| 摘要： | Habitat loss and fragmentation have a significant negative effect on amphibian species, particularly those with specialized habitat requirements. The endangered farmland green treefrog (Zhangixalus arvalis) primarily inhabits woodlands of agricultural landscapes in central Taiwan. Recently, due to increased demands for pineapple products, many woodlands, particularly bamboo plantations, were converted to pineapple fields. This study aimed to quantify the effect of habitat loss and fragmentation on Z. arvalis due to changes in land cover in an agricultural landscape. The study area contained 34,243 50 m × 50 m grids. In 2006 and 2014–2015, we used acoustic surveys to survey the occurrence of Z. arvalis in each grid. We obtained satellite images of the study area for 2006 and 2014, and we assigned the land-cover type of each grid to one of the following six types: woodland, brushland, cropland, bareland, manmade structures and water body. We examined whether Z. arvalis preferred a certain land-cover type by comparing the proportion of cover types available and the proportion of cover types used by the frogs. Furthermore, we used occurrence records for 2006 and 2014–2015 and applied the Maximum Entropy Model to predict suitable habitat for the respective years. We mapped the loss of suitable habitat and used six indices to quantify habitat fragmentation within the 8 years. We also tested the prediction that the occupancy rate of Z. arvalis in different-sized habitat patches was a function of patch size. Zhangixalus arvalis exhibited a strong preference for woodland, but avoided cropland and manmade structures. From 2006 to 2014–2015, the suitable habitat decreased 4.1%, and all six indices showed an increase in habitat fragmentation. The occupancy rate of different-sized woodland patches was positively correlated with patch size. Mapping suitable habitat and identifying the potential gaps in functional habitat connectivity can be used to guide effective measures for conserving Z. arvalis. |

| 摘要： | Urban habitats are often studied as green fragments in a developed landscape, with opinions diverged on the importance of local versus landscape effects. We propose to replace this “local” versus “landscape” framework with a more precise construct using urban greenspace as the focal scale. Within-greenspace heterogeneity was defined by the multiple elements within each greenspace, whereas beyond-greenspace heterogeneity was defined by the green versus grey elements surrounding each greenspace. The avifauna species in 283 Taipei greenspaces were surveyed and analyzed using this framework. The urban avifauna was found to be associated with five different habitat types, conferring upcoming opinions that highlight the importance of fine-scaled heterogeneity in urban landscapes. Within-greenspace factors were more important than beyond-greenspace ones in explaining species composition and richness. Isolation effects were found only for birds associated with forests but not others because the large natural areas around the city were all forests. Although the city sits at the convergence of two rivers, the tall-grass/shrub and water-related birds associated with riparian systems were poorly represented. Synanthropics and exotics were mostly open woodland and ground/short-grass birds, whose habitat preferences overlapped with human preferences in landscaping. This suggests that human preferences in landuse and landscaping may affect ecosystems in ways beyond mere fragmentation. Ecosystem types that coincide in location with human preference in landuse or exhibit physical structures that do not meet human preferences are particularly at risk. The implications of such human impacts should be seriously considered in the conservation of biodiversity in an increasingly human-dominated world. |

| 摘要： | The Taiwan Yuhina (Yuhina brunneiceps) and White-eared Sibia (Heterophasia auricularis) are nectar-feeding babblers endemic to Taiwan. We describe the morphological features of the brushtipped tongues of these species. The tongue divides into two parts and then into four parts towards the distal end for both species. The tongues of the Taiwan Yuhina and White-eared Sibia are specialized organs adapted for collection of nectar. |

| 摘要： | The natural variation in stable water isotope ratio data, also known as water isoscape, is a spatiotemporal fingerprint and a powerful natural tracer that has been widely applied in disciplines as diverse as hydrology, paleoclimatology, ecology and forensic investigation. Although much effort has been devoted to developing a predictive water isoscape model, it remains a central challenge for scientists to generate high accuracy, fine scale spatiotemporal water isoscape prediction. Here we develop a novel approach of using the MODIS-EVI (the Moderate Resolution Imagining Spectroradiometer-Enhanced Vegetation Index), to predict d18O in precipitation at the regional scale. Using a structural equation model, we show that the EVI and precipitated d18O are highly correlated and thus the EVI is a good predictor of precipitated d18O. We then test the predictability of our EVI-d18O model and demonstrate that our approach can provide high accuracy with fine spatial (2506250 m) and temporal (16 days) scale d18O predictions (annual and monthly predictabilities [r] are 0.96 and 0.80, respectively). We conclude the merging of the EVI and d18O in precipitation can greatly extend the spatial and temporal data availability and thus enhance the applicability for both the EVI and water isoscape. |

