Timing Manipulations Reveal the Lack of a Causal Link Across Timing of Annual-Cycle Stages in a Long-Distance Migrant Barbara M

Published by The Company of Biologists Ltd | Journal of Experimental Biology (2019) 222, jeb201467. doi:10.1242/jeb.201467 RESEARCH ARTICLE Timing manipulations reveal the lack of a causal link across timing of annual-cycle stages in a long-distance migrant Barbara M. Tomotani1,2,*, Iván de la Hera1,3, Cynthia Y. M. J. G. Lange1, Bart van Lith1, Simone L. Meddle4, Christiaan Both5 and Marcel E. Visser1,5 ABSTRACT and Wingfield, 2000; Wingfield, 2008). Annual cycles vary in Organisms need to time their annual-cycle stages, like breeding and complexity in a species-specific way: from simple breeding/non- migration, to occur at the right time of the year. Climate change has breeding transitions to the inclusion of other energetically demanding shifted the timing of annual-cycle stages at different rates, thereby stages like migration or moult (Wingfield, 2008). As the total time tightening or lifting time constraints of these annual-cycle stages, a available for the allocation of these seasonal stages is 1 year, more rarely studied consequence of climate change. The degree to which complex annual cycles will necessarily involve a concomitant increase these constraints are affected by climate change depends on whether in time constraints. This is especially true if these different stages are consecutive stages are causally linked (scenario I) or whether the all energetically demanding and need to be temporally segregated timing of each stage is independent of other stages (scenario II). (Dietz et al., 2013). Complex annual cycles would thus result in low Under scenario I, a change in timing in one stage has knock-on timing flexibility as further shortening or overlapping stages would lead to effects on subsequent stages, whereas under scenario II, a shift in the fitness costs (Jacobs and Wingfield, 2000; Wingfield, 2008). -

ISSN 1065-9366 (print), 2168-3158 (online) Abstract When Carr traveled to the Middle East, he observed the local birds. In this article, he suggests the possi- bility that the Book of Mormon prophet Lehi and his family relied on birds for food and for locating water. Carr discusses the various birds that Lehi’s family may have seen on their journey and the Mosaic law per- taining to those birds.

DNA Barcode Reference Library for Iberian Butterflies
www.nature.com/scientificreports OPEN DNA barcode reference library for Iberian butterflies enables a continental-scale preview of Received: 11 January 2015 Accepted: 11 May 2015 potential cryptic diversity Published: 24 July 2015 Vlad Dincă1,2, Sergio Montagud3, Gerard Talavera1,4,5, Juan Hernández-Roldán6, Miguel L. Munguira6, Enrique García-Barros6, Paul D. N. Hebert2 & Roger Vila1 How common are cryptic species - those overlooked because of their morphological similarity? Despite its wide-ranging implications for biology and conservation, the answer remains open to debate. Butterflies constitute the best-studied invertebrates, playing a similar role as birds do in providing models for vertebrate biology. An accurate assessment of cryptic diversity in this emblematic group requires meticulous case-by-case assessments, but a preview to highlight cases of particular interest will help to direct future studies. We present a survey of mitochondrial genetic diversity for the butterfly fauna of the Iberian Peninsula with unprecedented resolution (3502 DNA barcodes for all 228 species), creating a reliable system for DNA-based identification and for the detection of overlooked diversity. After compiling available data for European butterflies (5782 sequences, 299 species), we applied the Generalized Mixed Yule-Coalescent model to explore potential cryptic diversity at a continental scale. The results indicate that 27.7% of these species include from two to four evolutionary significant units (ESUs), suggesting that cryptic biodiversity may be higher than expected for one of the best-studied invertebrate groups and regions. The ESUs represent important units for conservation, models for studies of evolutionary and speciation processes, and sentinels for future research to unveil hidden diversity. -
Breeding Biology of Asian House Martin Delichon Dasypus in a High-Elevation Area
FORKTAIL 28 (2012): 62–66 Breeding biology of Asian House Martin Delichon dasypus in a high-elevation area ZHIXIN ZHOU, YUE SUN, LU DONG, CANWEI XIA, HUW LLOYD & YANYUN ZHANG We present data on the breeding biology of the largest known colony of Asian House Martin Delichon dasypus, located in the Jiangxi Wuyishan Nature Reserve at 2,158 m in the Huanggang Mountains, China. Nest surveys conducted in abandoned buildings in a subalpine meadow during March–August 2007 and 2008 yielded 163 and 132 clutches, from 84 and 82 nests, respectively. Breeding pairs also laid multiple broods and replacement clutches. Average clutch size was 3.0 and 2.6 eggs for first and second broods respectively. Synchronous hatching was detected in 79% of clutches. The proportion of eggs hatching was 0.7 and 0.6 for first and second broods respectively, and the proportion fledging was 0.5 and 0.4 respectively. Nests situated inside buildings were more successful than those situated outside owing to greater protection from severe weather, which was the major cause of breeding failure. Nest losses caused by severe weather were more pronounced later in the breeding season. INTRODUCTION Nest surveys The 3-ha study area is predominately subalpine meadow habitat in Many bird species raise only one brood per year because of a narrow which are situated more than 30 abandoned buildings and garages period of suitable environmental conditions which prohibits that provide suitable nesting substrate for the breeding martins.

Migratory Birds of Ladakh a Brief Long Distance Continental Migration

It also touches “West Asian- East African Flyway”. Presence of number of high-altitude wetlands (>2500 m amsl altitude) with thin human population makes Ladakh a suitable habitat for migration and breeding of continental birds, including wetlands of very big size (e.g., Pangong Tso, Tso Moriri, Tso Kar, etc.). C O M M O N S A N D P I P E R Ladakh provides a vast habitat for the water birds through its complex Ladakh landscape has significance network of wetlands including two being located at the conjunction of most important wetlands (Tso Moriri, four zoogeographic zones of the world Tso Kar) which have been designated (Palearctic, Oriental, Sino-Japanese and as Ramsar sites. Sahara-Arabian). In India, Ladakh landscape falls in Trans-Himalayan Nearly 89 bird species (long distance biogeographic zone and two provinces migrants) either breed or roost in (Ladakh Mountains, 1A) and (Tibetan Ladakh, and most of them (59) are Plateau, 1B). “Summer Migrants”, those have their breeding grounds here. Trans-Himalayan Ladakh is an integral part of the "Central Asian Flyway" of migratory birds which a large part of the globe (Asia and Europe) between Ladakh also hosts 25 bird species, during their migration along the Central Asian Flyway, as “Passage Migrants” which roost in the region. -
