvenile and adult fish distributions have been shaped by changes in bottom temperature and dissolved oxygen over a recent decade of warming in the [...]

Forest Conservation in Madagascar: Past, Present, Future

Julia P G Jones, Sarobidy Rakotonarivo, Julie Hanta Razafimanahaka

Published: 2021-04-01
Subjects: Biodiversity, Life Sciences

To be published in the upcoming book The New Natural History of Madagascar, edited by S. M. Goodman, published by Princeton University Press. A French translation of the chapter "Conservation des forêts à Madagascar : Passé, Présent, et Futur" is included at the end of the preprint. At this critical time for the future of Madagascar’s biodiversity, we first review the past: touching upon [...]

Global economic and diet transitions drove Latin American and Caribbean forest change during the first decade of the century.

David Lopez-Carr, Sadie Jane Ryan, Matthew Clark

Published: 2021-04-01
Subjects: Arts and Humanities, Environmental Sciences, Geography, Life Sciences, Natural Resources and Conservation, Physical and Environmental Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences

Latin America and the Caribbean (LAC) contain more tropical high-biodiversity forest than the remaining areas of the planet combined, yet experienced more than a third of global deforestation during the first decade of the 21st century. While drivers of forest change occur at multiple scales, we examined forest change at the municipal and national scales integrated with global processes such as [...]

Hutchinsons ecological niche for individuals

Elina Takola, Holger Schielzeth

Published: 2021-04-01
Subjects: Animal Studies, Environmental Studies, Social and Behavioral Sciences

We here develop a concept of an individualized niche in analogy to Hutchison’s population-level concept of the ecological niche. We consider the individualized (ecological) niche as the range of environmental conditions under which a particular individual has expected lifetime reproductive success of ≥1. Our concept is essentially ecological primarily in the sense of fit of individual phenotypes [...]

Oropendola nest predation and rodent consumption by the black-capped capuchin (Sapajus apella) in the Manu Biosphere Reserve, Peru

Andrew Lee, Michelle Huang

Published: 2021-03-27
Subjects: Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics

The Neotropical primate Sapajus apella (Linnaeus, 1758), the black-capped capuchin monkey, is widely distributed across the Amazon basin (Boubli et al., 2020). Capuchins are generalist platyrrhines, occurring in most tropical forest types, where they forage opportunistically (Sabbatini et al., 2008; Lynch Alfaro et al., 2012; Boubli et al., 2020). They exploit a diverse variety of food sources, [...]

Weak but persistent provenance effects modulate the response of Quercus robur (Fagaceae) seedlings to elevated temperature

Sumitra Dewan, Pieter De Frenne, Sebastian Kepfer-Rojas, et al.

Published: 2021-03-26
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Background and aims Clinal variation in bud phenology and growth has repeatedly been reported in common garden experiments for many tree species. The response of the seedlings generated from such translocated trees has not been studied yet, despite its relevance regarding the role of transgenerational plasticity in the adaptation of long-living trees in the face of climate change. Here, we aim to [...]

Effects of wave-driven water flow on the fast-start escape response of juvenile coral reef damselfishes

Dominique Roche

Published: 2021-03-26
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences

Fish often evade predators with a fast-start escape response. Studies typically examine this behaviour in still water despite water motion being an inherent feature of aquatic ecosystems. In shallow habitats, waves create complex flows that likely influence escape performance, particularly in small fishes with low absolute swimming speeds relative to environmental flows. I examined how [...]

Applying conservation reserve design strategies to define ecosystem monitoring priorities

Irene Martín-Forés, Greg Guerin, Samantha Munroe, et al.

Published: 2021-03-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

In an era of unprecedented ecological upheaval, accurately monitoring ecosystem change at large spatial scales and over long-time frames is an essential to effective environmental management and conservation. However, economic limitations often preclude revisiting entire monitoring networks at a high enough frequency to accurately detect ecological changes. Thus, a prioritisation strategy is [...]

Early predation risk shapes adult learning and cognitive flexibility

Catarina Vila-Pouca, David Joseph Mitchell, Jérémy Lefèvre, et al.

Published: 2021-03-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Predation risk during early ontogeny can impact developmental trajectories and permanently alter adult phenotypes. Such phenotypic plasticity often leads to adaptive changes in traits involved in anti-predator responses. While plastic changes in cognition may increase survival, it remains unclear whether early predation experience shapes cognitive investment and drives developmental plasticity in [...]

Report of programming bugs in the DAISIE R package: consequences and correction

Luis Valente, Nadiah Kristensen, Albert Phillimore, et al.

Published: 2021-03-24
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences

DAISIE (Dynamic Assembly of Islands through Speciation, Immigration and Extinction) is a framework for a dynamic stochastic model of island biogeography that can be used to estimate the rates of colonisation, speciation and extinction (CES rates) from phylogenetic trees of insular communities by maximum likelihood, and to simulate such data sets given a set of rates. The framework is available in [...]

Novel phylogenetic methods reveal that resource-use intensification drives the evolution of “complex” societies

Erik Ringen, Jordan Scott Martin, Adrian Jaeggi

Published: 2021-03-24
Subjects: Anthropology, Other Anthropology, Social and Behavioral Sciences

Explaining the rise of large, sedentary populations, with attendant expansions of socio-political hierarchy and labor specialization (collectively referred to as “societal complexity”), is a central problem for social scientists and historians. Adoption of agriculture has often been invoked to explain the rise of complex societies, but archaeological and ethnographic records contradict simple [...]

Effects of male and female personality on sexual cannibalism in the Springbok mantis

Pietro Pollo, Nathan W Burke, Gregory I Holwell

Published: 2021-03-24
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Behaviours that are consistent across contexts (also known as behavioural syndromes) can have evolutionary implications, but their role in scenarios where the sexes conflict, such as sexual cannibalism, is poorly understood. The aggressive spillover hypothesis proposes that cannibalistic attacks during adulthood may depend on female aggressiveness during earlier developmental stages, but evidence [...]