| 摘要： | Aim: To estimate whether species have shifted at equal rates at their leading edges (cool boundaries) and trailing edges (warm boundaries) in response to climate change. We provide the first such evidence for tropical insects, here examining elevation shifts for the upper and lower boundaries shifts of montane moths. Threats to species on tropical mountains are considered.
Location: Mount Kinabalu, Sabah, Malaysia.
Methods: We surveyed Lepidoptera (Geometridae) on Mount Kinabalu in 2007, 42 years after the previous surveys in 1965. Changes in species upper and lower boundaries, elevational extents and range areas were assessed. We randomly subsampled the data to ensure comparable datasets between years. Estimated shifts were compared for endemic versus more widespread species, and for species that
reached their range limits at different elevations.
Results: Species that reached their upper limits at 2500–2700 m (n 28 species, 20% of those considered) retreated at both their lower and upper boundaries, and hence showed substantial average range contractions (-300 m in elevational extent and -45 km2 in estimated range area). These declines may be associated with changes in cloud cover and the presence of ecological barriers (geological and vegetation transitions) which impede uphill movement. Other than this group, most species (n 109, 80% of the species considered) expanded their upper boundaries upwards (by an average of 152 m) more than they retreated at their lower boundaries (77 m).
Main conclusions: Without constraints, leading margins shifted uphill faster than trailing margins retreated, such that many species increased their elevational extents. However, this did not result in increases in range area because the area of land available declines with increasing elevation. Species close to a major
ecological/geological transition zone on the mountain flank declined in their range areas. Extinction risk may increase long before species reach the summit, even when
undisturbed habitats are available. |

| 摘要： | We examined d15N and d13C values of feathers from nine species, belonging to three feeding guilds (herbivores, omnivores, and insectivores), of wild passerines at eight sites along an altitudinal gradient (339-2,876 m asl) within Taroko National Park, Taiwan. We examined: (1) if altitudinal patterns in feather d15N and d13C are consistent with previously published values for plants and soils, (2) if feather d15N and d13C differ among sites, and (3) if there are year-toyear and/or month-to-month fluctuations in feather d15N and d13C of the same birds. We found no simple relationship between feather isotope values and altitude. Feather d15N values decreased significantly with increasing altitude for insectivores, but not for herbivores and omnivores. Feather d13C values increased significantly with increasing altitude for herbivores and omnivores, but not for insectivores. Altitudinal trends in feather d15N and d13C values exhibit even more inconsistent patterns when data were analyzed by species; feather d15N and d13C values for some species increased significantly with increasing altitude, others decreased significantly with increasing altitude, and still others exhibited no significant relationship between isotopic values and altitude. The R2 for the relationship between feather d15N, d13C values and altitude was generally low regardless of whether the analysis was by feeding guilds or species. This indicates much of the variation cannot be explained by altitude. There were either no significant differences between sites, or significant differences between some but not all sites when investigating d15N or d13C, whether by feeding guilds or by species. Our study suggests that carbon and nitrogen isotopes may be not useful markers to track altitudinal migration of montane passerines. |

| 摘要： | Physiological research suggests that tropical insects are particularly sensitive to temperature, but information on their responses to climate change has been lacking—even though the majority of all terrestrial species are insects and their diversity is concentrated in the tropics. Here, we provide evidence that tropical insect species have already undertaken altitude increases, confirming the global reach of climate change impacts on biodiversity. In 2007, we repeated a historical altitudinal transect, originally carried out in 1965 on Mount Kinabalu in Borneo, sampling 6 moth assemblages between 1,885 and 3,675 m elevation. We estimate that the average altitudes of individuals of 102 montane moth species, in the family Geometridae, increased by a mean of 67 m over the 42 years. Our findings indicate that tropical species are likely to be as sensitive as temperate species to climate warming, and we urge ecologists to seek other historic tropical samples to carry out similar repeat surveys. These observed changes, in combination with the high diversity and thermal sensitivity of insects, suggest that large numbers of tropical insect species could be affected by climate warming. As the highest mountain in one of the most biodiverse regions of the world, Mount Kinabalu is a globally important refuge for terrestrial species that become restricted to high altitudes by climate warming. |

