The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Effects of COVID-19 lockdowns on shorebird assemblages in an urban South African sandy beach ecosystem

open access: yesScientific Reports, 2022
Human pressures are pervasive in coastal ecosystems, but their effect magnitudes are masked by methodological limitations. Government lockdowns associated with the global COVID-19 pandemic can address this gap since lockdowns are effectively ...

A review of the biology and management of horseshoe crabs, with emphasis on Florida populations [PDF]

open access: yes, 2007
In Florida, some horseshoe crabs are fished for eel bait, but they are fished principally by the marine-life industry, which collects the animals live for resale as aquarium, research, or educational specimens.

Patterns and processes in shorebird survival rates: a global review [PDF]

open access: yes, 2018
Changes in demographic rates underpin changes in population size, and understanding demographic rates can greatly aid the design and development of strategies to maintain populations in the face of environmental changes.

Improving the use of expert opinion in disease risk analysis for conservation translocations

open access: yesConservation Biology, EarlyView.
Abstract Conservation translocations are subject to considerable uncertainty and risk, of which disease is one of the most recognized. To address disease risks, several protocols for qualitative disease risk analysis (qDRA) exist and are used for responsible conservation translocation planning.

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

open access: yesIbis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Physiological, morphological and behavioural responses of self-feeding precocial chicks copying with contrasting levels of water salinity during development [PDF]

open access: yes, 2016
Combined physiological and behavioural responses to salt loads during development have rarely been studied in air-breathing vertebrates able to inhabit hypersaline habitats, but they may be of particular importance in understanding, for example, the ...

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 ...

Relationships between chick vocalizations and parental absence in Kentish Plovers

open access: yesIbis, EarlyView.
Chick calls within bird species vary greatly, often in relation to whether parents are present. We studied chick calls in a nidifugous shorebird, the Kentish Plover Anarhynchus alexandrinus, in three circumstances—(1) on the nest with parental presence; (2) on the nest with parental absence; and (3) out‐of‐nest with human observer presence—and ...

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

open access: yesIbis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is
