Individual repeatability in timing and spatial flexibility of migration routes of trans-Saharan migratory raptors

引用

Current Zoology 2014年第5期60卷 642-652页

作者： Pascual LOPEZ-LOPEZ Clara GARCLA-RIPOLLES Vicente URIOS Vertebrates Zoology Research Group CIBIO Research Institute University ofAlicante Edificio Ciencias III Apdo. 99 E-03080Alicante Spain

Satellite-tracking technology has allowed scientists to make a quantum leap in the field of migration ecology. Nowadays, the basic description of migratory routes of many species of birds has been reported. However, the investigation of bird migration at individual level （i.e. repeatability in migratory routes and timing） still remains seldom explored. Here, we investigated repeated migratory trips of a trans-Saharan endangered migratory raptor, the Egyptian Vulture Neophron percnopterus, tracked by GPS satellite telemetry. We compared between- and within-individual variation in migratory routes and timing in order to assess the degree of repeatability （or conversely, the flexibility） in migration. To this end, we analysed a dataset of 48 trips （23 springs and 25 autumns） recorded for six adult birds during 2007-2013. Our results showed consistent migration timing at the individual level, both in spring and autumn. Interestingly, there was a high degree of flexibility in the routes followed by the same individual in different years, probably due to variations in meteorological conditions. Contrary to expectations of a faster migration in spring than in autumn owing to a time-minimization strategy for breeding, birds spent less time in autumn migration （13 ± 2 days, range = 9-18 d） than in spring migration （19 ± 3 days, range = 13-26 d）, which can be explained by differences in environmental con- ditions en route. Egyptian vultures showed a consistent clockwise loop migration through western Africa, following more easterly routes in autumn than in spring. Finally, our results provide supporting evidence of low phenotypic plasticity in timing of migration （i.e. strong endogenous control of migration） and high flexibility in routes [Current Zoology 60 （5）： 642-652, 2014].

Preliminary notes on brain weight variation across labrid fish species with different levels of cooperative behaviour

Brain size and weight vary tremendously in the animal kingdom. It has been suggested that brain structural develop- ment must evolve balanced between the advantages of dealing with greater social challenges mad the energetic costs of maintain- ing and developing larger brains. Here we ask if interspecific differences in cooperative behaviour （i.e. cleaning behaviour） are related to brain weight variations in four close-related species of Labrid fish： two are obligatory cleanerfish throughout their en- tire life （Labroides dimidiatus and L. bicolor）, one facultative cleaner fish Labropsis australis and one last species that never en- gage in cleaning Labrichthys unilineatus. We first search for the link between the rate of species＇ cooperation and its relative brain weight, and finally, if the degree of social complexity and cooperation are reflected in the weight of its major brain sub- structures. Overall, no differences were found in relative brain weight （in relation to body weight） across species. Fine-scale dif- ferences were solely demonstrated for the facultative cleaner L. australis, at the brainstem level. Furthermore, data visual exami- nation indicates that the average cerebellum and brainstem weights appear to be larger for L. dimidiatus. Because variation was solely found at specific brain areas （such as cerebellum and brainstem） and not for the whole brain weight values, it suggests that species social-ecological and cognitive demands may be directly contributing to a selective investment in relevant brain areas. This study provides first preliminary evidence that links potential differences in cognitive ability in cooperative behaviour to how these may mediate the evolution of brain structural development in non-mammal vertebrate groups .

Out of Africa: Miocene Dispersal, Vicariance, and Extinction within Hyacinthaceae Subfamily Urgineoideae

引用

Journal of Integrative Plant Biology 2013年第10期55卷 950-964页

作者： Syed Shujait Ali Martin Pfosser Wolfgang Wetschnig Mario Martínez Azorín Manuel B.Crespo Yan Yu Institute of Plant Sciences Karl Franzens University Graz Biocenter Linz Institute of Biotechnology and Microbiology University of Swat cibio (Instituto Universitario de la Biodiversidad) Universidad de Alicante Key Laboratory of Bio Resources and Eco Environment of Ministry of Education College of Life Sciences Sichuan University

Disjunct distribution patterns in plant lineages are usually explained according to three hypotheses： vicariance, geodispersal, and long-distance dispersal. The role of these hypotheses is tested in Urgineoideae （Hyacinthaceae）, a subfamily disjunctly distributed in Africa, Madagascar, India, and the Mediterranean region. The potential ancestral range, dispersal routes, and factors responsible for the current distribution in Urgineoideae are investigated using divergence time estimations. Urgineoideae originated in Southern Africa approximately 48.9 Mya. Two independent dispersal events in the Western Mediterranean region possibly occurred during Early Oligocene and Miocene （29.9-8.5 Mya） via Eastern and Northwestern Africa. A dispersal from Northwestern Africa to India could have occurred between 16.3 and 7.6 Mya. Vicariance and extinction events occurred approximately 21.6 Mya. Colonization of Madagascar occurred between 30.6 and 16.6 Mya, after a single transoceanic dispersal event from Southern Africa. The current disjunct distributions of Urgineoideae are not satisfactorily explained by Gondwana fragmentation or dispersal via boreotropical forests, due to the younger divergence time estimates. The flattened winged seeds of Urgineoideae could have played an important role in long- distance dispersal by strong winds and big storms, whereas geodispersal could have also occurred from Southern Africa to Asia and the Mediterranean region via the so-called arid and high-altitude corridors.

Conflictive management of small mammals considered as pests： A long way to evidence-based policy making

引用

Current Zoology 2012年第2期58卷 353-357页

This paper discusses the controversial management decisions made by policy-makers worldwide regarding poisoning campaigns aimed to control small mammal populations, often considered harmful economic pests. Aside from considerations re- garding the biological consequences of these campaigns, we argue that when society rejects all values of science and expertise then only badly supported and negligent decisions will be made about conservation and management issues. The extermination of small mammal species, some of which play crucial ecological roles in several regions of the world, is just an example of such discredit and misinformation. Without a strong commitment towards evidence-based policy-making, economic investments in re- search and development could be entirely compromised