| 摘要： | We used 2 species accumulation functions to fit observed data and determine appropriate point-count durations and sample sizes for bird surveys in 3 vegetation types during both breeding and non-breeding seasons. We conducted fieldwork in a grassland, a coniferous forest, and a broadleaf forest in subtropical Taiwan from October 1999 to January 2000 and from March to June 2000. In almost all cases, both the linear dependence model and the Clench model fit the observed data very well. We calculated the duration of point counts required to reach 80% of the predicted asymptote. The point-count duration required in the breeding season was 1 min for the grassland, 2 min for the coniferous forest, and 3 min for the broadleaf forest. During the non-breeding season, the required duration was 3 min for the grassland, 9 min for the coniferous forest, and 6 min for the broadleaf forest. The required samples depend on the goals of a survey, the season, and vegetation types. Our results demonstrate that bird detections vary between seasons and vegetation types. Therefore, when determining the durations and sample sizes of pointcounts, investigators should consider characteristics of the detection patterns of the bird communities. We show that asymptotic models can be used to examine these patterns in an objective and rigorous way. |

| 摘要： | 排序(ordination)是探討生物群聚與環境之間關係常用的多變數統計方法。本研究以模擬數據及鳥類群聚資料，探討主成分分析(principal components analysis, PCA)、對應分析(correspondenceanalysis, CA)、以及降趨對應分析(detrended correspondence analysis,DCA)三種常用的排序法在不同群聚變異梯度長度下的排序表現。結果發現三種排序法適用的群聚梯度長度不同。DCA運算結果的軸長可作為群聚梯度長度判斷的參考；梯度軸長在2 SD以上，且CA因為物種沿環境梯度的非線性分布而產生明顯拱形效應(arch effect)時，以DCA的結果較佳；但若樣點在CA的空間未有明顯拱形排列時，則以使用CA較適當。軸長在2 SD以下時，以使用CA及PCA較佳，DCA則可能因為降趨(detrending)及重新刻劃(rescaling)的程序，而嚴重扭曲數據原本蘊含的生態意義。排序方法的選擇應考慮生物群聚之梯度長度，以獲得合理的結果。 |

| 摘要： | 魚塭經營管理強度可能影響棲息的鳥類群聚。台灣黑面琵鷺保育學會於2004-2017年在台南七股地區進行長期鳥類調查；其中的魚塭樣區於2009年之前為低度維護管理狀態，2010年之後則為文蛤養殖池。本研究分析該魚塭樣區十一月至翌年二月冬季鳥類資料，以了解不同魚塭管理強度對冬季鳥類群聚結構的影響。結果發現從低度維護管理魚塭轉變為高強度管理的文蛤養殖池後，鳥種數從平均21種減少為12種，總個體數從平均688隻，驟減為102隻；而游禽數量從平均463隻遽減為5隻，減幅達99%；涉禽數量則從平均193隻減少為81隻，減幅約58%。文蛤養殖池約3年曬池1次，研究樣區沒有因為曬池形成淺水泥灘而顯著增加涉禽數量。研究結果發現低度維護管理魚塭的鳥種多樣性非常高，應盡力保存。認為魚塭恢復水產養殖後，曬池作業可以增加涉禽的可利用棲地，則是不切實際的想法。 |

| 摘要： | 動物調查努力量大多固定，例如在所有棲地與季節以相同次數或頻度進行調查。但是群聚結構與個體偵測率可能隨空間或時間而有所變異；固定努力量可能使不同樣本之間的代表性或完整性不同，從而導致錯誤結論。本研究以6個物種—豐富度模型建構人工群聚，並以7個偵測率模擬抽樣，說明不同群聚結構及偵測率，需要的努力量不同。另以臺南大凍山低海拔闊葉林及七股濕地鳥類資料，實證不同棲地與季節需要不同的努力量；資料分析結果亦發現普遍採行的每月1次調查頻度及環保署環評技術規範的努力量大多嚴重不足。依據本研究結果，建議未來應避免在所有棲地與季節以相同努力量調查動物群聚，並在調查過程隨時評估樣本完整性。本研究也提出動物調查實施流程及停止調查之決策程序。 |

