“…In addition, temporal shifts in plant phenology generate cascading effects on organisms at higher trophic levels [2,8,31]. The progress of spring at a given date can thus be conveniently expressed by degree-days (DD; the sum of mean daily temperatures above a given threshold from a biologically meaningful start date till the date of interest) indices, which summarize the thermal conditions affecting phenology ( [27][28][29]; see also electronic supplementary material), although, to the best of our knowledge, this approach has never been applied in the studies of avian phenology [32].…”

“…Moreover, information on the progress of spring events on a daily basis obtained in a methodologically consistent way across decades and diverse geographical regions does not exist for individual plant and invertebrate species, not to mention entire communities. However, at medium and high latitudes, the phenophases and development of plants and ectothermic animals that birds use as, for example, food are strongly dependent on weather, and temperature qualifies as the most important factor [24][25][26][27][28][29], although other factors (e.g. photoperiod; see [30]) can also intervene.…”

Climate warming, ecological mismatch at arrival and population decline in migratory birds

et al. 2010

Climate is changing at a fast pace, causing widespread, profound consequences for living organisms. Failure to adjust the timing of life-cycle events to climate may jeopardize populations by causing ecological mismatches to the life cycle of other species and abiotic factors. Population declines of some migratory birds breeding in Europe have been suggested to depend on their inability to adjust migration phenology so as to keep track of advancement of spring events at their breeding grounds. In fact, several migrants have advanced their spring arrival date, but whether such advancement has been sufficient to compensate for temporal shift in spring phenophases or, conversely, birds have become ecologically mismatched, is still an unanswered question, with very few exceptions. We used a novel approach based on accumulated winter and spring temperatures (degree-days) as a proxy for timing of spring biological events to test if the progress of spring at arrival to the breeding areas by 117 European migratory bird species has changed over the past five decades. Migrants, and particularly those wintering in sub-Saharan Africa, now arrive at higher degree-days and may have therefore accumulated a 'thermal delay', thus possibly becoming increasingly mismatched to spring phenology. Species with greater 'thermal delay' have shown larger population decline, and this evidence was not confounded by concomitant ecological factors or by phylogenetic effects. These findings provide general support to the largely untested hypotheses that migratory birds are becoming ecologically mismatched and that failure to respond to climate change can have severe negative impacts on their populations. The novel approach we adopted can be extended to the analysis of ecological consequences of phenological response to climate change by other taxa.

“…Since development of immature insects is temperature dependent, PMI is normally calculated by the accumulated degree day/hour (ADD/ADH) model (measure of thermal time taken to reach each developmental event, K) which is associated with basal temperature called the lower temperature threshold or the developmental zero (temperature below which development ceases) value [30,31].…”

Lucilia cuprina is one of the forensically important Calliphoridae fly. L. cuprina is a helpful resource at the crime scenes as well as a nuisance to sheep. It is known to be one of the first flies to occupy a corpse upon its death. Due to this, it has great importance in forensic field to find out post-mortem interval. In this study, the development of L. cuprina is studied in an incubator at different constant temperatures. Larvae of the L. cuprina were reared in an incubator at 20 º C, 25 º C, 30 º C, 35 º C, and 40 º C. During study the developmental data, temperature and relative humidity of the rearing room as well as weight, length of the larvae were recorded from the time the larvae were collected until the adult flies emerge out.Results obtained show that development of the L. cuprina was slow at lower temperature. At the high temperature, developmental rate was fast. At low temperature L. cuprina attained greatest body weight whereas at high temperature there was a decrease in the weight. When flies were reared at 40 º C the development of the fly was much more rapid but slight mortality was observed. Above study shows that temperature plays a very important role in the development of L. cuprina. For the correct estimation of post-mortem interval this study is very useful, because each dipteran fly has its own developmental period with respect to temperature and region.

“…Degree-days have been used in phenological analysis applied to different kind of crops, both in temperate zones (Narwal et al, 1986;Allen and O'brien, 1986;Undersander and Christiansen, 1986;Jones et al, 1991;Sharratt et al, 1989;Spencer et al, 2000;Spencer and Ksander, 2006) and in tropical zones as well (Lemos et al, 1997;McBeth et al, 2001;Bell and Wright, 1998;Jullien et al, 2008;Guan et al, 2009). Degree-days also have been used in insect phenology studies (Tokeshi, 1985;Lindblad and Sigvald, 1996;Hart et al, 1997;Broufas and Koveos, 2000;Milonas et al, 2001;Olsen, 2003;Hirata and Higashi, 2008;Kumral et al, 2008;Naves and Sousa, 2009;Nietschke et al, 2007;Elliot et al, 2009).…”

Comparison of eight degree-days estimation methods in four agroecological regions in Colombia

2012

Eight methods were used to estimate degree-days in four Colombian localities. Four methods have been previously proposed in literature: Simple Sine, Double Sine, Simple Triangle, and Double Triangle methods. The other four methods are proposed in this research: Simple Logistic, Double Logistic, Simple Normal, and Double Normal. The estimation of the degree-days through hourly temperature values was used as the reference standard method, and the four localities from where the temperature values were taken were the municipalities of Cajicá (Cundinamarca), Santa Elena (Antioquia), Carepa (Urabá Antioqueño), and Ciudad Bolivar (Zona cafetera Antioqueña). Degree-days obtained by all methods under study were compared through linear regression to those obtained by the reference standard method. There were differences in the correlation of each method to the reference when compared within each region and among regions. The Simple Logistic and Double Logistic methods showed the best performance with acceptable R 2 values and considerably lower bias than the other methods. The poorest fit was found in Cajicá, where the average R 2 was 0.571. For the regions of Santa Elena and Carepa, the average R 2 was 0.756 and 0.733. The best fit was found in Ciudad Bolivar, with an average R 2 of 0.826.Key words: degree-days, thermal time, temperature threshold, statistical modeling. Comparação de oito métodos para calcular graus-dia em quatro regiões agroecológicas ResumoEstimativas de graus-dia foram obtidas pelos métodos de seno simples e duplo, triangulo simples e duplo, as quais são amplamente utilizadas. Quatro novos métodos foram propostos e avaliados nesta pesquisa: logística simples e dupla, normal simples e dupla, baseadas em regressão logística e distribuição normal. Registros horários de temperatura obtidos em Cajicá (Cundinamarca), Santa Elena (Antioquia), Carepa (Urabá Antioqueño) e Ciudad Bolivar (Região tradicional da cultura do café) foram utilizados para obter estimativas da soma térmica com maior precisão sendo, portanto, considerada como a referên-cia para comparação utilizando regressão linear. Foram constatadas diferenças entre o ajuste dos métodos dentro de cada região e entre regiões. Foram observados os maiores coeficientes de determinação (R 2 ), nos métodos de logística simples e logística dupla. O menor coeficiente de determinação, de 0,571, foi obtido em Cajicá enquanto nas regiões de Medellín e Carepa, o R 2 foi de 0,756 e 0,733 respectivamente. O melhor ajuste foi obtido em Ciudad Bolivar, com um R 2 igual a 0,826.Palavras-chave: graus-dia, tempo térmico, temperatura basal, modelagem estatística.
