Colonial-era settlements and post-colonial legacies have increased the loss of montane forests in the central highlands of Kenya

Communications Earth & Environment
Long-term historical studies of montane tropical forest loss in eastern Africa have been relatively neglected compared to other world regions, despite ramifications for biodiversity, climate crises, and knock-on effects on the African continent. Moreover,

Beyond the specimen: rethinking ornithological collecting in a changing world

Ibis, EarlyView.
Natural history collections underpin a wide range of ornithological research, yet the context in which they operate is rapidly changing. Advances in genomics, digitization and analytical approaches are transforming what can be learned from specimens, while accelerating environmental change is increasing the need for temporally explicit, integrative ...

A synthesis of coevolution across levels of biological organization.

In evolutionary ecology, coevolution is typically defined as reciprocal evolution of interacting species. However, outside the context of interacting species, the term "coevolution" is also used at levels of biological organization within species (e.g ...

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

3‐D Modeling of Differential Exhumation of Ultrahigh‐Pressure Metamorphic Rocks Driven by Increasing Plate Divergence

Geochemistry, Geophysics, Geosystems
Petrological and seismic constraints suggest differential sampling depth for ultrahigh pressure (UHP) metamorphic rocks exposed in different segments of the fossil subduction zone of the Western Alps. However, the mechanisms for the observed differential

Disruption of OsMAPKKK24 activation by the Xanthomonas oryzae effector XopY leads to compromised disease resistance in rice

Journal of Integrative Plant Biology, EarlyView.
The kinase OsRLCK55 phosphorylates OsMAPKKK24 to positively regulate rice resistance against Xanthomonas oryzae. To compromise this defense, the effector XopY targets OsMAPKKK24 and suppresses its autophosphorylation and the transphosphorylation mediated by OsRLCK55, ultimately leading to reduced disease resistance.

Basal mantle structure regenerated through supercontinents

Nature Communications
The African large low shearwave-velocity province (LLSVP) advected plumes manifest as large igneous provinces (LIPs) during Pangea breakup. The existence of such basal mantle structures during earlier supercontinents is unknown.

No Cocoa Without Deforestation? A Field‐Type Analysis of Forest Frontiers in West Africa

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper analyses the interrelations of production systems, class relations and deforestation in a smallholder forest frontier. Using the concept of field types, we provide a plot‐level analysis of deforestation processes in West Africa, where smallholders convert forest into cocoa farms.

Coevolution in Evolutionary Circuit Design

, 2016
This thesis deals with evolutionary design of the digital circuits performed by a cartesian genetic programing and optimization by a coevolution. Algorithm coevolves fitness predictors that are optimized for a population of candidate digital circuits ...

Bridging Knowledge Capability Gaps: Digital Technology Offsetting in Interfirm Knowledge Transfer

Journal of Management Studies, EarlyView.
Abstract In this digital age, the adoption of digital technology (DT) is changing traditional business processes. Against this backdrop, we try to answer the question of whether DT could effectively bridge any interfirm knowledge capability gaps. Though effective knowledge transfer is dependent on the sender's and the receiver's knowledge capabilities,