Predicting biodiversity distributions and identifying the hotspots are essential in order to design
strategies for biodiversity conservation. Lu (2016) proposed a process to estimate biodiversity hotspots
based on the probabilities computed from species distribution models (SDM), using Taiwans endemic
bird species as an example. However, we found that Lus methods were seriously flawed in ecological
concepts and scientific logic, and could be misleading in the formulations of academic research or
conservation policies. We used a dataset on endemic bird species from the Taiwan Breeding Bird Survey
project to build two biodiversity maps: one based on Lus process and the other one based on binary (i.e.,
presence/absence) SDMs, a general method reported in the literature. We tested the predicted hotspots
from both maps against a set of known hotspots, and found that Lus methods severely underperformed
compared to the general method. We therefore urge that the methods of Lu (2016) should not to be used
anymore in biodiversity hotspot analyses or habitat-risk assessments. |

| 摘要： | 定點計數與霧網捕捉法是鳥類群聚調查常用的方法。定點計數法效率高，但不易察覺隱密鳥種。相反地，霧網捕捉法較易調查到隱密鳥種，但必須投入大量人力及時間。兩種方法察覺到的鳥種特性不同，但調查得到的鳥類群聚結構差異卻很少被討論。我們於 2012 年 4 月至 9 月，在臺南龍崎海拔約 100 m 之灌叢與高草地，分別以這兩種方法調查鳥類。我們比較兩種方法得到的鳥類資料，包括鳥種組成、種類多樣性及鳥類的生物與生態特性。調查期間共記錄到 17 種，513 隻次。
其中，定點計數法 12 種，413 隻次；霧網捕捉法 13 種，100 隻次。兩種方法得到的種類多樣性類似，但鳥種組成相似性不高，Jaccard similarity index 僅 0.47。定點計數法不易察覺相對密度較低或不善鳴叫的鳥種；霧網捕捉法則不易捕獲體型較大或相對翼長較短的鳥類。我們認為在低海拔灌叢進行鳥類調查時，單獨採用定點計數或霧網捕捉法，均可能嚴重低估樣區的鳥種多樣性；僅採用其中一種方法調查鳥類，對於結果的詮釋，應特別謹慎。 |

| 摘要： | 四草野生動物保護區當中的高蹺?繁殖區(A1)及北汕尾水鳥保護區(A2)，於2002-2004年之間陸續進行大規模棲地改善工程，目的在增加高蹺?繁殖族群及提昇鳥類多樣性。我們在2003年12月至2010年7月於保護區進行鳥類調查，並對照鹿耳門溪北岸廢棄魚塭的同期鳥類調查資料，以及A2區1998-2000年的施工前文獻資料，評估該項工程是否達到預期效果。結果發現A1區在施工之後，繁殖期高蹺?族群量並未逐年增長；度冬期水鳥群聚結構則在2003-2005年之間發生劇烈變動，兩年內物種轉換率達52%，主要改變為水岸高草游涉禽增加、水域泥岸涉禽減少；2005年之後群聚結構才趨於穩定。A2區在棲地改善工程之後，候鳥度冬期的水鳥總個體數並未增加，種類多樣性則非但未增加，甚且逐年遞減；2003-2009年之間水鳥種類多樣性減少21%。A2區施工前的度冬期水鳥群聚結構，在1998-2003年之間沒有明顯變動。但施工及完工之後，於2003-2009年之間，則持續呈現具方向性之改變，主要是水岸高草游涉禽增加、泥灘涉禽減少。由於對照樣區群聚結構在此期間呈穩定狀態，顯示A1及A2區鳥類群聚結構劇烈變動為獨立事件，其原因極可能來自棲地改善工程。是項工程沒有成功增加A1區高蹺?繁殖族群，而在A2區，非但未使水鳥種類多樣性增加，反而導致其嚴重銳減。是項工程的必要性未經科學評估，亦未明確釐清課題，且基礎生態資訊掌握不足，導致規劃失當。然而棲地改善的成效評估及生態監測報告並未指出工程未達預期效益之問題，主要原因是監測缺乏目標、抽樣及分析不當、以及結果未正確解讀。我們認為任何棲地改善或復育工程均必須基於生態學資料，並廣納各界建言，避免僅根據特定少數人意見而為之。 |

