An integrated approach to balance freshwater connectivity restoration and invasion risk

open access: yesConservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Relationships between synoptic-scale transport and interannual variability of inorganic cations in surface snow at Summit, Greenland: 1992-1996 [PDF]

open access: yes, 2001
To fully utilize the long-term chemical records retrieved from central Greenland ice cores, specific relationships between atmospheric circulation and the variability of chemical species in the records need to be better understood. This research examines

Postcolonial transitions on the southern borders of the former Soviet Union: the return of Eurasianism? [PDF]

open access: yes, 2003
As the Soviet Union dissolved into a new territorial reality, it released the doubly repressed histories of Tsarist and Soviet imperium. In the states to the south of the new Russian Federation, the post-soviet jostled with the postcolonial as nations ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

open access: yesEcological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

open access: yesEarly Medieval Europe, EarlyView.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

Genetic Diversity and Impacts of Stocking on Cyprinus carpio Populations in Türkiye: Insights From Mitochondrial, Nuclear, and Microsatellite Markers

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Understanding genetic diversity and population structure is essential for the sustainable management of widely stocked freshwater species such as common carp (Cyprinus carpio). In this study, we conducted a comprehensive genetic assessment of C.

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

open access: yesIbis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Modelling the national breeding distribution and population size of an elusive forest bird, the Eurasian Woodcock (Scolopax rusticola)

open access: yesIbis, EarlyView.
Understanding the distribution of species is central to conservation biology. Species distribution modelling (SDM) is a standard method used for this purpose, especially for elusive species for which limited occurrence data exist. The Eurasian Woodcock Scolopax rusticola (hereafter Woodcock) is an elusive, woodland‐dwelling wader that is declining in ...
