First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

open access: yesJournal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Organizational Soundscapes and the Sonicity of Voices: The Power of the ‘Sounds’ that Carry ‘Words’

open access: yesJournal of Management Studies, EarlyView.
Abstract Organizations are soundscapes – they resonate with sounds and particularly the sounds of voices. Somehow however voice sonics, that is the sounds of voices and not the words carried on those sounds, have escaped attention in management studies. This absence of analysis is peculiar given voice sonics' undoubted influence on management (they may

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

open access: yesJournal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Introgression despite minimal hybridization: mating system modulates phenotypic associations with introgression in Clarkia

open access: yesNew Phytologist, EarlyView.
Summary Secondary contact between incipient species provides the opportunity to understand how trait divergence restricts gene flow. While mating system transitions are particularly common and involve a suite of phenotypic changes, the extent to which these changes influence gene flow during speciation is poorly understood.

Field trip stop descriptions [PDF]

open access: yes
Fifteen sites within the channeled scabland were selected as stops with the dual aim of visiting locations critical to the arguments for a catastrophic flood origin of the scablands, as well as permitting an examination of the variability in both ...

Effects of temperature on sexual competition in three kelp species, Pterygophora californica, Nereocystis luetkeana, and Macrocystis pyrifera: Implications for range shifts in foundation species

open access: yesPhycological Research, EarlyView.
SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

open access: yesRestoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...