| 摘要： | 本研究探討搭配鳥音回播的定點計數是否可以提升鳥類相調查效率。在台南縣崁頭山海拔75-660 m地區進行實驗。結果發現，搭配鳥音回播在定點需要停留更久時間，但明顯減少需要的樣本數。回播使調查到的總鳥種數較少，但可以增加調查到的總個體數。本研究鳥音回播與定點計數同時進行，以致對調查者造成干擾，無法完全達到預期結果。我們認為在非繁殖季明顯缺乏鳥音線索的中高海拔山區的鳥類相調查，搭配鳥音回播的定點計數仍值得嘗試；並應採取播放一段時間之後，關掉音源再進行調查。雖然增加額外的鳥音播放時間，但應該可以有效減少樣本數；對於路途遙遠或可及性較低的中高海拔山區而言，有其應用上的價值。 |

| 摘要： | In order to examine fidelity to migration route, breeding, wintering, and stopover sites, we analyzed the migration of two adult Grey-faced Buzzards Butastur indicus and an adult Honey-buzzard Pernis apivorus that were satellite-tracked in East Asia for more than two migration seasons. The Grey-faced Buzzards showed a high degree of route fidelity across seasons and years. On the other hand, the migration routes of the Honey-buzzard were distinctly different between fall and spring seasons, whereas, within each season they were roughly similar between years. All three raptors were strictly faithful to their breeding and wintering sites. They also showed fidelity to several stopover sites in which the raptors stayed for relatively long periods to replenish energy. Our findings have important implications for the conservation of the migratory raptors. |

| 摘要： | We documented body measurements of birds captured during 1987-1995 banding research in Taiwan by Taipei Wild Bird Society. A total of 223 bird species with measurements of body mass, length of body, head, tail, bill and tarsus, and maximum wing span were compiled for the database. Body mass, length of bill, and length of tarsus of 85 species that had sample sizes > 20 were reported. In addition, we also compared our data with that from Dunning (1993). Among the ten species eligible for further analyses, we found that eight species showed significant differences in body mass between our data and that of Dunning (1993). Our results together with our recent studies (Lee et al, 2004; Ding et al., 2005) showed that compiling banding research data contribute to predict ecological parameters of bird studies in community, ecosystem and landscape levels. |

| 摘要： | We satellite-tracked the migration of two adult and one young Honeybuzzards Pernis apivorus between the Japanese breeding ground and Southeast Asia. In autumn migration, the two adults (A1 and A2) migrated across the East China Sea, then through China, the Indochina and Malay Peninsula, and Sumatra. After Sumatra, A1 arrived in Java for the winter, while A2 moved up through Borneo and reached Mindanao, the Philippines. The young honey-buzzard moved along the coast of the South China Sea to reach the Malay Peninsula for the winter. In spring migration, A1 went up the Malay Peninsula, and then took a route different from its autumn route, moving up inland China, down to North and South Korea, and arrived at the previous breeding site in Japan. A2 followed the autumn route and reached a stopover site in Cambodia. After an undetermined radio silence, it was rediscovered back at its breeding area in Japan. The young stayed at the wintering site, making no apparent effort to get back to the breeding area. The sample size is limited, but these results suggest that the migration of Honey-buzzards is remarkably convoluted and varies considerably with bird age and season. |

| 摘要： | Seasonal variations in the distribution of bird species richness and community composition along elevational gradients in Taiwan were studied. We compiled bird species richness data through an extensive literature review, and classified the data into breeding season, nonbreeding season, and year-round sets. We then examined the avifaunal-environmental relationships using presence/absence data by principle components analysis (PCA), cluster analysis, and detrended correspondence analysis (DCA). With the year-round dataset, species richness appeared roughly constant from sea level to about 1500 m, then declined with increasing elevation; while the richness during the breeding season was non-linearly related to elevation, with a hump-shaped curve which peaked at around 1500 m. By separating migratory landbirds from residents during the non-breeding season, however, we found that the two groups had different patterns along the gradient: residents showed a hump-shaped pattern similar to that of the breeding season, whereas migratory landbirds showed a negative exponential pattern. The results of PCA and cluster analysis demonstrated that the resident assemblages were classified into three major categories: lowlands, mid-elevation domain, and highlands, separated roughly by the elevations of 300 and 2300 m. DCAs indicated that elevation and human disturbance are the major environmental factors contributing to variations in the trend of resident assemblages. The seasonality of data collection strongly influences bird species richness distribution patterns and should be clearly defined to obtain a meaningful result in bird species richness studies. |
